OncoGenex Pharmaceuticals reported
results of a phase II study of apatorsen in
combination with gemcitabine/cisplatin chemotherapy
compared to chemotherapy alone
in the treatment of metastatic bladder cancer.
The trial, Borealis-1, enrolled approximately
180 patients with documented metastatic or
locally inoperable transitional cell carcinoma
(TCC) of the urinary tract who previously
had not received chemotherapy for metastatic
disease and were not candidates for
potentially curative surgery or radiotherapy.
Patients were randomized to receive standard
chemotherapy (gemcitabine/cisplatin) in
combination with apatorsen at two dose levels
(600mg and 1,000mg) or gemcitabine/cisplatin
plus placebo. Patients received up to six
cycles of weekly intravenous therapy. Overall
trial results indicated the addition of 600mg
apatorsen to standard of care chemotherapy
showed a 14% reduction in risk of death
(overall survival hazard ratio (HR) = 0.86) and
a 17% reduction in progressive disease and
death (progression-free survival HR = 0.83)
when compared to chemotherapy alone. Over
one-third of the patients in the trial had lower
performance status, as defined by a Karnofsky
score of 80% or less. These patients derived
the greatest benefit from 600mg apatorsen
in combination with chemotherapy, resulting
in a 50% reduction in risk of death (overall
survival HR = 0.50) compared to chemotherapy
alone. Less benefit was observed in
the 1000mg apatorsen arm due to increased
adverse events leading to a higher rate of discontinuation
of both apatorsen and chemotherapy.
Apatorsen 600mg was well tolerated
in combination with chemotherapy.

Merck reported results for a phase III
study of EMEND (aprepitant) in the prevention
of chemotherapy-induced nausea and
vomiting (CINV) in pediatric cancer patients,
aged 6 months to 17 years. In the randomized,
study of 302 participants, patients receiving
emetogenic chemotherapy were randomly
assigned to receive an EMEND plus ondansetron
regimen (n=152) or a control regimen
(placebo plus ondansetron) (n=150). The
first dose of EMEND (plus ondansetron) was
administered on day one of chemotherapy,
then subsequently (without ondansetron)
later on days two and three. In the study,
51% of patients receiving the EMEND
regimen achieved the primary endpoint of
complete response in the delayed phase
of CINV, versus 26% of those in the control
group (p<0.0001). For the secondary endpoints,
66% of patients receiving the EMEND
regimen achieved a complete response in
the acute phase of CINV, versus 52% of those
receiving the control regimen (p=0.0135). In
addition, complete response in the overall
phase was higher in patients receiving the
EMEND regimen versus the control regimen
(40% v. 20%, p=0.0002). No vomiting in the
overall phase was observed in 47% v. 21% of
patients receiving the EMEND regimen compared
to the control regimen, respectively
(p<0.0001). Merck plans worldwide regulatory
submissions for EMEND, beginning in
the U.S. in the second half of 2014.

Agenus released preliminary results from a phase II trial of Prophage G-100 (HSPPC-96) for glioblastoma multiforme (GBM). This single-arm study enrolled 46 patients with newly diagnosed GBM. Subjects received the HSPPC-96 vaccination, as well as radiation and temozolomide as the standard of care. Results showed patients treated with the HSPPC-96 arm showed a 146% increase in progression-free survival (PFS) over standard of care alone (17 months versus 6.9 months, respectively) and a 60% increase in overall survival (OS) over standard of care alone (23.3 months versus 14.6 months, respectively). In addition, 32 patients treated at UCSF underwent testing for expression of B7-H1 in blood samples taken prior to surgery, which showed patients with low expression of B7-H1 (53%) had better PFS (21.6 months) than those with high B7-H1 (47%) expression (11.4 months). This finding may have the potential to help identify a more responsive patient population for future trials.
Amgen issued results from a phase III head-to-head trial of Vectibix (panitumumab) versus Erbitux (cetuximab) for chemorefractory metastatic colorectal cancer (mCRC). This global, randomized, parallel-assignment, open-label, non-inferiority study enrolled 1,010 patients with mCRC with wild-type KRAS tumors. Subjects received 6mg/kg of intravenous Vectibix every 14 days or 400mg/m2 of an initial dose of intravenous Erbitux followed by 250mg/m2 of intravenous Erbitux every seven days. Data demonstrated the estimated overall survival hazard ratio (Vectibix/Erbitux) was 0.966 (95% CI: 0.839, 1.113) favoring the Vectibix arm. Vectibix was well tolerated. Overall, the relative adverse event profiles were as anticipated for each of the anti-EGFR therapies studied, including known events such as rash, diarrhea and hypomagnesemia.

Navidea Biopharmaceuticals issued interim results from a phase III trial of Lymphoseek (technetium 99m tilmanocept) for identifying sentinel lymph nodes (SLNs) in patients with head and neck squamous cell carcinoma. This open-label, multicenter, within-patient study, NEO3-06, enrolled 80 patients with head and neck squamous cell carcinoma. After receiving a Lymphoseek injection, 39 of the 80 patients were determined to have pathology-positive lymph nodes. Results demonstrated of these 39 patients, Lymphoseek accurately identified 38, for an overall False Negative Rate (FNR) of 2.56%, which was statistically significant (p=0.0205) and met the statistical threshold for success of the primary endpoint. Moreover, multiple-level nodal dissection of patients in the trial with cancer-positive lymph nodes led to an average removal of 38 lymph nodes per patient, whereas Lymphoseek on average led to the removal of approximately four lymph nodes, representing a substantial reduction in potential morbidity for patients with head and neck cancer undergoing sentinel lymph node biopsy. Based on these data, Navidea Biopharmaceuticals will evaluate the possibility of filing a Supplemental New Drug application (sNDA) later this year.

Peregrine Pharmaceuticals issued results from a phase II trial of bavituximab for the treatment of non-small cell lung cancer (NSCLC). This Peregrine's randomized, double-blind, placebo-controlled study enrolled 121 patients with previously treated locally advanced or metastatic second-line NSCLC. Subjects received bavituximab 3mg/kg plus docetaxel or placebo plus docetaxel. Results showed a meaningful improvement in median overall survival of 11.7 months in the bavituximab plus docetaxel arm compared to 7.3 months in the control arm (HR=0.73; p value=0.217). Persistent separation in the survival curves was observed with response rates and progression-free survival also favoring the bavituximab plus docetaxel. Bavituximab was well tolerated. The most frequent adverse events were similar between both treatment arms. Based on these data, Peregrine is preparing for an end-of-phase II meeting with the FDA.
February 25, 2013
Progenics Pharmaceuticals released results from a phase I trial of PSMA ADC for prostate cancer. This open-label, dose-escalation study enrolled 52 men with metastatic castration-resistant prostate cancer that had progressed despite prior treatment with taxane-based chemotherapy regimens. Subjects received nine different dosing levels of PSMA ADC administered at three-week intervals for 12 weeks. Significant antitumor activity was observed across doses ranging from 1.8mg/kg to 2.8mg/kg. PSMA ADC was generally well tolerated in patients at doses up to and including 2.5mg/kg, the maximum tolerated dose. Dose limiting toxicities, primarily neutropenia, were seen at 2.8mg/kg. The most frequent adverse events were anorexia and fatigue. Progenics Pharmaceuticals initiated a phase II, open-label, multicenter study of PSMA ADC.

AVEO Oncology and Astellas Pharma reported results from a phase III trial of tivozanib compared to sorafenib for the treatment of advanced renal cell carcinoma (RCC). This global, randomized study, TIVO-1, enrolled 517 patients with RCC. Subjects received either tivozanib or sorafenib. The final overall survival (OS) analysis showed a median OS of 28.8 months (95% confidence interval [CI]: 22.5–NA) for tivozanib versus a median OS of 29.3 months (95% CI: 29.3–NA) for the comparator arm, sorafenib. No statistical difference between the two arms (HR=1.245, p=0.105) was observed. Patients randomized to the sorafenib arm were eligible to cross over to tivozanib therapy under a separate protocol after radiographic confirmation of disease progression. No crossover protocol was available for patients randomized to the tivozanib arm. Tivozanib was well tolerated. Based on these data, AVEO and Astellas have filed a New Drug Application (NDA) for tivozanib for the treatment of RCC.
Peregrine Pharmaceuticals released results from a phase II trial of bavituximab in combination with gemcitabine Stage IV pancreatic cancer. This open-label, randomized study enrolled 70 patients with previously untreated, advanced Stage IV pancreatic cancer. Subjects received either bavituximab in combination with gemcitabine, or gemcitabine alone. Data demonstrated the combination of bavituximab and gemcitabine resulted in more than a doubling of overall response rates (ORR) and an improvement in overall survival (OS) when compared with gemcitabine. Subjects treated with a combination of bavituximab and gemcitabine had a 28% tumor response rate as compared to 13% in the control arm. Median OS, the primary endpoint of the trial, was 5.6 months for the bavituximab plus gemcitabine arm and 5.2 months for the control arm (HR=0.75). Bavituximab was generally safe and well tolerated, with similar adverse events occurring in both arms. Peregrine is evaluating the next steps for advancing the bavituximab pancreatic program to include combination with other cancer agents. Bavituximab is currently being evaluated in patients with non-small cell lung, breast, prostate, liver and rectal cancers in combination with approved chemotherapies and radiation.

Amgen issued results from a phase III trial of Neulasta (pegfilgrastim) for the treatment of colorectal cancer. This multinational, randomized, double-blind, placebo-controlled trial enrolled 845 patients receiving FOLFOX or FOLFIRI and bevacizumab for the first-line treatment of locally-advanced or metastatic colorectal cancer. Subjects received 6mg of Neulasta, or placebo, at least 24 hours after each cycle of chemotherapy. Results showed the study met its primary endpoint: Neulasta significantly reduced the incidence of febrile neutropenia (low white blood cell count accompanied by a fever). In the study, the incidence of grade 3 or 4 febrile neutropenia in patients receiving Neulasta across the first four cycles of chemotherapy was 2.4%, compared to 5.7% in the placebo group (OR=0.41, p=0.014). A similar incidence of grade 3 or higher adverse events was seen in both arms of the trial (28% placebo; 27% Neulasta). The drug was well tolerated. Amgen did not note its plans for Neulasta.
January 7, 2013
Bristol-Myers Squibb reported results from a phase II trial of elotuzumab in combination with lenalidomide and low-dose dexamethasone for the treatment of multiple myeloma. This randomized, multi-center, open-label study enrolled patients with previously treated multiple myeloma. Subjects received either 10mg/kg or 20mg/kg of elotuzumab intravenously on days 1, 8, 15 and 22 of a 28-day cycle in the first two cycles, and then on days 1 and 15 of subsequent cycles. Subjects also received lenalidomide 25mg PO daily on days 1 to 21 and dexamethasone 40mg PO weekly. Results demonstrated in the 10mg/kg arm, median progression-free survival (PFS) was not reached after 20.8 months of follow up (n=36) and the objective response rate (ORR; according to the International Myeloma Working Group response criteria) was 92%. Of patients who received elotuzumab at a dose of 20mg/kg, median PFS was 18.6 months (n=37) and ORR was 76%. Elotuzumab was well tolerated. The most frequent adverse events were lymphopenia, neutropenia, thrombocytopenia, anemia, leukopenia, hyperglycemia, pneumonia, diarrhea, fatigue and hypokalemia. BMS also is studying elotuzumab in two phase III trials for treatment of relapsed/refractory multiple myeloma.

Boehringer Ingelheim issued preliminary results from a phase II trial of volasertib for the treatment of acute myeloid leukemia (AML). This open-label study enrolled 87 patients with newly-diagnosed AML who were considered ineligible for intensive remission induction therapy. Subjects received volasertib in combination with low-dose cytarabine (LDAC) (n=42) or LDAC alone (n=45). Results showed objective responses were observed in 31% of patients (13/42) treated with the combination of volasertib plus LDAC compared with 13.3% of the patients (6/45) treated with LDAC alone (odds ratio: 2.91; p=0.0523). The median time to remission was 71 (29158) days and 64 (30125) days, respectively. Data also showed that in patients treated with the combination of volasertib plus LDAC, the median event free survival was approximately 5.6 months (170 days) compared with approximately 2.3 months (69 days) in patients treated with LDAC alone (hazard ratio: 0.56; 95% CI: 0.34, 0.93; p=0.0237). Volasertib was well tolerated. The most frequent adverse events were gastrointestinal events, general events, infections, febrile neutropenia, metabolism/nutrition events and respiratory/thoracic/mediastinal events. Based on these data, Boehringer Ingelheim intends to begin recruitment of a phase III study of volasertib in combination with LDAC compared with LDAC alone in early 2013.
Celgene International released results from a phase I trial of CC-486 (oral azacitidine) for the treatment of myelodysplastic syndromes (MDS). This multi-arm study enrolled 53 patients with lower-risk MDS who were red blood cell transfusion-dependent and/or thrombocytopenic. Subjects received 300mg of CC-486 once daily for either 14 or 21 days of each 28-day cycle. After a median of seven treatment cycles for the 14-day treatment arm and five for the 21-day treatment arm, the overall response rate was 42.3% (11/26) and 37.0% (10/27), respectively. Additionally, the percentage of patients showing any hematologic improvement was 26.9% in the 14-day arm and 29.6% in the 21-day arm. The percentage of patients who sustained RBC transfusion independence for 56 days was 53.5% in the 14-day arm and 40.0% in the 21-day arm. The percentage of patients who sustained RBC transfusion independence for 84 days was 20% in the 14-day arm and 33.3% in the 21-day arm. CC-486 was well tolerated. The most frequent adverse events were anemia, thrombocytopenia, neutropenia and febrile neutropenia. Based on these and other early-stage data evaluating CC-486, Celgene plans to initiate two phase III studies (QUAZAR program) evaluating this oral agent in lower-risk MDS and acute myeloid leukemia by the end of 2012.

Aeterna Zentaris reported results from a phase I trial of perifosine combined with temsirolimus for the treatment of malignant glioma. This combination, dose-ranging study enrolled 32 patients with recurrent or progressive malignant glioma, anaplastic astrocytoma, anaplastic oligodendroglioma and transformed low-grade gliomas with median Karnofsky Performance Status 80. Subjects either received a 600mg or 900mg dose of perifosine on day one, followed by a nightly dose of 100mg of perifosine. All subjects also received 15mg to170mg of temsirolimus once weekly. Preliminary survival results demonstrated that median overall survival was 7.4 months. There were 27 radiographic responses: complete response (0), partial response (2), stable disease (13) and progressive disease (12). The most frequent adverse events were hypophosphatemia, hypocholesterolemia and hypertriglyceridemia. The maximum tolerated dose was not defined, so Aeterna Zentaris is creating expansion cohorts.
OncoSec Medical issued preliminary results from a phase II trial of ImmunoPulse for the treatment of metastatic melanoma. This single-arm, open-label and multi-center study has enrolled 13 patients with stage III or IV cutaneous and in-transit metastatic melanoma, of 25 patients expected. Subjects received a maximum dose of 1.5mg of DNA IL-12 via ImmunoPulse on days one, five and eight, applied to up to four lesions. Subjects also received electroporation treatment. Results suggested that ImmunoPulse is able to induce regression or stabilization of distant untreated metastases following a single cycle of treatment. Ninety-five percent of treated lesions demonstrated response at day 39 (5% progressive disease, 14% stable disease (SD), 42% partial response (PR), 39% complete response (CR)). All treated lesions at day 90 (5% SD, 50% PR, 45% CR), and at day 180 (33% PR, 67% CR) demonstrated a response. At day 180, two subjects were evaluable for the primary endpoint of objective overall response (ORR). One patient has a confirmed stable disease, and the second patient has a confirmed complete response of all treated and untreated lesions. ImmunoPulse and DNA IL-12 were well tolerated. The most frequent adverse events were generally limited to transient pain related to electroporation treatment. OncoSec Medical will continue the phase II study, which it expects to be completed by the end of 2012.
November 5, 2012
Alliance for Clinical Trials in Oncology released results from a phase III trial of doxepin for the treatment of head and neck cancer. This multi-institution, randomized, double-blind, placebo-controlled study enrolled 140 patients who were also receiving radiation therapy for their head and neck cancer (>50.0Gy), which involved more than one-third of the oral cavity. Subjects received a single, blinded dose of doxepin rinse (doxepin 25mg in 5ml of water) or placebo on day one, and then crossed over to the opposite study group on a subsequent day. Results indicated that the addition of doxepin significantly decreased pain, which was measured by the area under the curve (AUC) on the pain scale over time. Patients who received doxepin reported a reduction in pain to a -9.1 versus -4.7 for those who received the placebo. Analysis of the crossover data revealed similar findings, with an AUC score of -7.9 in the doxepin group versus -5.6 in the placebo group. Sixty-four percent of patients elected to continue doxepin after the study was completed. Doxepin was well tolerated. The most frequent adverse events were stinging/burning, unpleasant taste and greater drowsiness.
Specialised Therapeutics Australia issued results from a phase III comparative trial of Abraxane versus standard chemotherapy for the treatment of metastatic melanoma. This randomized, open-label, international study enrolled 529 chemotherapy-naïve patients. Subjects received either Abraxane 150mg/m2 weekly for three out of four weeks, or dacarbazine 1000mg/m2 every three weeks. The Abraxane arm showed statistically significant improvement in progression-free survival (PFS) (4.8 months) compared to patients receiving dacarbazine chemotherapy (2.5 months) (HR:0.792; 95.1% CI: 0.631, 0.992; P=0.044). Data shows overall survival trends in favor of the Abraxane arm (12.8 months) compared to dacarbazine (10.7 months) (HR:0.831; 99.9% CI: 0.578, 1.196; P=0.094). The drug was well tolerated. The most frequent adverse events were neuropathy and neutropenia. Specialised Therapeutics Australia hopes to have Abraxane approved by the Therapeutic Goods Administration in Australia by 2014.

Jennerex reported results from a phase II trial of JX-594 for the treatment of hepatocellular carcinoma (HCC). This nonrandomized study enrolled 25 Asian patients with advanced HCC; 20 were refractory to sorafenib and were treated with an intravenous dose of JX-594, while the majority of patients then received sequential intra-tumoral doses of JX-594 at week one and three. The majority subsequently received treatment with sorafenib. The study met its primary endpoint of determining the safety of JX-594 followed by sorafenib in patients with advanced HCC. After six or 12 weeks, 59% had disease control as measured by modified RECIST and 75% had objective responses by Choi criteria. 85% of patients had disease control by mRECIST or Choi response. The sequential treatment regimen was well tolerated with transient flu-like symptoms, with the most common adverse event being transient leukopenia. Jennerex is planning several phase II studies of JX-594 in liver cancer, HCC and colorectal cancer.
August 27, 2012
Medivation and Astellas Pharma published results from a phase III trial of enzalutamide for the treatment of metastatic castration-resistant prostate cancer. This international, randomized, double-blind, placebo-controlled study, AFFIRM, enrolled 1,199 men who had been previously treated with docetaxel-based chemotherapy. Subjects received enzalutamide 160mg once daily (as four 40mg capsules), or placebo. Data showed enzalutamide exhibited a statistically significant benefit in overall survival compared to placebo. Men treated with enzalutamide had a median overall survival of 18.4 months (95% confidence interval, 17.3 to not yet reached) compared to 13.6 months (95% confidence interval 11.3-15.8) for men treated with placebo (hazard ratio 0.63; p<0.0001), representing a 37% reduction in the risk of death. The drug was well tolerated. The most frequent adverse events were fatigue, diarrhea and hot flush. Seizure was reported in less than 1% of enzalutamide-treated patients. Neither Medivation nor Astellas noted its next steps for enzalutamide.
July 9, 2012
A.P. Pharma issued results from a phase III comparative study of APF530 and palonosetron (Aloxi) for the treatment of chemotherapy-induced nausea and vomiting. In this multi-center, randomized, observerblind, actively-controlled, double-dummy, parallel group study, subjects received APF530 high dose (10mg granisetron), APF530 low dose (5mg granisetron) or the currently approved dose of palonosetron. Patients used a daily diary to record severity of nausea, vomiting episodes, use of rescue medication and satisfaction with nausea/vomiting control over a five-day period following chemotherapy. Analysis indicated that both doses of APF530 offered comparable nausea control and patient satisfaction to palonosetron over a five-day period. The drug was safe and well tolerated. A.P. Pharma will continue to analyze the phase III data.
October 20, 2008
GTx issued positive results from a phase IIb trial of ostarine for the treatment of cancer cachexia. This randomized, double blind, placebo controlled study enrolled 150 subjects with various cancers in the US and Argentina. The subjects received Ostarine 1 mg, Ostarine 3 mg or placebo once daily for four months. The primary endpoint was change in total lean body mass at 16 weeks. Topline results show that Ostarine treatment resulted in a statistically significant increase in lean body mass compared to placebo. Both doses of Ostarine also resulted in clinically meaningful increases (greater than 1 kg) in lean body mass compared to baseline. In addition, Ostarine treatment improved muscle function in a 12 step stair climb test measuring speed and calculating power, a secondary endpoint of the study. Treatment was well tolerated; adverse events were similar across the study arms. Based on the results, GTx plans to move forward with the development of Ostarine.
June 9, 2008
Celator released positive results from a phase II trial of CPX-1 for the treatment of colorectal cancer. This multi-center, open-label study enrolled 59 subjects who were placed in two arms: irinotecan-naive (IRI-naive) and irinotecan-refractory (IRI-refractory) and received 210 units/m2 of CPX-1 every two weeks. In the IRI-naive arm the overall response rate was 8% and the disease control rate (response or stable disease) was 65 percent. Median progression- free survival (PFS) was 3.9 months and six subjects had a greater than six month PFS. In the IRI-refractory arm the disease control rate was 45%; there were no reports of an objective response. The median PFS was 2.3 months and three subjects had a greater than six month PFS. The 210 unit/m2 dose produced more toxicities than seen in previous phase 1 studies, resulting in only 40 percent of the subjects receiving more than 80 percent of the planned dose intensity. Hence, treatment will be initiated at a lower dose in future studies. Based on the results Celator plans to move forward with the development of CPX-1.
February 12, 2007
Adnexus released announced positive interim results from a phase I trial of Angiocept for the treatment of cancer. This open label, dose escalation trial was designed to assess the safety, tolerability and pharmacokinetics of the drug in cancer subjects as well as to evaluate preliminary anti-tumor and biological activity. Interim evidence revealed that within four hours of drug administration biological activity occurred, as evidenced by elevated plasma levels of biomarkers of VEGFR-2 pathway. These biomarkers remained significantly elevated above baseline throughout the multi-dose treatment duration. Pharmacokinetic data demonstrated a profile that could support an every other week dosing regimen. The maximum tolerated dose has not been reached. Based on the results, the development of Angiocept is to continue for this indication.
Celtic announced negative results from phase III trial, dubbed KSB311R/CIII/001, of TransMID for the treatment of glioblastoma multiforme. This randomized, open-label trial was to include tow sequential trials. The first planned to enroll 323 subjects with non-resectable, progressive or recurrent Glioblastoma Multiforme (GBM) who had failed conventional therapy, in North America, the EU and Isreal. It was designed to compare two intratumoral doses of TransMID to best standard of care in improving overall survival. The trial's primary efficacy endpoint was overall survival time; interim analysis was to occur when 50% of the required events were observed. The interim assessment revealed that the probability of the trial achieving the predefined overall survival rate by the trial end was unlikely to occur. Based on this data, Celtic decided to terminate the development of TRansMID for this or any other indication.
Spectrum released positive results from a pilot phase II trial of EOquin for the treatment of non-invasive bladder cancer. This single-arm, open-label study enrolled 20 subjects who received 4 mg of EOquin in 40 mL of diluent administered via an indwelling catheter that was then clamped for one hour. After an hour the bladder was drained and the catheter was removed. Subjects were assessed for adverse events during the one hour retention and at post-operative days eight and fifteen. Wound healing, assessed by cystoscopy performed at postoperative day 85, and systemic absorption were also evaluated. Treatment was well tolerated and no adverse events occurred on wound healing. In addition, EOquin was not systematically absorbed into the bloodstream when given immediately after surgery. A phase III protocol has been submitted to the FDA for a Special Protocol Assessment (SPA). Spectrum plans to start this trial in mid-2007.
October 23, 2006
Antisoma released positive results from a phase II trial of ASI1404 for the treatment of ovarian cancer. This trial enrolled 77 women with ovarian cancer that had recurred six months or more after treatment with platinum chemotherapy. Subjects were randomized to receive either AS1404 in combination with carboplatin and paclitaxel or carboplatin and paclitaxel alone. Treatment was well tolerated with no serious adverse events reported. Efficacy data revealed that of the subjects in the ASI1404 treatment group, 75.0% had a complete or partial response, 19.4% had stable disease and 5.6% had progressive disease, versus the control group at 63.2%, 28.9% and 7.9%, respectively. Based on the data Antisoma plans to begin development of phase III trials.
Wilex issued positive two year data from a phase II study of Rencarex, in combination with low dose Interferon alpha-2a, for the treatment of renal cell cancer (RCC). This trial enrolled 31 subjects with RCC who had the affected kidney removed. The median survival rate was 30 months and a 57% of the subjects had a two year survival rate. In addition, the subjects who were treated for an additional 6 weeks past the original 12 week treatment phase had a statistically significant survival benefit when compared to those subjects who stopped treatment at 12 weeks. The median survival for those on continuing therapy was 45 months with a 2-year survival rate of 79 % versus a median survival of 10 months with a 2-year survival rate of 30 %. Rencarex is currently in phase III trials for the treatment of non-metastatic clear cell renal cell cancer.
August 21, 2006
Pharmexa issued negative results from a phase II trial of PX104.1, in combination with QS-21, for the treatment of breast cancer. This trial planned to enroll 40 subjects who were to receive four initial immunizations of PX 104.1 (1.25mg), formulated with Alhydrogel adjuvant and mixed with QS-21 adjuvant, for six weeks, followed by booster immunizations every four weeks, for up to 26 weeks. Preliminary results from the first 10 vaccinated subjects demonstrated that this formulation failed to meet the trial's primary endpoint of objective tumor response. The vaccine did not slow down tumor growth and cancer progressed in all 10 subjects. Based on these results the trial was stopped. Pharmexa intended to analyze further data for possible expansion into a different patient population.
Raven Biotechnologies, Inc. reported positive preliminary results from a phase I trial of RAV12 for the treatment of adenocarcinomas. Data has been evaluated from three treatment cohorts of 21 subjects who received RAV12, intravenously, in weekly escalating doses of 0.3 mg/kg to 1.5 mg/kg, for over four weeks. Safety and tolerability outcomes established a maximum tolerated dose with associated side effects of infusion-associated abdominal discomfort and liver function test abnormalities. Abdominal discomfort and liver function test abnormalities were transient at lower dose levels. Preliminary efficacy data revealed that treatment with RAV12 led to one subject achieving partial remission and three subjects with stable disease. In two subjects time to disease progression surpassed four months. The phase I trial was ongoing at this time.
April 3, 2006
Antigenics reported negative interim results of a phase III trial, dubbed C-100-12, of Oncophage (vitespen) for the treatment of renal cell carcinoma. Study data did not yield significant efficacy in the trial's primary endpoint, defined as recurrence free survival rate vs. surgical intervention alone, and its secondary efficacy endpoint, defined as overall survival, though a positive trend was noted in both measures. A lower-than expected incidence of disease recurrence was observed, relative to mortality; post-review investigation indicated that the number of disease progressions was below the threshold required to initiate this interim review. This randomized, international, multicenter, open-label study enrolled 728 patients, who nephrectomy alone or in combination with Oncophage therapy.
