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.

YM Biosciences released positive results from two phase II trials of nimotuzumab for the treatment of brain metastases and brain cancer. The first trial was a randomized, open, controlled trial in 30 subjects diagnosed with advanced non-small cell lung cancer (NSCLC) and unresectable brain metastases. The subjects received nimotuzumab (200 mg administered as weekly intravenous infusions over weeks 1-6) plus palliative radiation (40 Gy in four weeks) or palliative radiation alone. The primary endpoint was disease control rate (DCR- Complete Response + Partial Response + Stable Disease). Data are from the first 21 subjects. DCR was 91.6% for the nimotuzumab plus radiation arm compared to 44.4% for the radiation alone arm. Subjects treated with the combination had a median survival of 7 months compared to the control group for whom the median survival was 2.47 months (p= 0.0039). The second trial was a randomized, double blind phase II/III trial in 80 subjects with newly diagnosed high-grade glioma. Following biopsy, partial or total resection of the tumor, the subjects received six weekly infusions of placebo or nimotuzumab (200 mg) while also receiving radiotherapy, followed by a maintenance dose of nimotuzumab or placebo every 21 days. The treatment duration was one year. Results are from the first 65 enrolled subjects. The median survival time for the subjects treated with nimotuzumab plus radiotherapy was 16.43 months, while the median survival time for the placebo arm was 10.49 months. Nimotuzumab was well tolerated in both studies.

Boehringer Ingelheim released positive results from a phase II trial of BIBF 1120 for the treatment of non-small cell lung cancer. This double blind, randomized study enrolled 73 subjects with advanced and metastatic NSCLC who had received at least one platinum-based therapy, and had an ECOG score of 02. The subjects received BIBF-1120 administered twice daily (150 mg or 250 mg). The primary endpoints were progression-free survival (PFS) and objective tumor response. Secondary endpoints included overall survival (OS) and safety. BIBF 1120 showed a substantial clinical effect in a subset of 57 subjects with ECOG scores of 0 or 1. The data showed that the median OS and PFS of this group were 9.5 and 2.9 months, respectively, compared with 5.5 and 1.7 months in the overall study population. This subset also had a higher stable disease rate of 59%, compared with the overall study population. Disease control was achieved in 48% of subjects and no difference in efficacy between the two dose treatment arms was observed. The 250 x 2 mg dose, with the option of reduction to 150 x 2 mg, was considered the recommended dose for monotherapy. BIBF 1120 was well tolerated, with the most frequent adverse events including mild-to-moderate nausea, diarrhea and vomiting. Based on the results Boehringer Ingelheim plans to move forward with the development of BIBF 1120.

Reported data is from 30 evaluable subjects with stage IIIB or IV NSCLC who received XL647 administered orally, at a dose of 350 mg on days 1-5 of repeated 14-day cycles. To date 8 partial responses and 11 stable disease had been reported. Of the 8 subjects who experienced partial responses, 4 had epidermal growth factor receptor (EGFR) exon 19 deletions, 1 had an EGFR L858R mutation, and 3 were EGFR wild-type. All 6 subjects with EGFR-activating mutations demonstrated clinical benefit, with 5 partial response and 1 stable disease. Treatment was generally well tolerated. Additional phase II trials are currently underway.
Kosan issued positive results from a phase I trial of alvespimycin for the treatment of breast and ovarian cancer. This trial enrolled 25 subjects who received one-hour weekly intravenous infusion of 60, 80 or 100 mg/m2 alvespimycin administered along with the standard dose of trastuzumab. The subjects were assessed every four weeks for toxicity and every eight weeks for response, as measured by RECIST criteria and tumor markers. Clinical benefit was observed in 42% of evaluable subjects with HER2-positive metastatic breast cancer. This included one subject with complete resolution of lung metastases, one subject with a 10% reduction in tumor mass and tumor necrosis, one subject with a partial response after 2 cycles and five subjects with stable disease. Of the subjects with ovarian cancer, there was one subject with a near complete resolution of ascites and left pleural effusion at the end of cycle 2. Based on the results, Kosan plans to expand the phase I trial to add weekly dosing with paclitaxel. Phase II trials are planned for Q4 of 2007.
Merck reported positive long-term results from a phase II trial of Stimuvax for the treatment of non-small cell lung cancer (NSCLC). This study enrolled 171 subjects with stage IIIB/IV nsclc with stable or responding disease after any first-line chemotherapy with or without radiotherapy. The subjects were stratified by disease stage than randomized to receive Stimuvax plus best supportive care (BSC) or BSC alone. The subjects in the Stimuvax arm received a single intravenous dose of cyclophosphamide 300mg/m2 followed by 8 weekly subcutaneous immunizations with Stimuvax (1,000 mg). Although the overall study results did not reach statistical significance, the subjects with stage IIIB cancer receiving Stimuvax showed a median survival of 30.6 months versus 13.3 months in the control group. At the three year follow-up, 49% of the subjects who were treated with Stimuvax were still alive versus 27% treated with BSC alone, representing a 45% reduction in mortality. Based on the results, Merck is currently conducting a phase III trial of Stimuvax for the treatment of stage IIIA or IIIB non-small cell lung cancer.
Pfizer released positive preliminary results from a phase II trial of sunitinib for the treatment of non-small cell lung cancer (NSCLC).

Telik announced positive results from a phase II trial of Telcyta in combination with carboplatin and paclitaxel for the treatment of non-small cell lung cancer. This dose-ranging trial enrolled 129 subjects with Stage IIIB or IV non-small cell lung cancer. Subjects received standard doses of carboplatin and paclitaxel and one of four doses of Telcyta (400, 500, 750 or 1,000 mg/m2) for a course of four to six cycles. Subjects with objective responses or stable disease following completion of combination therapy could elect to receive every three week maintenance cycles of Telcyta as monotherapy until disease progression. The primary endpoints for the intent-to-treat population included safety, objective response and disease stabilization rates, progression-free survival and overall survival. The primary endpoints in the Telcyta maintenance therapy group included safety, progression-free survival and overall survival. The overall objective response rate in the intent-to-treat population was 34% including one complete response. Disease stabilization was seen in 43%, for an overall disease stabilization rate of 77%. Median progression-free survival was 4.9 months, and the overall median survival was 9.6 months. Objective responses or stable disease at the completion of combination therapy was seen in 77% of the enrolled subjects. Half of the subjects received Telcyta maintenance therapy and half did not. Median progression-free survival for those on maintenance therapy was 6.9 months, compared with 4.2 months for those not on maintenance therapy (p< 0.0001, HR 0.36). Overall median survival for the Telcyta-treated subjects was 14.2 months compared with 8.4 months without Telcyta maintenance therapy (p= 0.0003, HR 0.40). Treatment was well tolerated at all doses with no unexpected toxicities. Based on the results Telik plans to move the development of Telcyta forward.
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.

Pharmacyclics reported results from an international, randomized controlled, phase III clinical trial investigating using Xcytrin on non-small cell lung cancer. The researchers concluded that when combined with whole brain radiation therapy (WBRT), Xcytrin significantly slowed the time to neurological progression and decreased deaths due to brain tumor in subjects with brain metastases from lung cancer. There was a significant improvement among the 401 intent-to-treat subject population, with the median time to neurologic progression at 3.8 months with WBRT alone versus 4.3 months with WBRT and Xcytrin. Among lung cancer patients, the median time to neurological progression was 3.7 months with WBRT alone versus 5.5 months with WBRT and Xcytrin. There was a significant reduction in brain tumor deaths among lung cancer subjects with 51% dying after receiving WBRT alone versus 32.2% after receiving WBRT and Xcytrin. Additionally, positive interim results were also reported for Xcytrin in an ongoing phase II clinical trial studying primary brain tumors (glioblastoma multiforme, or GBM).
