Eli Lilly reported results of a phase III study of
ramucirumab in combination with chemotherapy
in patients with second-line non-small cell
lung cancer (NSCLC). The global, randomized,
double-blind trial compared ramucirumab and
docetaxel to placebo and docetaxel in NSCLC
patients whose disease has progressed after
failure of prior platinum-based chemotherapy
for locally advanced or metastatic disease.
Ramucirumab showed a statistically significant
improvement in overall survival in the
ramucirumab-plus-docetaxel arm compared
to the control arm of placebo plus docetaxel,
and a statistically significant improvement in
progression-free survival in the ramucirumab
arm compared to the control arm. The most
common (>5% incidence) Grade 3 adverse
events on the ramucirumab-plus-docetaxel
arm were decreased white blood cell count
(neutropenia/leukopenia), febrile neutropenia,
fatigue/asthenia and hypertension.

Eli Lilly released results of a phase III trial of necitumumab (IMC-11F8) in combination with gemcitabine and cisplatin as a first-line treatment, as compared to chemotherapy alone, for the treatment of with stage IV metastatic squamous non-small cell lung cancer (NSCLC). The trial enrolled 1093 patients (age greater than or equal to 18 years, ECOG PS 0-2) with histologically- or cytologicallyconfirmed, stage IV squamous NSCLC, who had received no prior therapy for metastatic disease. Patients underwent radiographic assessment of disease status (computed tomography or magnetic resonance imaging) every six weeks (+/- 3 days), until radiographic documentation of progressive disease (PD). The most common adverse events occurring more frequently in patients on the necitumumab arm were rash and hypomagnesemia. Serious, but less frequent, adverse events occurring more often on the necitumumab arm included thromboembolism. Lilly plans to present results from this study at a scientific meeting in 2014, and currently anticipates submitting to regulatory authorities before the end of 2014.

Boehringer Ingelheim issued results of a phase III study of afatinib in patients with advanced non-small cell lung cancer (NSCLC). Data from the LUX-Lung 3 trial demonstrate superiority of afatinib over chemotherapy considered best-in-class (pemetrexed/cisplatin) in EGFR-mutation positive advanced NSCLC patients. Patients treated with afatinib lived for almost one year (progression-free survival (PFS) of 11.1 months) before their tumor started to grow again compared to just over half a year (PFS of 6.9 months) for those treated with chemotherapy. Patients taking afatinib with the most common EGFR mutations (del19 and L858R, accounting for 90% of all EGFR mutations) lived for well over a year without progression (PFS of 13.6 months) v. just over half a year (PFS of 6.9 months) for those in the comparator arm. Afatinib significantly delayed the time to deterioration for cough (hazard ratio [HR], 0.60; P=0.007) and dyspnoea (HR, 0.68; P=0.015) and showed significantly better mean scores over time in global health status/QoL (P=0 .015) and physical (P<0.001), role (P=0.004) and cognitive (P=0.007) functioning compared with chemotherapy, as measured by standard questionnaires. The LUX-Lung clinical trial program currently involves eight studies designed to investigate the use of afatinib in various settings of advanced NSCLC, including head-to-head trials with the first-wave of reversible tyrosine kinase inhibitors.

Novartis reported results from a phase I trial of LDK378 for anaplastic lymphoma kinase positive (ALK+) metastatic non-small cell lung cancer (NSCLC) in patients who had progressed during or after crizotinib therapy or had not been previously treated with crizotinib. This single-arm study enrolled 114 patients. The results showed an overall response rate of 60% in patients with ALK+ NSCLC taking LDK378 (750 mg/day), which includes patients who had progressed during or after crizotinib therapy (overall response rate of 59%) and those who were crizotinib-naive (overall response rate of 62%). 78 patients were treated at 750mg/day; 36 patients were treated with LDK378 at 400-750mg/day. The median duration of response for patients treated at 400mg/day or higher (n=66) was 8.2 months (95% confidence interval [CI], 6.9-NE), with a median progression-free survival of 8.6 months (95% CI; 5.7-9.9). The six-month duration of response rate at 750mg/day was 61% (95% CI; 34.9-78.8). This trial will serve as the basis for the first regulatory filing, anticipated in early 2014.

Boehringer Ingelheim issued results from a phase III trial of LUME-Lung 1 for the treatment of advanced non-small cell lung cancer (NSCLC). This randomized, openlabel, double-blind study enrolled 1,314 patients with locally advanced or metastatic (stage IIIb/IV or recurring) NSCLC after first-line therapy. The subjects received nintedanib 200mg BID plus docetaxel 75mg/m(2) once a day for three weeks (n=655), or docetaxel plus placebo (n=659). LUME-Lung 1 improved progression-free survival (PFS)—the primary endpoint—as a second-line treatment in patients with NSCLC compared to docetaxel alone. Secondary endpoints included overall survival. Results showed patients treated with nintedanib plus docetaxel lived for a median of 3.4 months before their tumor started to grow again, versus 2.7 months with docetaxel alone (HR 0.79; p=0.0019). The most common adverse events (AEs) of any grade in the nintedanib combination and docetaxel alone groups were diarrhea (42.3% v. 21.8%, respectively) and ALT elevations (28.5% v. 8.4%, respectively). Incidence of > grade 3 AEs was 71.3% in patients treated with nintedanib plus docetaxel compared to 64.3% with docetaxel alone. A higher incidence of > grade 3 diarrhea and elevated ALT were observed in patients treated with nintedanib plus docetaxel compared to docetaxel alone (> grade 3 diarrhea: 6.6% v. 2.6%; elevated ALT: 7.8% v. 0.9%). Incidence of > grade 3 hypertension, bleeding and thrombosis were similar in both treatment arms. There was a 1% difference in discontinuation between the treatment arms, with 22.7% of patients stopping treatment with nintedanib plus docetaxel versus 21.7% with docetaxel alone.

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.

Boehringer Ingelheim released results from a phase III trial of afatinib for the treatment of non-small cell lung cancer (NSCLC). This randomized, open-label study enrolled 345 previously untreated patients with EGFR mutation positive NSCLC. Subjects received afatinib or standard chemotherapy agents (pemetrexed/cisplatin) as first-line treatment. Data showed afatinib-dosed patients had a progression-free survival (PFS) of 11.1 months versus a PFS of 6.9 months for those receiving pemetrexed/cisplatin. NSCLC patients with tumors harboring the two most common EGFR mutations (del19 and L858R) receiving afatinib had a PFS of 13.6 months versus a PFS of 6.9 months for those in the comparator arm. The afatinib-dosed arm experienced an improvement in shortness of breath, cough and chest pain, a delay in deterioration of these symptoms, and overall improved quality of life. Afatinib was well tolerated. Boehringer Ingelheim has initiated two head-to-head trials comparing afatinib to Iressa (gefitinib) and Tarceva (erlotinib), to demonstrate any potential efficacy and safety superiority.

Synta Pharmaceuticals reported interim results from a phase IIb/III trial of ganetespib in combination with docetaxel for the treatment of advanced non-small cell lung cancer (NSCLC). This multi-arm, randomized, open-label phase IIb part of the GALAXY study enrolled 183 patients to date with stage IIIB/IV NSCLC who have progressed following one prior line of therapy. All subjects received a standard regimen of docetaxel 75mg/m2 on Day 1 of a 21-day cycle; subjects in the combination arm receive in addition ganetespib 150mg/m2 on Day 1 and 15. Both primary endpoints were met based on RECIST 1.1 criteria. Subjects with elevated baseline level of serum LDH (lactate dehydrogenase) who received a combination of ganetespib and docetaxel had a median PFS of 4.2 months, compared to 1.4 months in those treated with only docetaxel; subjects with a tumor KRAS mutation receiving the combination treatment had a median PFS of 4.2 months, while the docetaxel group had a PFS of 1.6 months. The treatment was well tolerated. The most frequent adverse events were neutropenia, diarrhea and fatigue. Synta Pharmaceuticals will continue to enroll more subjects in the phase IIb trial. The transition into phase III is expected later this year.
June 11, 2012
Boehringer Ingelheim issued results from a phase III trial of afatinib as a first-line treatment for stage IIIb or IV non-small cell lung cancer (NSCLC). This randomized, open-label, comparative study, LUX-Lung 3, enrolled 345 patients with NSCLC harboring an epidermal growth factor receptor (EGFR) mutation. Subjects received afatinib (n≡230) or pemetrexed/cisplatin (n≡115). The study met its primary endpoint of progression-free survival (PFS). In the general population, afatinib-dosed subjects averaged an 11.1 month PFS versus 6.9 months PFS for subjects dosed with pemetrexed/cisplatin. The hazard ratio was 0.58 (95% CI: 0.43-0.78) (p≡0.0004). In the sub-population of patients with the most common EGFR mutations (Del19 and L858R), afatinib-dosed subjects had a PFS of 13.6 months versus 6.9 months in the chemotherapy arm. The hazard ratio in this patient subset was 0.47 (95% CI: 0.34-0.65) (p<0.0001). The most common adverse events were diarrhea, rash and paronychia.
July 11, 2011

Genta reported positive results from a phase II trial of Ganite for the treatment of non-Hodgkin's lymphoma, at the 43rd Annual Meeting of the American Society of Clinical Oncology. This trial, dubbed GaRD, enrolled 22 subjects who had failed prior treatment with rituximab. Subjects received Ganite in combination with rituximab and dexamethasone. Overall, 41% of the subjects achieved a major objective response, including 36% with complete or unconfirmed complete responses and 5% with a partial response. Two major responders had previously failed stem cell transplantation and both sustained remission 14+ and 18+ months after their last relapse. Six subjects achieved stable disease. Of all 22 Ganite treated subjects, 46% were alive at a median follow-up of 17+ months, and 7 were currently without evidence of disease. Based on the results Genta is planning a second phase II trial evaluating Ganite in combination with another standard cancer regimen.
Sanofi Aventis and Taiho reported positive results from a phase III trial of S-1 for the treatment of gastric cancer, at the 43rd Annual Meeting of the American Society of Clinical Oncology. This randomized trial, dubbed SPIRTS, enrolled 305 subjects in Japan. Subjects were randomized to receive either oral S-1 (40 mg/m2) twice daily for 28 days followed by a 14-day rest period, or oral S-1(40 mg/m2) twice daily for 21 days plus IV cisplatin on the eighth day of treatment, followed by the 14-day rest period. The primary endpoint was overall survival (OS). Secondary endpoints included Response Rate, Time to Treatment Failure (TTF) and toxicity. Results revealed overall survival with a two-year follow-up was significantly higher in the S-1/cisplatin combination arm compared to the S-1 alone arm, with a median rate of 13 months versus 11 months, respectively (p=0.036). The overall response rate was also significantly higher in the combination arm, with 54% of subjects in the S-1/cisplatin arm showing response to treatment compared with 31.1% with S-1 alone, p=0.001). In addition, S-1 with cisplatin significantly reduced the risk of death by 22.6% (HR: 0.774; 95% CI [0.608-0.985]) over S-1 alone. Several phase III trials of S-1 are underway in the United States.
Telik reported negative top-line results from a phase III trial of Telcyta for the treatment of non-small cell lung cancer (nsclc), at the 43rd Annual Meeting of the American Society of Clinical Oncology. This randomized, active control study, dubbed ASSIST-2, enrolled 530 subjects with advanced NSCLC whose disease had progressed following first-line platinum-based therapy and a second-line treatment. The trial was designed to compare Telcyta to gefitinib. Neither the primary endpoint, superiority in overall survival, nor the secondary endpoint, superiority in progression-free survival was reached. Median survival for the Telcyta arm was 4.6 months as compared with 6.1 months for the active control arm. Median progression-free survival was 2.2 months for the Telcyta arm as compared with 2.3 months for the gefitinib arm. Telcyta is currently in phase III trials for various other indications.

Cell Genesys announced positive long-term data from a phase II trial of GVAX for the treatment of operable pancreatic cancer. This trial enrolled 60 subjects who received GVAX after surgical resection of their tumor and adjuvant radiation and chemotherapy. GVAX was administered intradermally before and after standard post-operative adjuvant radiation therapy and 5-flourouracil chemotherapy. Treatment was administered at up to five doses, the first prior to adjuvant chemoradiotherapy, the next three following adjuvant therapy at approximately one-month intervals and the fifth as a booster injection six months later. Treatment was well tolerated through the study duration. The long-term survival results revealed a median survival of 26.8 months. GVAX is currently in phase III trials for the treatment of pancreatic cancer.
Sunesis reported interim results from two phase II trials of SNS-595 for the treatment of small cell lung cancer and non-small cell lung cancer. Both trials employed a two-stage design with an interim assessment between each stage. Objective response rate, as defined by RECIST (Response Evaluation Criteria in Solid Tumors) was the determination for advancing to stage two. All subjects received SNS-595 at the MTD of 48 mg/m2 every three weeks. The small cell cancer trial included a treatment-sensitive arm and a treatment-refractory arm. Nine out of eleven evaluable subjects in the treatment-sensitive arm had stable disease or objective response by the end of two cycles of treatment, which exceeded the pre-specified requirements for advancing to stage two. In the treatment-refractory arm, none of the 20 evaluable subjects reached objective response, although there were reports of stable disease. Based on the data, enrollment in this arm was discontinued. The non-small cell cancer trial enrolled 25 subjects who had previously failed first-line treatment. Although 50% had achieved stable disease or better, objective response rates were not observed. Based on these results, enrollment was discontinued in this trial. Sunesis plans to explore additional clinical evaluation of SNS-595 in combination with other anti-cancer agents in the treatment of non-small cell lung cancer pending the full evaluation of these results.
YM BioSciences released negative results from a phase III trial of tesmilifene combined with epirubicin/cyclophosphamide for the treatment of breast cancer. This trial, conducted under a Special Protocol Assessment by the FDA, enrolled 723 women with metastatic or recurrent breast cancer. Subjects received tesmilifene combined with epirubicin/cyclophosphamide or epirubicin/cyclophosphamide alone. A planned interim analysis was conducted to determine if there was a significant difference in overall survival rates between the two treatment groups, the primary endpoint. Review of the data found that such differences had not occurred and were unlikely to occur during the course of the trial. Based on this information, YM BioSciences terminated this trial.
November 6, 2006
Vion reported positive initial results from an ongoing phase II trial of Cloretazine for the treatment of relapsed or refractory small cell lung cancer. This trial enrolled 36 subjects who were placed into one of two treatment arms, a relapsed arm and a refractory arm. Subjects initially received 125 mg/m2 of Cloretazine weekly for three weeks, every six weeks. This dose was later reduced by protocol amendment to 100 mg/m2 weekly for three weeks, every six weeks, due to significant thrombocytopenia at the initial dose level. The most commonly reported serious adverse event was Grade 3 or 4 thrombocytopenia. Of the subjects on the relapsed arm, five had a partial response and two had stable disease. Of the subjects on the refractory arm, one subject had partial response and three had stable response. Vion is continuing to accrue subjects in both arms of the trial.
June 19, 2006
Novacea announced positive results of a phase I/II trial of DN-101 (calcitriol), for the treatment of non-small cell lung cancer (NSCLC).

Trial data indicated that all doses of the drug were well tolerated. In the first stage, tumor response rate across all subjects was 6.6%, with a median overall survival of 6.9 months. In the second stage, median overall survival appeared to be longer with weekly dosing of DN-101; data analysis was ongoing.
February 27, 2006
CEL-SCI has announced positive results of a long-term follow-up to a phase II trial of Multikine, for the treatment of head and neck cancer. Trial data indicated that the drug extended overall survival and increased regional tumor localization at 2 years, compared to literature-established values for approved therapies. This open-label study enrolled patients with advances primary head and neck cancer, who received the drug for 3 weeks, prior to surgery or surgery plus radiation/chemotherapy (standard therapy for the disease). The company anticipated initiating phase III trials of the drug in the near future.
CuraGen issued results of a phase II trial of velafermin, for the prevention of oral mucositis (OM) due to chemotherapy/radiotherapy. Results from the study indicated that the drug failed to meet its primary efficacy endpoint, failing to establish a significant, dose-dependent trend in rates of severe OM (p>0.05). Secondary data did yield positive activity for the lowest dose of the drug, significantly reducing incidence (p=0.031) and duration (p=0.037) of severe Grade 3 or 4 adverse events, and reducing the use of antibiotics, analgesics, antiemetics and total parenteral nutrition (TPN), and reduced rates of febrile neutropenia compared, to placebo. This multi-center, dose-ranging, randomized, double-blind, placebo-controlled study enrolled 212 patients, who received one of three doses of the drug (0.03 mg/kg, n=50; 0.1 mg/kg, n=56; and 0.2 mg/kg, n=55) or placebo (n=51). Based on these results, the company announced plans to initiate a phase II study of the low dose of the drug in Q2 2006, with preliminary results expected in Q3 2007.
Introgen reported positive results of a phase I/II trial of INGN 225, for the treatment of advanced small cell lung cancer in the journal Clinical Cancer Research. Trial data yielded a 62% objective tumor response rate for subjects receiving the drug in combination with chemotherapy, compared to a literature-established baseline of 5-25%. Further, 75% of subjects who experienced a p53 immune response (the drug's targeted mechanism of action) experienced objective clinical responses and increased overall survival. This open-label study enrolled second-line patients at the H. Lee Moffitt Cancer Center.
January 2, 2006
Pharmacyclics announced top-line results of a phase III trial of Xcytrin (motexafin), for the treatment of brain metastases in subjects with non-small cell lung cancer (NSCLC). Trial data failed to demonstrate significant improvement in time to neurological progression (15.4 months vs. 10.0 months for placebo; p=0.122). Further, no improvements were noted in overall survival or several other secondary endpoints, though reduction in steroid use trended positively. North American subjects did yield significant improvements (24.2 months vs. 8.8 months; p=0.004). This randomized, controlled study enrolled 554 patients across 94 site in North America, Europe and Australia.
November 28, 2005
Ariad Pharmaceuticals issued positive interim results of a phase Ib trial of an orally administered formulation of AP12573, their investigational mTOR inhibitor for the treatment of solid tumors. Data from the first 45 patients yielded a positive oral-dose tolerability profile across three daily dosing regimens: continuous daily dosing; dosing for 3 of every 4 weeks; and dosing for 4 of every 7 days. Maximum tolerated dose was reached in each of the first two regimens (10 mg and 15 mg daily, respectively), with oral mucositis noted as the dose limiting toxicity for each indication; dose-escalation was ongoing in the third group, and had reached doses of 40 mg daily on treatment days. This open-label dose- escalation had enrolled 58 subjects to date. The company announced plans to initiate investigation of additional regimens of the drug.
CuraGen and TopoTarget announced positive interim results of a phase I trial of PDX101, their histone deacetylase inhibitor for the treatment of solid tumors. Pharmacokinetic data yielded a dose-related absorption profile across trial regimens, and an elimination half-life of approximately 1 hour. Dose-proportional bioactivity was noted in histone hyperacetylation, which lasted 6-24 hours. Oral bioavailability was approximately 33%. No serious hematological toxicities were noted. This ongoing open-label dose-escalation study enrolled 42 patients with advanced refractory solid tumors, who received intravenous or orally available formulations PXD101 monotherapy. Based on these data, the company selected a dose of 1000 mg/m2 for use in upcoming phase II trials. Additional results of the study were to be presented at the annual meeting of the American Society of Hematology in December.
Point Therapeutics issued positive results of a phase II trial of talabostat for the treatment of non-small cell lung cancer (NSCLC). The drug produced an objective response rate (defined as a reduction in tumor size of at least 50%) of 11.9% (n=5/42); this included 3 partial responses and 2 ongoing complete responses (since March and April 2005). Median progression-free survival was 4.2 months, and median overall survival was 8.4 months; among the 31 patients enrolled in the study for at least a year, one-year survival rate was 48%. This open-label study enrolled 42 evaluable patient with relapsed or refractory NSCLC (64% second line, 36% third line or later; 75% failing a prior platinum/taxane regimen), who received talabostat in combination with docetaxel.

OXiGENE announced positive results of a phase Ib/II trial of their Combretastatin A4 Phosphate (CA4P), for the treatment of non-small cell lung cancer (NSCLC), at the 1st National Cancer Research Institute Cancer Conference in Birmingham, UK. Data from the first 12 subjects indicated that weekly drug administration produced a significant and sustained 40% reduction in tumor blood flow at 3 weeks, following radiation therapy. Median survival in subjects receiving weekly doses of the drug appeared to be longer than for subjects receiving the single-dose (11.6 months vs. 6.8 months), though these data were still preliminary. This ongoing open-label study enrolled 28 NSCLC patients, who received either a single-dose of CA4P (50 mg/m2) or weekly doses at the same dose level in combination with radiation therapy (27 Gray in 6 fractions) over 3 weeks.
August 15, 2005
Novelos has announced positive results of a phase I/II trial of NOV-002, for the treatment of non-small cell lung cancer. The drug is currently approved in Russia, where it is marketed as Glutomix. Intent-to-treat analysis indicated that 69% (11/16) of subjects receiving intravenous (IV) and subcutaneous (SC) NOV-002 in combination with chemotherapy achieved objective (complete or partial) tumor response, vs. 33% (5/15) receiving chemotherapy alone (p=0.044). Subjects receiving NOV-002 via IV and intramuscular (IM) injection plus chemotherapy experienced a non-significant 46% (6/13) objective response rate. The drug also produced improved tolerance of chemotherapy in both dosing groups, with 100% of the IV/SC and 85% of the IV/IM subjects completing 4 cycles of chemotherapy, vs. 50% of subjects receiving chemotherapy alone (p=0.004). This randomized, controlled study enrolled 44 patients, who received one of two regimens of NOV-002 (IV/SC or IV/IM) plus chemotherapy or chemotherapy alone for 6 months. The company announced plans to initiate phase II/III trials of the drug in 2006, based on these results.
July 18, 2005
Aphton reported positive results of a phase I trial of their anti-Lewis Y tumor-associated antigen monoclonal antibody IGN311, for the treatment of solid tumors. Data yielded a positive safety profile, with no adverse events reported for the low and middle dose regimens and 1 event (nausea & vomiting) noted in the high dose regimen. Pharmacokinetic results indicated a mean serum half-life of at least 20 days. Preliminary efficacy results demonstrated a reduction in the number of circulating Lewis-Y-positive tumor cells in those patients with detectable levels of these cells prior to treatment. This open-label dose- escalation study enrolled 12 subjects with Lewis Y positive epithelial tumors (breast, colorectal, gastric and pancreatic). Subjects received one of three doses of the drug (50 mg, n=3; 100 mg, n=3; or 200 mg, n=6) on days 1 and 15 of the study period. The company announced plans to initiate additional trials of the drug in the near future.

Cell Therapeutics issued positive preliminary results of a phase II trial of Xyotax (paclitaxel poliglumex), for the first-line treatment of ovarian cancer. Results from the induction phase of the study indicated that the drug produced an 85% complete response rate, with an additional 12% of subjects experiencing partial response. This 98% response rate was superior to a historical baseline response rate of 80%. This open-label study enrolled 82 patients with treatment naíve stage III/IV ovarian cancer, who received Xyotax in combination with carboplatin on day 1 of a 21 day cycle for 6 cycles.
GTx reported positive results of a phase IIb trial of Acapodene (toremifene citrate), for the prevention of prostate cancer. The drug was previously approved as a treatment for advanced breast cancer. Trial data indicated efficacy in the trial's primary endpoint, producing a 48% reduction in prostate cancer incidence at 12 months in the lowest dosing group, vs. placebo (p=0.45). The higher two dosing groups both produced non- significant reductions in disease incidence. This 4- arm, double blind, placebo-controlled study enrolled 514 patients with high grade prostatic intraepithelial neoplasia (a prostate cancer risk factor) across 64 US sites, who received one of 3 oral doses of Acapodene (20 mg, 40 mg or 60 mg) or placebo once daily for one year.
Regeneron announced preliminary results of a phase I trial of VEGF Trap, for the treatment of advanced cancers. The drug's overall safety profile was positive, with most toxicity issues observed to be mild to moderate, though occasional incidence of serious adverse reactions, including hypertension, was observed. Maximum tolerated dose had not yet been reached. Preliminary evidence of biological activity and efficacy were observed, with VEGF Trap administration producing rapid tumor vascular response and some evidence of efficacy (1 partial response, 2 minor responses and 1 stable disease). This open-label single-agent study had enrolled 27 patients to date, who received one of five dose levels of the drug.
Schering and Novartis reported preliminary results of their phase III "CONFIRM-1" trial of PTZ/ZK (vatalinib), for the treatment of colorectal cancer. Trial data failed to meet their primary endpoint, with the drug producing a non-significant 12% decrease in risk of disease progression (p=0.118), as assessed by central data review. Secondary efficacy was noted, with investigator review producing a 17% reduction in risk of progression (p=0.026); higher efficacy was also noted among subjects with high levels of serum lactate dehydrogenase. Overall tolerability was generally positive, with adverse events generally similar to other VEGF inhibitors. This randomized, double-blind, placebo-controlled study enrolled 1168 subjects, who received an oral dose of either 1250 mg PTK/ZK or placebo once daily, in combination with standard FOLFOX4 chemotherapy. The companies announced that these data, in combination with upcoming data from their CONFIRM-2 phase III trial, would form the basis of regulatory submission in early 2007.

April 25, 2005
Adventrx Pharmaceuticals reported results of a phase II trial of CoFactor (CH2FH4), in combination with 5- fluorouracil (5-FU), for the treatment of colorectal cancer. Toxicity and pharmacodynamic data indicated a positive toxicity profile based on a laboratory measures. Specifically, administration of CoFactor produced an increase producing increases in RBC folate pool expansion (form a mean baseline score of 533 ng/ml to a score of 1295 ng/ml following weekly dosing), urinary folate excretion (an indication of formaldehyde toxicity) showed a small decrease (from a baseline historical baseline of 5 ug/ml to a post-treatment mean of 3.7 ug/ml). These data support the use of CoFactor in combination with 5-FU to improve efficacy and reduce toxicity. This open-label study enrolled subjects with metastatic colorectal cancer, and was designed to investigate several laboratory measures of the toxicity associated with CoFactor administration and metabolism, in the hopes that the drug in combination with 5-FU will provide better efficacy and reduced toxicity, compared to standard therapy of 5-FU and leucovorin. The company announced that these data would serve to support upcoming phase IIb and III trials in the UK and the US.

Serious Grade III/IV adverse events occurred more often in cohort 1 (n=9) than cohort 2 (n=5). This two- armed open-label study enrolled 56 subjects with metastatic melanoma, who received MDX-1379 plus 3.0 mg/kg MDX-010 every 3 weeks (cohort 1; n=29), or MDX-1379 plus an initial 3.0 mg/kg dose of MDX-010, followed by 1.0 mg/kg every 3 weeks (cohort 2; n=27).
April 4, 2005
Ligand Pharmaceuticals reported negative results of a pair of phase III trials of Targretin (bexarotene), their retinoid X receptor modulator, for the first-line treatment of non-small cell lung cancer (NSCLC) in combination with chemotherapy. Both trials failed to meet the primary endpoint of improved overall survival, with no significant difference observed between subjects receiving Targretin combination therapy and subjects receiving chemotherapy alone. Further, neither trial produced evidence of efficacy in the secondary endpoint, improvements in Kaplan-Meier projected two-year survival. Both trials were dual arm studies which enrolled subjects across sites worldwide. In both studies, patients were randomized to receive either standard chemotherapy (cisplatin/vinorelbine in the first, carboplatin/paclitaxel in the second) alone or in combination with oral doses of Targretin. Based on these results, Ligand announced plans to shift the development focus for Targretin to second- and third-line NSCLC indications.
December 6, 2004
Genentech reported positive results of a phase III study of Avastin (bevacizumab), their monoclonal antibody approved for the treatment of non-small cell lung cancer, for the treatment of colorectal cancer. Interim results indicated that the addition of Avastin to a standard chemotherapy regimen produced a 26% reduction in the risk of death, compared to chemotherapy alone. Furthermore, the drug produced a 17% improvement in median survival time (12.5 vs. 10.7 months). This randomized, controlled, multicenter trial enrolled 829 patients with advanced refractory colorectal cancer, who received a standard FOLFOX4 chemotherapy regimen (oxaliplatin/5-FU/leucovorin) with or without Avastin. Genentech announced that they planned to discuss filing of an sBLA with the FDA based upon these results.
Genmab has announced positive preliminary results from a phase I/II trial of HuMax-EGFr, for the treatment of head and neck cancer. The trial used two neural imaging techniques to examine tumor size and function following 4 weekly doses of the drug. The first technique, which measured disease state by metabolic activity, found that of the 15 subjects evaluable by this method, 6 showed a partial metabolic response (PMR) and 3 patients out of the 15 showed a stable metabolic disease (SMD). All patients showing response were in one of the three highest dose cohorts, and all subjects in the two highest dose cohorts experienced either PMR or SMD. The second imaging technique, which measured tumor size, found that of the 16 patients evaluable by this method, 2 showed a partial response (PR) and 8 showed stable disease (SD). All responses occurring in one of the four highest dose groups, and six out of 7 patients in the two highest groups obtained a PR or SD. This open-label study enrolled a total of 17 subjects, who were randomized to receive a single-treatment of one of six doses of the drug (0.15, 0.5, 1, 2, 4 or 8 mg/kg), followed by a 28 day safety washout and subsequent treatment once weekly for 4 weeks at the same dose. The company announced that they expected additional data from the trial in 2005.
Point Therapeutics has announced positive interim results of a phase II trial of talabostat (PT-100), for the treatment of refractory non-small cell lung cancer (NSCLC).

Additional efficacy was observed in the secondary endpoint, with a median time to tumor progression of 24 weeks, compared to a historical baseline of 14. This open-label study plans to enroll a total of 41 patients with unresectable NSCLC, all of whom will receive daily oral talabostat for 2 weeks, following a standard dose of the chemotherapeutic taxotere. Achievement of this interim milestone allows the company to continue enrolling patients up to the full planned cohort size.
November 8, 2004
Biomira and Merck have announced positive results of a phase II b trial of BLP 25, their investigational liposomal vaccine for the treatment of non-small cell lung cancer (NSCLC). Trial data demonstrated that the drug produced significant increases in median patient survival time, including a 4.4 month extended benefit in patients receiving L-BLP25 after having achieved either stable disease or a response to first line chemotherapy. Overall median survival for the cohort receiving the vaccine was 17.4 months, versus 13 months for the control group. Benefit was also seen in the number of patients achieving two year survival in the vaccine cohort than in the standard control group (43.2% vs., 28.9%), and in maintenance of quality of life measures. This randomized, standard-therapy-controlled study enrolled 171 first-line-relapsed or refractory NSCLC patients, who received a single low-dose of intravenous cyclophosphamide three days prior to the first vaccination dose; vaccinations were given weekly for the first eight weeks and at six-week intervals thereafter. Quality of life and clinical assessments took place at Week 4, Week 8 and then at 12-week intervals for the remainder of the trial. The companies announced plans to continue development of the drug in additional trials.

ImmunoGen reported results of a phase I dose-escalation study of HuC242-DM1/SB-408075 (cantuzumab mertansine) in subjects with refractory cancer that expresses the CanAg antigen. Dosing was increased in each new cohort of subjects until dose-limiting toxicity was demonstrated. Based on the results, the recommended dose for cantuzumab mertansine is 235 mg/m2 when administered once every three weeks. In addition, one subject with colon cancer exhibited DM1 localization at the tumor site 24 hours after administration of the drug. Furthermore, this subject had a reduction in lung metastases after two and four courses of cantuzumab mertansine
Introgen reported positive results from a phase II trial investigating Advexin (p53 therapy) for the treatment of non-small cell lung cancer. Results showed that approximately 60% of subjects' primary tumors regressed or disappeared, as assessed by both biopsies and by CT scans three months after treatment. Administration of the drug did not appear to increase the side effect caused by radiation treatment. The study enrolled subjects with non-metastatic non-small cell lung cancer who were ineligible to receive alternative treatments. Advexin was administered via injection into tumors at a range of doses over one month.
Rational Therapeutics reported positive results from two phase II trials investigating gemcitabine with cisplatin as a combination therapy in the treatment of relapsed ovarian cancer. In the first study, results showed that the combination therapy achieved a 70% response rate, with more than 20% of subjects achieving complete remission. Subjects who demonstrated the most tumor response also showed the most sensitivity to the drug in ex-vivo laboratory assays. Out of 27 subjects, there were 26% (7) complete and 44% (12) partial responses. Subjects received cisplatin (30 mg/m2) plus gemcitabine (600-750 mg/m2) intravenously. Seventeen subjects underwent ex vivo analyses for correlation with clinical response. The second study enrolled 36 platinum and paclitaxel resistant subjects. Of the 15 subjects that responded, 11 were partial clinical responses and 4 were complete clinical responses. Gemcitabine (750 mg/m2) was administered intravenously over 30 min followed by cisplatin (30 mg/m2).
July 8, 2002
Positive follow-up data was obtained from a phase I/II trial of Cell Genesys' Gvax lung cancer vaccine. The multicenter trial, which evaluated vaccine made directly from subject tumor biopsies, included non-small cell lung cancer (NSCLC) subjects with either advanced heavily pretreated disease or early stage disease with high risk of relapse after surgery. Data for 33 advanced disease subjects showed a median survival of 8.0 months, compared to the reported 5.7-7.0 months for docetaxel, the approved second-line chemotherapy for such patients, or 4.6 months for best supportive care. Two of the three subjects with advanced disease who achieved a durable complete response had a lung cancer subtype referred to as bronchoalveolar carcinoma (BAC); this diagnosis was found to be the only identifiable predictor of increased survival in the advanced subject group. Based on the study data, the company plans to focus the next trials of the vaccine on BAC, as opposed to initiating a trial for all NSCLC types.
