Creabilis released results from a phase IIb trial of CT327 for the treatment of chronic pruritus in psoriasis. This randomized, double-blind, placebo-controlled study enrolled 160 patients with chronic pruritus in psoriasis. Subjects received CT327 ointment at 0.05%, 0.1% and 0.5% administered twice daily for eight weeks. Data demonstrated patients receiving CT327 showed a statistically significant and clinically meaningful reduction in pruritus compared to blinded placebo vehicle. Pruritus was measured using a visual analogue scale (VAS), the accepted regulatory endpoint. The reduction from baseline in pruritus VAS reached 60% for CT327 compared to 20% for vehicle alone (p<0.05). A clinically meaningful reduction in pruritus (VAS=20mm) was seen in up to 79% of patients for CT327 compared to 36% for vehicle alone (p<0.05). At baseline, 69% of patients reported at least moderate pruritus (VAS>40mm). An improvement was also seen in the CT327 treated groups versus vehicle in mPASI (modified Psoriasis Area and Severity Index) in all subjects. The drug was safe and well tolerated. Subjects receiving CT327 reported fewer adverse events and withdrawals due to pruritus than the vehicle treated patients.

Idera Pharmaceuticals reported results from a phase II trial of IMO-3100 for the treatment of plaque psoriasis. This randomized, double-blind, placebo-controlled study enrolled 44 patients with moderate to severe plaque psoriasis. Subjects received 0.16mg/kg or 0.32mg/kg or IMO-3100, or placebo, by subcutaneous injection once weekly for four weeks, with a follow-up period through day 57. Results showed on day 57, 48% of patients treated with either dose of IMO-3100 demonstrated statistically significant improvements of 35% to 90% from baseline Psoriasis Area Severity Index (PASI) scores compared with 0 in the placebo cohort (p<0.005). Additionally, analysis of biopsy samples collected from patients during the trial indicated PASI score improvements were associated with significant improvement of psoriasis disease-associated gene profile, including down regulation of activated genes in the IL-17 pathway,which is central to the pathogenesis of psoriasis. IMO-3100 was well tolerated at both dose levels. Based on these data, Idera Pharmaceuticals is planning a 12-week phase II trial of IMO-8400 in psoriasis to initiate in the second half of 2013.

Sanofi and Regeneron Pharmaceuticals issued pooled results from two phase Ib trials of dupilumab for atopic dermatitis. The trials enrolled a total of 67 subjects with moderate-to-severe atopic dermatitis not adequately controlled with topical medications. The subjects were randomized to three different doses of dupilumab (75mg, 150mg or 300mg) or placebo administered as weekly subcutaneous injections for four weeks. The efficacy data showed treatment with dupilumab at either 150mg or 300mg per week significantly improved the signs and symptoms of atopic dermatitis, with significant improvements in body surface area (BSA) score, Investigator Global Assessment (IGA) score and Eczema Area Severity Index (EASI) from baseline to week four, compared to placebo (p<0.05 vs. placebo for all measures and doses). The significant improvements in BSA, IGA and EASI scores were maintained at week eight in the 300mg dose group (p<0.05 vs. placebo). The most common adverse events were nasopharyngitis and headaches. A phase IIa trial is currently underway and a phase IIb trial is planned for later this year.

Novartis reported results from a phase III trial of omalizumab for the treatment of chronic idiopathic urticaria (CIU). This global, multi-center, randomized, double-blind, placebo-controlled study, ASTERIA II, enrolled 323 patients with moderate to severe CIU who remained symptomatic despite treatment with approved antihistamine doses. Subjects received omalizumab 75mg, 150mg or 300mg, or placebo, administered subcutaneously every four weeks, for a total of three doses within a 12-week treatment period, with a 16-week follow-up period. The study met its primary endpoint, showing that omalizumab given at doses of 150mg and 300mg led to significant improvement from baseline at Week 12 in the mean weekly ISS from baseline (approximately 14 in all treatment groups) by 8.1 (p=0.001) and 9.8 (p<0.001), respectively, compared to a 5.1 improvement in patients on placebo. The omalizumab 75mg dose group did not demonstrate statistical significance compared to placebo for the primary endpoint. All eight pre-specified secondary endpoints in the ASTERIA II trial were met for the 150mg and 300mg doses. Omalizumab was well tolerated. The more frequent adverse events were nasopharyngitis, idiopathic urticaria and headache. Novartis regulatory submissions are on track for 2013.

XOMA released interim results from a phase II trial of gevokizumab for the treatment of inflammatory facial lesions. This double-blinded, randomized, placebo-controlled study enrolled 92 patients with inflammatory facial lesions due to moderate to severe acne vulgaris. Subjects received gevokizumab 0.2mg/kg or 0.6mg/kg once a month, or placebo, for three months. Data demonstrated the 0.6mg/kg dose group showed a statistically significant reduction of 19 mean inflammatory lesions on Day 42 compared to a reduction of 13 lesions in the placebo treated group (p=0.077). Each of the groups had a mean baseline of approximately 31 inflammatory lesions. The magnitude of the difference was substantially maintained throughout the study, but differences at later measurement points were not statistically significant. The 0.6mg/kg dose group demonstrated both a clinically and statistically significant improvement in the Investigator Global Assessment (IGA) at Day 84, showing a 31% responder rate versus a 5% responder rate in the placebo group (p=0.031). The 0.2mg/kg dose group showed no clinically or statistically significant differences from placebo at any time point in inflammatory lesion count or in IGA. Gevokizumab was well tolerated. The incidence of adverse events was comparable between both active groups and placebo. Based on these data, XOMA will complete the study and then expect to follow non-infectious uveitis into phase III development with its partner, Servier.

Novartis reported results from a phase II trial of AIN457 (secukinumab) for the treatment of plaque psoriasis. This double-blind, parallel group, placebo-controlled study enrolled 404 patients with moderate to severe psoriasis on the hands, feet and nails. Subjects received AIN457 or placebo once-weekly for four weeks, with an analysic period at 12 weeks. Data showed AIN457 was nearly three times more effective than placebo at reducing plaque psoriasis (54.3% of patients versus 19.2% respectively, p=0.005), as measured by the Investigator’s Global Assessment (IGA). Patients also benefited if they received AIN457 once every four weeks, with 39.0% experiencing either “clear” or “minimal” psoriasis after 12 weeks of treatment. In this same treatment group, significantly more patients experienced improvements in pain and discomfort compared to placebo (36.2% versus -1.5%) from baseline; and in anxiety and depression versus placebo (16.3% versus 6.2%), as measured by EuroQol (EQ-5D). AIN457 was well tolerated. The most frequent adverse events were infections. Novartis will await the results of a large-scale and longer-term phase III study, expected in 2013, before submitting an NDA.

September 24, 2012

DUSA Pharmaceuticals issued results from a phase II trial of Levulan, Kerastick and BLU-U with or without occlusion versus vehicle for the treatment of actinic keratoses (AKs). This multi-center, blinded, randomized, vehicle-controlled study enrolled 70 patients with minimally to moderately thick AKs on the upper extremities. Subjects received Levulan, Kerastick and BLU-U or vehicle, with or without occlusion, for three-hour incubation periods. The study showed a statistically significant lesion reduction and complete clearance of AK of the extremities when compared to treatment with vehicle. At 12 weeks following PDT, the subjects treated with Levulan plus occlusion regimen demonstrated an 89% (p<0.0001) AK lesion clearance rate as compared to a 70% (p<0.0001) clearance rate for those treated without occlusion after up to two PDT treatments; subjects receiving vehicle plus occlusion and vehicle alone demonstrated 17% and 6% lesion clearance rates, respectively. The safety profile was similar to that seen in the current labeling. DUSA will use the data, in combination with anticipated phase II results from another trial, to form the basis for label expansion.

March 19, 2012

Foamix released results from a phase II trial of Minocycline foam for the treatment of impetigo. This randomized, double blind, dose-ranging study enrolled 32 subjects, ages 2 to 15, with impetigo. The subjects received Minocycline foam 1% or 4% twice daily for seven days. They were checked for response on day 14. Clinical response at the end of the treatment was 92% and 100% respectively for the low or high doses; and all subjects (100%) showed success on day 14. In addition, 80% of the total population were cured or improved significantly after three days of treatment. Eight subjects had MRSA and in all of them the bacterial infection was eradicated on day seven. No drug related side effects were reported.

December 19, 2011

Rib-X reported results from a phase IIb trial of delafloxacin for acute bacterial skin and skin structure infections. This randomized, active controlled, double blind trial enrolled 256 adults who received delafloxacin alone (300 mg intravenously every 12 hours), or Zyvox (linezolid) or vancomycin at the recommended doses, both with and without aztreonam. The trial met the primary endpoint, the Investigators Global Assessment of Cure. Clinical cure was reached by 70.4%, 64.9% and 54.1% of subjects in the delafloxacin, Zyvox plus/minus aztreonam and vancomycin plus/minus aztreonam arms, respectively, with statistical superiority in comparison to vancomycin (p≡0.031). In a group of subjects with confirmed MRSA, the clinical cure was reached by 59.3%, 51.5% and 56.3% of subjects in the three arms, respectively. Overall adverse event rates were statistically equivalent across the study arms.

December 12, 2011

Polymedix reported interim results from a phase II trial of PMX-30063 for the treatment of acute bacterial skin and skin structure infections (ABSSI). Data are from 80 subjects with ABSSSI due to either methicillin-susceptible or methicillin-resistant S. aureus. The subjects were randomized to receive either one of three five-day dose regimens of PMX-30063 or the standard of care, daptomycin, for the approved seven-day dose regimen. The combined data for all treatment arms showed a clinical cure rate of 92%, with each of the four dosing arms having clinical cure rates ranging from 87% to 100%. All dose groups were safe and generally well-tolerated.

November 7, 2011

Clinuvel reported results from a phase II trial of afamelanotide for the treatment of Erythropoietic Protoporphyria (EPP). The randomized, double-blind, placebo-controlled study (CUV030) enrolled 77 subjects, 68 of whom completed the trial. The subjects were administered either the afamelanotide implant or placebo at the start of study, after 60 days and 120 days, and were followed up to 180 days. The primary endpoint was to determine whether afamelanotide implants can reduce the severity of phototoxic reactions associated with EPP. Based on analysis of time spent outside, afamelanotide was shown to increase subjects ability to expose their skin to direct sunlight compared to placebo. The subjects who received afamelanotide spent significantly more time in direct sunlight between the most intense hours of 10 AM and 3 PM (p≡0.036) and between 10 AM and 8 PM (p≡0.025). Data from an EPP-specific quality of life assessment also demonstrated an improvement from baseline for subjects receiving afamelanotide compared to placebo at 60 days (p≡0.001), 120 days (p≡0.003) and 180 days (p<0.001). The afamelanotide implant was safe and well-tolerated.

April 25, 2011

Nabriva Therapeutics issued results from a phase II trial of BC-3781 for acute bacterial skin and skin structure infections. This double blind trial enrolled 210 subjects and was designed to compare BC-3781 to Vancomycin, the standard of care. The subjects received 100mg or 150mg of BC-3781 or 1,000mg Vancomycin intravenously twice-daily. Both doses of BC-3781 were comparable to Vancomycin in terms of clinical response: 90% and 89% of subjects treated with 100mg and150mg of BC-3781, respectively, and 92% of the subjects treated with Vancomycin. In addition, the early clinical response was assessed using a composite endpoint (cessation of spread of erythema with a lack of fever) at day three. This endpoint was reached by 83% and 86% of subjects in the 150 mg and 100mg BC-3781 arms, respectively and 80% of subjects in the Vancomycin arm. BC-3781 was well tolerated.

Trius reported positive results from a phase II trial of oral torezolid for the treatment of severe complicated skin and skin structure infections (cSSSI). This randomized, double-blind, dose-ranging study enrolled 188 subjects with cSSSI caused by gram-positive bacteria. Torezolid was administered orally at doses of 200, 300 or 400 mg once-daily for five to seven days. Of the 188 enrolled subjects, 164 were clinically evaluable at the test-of-cure visit. The overall cure rates for severe abscesses, cellulitis and wound infections were 96%, 97% and 90%, respectively. Clinical cure rates by dose in the evaluable population were 98%, 94% and 94% for the 200, 300 and 400 mg doses, respectively. In the group of microbiologically evaluable subjects, clinical cure was achieved in 100%, 93% and 96% of the 200, 300 or 400 mg dose groups, respectively. Torezolid was well tolerated.

February 2, 2009

Rib-X reported positive results from a phase II trial of delafloxacin for the treatment of complicated skin and skin structure infections (cSSSI). This double-blind study enrolled 150 subjects who were treated with delafloxacin dosed intravenously at 300 mg and 450 mg twice a day or tigecycline, the standard of care, for 5 to 14 days. Both doses of delafloxacin were as efficacious as tigecycline in treating the infection. The cSSSI cure rates for delafloxacin 300 mg BID and 450 mg BID were 97.2% and 92.5%, respectively, while the cure rate for tigecycline was 91.2%. The MIC90 (Minimum Inhibitory Concentration required to inhibit the growth of 90% of organisms) values for delafloxacin and tigecycline against all S. aureus isolates was 0.06 and 0.12 micrograms/mL, respectively. Delafloxacin's MIC90 values against all MRSA, including the quinolone-resistant MRSA strains, was also 0.06 micrograms/mL. Delafloxacin was safe and well tolerated. Overall treatment-related adverse events were lower in both the 300 mg and 450 mg dose groups compared to tigecycline. Based on the results, Rib-X plans to move forward with the development of delafloxacin.

June 30, 2008

Forest Labs released positive results from two phase III trials of ceftaroline for the treatment of complicated skin and skin structure infections (cSSSI). These international, randomized, double-blind comparative studies, dubbed CANVAS I and CANVAS II, enrolled 1,396 adult subjects with cSSSI caused by gram-positive and gram-negative bacteria. The primary endpoint was non-inferiority of ceftaroline compared to vancomycin plus aztreonam, with a non-inferiority margin of 10%. This endpoint was reached; the ceftaroline arm had a clinical cure rate of 91.6% compared to a 92.7% clinical cure rate in the vancomycin plus aztreonam arm. In addition, ceftaroline had a microbiological eradication rate of 92.4% compared to a vancomycin plus aztreonam rate of 93.6% for all pathogens. The ceftaroline clinical cure rate was 93.1% in Staphylococcus aureus infections in the microbiologically evaluable population and 93.3% for MRSA infections. Treatment was well tolerated, with an adverse events profile similar between the two treatment arms. Based on the results Forest plans to continue with the development of ceftaroline.

June 23, 2008

Avontec issued positive results from a phase I study of AVT-02 UE for the treatment of inflammatory skin diseases. This randomized, double-blind, placebo-controlled study enrolled 20 healthy male subjects. The subjects received AVT-02 UE ointment applied topically twice a day for 28 days. The tolerability of AVT-02 UE was rated separately by the investigator and the subject on a five point scale ranging from 1=very good to 5=very poor. At all visits, the tolerability at each test area of both active and placebo was rated as either "good" or "very good". No substantial changes in laboratory values or skin physiology parameters, including transepidermal water loss, corneometry, sebumetry and measurement of the melanin and hemoglobin content, were found throughout the study. Pharmacokinetic assessment revealed that treatment with AVT-02 UE ointment was not associated with measurable blood concentrations of the active ingredient. Treatment was well tolerated, with no serious adverse events. A phase IIa trial is currently underway for the potential treatment of psoriasis.

January 21, 2008

Amgen and Wyeth issued positive results from a phase III trial of Enbrel for the treatment of moderate to severe plaque psoriasis in children and adolescents. This trial enrolled two hundred and eleven pediatric subjects with psoriasis who were initially randomized to receive twelve once-weekly weight-based doses of Enbrel (0.8 mg/kg up to the intended dose of 50 mg) or placebo. After this double-blind portion, two hundred and eight subjects entered a twenty four-week period of open-label Enbrel treatment once-weekly. At week thirty six, one hundred and thirty eight subjects were re-randomized to receive either Enbrel or placebo, to investigate withdrawal and re-treatment. The primary endpoint was at least a 75% improvement on the Psoriasis Area and Severity Index (PASI 75) at week twelve. After twelve weeks, the conclusion of the double-blind, placebo-controlled portion of the study, 57% of the subjects treated with Enbrel achieved PASI 75, compared with 11% of those treated with placebo (p less than 0.001). After twenty four weeks of open-label treatment, during which all subjects received Enbrel, PASI 75 was achieved by 68% of the subjects initially treated with Enbrel from the start of the study and 65% of those who initially received placebo. At the conclusion of the open-label treatment period (week thirty six), one hundred and thirty eight subjects were re-randomized to receive either Enbrel or placebo. During this period, the subjects who lost PASI 75 were re-treated. No rebounds or changes in the type of psoriasis were reported. Based on the results, Amgen filed a sBLA with the FDA for the use of Enbrel in this population.

CollaGenex reported positive results from a phase IV trial of Oracea for the treatment of rosacea. This prospectively randomized, double-blinded, placebo-controlled clinical study enrolled ninety one subjects in the US. The subjects were treated once daily with either doxycycline (100 mg) or Oracea (40 mg doxycycline, controlled release), both as an adjunct to topical MetroGel 1%, for sixteen weeks. Efficacy and adverse events were evaluated at baseline and at weeks four, eight, twelve and sixteen. The objective of the study was to demonstrate that increasing the dose of doxycycline above the anti-inflammatory levels provided by Oracea does not provide any additional benefit but significantly adds to the adverse event profile. The primary endpoint was the mean change in total inflammatory lesion count from baseline to the week sixteen. The subjects in the Oracea arm had an average of 19.8 inflammatory lesions at baseline and experienced a decrease in lesion count of 12.5 lesions, compared with 17.7 lesions at baseline and a decrease of 12.2 lesions in the doxycycline, 100 mg group. In addition, there were no differences observed between the treatment groups regarding the secondary endpoints of Investigators Global Assessment and Clinician's Erythema Assessment with (p-values of 0.86 and 0.50, respectively). A clear difference in the incidence of adverse events, primarily gastrointestinal reactions, was observed between the treatment groups. Nausea, vomiting, diarrhea and stomach discomfort were observed in 26% of subjects administered 100 mg of doxycycline versus only 5% in the Oracea group. Oracea is currently under investigation for the treatment of periodontal disease.

September 17, 2007

Moberg Derma issued positive results from a phase II trial of K301 for the treatment of seborrheic dermatitis of the scalp. This randomized, double-blind, placebo-controlled study enrolled 98 subjects in Sweden. Subjects received placebo or one of two doses of K301 applied topically once daily for the first four weeks followed by four weeks of maintenance treatment. The primary endpoint was the degree of erythema and desquamation after four weeks. Results demonstrated that 76% of subjects who received the most efficacious formulation of K301 had a positive response to the treatment, compared to 40% for placebo. Treatment was well tolerated, with adverse events similar to placebo. Based on the results Moberg plans to initiate a phase III trial of K301 in Q4 of 2007.

July 23, 2007

Arpida reported positive results from a phase III trial, dubbed ASSIST-2 (Arpida Skin and Skin Structure Infection STudies), of iclaprim for the treatment of complicated skin and skin structure infections (cSSSI). This randomized, blinded, comparator controlled trial enrolled 494 subjects internationally. The trial was designed to compare intravenous iclaprim to linezolid (standard of care). The primary efficacy endpoint, statistical non-inferiority in the clinical cure rate at the Test-Of-Cure (TOC) visit, was achieved. The overall clinical cure rates were 84.9% and 87.2% for iclaprim and linezolid, respectively. The microbiological eradication rates for methicillin-susceptible S. aureus (MSSA) bacteremia were 83.5% and 84.7% for iclaprim and linezolid respectively and for methicillin-resistant strains (MRSA) 77.0% and 80.0%, respectively. The incidence of drug-related adverse events was higher in the linezolid arm compared to the iclaprim arm (34.6% versus 27.9%, respectively). Based on positive phase III results, Arpida plans to file a NDA with the FDA later in 2007.

July 16, 2007

Theravance announced positive results from a phase II trial of TD-1792 for the treatment of complicated skin and skin structure infections (cSSSI) caused by Gram-positive bacteria. This randomized, double-blind, active-controlled trial enrolled 197 subjects who received either 2 mg/kg TD-1792 dosed once daily or vancomycin (standard of care) dosed 1 g twice daily for up to 14 days. Aztreonam and/or metronidazole were added for Gram-negative or anaerobic coverage. The primary endpoint, non-inferiority in clinical cure rates as measured at days 7 and 14, was achieved. In the clinically evaluable population, the clinical cure rates were 91.7% for the subjects treated with TD-1792 and 90.7% for the subjects treated with vancomycin. The clinical cure rates for the subjects with methicillin-resistant Staphylococcus aureus (MRSA) infections were 94.7% for the TD-1792 arm and 91.9% in the vancomycin arm. In the all-treated population, the clinical cure rates were 80.6% and 82.8% in the TD-1792 and vancomycin groups, respectively. Of the microbiologically evaluable subjects, the clinical cure rates for TD-1792 and vancomycin were 93.7% and 92.1%, respectively. Based on the results, Theravance plans to evaluate higher doses of TD-1792 in further trials.

July 2, 2007

Replidyne released positive results from three phase I trials of REP8839 for the treatment of bacterial skin and wound infections. A total of 400 subjects were enrolled in the trials. In the first study, subjects received repeated daily applications of REP8839 at three concentrations (1%, 2% and 4%), on intact and abraded skin. Safety, tolerability and skin irritancy were tested. Irritancy scores comparable to placebo were recorded for all REP8839 exposed test subjects. In the second study, subjects received repeated daily application of REP8839 on a larger surface area of intact and abraded skin. In addition to safety, tolerability and dermal irritancy, systemic exposure was evaluated. In all subjects, REP8839 was associated with low systemic exposure and low skin irritancy. In the third study, a 2% formulation of REP8839 was evaluated for its’ ability to cause long-term sensitization and irritancy. No sensitization reactions were recorded and low irritancy potential was observed. No serious adverse events occurred in any of the three trials. Based on the results, Replidyne plans to initiate a phase II trial of REP8839 for the treatment of impetigo in pediatrics by the end of 2007.

February 26, 2007

Basilea issued positive results from a phase III trial of alitretinoin for the treatment of hand dermatitis. This randomized, double-blind trial enrolled 1,032 subjects whose dermatitis was unresponsive to potent topical steroids. Subjects received a once daily dose of alitretinoin at 10 mg or 30 mg or placebo for a 24 week treatment duration. The primary endpoint was the proportion of subjects with clear or almost clear hands as defined by the Physicians Global Assessment. Treatment was well tolerated with all adverse events dose dependent and reversible. Alitretinoin was statistically superior to placebo at both the high and low dose. In the 30 mg group 48% of subjects (p less than 0.001) and in the 10 mg group 28% of the subjects (p=0.004) reached the primary endpoint compared to a 17% response rate in the placebo group. These results are going to be used as part of a NDA filing later in 2007.

January 29, 2007

Barrier reported positive results from a phase IIa trial of Hivenyl for the treatment of atopic dermatitis. This multi-center, double-blind, placebo-controlled trial enrolled 44 subjects in Belgium and the Czech Republic. After undergoing a one-week lead-in period, subjects were randomized to receive oral Hivenyl 60 mg twice daily or placebo for one week. All subjects were also treated with a topical corticosteroid and an emollient daily throughout the study. Treatment was well tolerated with no signs of sedation. Of the 23 subjects in the Hivenyl treatment group, 9 reported either a marked improvement or an almost complete to complete improvement of their itch symptoms versus none of the 21 subjects in the placebo group (p < 0.01). Additionally, in these nine subjects the overall clinical severity score, as measured by the Eczema Area and Severity Index (EASI), showed a reduction of the atopic dermatitis lesions. Based on these results, Barrier plans to move forward with the development of Hivenyl.

January 15, 2007

Basilea reported positive results from a phase III trial, dubbed STRAUSS II, of ceftobiprole for the treatment of complicated skin and skin structure infections. This trial enrolled 828 subjects who were randomized 2:1 to receive ceftobiprole or the combination of ceftazidime plus vancomycin. Treatment was well tolerated, with adverse events comparable between the two groups. The primary endpoint, statistical non-inferiority between the two treatment groups, was achieved with 91% of the subjects cured with ceftobiprole cured versus 90% cured with the combination therapy. Of the subjects with diabetic foot infection, the clinical cure rate for ceftobiprole was 86% versus 82% for the comparator. Over 20% of the subjects had a methicillin-resistant Staphylococcus aureus (MRSA) infection. The clinical cure rate for ceftobiprole in MRSA subjects was 91% compared to 86% for the combination group. One third of the population had an infection involving a gram negative pathogen. The cure rate between the two treatment groups was the same at 84%. Based on these results, Basilea plans the first regulatory filing for ceftobiprole to take place in 2007.

December 4, 2006

Arpida reported positive results from a phase III trial, dubbed ASSIST-1, of iclaprim for the treatment of skin and skin structure infections (cSSSI). The trial was designed to compare iclaprim to linezolid, a previously approved treatment. This international, randomized, double-blind trial enrolled 497 subjects with cSSSI. Subjects were assigned (1:1) to receive intravenous iclaprim (0.8 mg/kg) or intravenous linezolid (600mg) for 10 to 14 days and were evaluated during treatment. The Test-Of-Cure visit took place 7-14 days after the end of treatment. Treatment was well tolerated with no serious adverse events reported. The primary endpoint, statistical non-inferiority in the clinical cure rate at the Test-Of-Cure (TOC) visit, was reached. The overall clinical cure rates for the Intent-To-Treat population of 497 subjects, were 85.5% and 91.9% for iclaprim and linezolid, respectively. For the clinically evaluable subjects, the cure rates were 93.8% and 99.1% for iclaprim and linezolid, respectively. A similar phase III trial, ASSIST-2, is currently underway. Arpida plans to file a NDA with the FDA in 2007.

Dynavax announced positive results from a phase III trial of Heplisav for the treatment of Hepatitis B. This trial enrolled 400 seronegative subjects who received three doses of the Heplisav vaccine or three doses of Engerix-B, an approved Hepatitis B vaccine. The primary endpoint of the trial was seroprotection four weeks after the third immunization. Results revealed that, after three doses, Heplisav provided seroprotection to 100% of subjects while Engerix-B provided seroprotection to 73.1% (p < 0.0001). The greatest deviation in seroprotection was observed in the subjects aged 56 to 70 years where Heplisav provided 100% seroprotection and Engerix-B provided 56.1% seroprotection. Dynavax plans to initiate phase III trials to investigate a two dose regimen of Heplisav versus Engerix-B by late 2006 to early 2007.

October 9, 2006

Basilea and Johnson & Johnson reported positive results from a phase III trial of ceftobiprole for the treatment of complicated skin and skin structure infections (cSSSI) due to Gram-positive bacteria. The trial was designed to compare the clinical cure rates of ceftobiprole versus vancomycin, a commonly used antibiotic. This multi-center, randomized, double-blind trial enrolled 784 subjects with cSSSI caused by gram positive bacteria. Subjects received ceftobiprole (500 mg IV q 12hr) or vancomycin (1gm q IV 12hr) and were observed 7-14 days after treatment for clinical cure results. Safety and tolerability data revealed that treatment was well tolerated. The most commonly reported adverse events included rashes, nausea and taste disturbances. Efficacy data revealed that cure rates in the ceftobiprole-treated and vancomycin-treated groups were 93.3% and 93.5% respectively.

Connetics issued positive results from a second phase III trial of Extina foam for the treatment of seborrheic dermatitis. This double-blinded, active- and placebo-controlled trial enrolled 1,162 patients at 24 centers in the United States. The trial met the primary endpoint of demonstrating that Extina is superior to placebo foam. This was measured using the Investigator's Static Global Assessment (ISGA), which for this trial was an evaluation of the severity of seborrheic dermatitis determined by the clinically relevant signs of the disease. Efficacy results showed a statistically significant response difference with a 56% response rate for Extina and a 42% response rate for placebo foam (p=0.0001). Based on these results Connetics planned to resubmit a NDA to the FDA by the end of 2006.

Acambis announced results from a phase II trial of MVA3000, an investigational smallpox vaccine for subjects with whom traditional vaccination is contraindicated. Safety data yielded a positive tolerability profile, with only mild adverse events reported. These events included injection site reactions, headache, fatigue, malaise and muscle ache. Efficacy data yielded positive results as well. Of the vaccine naïve subjects who received the highest dose of MVA3000, 75% seroconverted (a 4-fold or greater increase in vaccinia virus neutralizing antibodies) after two doses. Of the previously vaccinated subjects who received the highest dose of MVA3000, 88% seroconverted after two doses. This randomized, double-blind, placebo-controlled study enrolled 590 healthy subjects; 361 of whom had never received a smallpox vaccine (vaccine naïve) and 229 of whom had previously been vaccinated against smallpox. Based on these results, additional development of MVA3000 was planned.

Cerexa announced positive top-line results of a phase II trial of ceftaroline, for the treatment of complicated skin and skin structure infections (cSSSI). Efficacy data yielded a 96.8% clinical cure rate for the subjects treated with ceftaroline, versus an 88.9% cure rate for those treated with standard therapy. The microbiological response rate for the ceftaroline group was 95.2%, compared to 85.7% for the standard therapy group. Finally, ceftaroline demonstrated activity against gram-positive and gram-negative organisms isolated from patients in the study, including 100% of MRSA isolates inhibited at 0.5 mg/L or less. Safety data revealed a positive adverse event profile, with headache the most commonly reported event; control treatment yielded incidence of interstitial nephritis-related renal failure and "Red Man" syndrome. Subjects were treated with ceftaroline or standard therapy of vancomycin, with or without adjunctive aztreonam.

Cytrx announced positive preliminary results of a phase I trial of DP6-001, their investigational HIV DNA + protein vaccine. Preliminary trial data yielded a generally positive overall tolerability profile, and bioactivity measures indicated that the vaccine elicited both HIV-specific T-cell and antibody immune responses. Low grade adverse events included pain and redness at the injection site, mild body ache and low grade fever; there was some evidence that adverse events were dose proportional. This study enrolled 34 healthy volunteers, who received either a 3-dose low dose subcutaneous or intramuscular regimen of the drug, or a 3-dose high-dose intramuscular regimen of the drug. Additional results from the study were expected later in 2006.

Trial data met their primary safety endpoint, with no serious adverse events reported and positive local and systemic adverse event profiles. Pharmacokinetic data did not indicate systemic exposure 48 hours post treatment in the highest dosing group. This multicenter, 4-arm, randomized, open-label, parallel- group comparison study enrolled 28 patients with plaque psoriasis; subjects received one of three dose concentrations of CTA018 (1, 3, or 10 mcg/g) or vehicle cream, applied to 5% of the body surface daily for 13 days, with a observational follow-up 7 days after treatment. Based on these results, the company announced plans to initiate a phase II trial of the drug in Q4 2005.

Isolagen announced positive results of a phase III trial of their autologous fibroblast transplant therapy, dubbed the Isolagen Process, for the treatment of dermal contour deformities. Results from the parallel-arm study met three of four primary endpoints, producing significant improvements in appearance of contour deformities on both patient and physician visual assessment scales in one arm, but only statistical improvement in patient assessment in the second arm. Significant efficacy variance was noted between investigative sites (range of improvement: 7.6%-73.3%), based primarily on differences in injection technique. This randomized, double blind, placebo-controlled parallel arm study enrolled two study cohorts of 100 patients each across 5 US sites. Based on these results, Isolagen announced that they planned to initiate an additional 100 patient study of the drug with expended training regarding injection technique. This additional trial delays the projected BLA filing date until 2006.

Isotechnika reported positive interim results of their phase III SPIRIT trial of ISA247 for the treatment of psoriasis. Blinded, combined data from all treatment groups from the first 12 weeks of the trial (n=369 patients) yielded a mean reduction in Psoriasis Area and Severity Index (PASI) score of 38%, indicating potential efficacy. The data also indicated a positive safety profile, with the highest variance in serum creatinine levels in any treatment group being 5.6%, a value considered within the normal physiogical range. Less than 2% of subjects in any dosing group withdrew from the study after 12 weeks due to changes in kidney function. This randomized, double-blind study enrolled 453 patients with severe plaque psoriasis across 32 sites in Canada. Subjects received one of 3 doses of ISA247 (0.2 mg/kg, 0.3 mg/kg and 0.4 mg/kg) or placebo twice daily, with subjects receiving placebo switching to the middle dosing regimen after the first 12 weeks of the 24 week study.

July 25, 2005

Foamix has reported positive results of a phase II/III study of PerFoam (permethrin 1%), their investigational topical foam for the treatment of head lice. Result from the study indicated that the drug killed head lice in 54 of 56 subjects (96.4%) and completely removed lice eggs in 60% of subjects; these results suggest potential of PerFoam in overcoming resistance to shampoo or cream/lotion rinse formulations of permethrin. Safety and tolerability data were positive and yielded possible evidence of superiority to currently approved formulations of permethrin, with no incidence of skin or eye irritation. This open-label study enrolled 56 pediatric patients with head lice at the Laniado Medical Center in Netanya, Israel, under the direction of Dr Avner Shemer. Subjects received initial, 10- minute application of PerFoam at baseline and again at day 10.

July 18, 2005

Critical Therapeutics has issued negative results of a phase II trial of Zyflo (zileuton) for the treatment of inflammatory facial acne. Zyflo is currently approved as a treatment for asthma. Results from the study indicated that the drug failed to meet its primary efficacy endpoint: subjects receiving Zyflo experienced a mean reduction in inflammatory lesion count of 11.5 (33.5%), compared to a reduction of 9.5 lesions (26.9%) for placebo, but the difference between these values was not significant (p=0.384). Mean total lesion count, a secondary efficacy measure, showed a positive trend, but also failed to achieve significance (25.3 fewer lesions for Zyflo vs. 16.4 fewer for placebo, p=0.085). A subset of patients with more severe acne yielded some positive results: absolute mean inflammatory lesion count showed a non- significant positive trend compared to placebo (16.2 vs. 11.7; p=0.063), mean inflammatory lesion count decreased significantly (41.6% vs. 26.2%; p=0.025), and trends towards rapid onset of activity were noted at weeks 4 (p=0.078) and 8 (p=0.057). This randomized, double-blind, placebo-controlled study enrolled 101 patients with moderate to severe inflammatory facial acne across 12 US sites. Subjects were randomized to receive zileuton 600 mg (n=52) or placebo (n=49) four times daily for 12 weeks. The company indicated that they were continuing to interpret data from the study, and expected additional guidance in August 2005.

Vicuron reported positive results from a phase II trial investigating dalbavancin, a glycopeptide antibiotic for the treatment of skin and soft tissue infections (SSTIs). Results showed higher clinical and microbiological response rates compared to a variety of standard care regimens. Data demonstrated higher clinical (94.1%) and microbiological (72.7%) response rates for deep SSTIs with two doses versus a single dose of dalbavancin (61.5% clinical; 27.3% microbiological) or control (76.2% clinical; 64.3% microbiological). The control arm consisted of investigator-specified standard of care such as treatment with one of the antibiotics, clindamycin, ceftriaxone, vancomycin or cefazolin. The randomized, controlled study enrolled 62 subjects with complicated SSTIs. Dalbavancin was well tolerated and adverse events were infrequent. Results were presented at the European Congress of Clinical Microbiology and Infectious Diseases.

Atrix Laboratories has reported positive results from the first phase III trial with Atrisone, for the treatment of acne. Atrisone (dapsone 5%) is a twice-daily drug administered via Atrix's SMP topical drug delivery technology. Based on the 500 subject, double-blind, vehicle-controlled study, Atrisone was found to be clinically superior to vehicle (SMP alone) on all four primary and both secondary endpoints. Primary endpoints included reduction in inflammatory and non-inflammatory lesion counts, reduction in overall lesion count and improvement in overall appearance. The secondary endpoints of the trial were lesion count change from baseline and percent change from baseline. Atrix plans to move forward with a second phase III trial with Atrisone.

Positive results were reported from a phase II trial of topical alicaforsen (ISIS 2302) in subjects with mild to moderate plaque psoriasis. The double-masked trial, which included 31 subjects, compared 4% topical alicaforsen cream to placebo. Fifteen subjects in the trial applied treatment once per day, while 16 applied twice per day. Results showed that treatment with alicaforsen resulted in statistically significant improvement in Investigators Global Response Score (IGRS) at week four and a positive trend toward improvement at week eight. Furthermore, alicaforsen produced a 31% improvement from baseline in terms of plaque induration at both four and eight weeks. Alicaforsen is being developed by Isis Pharmaceuticals.

Data from a pooled analysis of two phase III trials indicates that Xanelim (efalizumab) produces an early clinical improvement in subjects with moderate-to-severe psoriasis. In the two trials, 1,095 subjects received weekly subcutaneous doses of 1 mg/kg Xanelim, 2 mg/kg Xanelim or placebo. At 12 weeks, mean PASI score improvements were 14% for the 1 mg/kg Xanelim group and 13% for the 2 mg/kg group, compared to 8% for placebo-treated subjects. Furthermore, after 12 weeks, 29% of subjects treated with 1 mg/kg Xanelim and 28% of those treated with 2 mg/kg achieved PASI score improvement of 75% or greater, versus 3.4% of those receiving placebo. Xanelim is being developed by Genentech and Xoma.

Phase III trial results suggest that Novartis' Elidel (pimecrolimus) cream 1% is more effective than a conventional treatment in reducing the incidence of disease flares. The 12-month, multicenter, double-blind study included 713 pediatric eczema subjects ages two to 17 years. The trial compared a long-term Elidel treatment regimen with a current conventional therapy regimen. Subjects applied either treatment at the earliest signs or symptoms of the disease. Both groups also used topical corticosteroids to treat any severe flares. At both six and 12 months, results showed that Elidel significantly reduced flare incidence compared to the conventional therapy. Additionally, 57% of subjects treated with Elidel had no flares that required corticosteroid treatment, compared to 32% in the control group.

Positive phase I results were reported from testing of 5G1.1 in 13 subjects with dermatomyositis. The drug, a humanized monoclonal antibody C5 complement inhibitor in an intravenous injection formulation, appeared to be well tolerated and to improve skin rash. Treatment was given once a week for five weeks, then every two weeks for up to two months. Though safety was the primary study aim, measurements of skin rash and muscle strength were also recorded, showing consistent trends in improvement with drug administration. Few adverse events were observed, and those seen were comparable for treatment and placebo groups. 5G1.1 is being developed by Alexion Pharmaceuticals.

Preliminary phase II trial results indicate that Micrologix Biotech's MBI 594AN produced a 32% reduction in total acne lesion counts (inflammatory plus non-inflammatory lesions) compared to a 14% reduction for placebo. The randomized, double-blind trial enrolled 75 acne subjects who received twice-daily dosing with either one of two formulations of MBI 594AN (2.5% and 5%) or the product's alcohol-based vehicle alone. Subjects treated with MBI 594AN showed a 39% reduction in inflammatory acne lesion counts compared with 21% for the placebo group. In terms of non-inflammatory acne, MBI 594AN treated subjects experienced a 25% improvement in lesion reduction, compared to 10% for placebo treated subjects.
