Elcelyx Therapeutics reported results of
a 12-week phase IIb study of NewMet, a
delayed-release formulation of metformin
for the treatment of patients with type 2
diabetes. The randomized, 240-patient, multicenter,
double-blind, dose-finding trial evaluated
NewMet once-daily doses of 1000mg,
800mg and 600mg compared to placebo.
There also were two unblinded reference
arms with Glucophage XR dosed once-daily
at 1000mg and 2000mg. All NewMet arms
showed efficacy comparable to or greater
than 1000mg of Glucophage XR. The NewMet
1000mg dose was approximately 50% more
effective than 1000mg of Glucophage XR and
approximately 70% as effective as 2000mg of
Glucophage XR. A dose response trend was
observed across the three NewMet doses,
indicating higher doses of NewMet may
provide greater efficacy. All doses of NewMet
and Glucophage XR prevented the rise in
HbA1c seen with placebo due to washout
of previous anti-diabetic medications. All
doses of NewMet and Glucophage XR were
well-tolerated and there were no meaningful
weight changes observed.

GlaxoSmithKline issued results from a phase III trial of albiglutide versus sitagliptin for the treatment of renal impairment. This double-blind, active-controlled, parallel-group, multicenter study, Harmony 8, enrolled patients with type 2 diabetes. Subjects received recommended doses of either albiglutide of sitagliptin for 52 weeks. At the 26-week primary endpoint, albiglutide showed clinically and statistically significant reductions in HbA1c from baseline (8.08% for albiglutide and 8.22% for sitagliptin) and superiority versus sitagliptin (reduction of 0.83% vs 0.52%; p<0.0001 for non-inferiority and p=0.0003 for superiority). At the primary endpoint, weight loss was significantly greater in the albiglutide group than the sitagliptin group (-0.79kg vs -0.19kg; p=0.0281). During the full 52-week treatment period, albiglutide was generally well tolerated. The most frequent adverse events were diarrhea (albiglutide 10%, sitagliptin 6.5%), nausea (4.8%, 3.3%) and vomiting (1.6%, 1.2%). With these data now available, GSK intends to commence global regulatory submissions for its investigational glucagon-like peptide-1 (GLP-1) receptor agonist albiglutide for the treatment of type 2 diabetes in early 2013.

Adocia issued results from a phase I trial of HinsBet, their formulation of a fast-acting human insulin. This double blind study enrolled 12 healthy subjects who received HinsBet, NovoLog, a fast-acting insulin analog or Actrapid, a regular human insulin. On the primary endpoint of safety, HinsBet showed identical results to the control products, giving excellent local tolerance and absence of pain at the site of injection. The onset of action of HinsBet was as short as NovoLogs and shorter than that of Actrapid. This was demonstrated by insulin profile and glucose infusion rate profile. In addition, the inter-patient variability on glycemic control with HinsBet was statistically lower than with NovoLog or Actrapid.

SemBioSys Genetics issued positive results from a phase I trial of SBS-1000, a safflower seed derived human insulin product, for the treatment of diabetes. This single administration, double blind trial, three-way cross-over study enrolled 23 healthy subjects. The subjects were administered the same dose of SBS-1000, Humulin R and Humulin S (recombinant human insulin). Bioequivalence was measured for the following primary endpoints: total insulin exposure, calculated from the measured blood levels for insulin for eight hours post-injection; maximum concentration of insulin; total glucose infused over eight hours and maximum glucose infusion rate. Both SBS-1000 and Humulin R were bioequivalent to Humulin S with respect to total insulin exposure, maximum concentration of insulin and total glucose infused. Neither SBS-1000 nor Humulin R was bioequivalent to Humulin S with respect to the maximum glucose infusion rate. SBS-1000 was well tolerated.

Johnson and Johnson reported positive results from a phase III trial of ceftobiprole for the treatment of diabetic foot infections. This multi-center, double-blind trial enrolled 257 subjects with diabetic foot infections without concomitant osteomyelitis. The subjects were randomized to receive either 500 mg of ceftobiprole administered intravenously every eight hours or 1g of vancomycin administered intravenously every 12 hours plus 1g of ceftazidime administered intravenously every eight hours. Ceftobiprole was shown to clinically cure 86.2% of the infections, including those caused by methicillin-resistant Staphylococcus aureus, compared to an 81.8% cure rate seen with the combination treatment. Treatment was well tolerated, with an adverse event profile similar between the two groups. An NDA for ceftobiprole is currently under review by the FDA.

Atherogenics reported positive results from a phase III trial of AGI-1067 for the treatment of diabetes and coronary heart disease. This trial, dubbed ARISE (Aggressive Reduction of Inflammation Stops Events), enrolled over 6,000 subjects internationally. Subjects received AGI-1067 or placebo both in conjunction with standard of care. After 12 months of treatment, AGI-1067 significantly lowered levels of glycated hemoglobin A1c, a measure of glycemic control, in subjects with and without diabetes. In addition, the data showed a 59% reduction in the development of new onset diabetes in subjects with impaired fasting glucose (p < 0.0001). In the subjects with diabetes, AGI-1067 showed a 22% reduction in hard cardiovascular events of cardiovascular death, cardiac arrest, myocardial infarction and stroke (p=0.062). Additional phase III trials are currently underway.

Genaera reported positive interim results from a phase I trial of trodusquemine for the treatment of obesity. This double-blind, randomized, placebo-controlled, single ascending dose trial had enrolled 28 healthy, obese subjects to date. Pharmacokinetic data showed a predictable pattern with minimal subject-to-subject variability and linearity across the range of doses studied. Treatment has been well tolerated, with no reported adverse events. Genaera is continuing this trial in order to determine the maximum tolerated dose and establish dose-limiting toxicity and proof-of-concept. Full results are expected by the end of 2007.
MicroDose and QDose issued positive results from a phase I trial of an inhaled insulin product for the treatment of diabetes. This randomized, crossover, open-label glucose clamp study enrolled 14 healthy male subjects in the US. The trial was designed to confirm the high relative bioavailability of the QDose insulin formulation and to demonstrate the product's dose titration capability. Results showed peak levels of insulin activity were achieved more quickly following the inhaled insulin than those from the subcutaneous insulin injection. The relative bioavailability of inhaled insulin was approximately 18% during the 3 hour period following dosing. Based on the results the companies plan to advance the product into additional trials.
Phosphagenics announced positive results from a phase Ib trial of TPM-02 transdermal insulin for the treatment of diabetes. This efficacy and safety trial enrolled 45 healthy subjects at the Royal Adelaide Hospital in South Australia. Subjects received two TPM/Insulin dose formulations. Efficacy was assessed by blood glucose, endogenous insulin and C-peptide levels. The formulation safely penetrated through the skin, delivered insulin into the bloodstream over a sustained period of time and lowered blood glucose without causing adverse reactions. Based on the results, Phosphagenics plans to initiate a phase II trial before the end of the year.
March 12, 2007
Transition released positive results from two phase IIa trials of E1-INT for the treatment of type I and type II diabetes. The first trial enrolled 32 subjects with type II diabetes with HbA1c baseline levels of equal to or greater than 7%. Subjects received EI-INT or placebo for 28 days. The HbA1c levels decreased by an average of 0.97% (p=0.0273) and 1.12% (p=0.0273) in months 2 and 3 post-treatment, respectively. Fasting blood glucose levels were reduced by an average of 45 mg/dL (p=0.0234) versus an increase of 16 mg/dL in the placebo group and glucose tolerance improved in months 1, 2 (p=0.0098) and 3 (p=0.0020) post-treatment. The second trial enrolled 20 subjects with type I diabetes who also received EI-INT or placebo for 28 days. Of the subjects on therapy, 54% decreased their insulin usage by an average of 37% in months 1, 2 or 3 post-treatment. There were no responders in the placebo group. Based on the results, Transition plans to accelerate the development of E1-INT into larger phase II trials.
December 4, 2006
Generex reported positive results from a phase II trial of Oral-lyn for the treatment of type 1 diabetes. This trial was designed to compare the effects of two forms of prandial (mealtime) insulin, Oral-lyn and subcutaneous regular insulin, in subjects with type 1 diabetes mellitus maintained on basal isophane insulin (NPH). The trial enrolled 25 subjects, 11 of who received twice daily injections of NPH and three pre-meal injections of regular insulin and 14 of who received twice daily injections of NPH and three split-dose applications of Oral-lyn. Following a stabilization phase, a 99 day comparison phase was conducted, with fructosamine and glycated hemoglobin (HbA1c) determined, on average, every 14 days. Results revealed that both Oral-lyn and mealtime injections of regular insulin achieved near normalization of metabolic control parameters as reflected by continuous improvement in fructosamine and HbA1c concentrations. These results will provide the format for a phase III study in 300 subjects slated to begin in early 2007.
November 27, 2006
FibroGen issued positive results from a phase Ib trial of FG-3019 for the treatment of type 1 or type 2 diabetes and microalbuminuria. This open-label, multiple dose, sequential-group, dose-escalation trial enrolled 24 subjects who received 3 or 10 mg/kg of FG-3019 administered as 2-hour intravenous infusions once every 2 weeks (Days 0, 14, 28 and 42) for a total of 4 doses over 2 months. At conclusion of the study, 14 subjects received doses of 3 mg/kg, and 10 patients received doses of 10 mg/kg. The trial was designed to evaluate safety, tolerability and pharmacokinetic profiles. Treatment was well tolerated with no drug related serious adverse events reported. No dose limiting toxicities were observed. FG-3019 was saturable, and accumulation of FG-3019 in the bloodstream was limited during the dosing interval. In addition, the urinary albumin to creatinine ratio (ACR) significantly decreased from baseline as compared to Day 56. The mean change in ACR was a reduction of 27 mg/g (p=0.027) from a baseline average of 61 mg/g and urinary ACR decreased by 50%. Based on these results FibroGen plans to move development of FG-3019 forward.
November 6, 2006
Emisphere released positive results from a phase II trial of eligen oral insulin for the treatment of type II diabetes. This trial was designed as a four arm study consisting of three doses of oral insulin (10mg QID, 5 mg QID and 10 mg BID) and placebo. Each arm held 35 subjects. Primary endpoints included safety and efficacy, measured by changes in Hemoglobin A1c (HbA1c) over 90 days. Treatment was well tolerated with no serious adverse events reported. Statistical significance was reached in the total number of subjects achieving a hemoglobin A1c (HbA1c) decrease of more than 1.1% in the arm receiving the 10 mg QID dose of oral insulin versus placebo (p=0.0368). Although a dose response relationship was observed in the other treatment arms, statistical significance was not reached when compared to placebo. Based on the results, Emisphere plans to continue with the development of eligen oral insulin.
September 25, 2006
MannKind announced positive results from a phase III trial of Technosphere inhaled insulin for the treatment of type II diabetes. This trial enrolled 308 subjects who were randomized to the mealtime use of either Technosphere insulin (n=150) or injected rapid acting insulin analog (RAA), (n=158), plus insulin glargine as basal insulin. Subjects were than followed for 24 weeks while individual adjustments to therapy were made. Efficacy results revealed that both treatment groups achieved a statistically significant improvement in HbA1c (average blood glucose) levels, with 1.05% of the Technosphere group and 1.30% of the RAA group achieving this. Significantly fewer subjects in the Technosphere group experienced hypoglycemia than in the RAA treated group. In addition those subjects in the Technosphere arm achieved an average weight loss of 0.76 kg versus an average weight gain of 0.23 kg in the RAA arm (p=0.0007). MannKind currently has several phase III trials underway.
September 5, 2006
Diamyd Medical released positive results from a phase II trial of Diamyd for the treatment of type I diabetes in the pediatric population. This trial enrolled 70 children and adolescents who received two 20 mg injections of Diamyd, or placebo, one at day 1and one at day 30. Safety profiles were positive with no treatment related adverse events reported. Efficacy data taken 15 months after the initial treatment demonstrated that the subjects who received Diamyd produced approximately twice as much meal stimulated insulin (as measured by C-peptide) when compared to the placebo group (p ˜ 0.01). Additionally there were no significant differences in fasting C-peptide levels between the two groups. Phase II trials are ongoing for the treatment of types I and II diabetes.
Phosphogenics reported positive interim results from a phase I trial of TPM-02, a transdermal insulin gel, for the treatment of diabetes. This double-blind, placebo controlled trial enrolled 20 healthy male subjects. Subjects were fasted overnight, than randomized to receive a single dose of TPM-02 or a placebo gel, applied directly onto the skin. Subjects were then to be observed for 48 hours to assess the primary endpoint of safety as well as secondary endpoints of effect on blood glucose and insulin levels. No serious adverse events were reported. After one application TPM-02 was shown to safely penetrate the skin and be delivered into the bloodstream over a continuous period of time. Additionally, the drug was able to significantly lower blood glucose levels. Based on these results Phosphogenics planned to move TPM-02 forward into phase II development.

Isis Pharmaceuticals issued positive result of a phase II trial of ISIS 113715, for the treatment of type 2 diabetes. This 2-stage, randomized, double-blind, placebo-controlled study enrolled patients in 2 stages. In the first stage, 66 patients received escalating weekly doses of 100 mg, 200 mg, 400 mg or 600 mg or placebo for 6 weeks. In the second stage, 22 subjects received treatment with 200 mg of the drug or placebo for 3 months. Results from the first stage yielded no serious adverse events, no incidence of hypoglycemia, weight gain, or metabolic acidosis, and a dose dependent reduction in fasting blood glucose (-21mg/dl, p=0.05) and LDL cholesterol levels (-17 mg/dl, p=0.02) at the highest dose level. Results from the second stage that all subjects receiving the weekly 200 mg dose for 3 months experienced improvements in several measures of glucose control and cardiovascular health from baseline compared to placebo, including self monitored fasting blood glucose (-23 mg/dl vs. -5 mg/dl; p=0.03), fasting serum glucose (-24 mg/dl vs. +5 mg/dl; p=0.002), total cholesterol (-16 mg/dl vs. +20 mg/dl; p=0.002), and LDL cholesterol (-13 mg/dl, vs. +11 mg/dl; p=0.03). A non-significant improvement was noted in HbA1c levels (-1.10% vs. -0.86%; p>0.05).
Novocell has issued preliminary results of a phase I/II trial of their encapsulated human islet allografts, for the treatment of Type I diabetes. Data collected to date from the first two subjects receiving the transplants yielded preliminary evidence that the transplanted cells were functional, and there was no indication of autoimmune reactions or allograft rejection to date. Subjects received only transient low dose cyclosporine (50-100 ng/ml 12hr trough), and did not require long term immunosuppression regimens. This open-label proof-of-concept study is ongoing in San Antonio, Texas, under the direction of Dr. Sherwyn Schwartz and Dr. Paraic Mulgrew.
Sangamo BioSciences issued positive pooled results of a phase Ia and phase Ib trial of SB-509, for the treatment of diabetic neuropathy. Trial data indicated that single administrations of the drug were well tolerated, with no serious adverse events reported at doses predicted to be clinically relevant. The most common overall adverse events were injection site reactions. Preliminary anecdotal data were positive, and included reports of clinical improvement: all subjects receiving the drug in both trials showed a positive trend towards improvements in total neuropathy score (TNS; a composite score including neurologic exam, QST, electrophysiologic studies and neurologic symptoms), while the subjects receiving placebo showed TNS deterioration. The phase Ia dose-escalation study enrolled 12 subjects with mild to moderate disease, who received a single injection of one of 4 dose levels of the drug (1 mg, 5 mg, 15 mg and 30 mg) in one legs, with placebo administration in the other leg, with observational follow-up at 1, 2, 3 and 6 months post-treatment. In a phase Ib extension of this study, 11 subjects had been enrolled to date who received single injections of one of two doses of the drug (15 mg, n=3; or 30 mg, n=4) or placebo (n=4) in both legs. Based on these results, 18 additional patients were to receive treatment with either the highest dose regimen (30 mg per leg) of SB-509 or placebo in the phase Ib trial, with a phase II study slated to begin in the second half of 2006.
April 17, 2006
NeuroVax announced positive results of a clinical trial of NeuroVax for the treatment of multiple sclerosis (MS) at the AAN Annual Meeting. This open-label study enrolled 25 subjects, 17 of whom had not previously received NeuroVax. The untreated patient subset showed significantly lower levels of FOXP3+ regulatory T-cells (as measured by FOXP3+ mRNA (p=0.03) and protein expression (p=0.02)). Trial data indicated that NeuroVax significantly increased FOXP3 expression in 14 of 17 subjects, including levels of both FOXP3+ mRNA (p=0.01) and FOXP3 protein (p=0.02). Based on these results, the company confirmed plans to initiate a phase II trial of NeuroVax for the treatment of MS across sites in the US and Eastern Europe later in 2006; this study was designed to investigate the effect of the drug on MRI measures and relapse rates.
Sangamo announced positive results of a phase I trial of SB-509, for the treatment of diabetic neuropathy, at the 58th Annual Meeting of the American Academy of Neurology (AAN) in San Diego. Primary safety data were positive, with no serious adverse events reported and mild injection site reactions the only noted all-severity adverse events. Dose limiting toxicities were not observed. Single administrations of the drug produced improvements in severity of pain, numbness and neurological symptoms in roughly 50% of subjects. Additional preliminary efficacy was noted in neurologic exam scores and electrophysiological testing. This single blind, single-dose dose-escalation study enrolled 12 subjects with mild to moderate disease, who received intramuscular injections of the drug. Based on these results, the company announced plans to initiate a phase II trial of SB-509 in the second half of 2006.
Somaxon reported positive results of their first phase III trial of Silenor (doxepin HCl), for the treatment of chronic insomnia. The drug was shown to significantly reduce 8-hour Wake After Sleep Onset (WASO), with a mean improvement of 26 minutes for the low dose and 31 minutes for the high dose groups, vs. placebo (p<0.0001). Improvement in secondary measures was also noted: Total Sleep Time was 415 min. and 421 min. for the two Silenor doses (respectively), vs. 374 min. for placebo (p<0.0001); Latency to Persistent Sleep during the initial treatment period was 27 minutes for both doses, vs. 45 minutes for placebo (p=0.011, p=0.0018); these improvements were not maintained at subsequent timepoints (due in part to improvements in the placebo group). This randomized, double-blind, placebo-controlled, parallel-group, multi-center study enrolled 229 patients, who received one of two doses of the drug (3 mg or 6 mg) or placebo nightly for 35 days.
January 23, 2006
MannKind Corporation has announced positive results of a phase IIb trial of their inhaled Technosphere insulin drug candidate, for the treatment of diabetes. Trial data indicated that addition of high-dose Technosphere insulin produced a reduction in percent-HbA1c levels 0.79 higher than that achieved with placebo at 8 weeks (p=0.0002). Further, maximal post-prandial glucose excursions were 63% lower than placebo (peak excursion: 34 mg/dL; p<0.0001). Pulmonary function was unchanged between treatment groups through 12 weeks, and there was no incidence of weight change or severe hypoglycemia in patients receiving the drug. This dose-ranging study enrolled 227 patients, who received either Technosphere insulin (14, 28, 42 and 56 units) or placebo in addition to approved treatment with insulin glargine.
December 12, 2005
OSI Pharmaceuticals has announced positive results of a phase IIa trial of PSN9301, their investigational dipeptidyl peptidase-IV inhibitor for the treatment of type 2 diabetes. Mean 0-2 hour serum glucose area-under-curve (AUC, a measure of total absorption) was significantly reduced (range: 24% to 42%) in the three highest dosing groups, following drug administration and oral-glucose-tolerance-test after 13 days of treatment. The drug produced a non-significant reduction of 13% in mean 24-hour glucose levels. No incidence of hypoglycemia was noted. This randomized, double-blind, placebo-controlled study enrolled 51 patients with type 2 diabetes, who received one of four dose levels of the drug on one of two dosing regimens on an in-patient basis for 14 days. Based on these results, OSI announced plans to initiate a phase IIb trial of the drug in mid-2006.
September 19, 2005

Trial data demonstrated similar efficacy to a standard regimen of injected insulin, with 3 month mean A1c levels of 7.9 and 8.0, respectively. Safety and tolerability data also yielded evidence of non-inferiority. This randomized, open-label, non-inferiority crossover study enrolled 259 type I diabetics, who received pre-meal HIIP (n=133) or insulin injections (n=126), in addition to maintenance treatment with long-acting insulin glargine once daily, for 12 weeks.
August 29, 2005
Antares Pharma reported results from a clinical trial involving Medi-Jector Vision, a needle-free injector for the deliver of insulin lispro. Results showed no significant differences in several key pharmacokinetic (PK) and pharmacodynamic (PD) measures between Medi-Jector Vision and conventional needle injection methods. The open-labeled, two-period crossover study enrolled type I & II diabetic subjects who received a controlled meal and a 10U lispro insulin dose delivered by either the Medi-Jector Vision needle-free injector or a traditional syringe injection.. Changes in insulin levels and blood glucose levels were recorded over a 4-hour period and analyzed to determine Cmax, Tmax, and AUC. The study was conducted by Dr. Sherwyn L. Schwartz at the Diabetes and Glandular Disease Clinic of San Antonio, TX.
Arena Pharmaceuticals reported a follow-up assessment of echocardiograms (ECHOs) from phase IIa trial results investigating APD356, a selective 5-HT2C serotonin receptor agonist for the treatment of obesity. The results indicated that there were no apparent drug effects on heart valves or pulmonary artery pressure after four weeks of treatment. The ECHOs were taken from patients roughly 90 days after their first APD356 dosing. The company had announced full results from the trial in May 2005. The trial demonstrated that patients taking the 15 mg dose of APD356 achieved a mean weight loss of 2.9 pounds compared with 0.7 pounds for patients taking placebo, a statistically significant (p=0.0002) difference. The company also reported completion of enrollment in its phase IIb trial with APD356 in 460 patients. Initial results are expected near the end of 2005.
July 4, 2005
TolerRx reported positive results of a phase II study of their humanized monoclonal antibody TRX4, for the treatment of Type I diabetes. Administration of TRX4 was seen to significantly reduce need for increases in daily insulin dose compared to placebo, especially in the subgroup of patients with greater-than-median beta cell function at study outset. Mean daily insulin dose at 18 months was 0.22 IU/kg for this subgroup, vs. 0.61 IU/kg for placebo (p<0.001); 75% of subjects received minimal insulin doses in this group, vs. 0% for placebo. This double-blind, placebo- controlled study enrolled 80 patients with Type I diabetes across 5 sites in France, Belgium, Germany, and England, who received treatment with TRX4 (n=40) or placebo (n=40) for 6 consecutive days, with follow-up examination of daily insulin needs and beta cell function through 18 months.
June 20, 2005
Agennix reported positive results of a phase II study of their topical formulation of talactoferrin alfa, under investigation for the treatment of diabetic neuropathic ulcers. Safety data yielded positive results, with no drug- related adverse events noted and no incidence of infection of target ulcers during the dosing period. Primary efficacy data me their pre-specified endpoint, with subjects receiving the drug achieving 75% or better would healing roughly twice as often as subjects receiving placebo (p<0.05). This sequential-stage dosing study enrolled a total of 55 patients with diabetic neuropathic ulcers. Subjects enrolled in the open-label first stage received twice daily treatments with one of three doses of the drug (1%, 2.5% or 8.5%) for 30 days. In the randomized, placebo- controlled dosing stage, subjects received one of two doses of the drug (2.5% or 8.5%) or placebo in combination with good wound care for 12 weeks.
Bentley Pharmaceuticals announced positive results of a phase II trial of their investigational intranasal insulin, for the treatment of type 1 diabetes. Initial study results indicated that the intranasal formulation demonstrated more rapid absorption and higher peak plasma levels than injectable (subcutaneous) insulin. The drug achieved a calculated relative bioavailability of 15-20%, compared to established values for injectable insulin; this level is higher than those reported in most studies of inhaled insulin formulations. Furthermore, the drug successfully controlled post-prandial hyperglycemia for over two hours, indicating clinical utility. This open-label study enrolled 7 subjects with type 1 diabetes at a single site in Ireland. The company indicated that these initial results supported further development efforts in the near future.
Isis Pharmaceuticals announced positive interim results of a phase II study of ISIS 113715, their second generation antisense PTP-1B inhibitor for the treatment of type II diabetes. Efficacy data from the frist two dosing cohorts indicated that the drug produced a dose-dependent reduction in HbA1C from placebo at 6 weeks: it reduced HbA1C by 0.25% at the low dose (100 mg), and, 0.4% at the higher dose (200 mg). The drug also produced dose-dependent increases in the percentage of patients who achieved the target HbA1C level of 7%, with 33% and 45% of the patients respectively, vs. 25% of the patients in the placebo group. Finally, both doses were seen to reduce fasting plasma glucose by roughly 25mg/dL compared to placebo. This randomized, double-blind, placebo-controlled trial will eventually enroll patients into one of 4 weekly dosing regimens (100 mg, 200 mg, 400 mg and 600 mg) or placebo for 6 weeks. The company announced plans to initiate additional trials of the drug in combination with approved oral anti-diabetic agents later in 2005.
Merck reported combined results of three phase II trials of their investigational dipeptidyl peptidase IV inhibitor sitagliptin (MK-0431), for the treatment of type II diabetes. The pooled data indicated that the drug was efficacious in reducing hyperglycemia, with 12 weeks of treatment producing significant mean reductions in HbA1C levels compared to placebo for both once-and twice-daily dosing regimens. Furthermore, the addition of the drug to a standard regimen of metformin yielded improved 24 hour glycemic control vs. metformin alone, without increased incidence of adverse events. The first two studies were 12- week, randomized, double-blind, placebo-controlled trials: the first enrolled 552 patients into one of 5 dosing groups (25 mg, 50 mg, or 100 mg once daily, 50 mg twice daily, or placebo); the second enrolled 743 subjects into one of 6 groups (5 mg, 12.5 mg, 25 mg, or 50 mg sitagliptin twice daily, placebo, or the sulfonylurea glipizide 5 mg titrated to 20 mg daily). The third study was a randomized, double- blind, placebo-controlled, four-week crossover study, which evaluated the efficacy and tolerability of the addition of sitagliptin or placebo to a standard regimen of metformin.

Bristol-Myers Squibb and Merck issued results of a phase III trial of muraglitazar, their dual alpha/gamma PPAR activator under investigation for the treatment of Type 2 diabetes, at the 14th Annual Meeting of the American Association of Clinical Endocrinologists. Trial results indicated that the drug produced a significant reduction from baseline in hemoglobin A1C (HbA1c) levels in both low dose (-1.05%) and high dose (-1.23%) cohorts, vs. placebo (-.032%; p<0.0001). The portion of subjects achieving target HbA1C levels (<6.5%) were achieved by 36% and 58% of muraglitazar subjects, respectively, vs. 18% for placebo. Secondary efficacy was noted in reducing serum triglyceride levels in the high dose cohort (-30.4% vs. -13.2%; p= 0.0002), and in increasing serum HDL-C levels in both cohorts (+10%, +16%, vs. +2%; P<0.0001). In an additional open-label cohort of subjects with high HbA1C levels, mean HbA1C levels fell by 2.62%. This multicenter, parallel-group study enrolled a randomized, double-blind, placebo-controlled cohort of 340 subjects with inadequately controlled diabetes (HbA1C levels: 7%-10%), and an additional open-label cohort of 109 patients with high HbA1C levels (10%-12%). All subjects received once-daily treatment for 24 weeks; subjects in the double-blind cohort received one of two doses of muraglitazar (2.5 mg or 5 mg) or placebo, while subjects in the open- label cohort all received the 5 mg dose.

The open-label, single-center, active comparator study enrolled 20 subjects with type 1 diabetes who received multiple daily injections for at least five years. Subjects received Oralin given immediately prior to a standardized meal, the same dose split between two administrations before and after meal or regular human insulin administered 15 minutes prior to the meal. The study was designed to compare the pharmacokinetic and glucodynamic profiles of Oralin.
May 10, 2004
Aradigm and Novo Nordisk reported interim results from a phase III trial investigating AERx iDMS, a pulmonary insulin product for the treatment of diabetes. Results showed that the trial met its primary safety endpoints with no change in pulmonary function tests and no adverse effects reported. Data showed that the efficacy endpoint of the trial, HbA1c levels, was statistically the same in the AERx and subcutaneous groups. However, analysis showed delayed post-meal plasma glucose suppression in subjects with type I diabetes. In the immediate post-meal period, plasma glucose levels were higher, and during the nighttime, plasma glucose levels were lower in the AERx iDMS group compared with the subcutaneous group. Due to these results, Novo Nordisk decided to end the study earlier than had been initially planned.
April 19, 2004

August 11, 2003
Amylin Pharmaceuticals and Eli Lilly reported positive results from the first of three phase III trials investigating exenatide, a synthetic exendin-4 for the treatment of type 2 diabetes. Results showed statistically significant reductions in the primary glucose control endpoint in subjects failing to achieve target blood glucose levels with metformin alone. Subjects receiving exenatide also showed statistically significant reductions in body weight. Observed rates of hypoglycemia were the same between the exenatide and placebo groups. Data demonstrated that 46%of the subjects receiving the highest dose of exenatide reduced their average glucose levels less than or equal to 7%. The randomized, placebo controlled study enrolled 336 subjects with type 2 diabetes who were not achieving target blood glucose levels with metformin alone. Subjects were given a 5-ug dose of exenatide, twice a day, for one month by subcutaneous injection. This was followed by six months of exposure to doses of either 5 ug or 10 ug given twice a day at breakfast and dinner.
DepoMed and Biovail reported positive results from a post marketing trial investigating Metformin GR for the treatment of type II diabetes. Results showed that Metformin GR consistently lowered values of hemoglobin A1C (HbA1c), an indicator of long-term control of glucose levels. Data also demonstrated that treatment with Metformin GR lowered fasting plasma glucose levels compared to baseline, another measure commonly used to evaluate the effectiveness of diabetes medications. The 24-week, open label extension study enrolled 250 patients with Type II diabetes who had completed the prior 24-week phase III trial. Metformin GR was safe and well tolerated. These findings reinforce the results of a 24-week, double blind, placebo-controlled Phase III trial evaluating various doses of Metformin GR compared to Bristol Myers Squibb's Glucophage (immediate release metformin).
July 14, 2003
Emisphere Technologies reported positive results from two studies investigating Emisphere Oral Insulin for the treatment of type 2 diabetes. The first was an open-label, randomized, two-period crossover, proof-of-concept study conducted at the Profil Institute in Germany. Data demonstrated an appropriate reduction in blood sugar following the oral insulin administration and a tight range of time to maximum insulin. The study used the Glucose Clamp Technique to assess insulin secretion and resistance based on measuring the rate of a glucose infusion. The second study evaluated the overnight effects of the oral insulin in 20 type 2 diabetic subjects and was conducted at Hadassah University Hospital in Israel. Results demonstrated that the metabolic effect of a single dose of oral insulin was still apparent in the morning. The oral insulin was well tolerated with no serious adverse events were reported. Results were presented at the 63rd Annual Scientific Sessions of the American Diabetes Association in New Orleans.
July 7, 2003

The primary endpoint, relative insulin response through glucose tolerance, showed no clinically or statistically significant differences among the treatment groups compared to placebo. Data also showed a dose-dependent increase in the blood levels of IGF-1, a marker of the anabolic effects of ThGRF and a decrease in atherogenic cholesterol levels. At the end of the treatment period, IGF-1 levels increased on average by 32 % (1 mg group) and 67 % (2 mg group). The double blind, randomized, placebo-controlled study enrolled a total of 53 subjects over age 50 with type II diabetes.
July 29, 2002
Novo Nordisk A/S has decided to suspend the clinical development of ragaglitazar (NN 622), a dual-acting insulin sensitizer. The decision was prompted by findings of urine bladder tumors in one mouse and a number of rats treated with ragaglitazar. All current clinical trials involving ragaglitazar have been halted. Furthermore, all planned new trials have been postponed while the preliminary pre-clinical data is investigated. Ragaglitazar is a peroxisome proliferator-activated receptor (PPAR) alpha and gamma agonist that was in-licensed by Novo Nordisk from Dr. Reddy's Laboratories.
May 6, 2002
Positive results were reported from a phase III trial of Aventis and Pfizer's Exubera (inhaled insulin) in type 1 diabetic subjects. The six-month trial included 335 subjects between the ages of 12 and 65. The trial was designed to compare Exubera administered prior to meals, plus one injection of long-acting insulin taken at bedtime, to two to three insulin injections per day. Results showed that glycated hemoglobin (HbA1c) decreased similarly for subjects taking Exubera and one insulin injection compared to those receiving multiple insulin injections. Subjects receiving Exubera also experienced significantly greater decreases in fasting plasma glucose concentrations and two-hour postprandial glucose levels. Furthermore, subjects treated with inhaled insulin experienced fewer hypoglycemic events than those receiving the multiple insulin injections.
April 8, 2002
Results from two phase III trials suggest that Pharmacia's eplerenone produces a greater reduction in proteinuria than enalapril in diabetic hypertensive subjects. Additionally, results showed that the two drugs similarly reduced left ventricular mass (LVM). Both trials evaluated treatment with eplerenone, enalapril, and eplerenone in combination with enalapril. The studies were designed to control blood pressure equally in all treatment groups to allow for evaluation of eplerenone's effect on proteinuria and left ventricular hypertrophy (LVH). In the first trial, which included diabetic subjects with hypertension and albuminuria, treatment with eplerenone resulted in a 62% reduction in proteinuria, compared to a 45% reduction with enalapril and a 74% reduction with the combination therapy. In the second trial, which included hypertensive subjects with LVH, eplerenone and enalapril treatment produced reductions of 14.5g and 19.7g in LVM, respectively. LVM reduction in the combination therapy group was 27.2g.
February 19, 2002
Study results indicate that taking Novo Nordisk's Prandin (repaglinide) tablets with three main daily meals produced greater improvements in certain measures of glycemic control than twice-daily dosing. In the double-blind trial, 19 type 2 diabetic subjects received either a 0.25mg dose of repaglinide before each of the three meals, or a 0.5mg dose before breakfast and a 0.25mg dose before the evening meal. Mealtime dosing was doubled after two weeks to a total daily dose of 1.5mg in both groups. Repaglinide tablets are known as Prandin in the United States, NovoNorm in Europe and Gluconorm in Canada.
