RRx-001 is a cysteine-directed anticancer alkylating agent with activity in a Phase II study in platinum refractory small cell lung cancer. Here, we describe the design of REPLATINUM, an open-label, Phase III trial. 120 patients with previously platinum-treated small cell lung cancer in third line will be randomized 1:1 to receive RRx-001 followed by four cycles of a platinum doublet, and then alternating cycles of RRx-001 and single agent platinum until progression versus four cycles of a platinum doublet. At radiologic progression on the platinum doublet, patients may cross over to the RRx-001 arm. Primary objective: to demonstrate superior progression-free survival in the RRx-001 population. Secondary objectives: to demonstrate superiority for overall survival and objective response rate. Clinical Trial registration: NCT03699956

In this phase III randomized study, 124 evaluable patients with unresectable non-small-cell lung cancer (NSCLC) were randomized to vindesine v cisplatin (120 mg/m2) plus vindesine v cisplatin (60 mg/m2) plus vindesine plus mitomycin C. The objective response rate for cisplatin and vindesine was 27% v 20% for cisplatin, vindesine, and mitomycin C, and 14% for vindesine alone (P = .25 for cisplatin and vindesine v vindesine). The percentage of patients having stable disease (no progression for a minimum of 3 months) was 20% (cisplatin and vindesine), 27% (cisplatin, vindesine, and mitomycin C), and 26% (vindesine alone), respectively. The median survival time for vindesine was 18 weeks, compared with 26 weeks for cisplatin and vindesine and 17 weeks for cisplatin, vindesine, and mitomycin C. Overall survival was not statistically different for cisplatin plus vindesine v vindesine (P = .65). There was no evidence for improved duration of remission or survival of responders with the cisplatin (120 mg/m2) and vindesine arm. This study failed to demonstrate sufficient therapeutic benefit for cisplatin and vindesine (+/- mitomycin C) compared with single-agent vindesine to justify the increased cost and toxicity of these combination regimens.

Purpose Erlotinib is a potent reversible HER1/epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor with single-agent activity in patients with non–small-cell lung cancer (NSCLC). Erlotinib was combined with chemotherapy to determine if it could improve the outcome of patients with NSCLC. Patients and Methods TRIBUTE randomly assigned patients with good performance status and previously untreated advanced (stage IIIB/IV) NSCLC to erlotinib 150 mg/d or placebo combined with up to six cycles of carboplatin and paclitaxel, followed by maintenance monotherapy with erlotinib. Random assignment was stratified by stage, weight loss in the previous 6 months, measurable disease, and treatment center. The primary end point was overall survival (OS). Secondary end points included time to progression (TTP), objective response (OR), and duration of response. Results There were 1,059 assessable patients (526 erlotinib; 533 placebo). Median survival for patients treated with erlotinib was 10.6 v 10.5 months for placebo (hazard ratio, 0.99; 95% CI, 0.86 to 1.16; P = .95). There was no difference in OR or median TTP. Patients who reported never smoking (72 erlotinib; 44 placebo) experienced improved OS in the erlotinib arm (22.5 v 10.1 months for placebo), though no other prespecified factors showed an advantage in OS with erlotinib. Erlotinib and placebo arms were equivalent in adverse events (except rash and diarrhea). Conclusion Erlotinib with concurrent carboplatin and paclitaxel did not confer a survival advantage over carboplatin and paclitaxel alone in patients with previously untreated advanced NSCLC. Never smokers treated with erlotinib and chemotherapy seemed to experience an improvement in survival and will undergo further investigation in future randomized trials.

Purpose To compare the efficacy and safety of weekly paclitaxel in combination with carboplatin administered every 4 weeks to the standard regimen of paclitaxel and carboplatin administered every 3 weeks for the treatment of patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods Four hundred forty-four patients with previously untreated stage IIIB/IV NSCLC were randomly assigned to either arm 1 (n = 223), paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin area under the curve (AUC) = 6 mg/mL · min on day 1 of each 4 week cycle, or arm 2 (n = 221), paclitaxel 225 mg/m2 and carboplatin AUC = 6 on day 1 of each 3-week cycle. After four cycles of therapy, patients in both treatment arms were eligible to continue weekly paclitaxel (70 mg/m2, 3 of 4 weeks) as maintenance therapy until unacceptable toxicity or disease progression. Results The objective response rate was 27.6% for arm 1 and 19.2% for arm 2. Median time to progression (TTP) was 18.4 and median survival (MS) was 38.6 weeks for arm 1. For arm 2, the median TTP and MS were 16.7 weeks and 42.9 weeks respectively. Grade 3/4 anemia was more common with arm 1, although grade 2/3 neuropathy and arthralgia were less common. The remainder of the toxicities were similar between the two arms. Conclusion All efficacy parameters were similar between the two treatment arms. The favorable nonhematologic toxicity profile of arm 1 makes this an alternative treatment option for patients with advanced NSCLC.

PurposeThis study evaluated the efficacy and safety of pemetrexed, carboplatin, and bevacizumab followed by maintenance pemetrexed and bevacizumab in patients with chemotherapy-naive stage IIIB (effusion) or stage IV nonsquamous non–small-cell lung cancer (NSCLC).Patients and MethodsPatients received pemetrexed 500 mg/m2, carboplatin area under the concentration-time curve of 6, and bevacizumab 15 mg/kg every 3 weeks for six cycles. For patients with response or stable disease, pemetrexed and bevacizumab were continued until disease progression or unacceptable toxicity.ResultsFifty patients were enrolled and received treatment. The median follow-up was 13.0 months, and the median number of treatment cycles was seven (range, one to 51). Thirty patients (60%) completed ≥ six treatment cycles, and nine (18%) completed ≥ 18 treatment cycles. Among the 49 patients assessable for response, the objective response rate was 55% (95% CI, 41% to 69%). Median progression-free and overall survival rates were 7.8 months (95% CI, 5.2 to 11.5 months) and 14.1 months (95% CI, 10.8 to 19.6 months), respectively. Grade 3/4 hematologic toxicity was modest—anemia (6%; 0), neutropenia (4%; 0), and thrombocytopenia (0; 8%). Grade 3/4 nonhematologic toxicities were proteinuria (2%; 0), venous thrombosis (4%; 2%), arterial thrombosis (2%; 0), fatigue (8%; 0), infection (8%; 2%), nephrotoxicity (2%; 0), and diverticulitis (6%; 2%). There were no grade 3 or greater hemorrhagic events or hypertension cases.ConclusionThis regimen, involving a maintenance component, was associated with acceptable toxicity and relatively long survival in patients with advanced nonsquamous NSCLC. These results justify a phase III comparison against the standard-of-care in this patient population.

Purpose Erlotinib is a potent inhibitor of the epidermal growth factor receptor tyrosine kinase, with single-agent antitumor activity. Preclinically, erlotinib enhanced the cytotoxicity of chemotherapy. This phase III, randomized, double-blind, placebo-controlled, multicenter trial evaluated the efficacy and safety of erlotinib in combination with cisplatin and gemcitabine as first-line treatment for advanced non–small-cell lung cancer (NSCLC). Patients and Methods Patients received erlotinib (150 mg/d) or placebo, combined with up to six 21-day cycles of chemotherapy (gemcitabine 1,250 mg/m2 on days 1 and 8 and cisplatin 80 mg/m2 on day 1). The primary end point was overall survival (OS). Secondary end points included time to disease progression (TTP), response rate (RR), duration of response, and quality of life (QoL). Results A total of 1,172 patients were enrolled. Baseline demographic and disease characteristics were well balanced. There were no differences in OS (hazard ratio, 1.06; median, 43 v 44.1 weeks for erlotinib and placebo groups, respectively), TTP, RR, or QoL between treatment arms. In a small group of patients who had never smoked, OS and progression-free survival were increased in the erlotinib group; no other subgroups were found more likely to benefit. Erlotinib with chemotherapy was generally well tolerated; incidence of adverse events was similar between arms, except for an increase in rash and diarrhea with erlotinib (generally mild). Conclusion Erlotinib with concurrent cisplatin and gemcitabine showed no survival benefit compared with chemotherapy alone in patients with chemotherapy-naïve advanced NSCLC.

Pemetrexed (Alimta, Eli Lilly) is a multi-targeted anti-folate originally approved for its use in malignant mesothelioma. Based on results from phase III clinical investigations, it is now approved for use as a single agent in the second-line setting and in combination with platinum therapy in the first-line setting for advanced non-small cell lung cancer. It is also under investigation in earlier stages of non small cell lung cancer including in the adjuvant setting and with radiation. It has shown to be particularly efficacious for non-squamous histology and is well tolerated. Toxicity includes, but is not limited to hematologic toxicity and gastrointestinal toxicity, which are minimized by vitamin B12 and folic acid supplementation. Recent analyses also suggest cost-effectiveness of this agent in patient with advanced, non-squamous cell non-small cell lung cancer.

PURPOSE A phase III randomized trial in patients with advanced non-small-cell lung cancer (NSCLC) was performed to determine if the addition of ifosfamide to moderate-dose cisplatin and carboplatin improved response rate (primary end point) and survival. PATIENTS AND METHODS A total of 529 patients were randomized to receive a combination of moderate-dose carboplatin (200 mg/m2 intravenously [i.v.] on day 1) and cisplatin (30 mg/m2 i.v. on days 2 and 3) with (CCI arm) or without (CC arm) ifosfamide (1.5 g/m2 i.v. on days 1 to 3). There were 248 eligible patients on the CC arm and 257 on the CCI arm, with 220 and 238 patients assessable for response, respectively. All but 23 had stage IV disease with pleural effusion. RESULTS There was a 16% objective response (OR) rate to CC and a 31% OR rate to CCI. That observed difference was highly statistically significant (P < 0.001). Duration of response and survival were not statistically different between arms. The CCI regimen was associated with significantly more acute toxicities: emesis, alopecia, leukopenia, and thrombocytopenia. The frequency of chronic renal, auditive, and peripheral neurologic toxicity was low in both arms (4.6% and 6.6%, respectively, after six courses of chemotherapy). The relative dose-intensity (RDI) of the CCI arm was significantly lower than that of the CC arm. CONCLUSION The addition of ifosfamide to moderate-dose cisplatin and carboplatin significantly improves the antitumoral response rate, but has no apparent effect an survival in advanced NSCLC.

Purpose Although current treatment options for metastatic non–small-cell lung cancer (NSCLC) rely on cisplatin-based chemotherapy, individualized approaches to therapy may improve response or reduce unnecessary toxicity. Excision repair cross-complementing 1 (ERCC1) has been associated with cisplatin resistance. We hypothesized that assigning cisplatin based on pretreatment ERCC1 mRNA levels would improve response. Patients and Methods From August 2001 to October 2005, 444 stage IV NSCLC patients were enrolled. RNA was isolated from pretreatment biopsies, and quantitative real-time reverse transcriptase PCR assays were performed to determine ERCC1 mRNA expression. Patients were randomly assigned in a 1:2 ratio to either the control or genotypic arm before ERCC1 assessment. Patients in the control arm received docetaxel plus cisplatin. In the genotypic arm, patients with low ERCC1 levels received docetaxel plus cisplatin, and those with high levels received docetaxel plus gemcitabine. The primary end point was the overall objective response rate. Results Of 444 patients enrolled, 78 (17.6%) went off study before receiving one cycle of chemotherapy, mainly due to insufficient tumor tissue for ERCC1 mRNA assessment. Of the remaining 346 patients assessable for response, objective response was attained by 53 patients (39.3%) in the control arm and 107 patients (50.7%) in the genotypic arm (P = .02). Conclusion Assessment of ERCC1 mRNA expression in patient tumor tissue is feasible in the clinical setting and predicts response to docetaxel and cisplatin. Additional studies are warranted to optimize methodologies for ERCC1 analysis in small tumor samples and to refine a multibiomarker profile predictive of patient outcome.

Purpose Figitumumab (CP-751,871), a fully human immunoglobulin G2 monoclonal antibody, inhibits the insulin-like growth factor 1 receptor (IGF-1R). Our multicenter, randomized, phase III study compared figitumumab plus chemotherapy with chemotherapy alone as first-line treatment in patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods Patients with stage IIIB/IV or recurrent NSCLC disease with nonadenocarcinoma histology received open-label figitumumab (20 mg/kg) plus paclitaxel (200 mg/m2) and carboplatin (area under the concentration-time curve, 6 mg · min/mL) or paclitaxel and carboplatin alone once every 3 weeks for up to six cycles. The primary end point was overall survival (OS). Results Of 681 randomly assigned patients, 671 received treatment. The study was closed early by an independent Data Safety Monitoring Committee because of futility and an increased incidence of serious adverse events (SAEs) and treatment-related deaths with figitumumab. Median OS was 8.6 months for figitumumab plus chemotherapy and 9.8 months for chemotherapy alone (hazard ratio [HR], 1.18; 95% CI, 0.99 to 1.40; P = .06); median progression-free survival was 4.7 months (95% CI, 4.2 to 5.4) and 4.6 months (95% CI, 4.2 to 5.4), respectively (HR, 1.10; P = .27); the objective response rates were 33% and 35%, respectively. The respective rates of all-causality SAEs were 66% and 51%; P < .01). Treatment-related grade 5 adverse events were also more common with figitumumab (5% v 1%; P < .01). Conclusion Adding figitumumab to standard chemotherapy failed to increase OS in patients with advanced nonadenocarcinoma NSCLC. Further clinical development of figitumumab is not being pursued.
