PURPOSE Antiangiogenic agents combined with chemotherapy have efficacy in the treatment of unresectable malignant pleural mesothelioma (MPM). Cediranib (AstraZeneca, Cheshire, United Kingdom), a vascular endothelial growth factor receptor and platelet-derived growth factor receptor inhibitor, demonstrated therapeutic potential in a prior phase I trial. We evaluated a phase II trial for efficacy. PATIENTS AND METHODS SWOG S0905 (ClinicalTrials.gov identifier: NCT01064648 ) randomly assigned cediranib or placebo with platinum-pemetrexed for six cycles followed by maintenance cediranib or placebo in unresectable chemotherapy-naïve patients with MPM of any histologic subtype. Primary end point was Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 progression-free survival (PFS). Secondary end points included overall survival, PFS by modified RECIST v1.1, response (modified RECIST and RECIST v1.1), disease control, and safety/toxicity. The trial was designed to detect a difference in RECIST v1.1 PFS at the one-sided 0.1 level using a stratified log-rank test. RESULTS Ninety-two eligible patients were enrolled (75% epithelioid and 25% biphasic or sarcomatoid). The cediranib arm had more grade 3 and 4 diarrhea, dehydration, hypertension, and weight loss. Cediranib improved PFS by RECIST v1.1 (hazard ratio, 0.71; 80% CI, 0.54 to 0.95; P = .062; 7.2 months v 5.6 months) and increased modified RECIST v1.1 response (50% v 20%; P = .006). By modified RECIST v1.1, cediranib numerically increased PFS (hazard ratio, 0.77; 80% CI, 0.59 to 1.02; P = .12; median, 6.9 months v 5.6 months). No significant difference in overall survival was observed. CONCLUSION The addition of cediranib to platinum-pemetrexed improved PFS by RECIST v1.1 and response rate by modified RECIST in patients with unresectable MPM. Whereas adding antiangiogenics to chemotherapy has been a successful strategy for some patients, the cediranib toxicity profile and small incremental survival benefit precludes additional development in MPM.

Malignant pleural mesothelioma (MPM) is the most common tumor of the pulmonary pleura. It is a rare and aggressive malignancy, generally associated with continuous occupational exposure to asbestos. Only a multimodal-approach to treatment, based on surgical resection, chemotherapy and/or radiation, has shown some benefits. However, the survival rate remains low. Nimotuzumab (h-R3), an anti-EGFR (epidermal growth factor receptor) humanized antibody, is proposed as a promising agent for the treatment of MPM. The aim of this research was to implement a procedure for nimotuzumab radiolabeling to evaluate its biodistribution and affinity for EGF (epidermal growth factor) receptors present in a mesothelioma xenograft. Nimotuzumab was radiolabeled with 67Ga; radiolabel efficiency, radiochemical purity, serum stability, and biodistribution were evaluated. Biodistribution and tumor uptake imaging studies by microSPECT/CT in mesothelioma xenografts revealed constant nimotuzumab uptake at the tumor site during the first 48 h after drug administration. In vivo studies using MPM xenografts showed a significant uptake of this radioimmunoconjugate, which illustrates its potential as a biomarker that could promote its theranostic use in patients with MPM.

Purpose This multicenter, phase II clinical study was conducted to evaluate the activity of the combination of pemetrexed and carboplatin in patients with malignant pleural mesothelioma (MPM). Patients and Methods Chemotherapy-naive patients with measurable disease and adequate organ function, who were not eligible for curative surgery, received pemetrexed 500 mg/m2 and carboplatin area under the plasma concentration-time curve of 5 mg/mL/min, administered intravenously every 21 days. All patients received folic acid and vitamin B12 supplementation. Pemetrexed was provided within the Expanded Access Program. Results A total of 102 patients were enrolled. An objective response was achieved in 19 patients (two complete and 17 partial responses), for a response rate of 18.6% (95% CI, 11.6% to 27.5%). Forty-eight patients (47.0%; 95% CI, 37.1% to 57.2%) had stable disease after treatment. Overall, 67 patients (65.7%) achieved disease control (95% CI, 55.6% to 74.8%). Median time to progression was 6.5 months; median overall survival time was 12.7 months. Compliance to treatment was excellent, with a relative dose-intensity of 97% for pemetrexed and 98% for carboplatin. Toxicity was mild, with grade 3 or 4 neutropenia occurring in 9.7% of total cycles and grade 3 or 4 anemia occurring in 3.5% of total cycles. Nonhematologic toxicity was negligible. Conclusion Treatment with pemetrexed and carboplatin was active and well tolerated in patients with MPM. Disease control rate, time to disease progression, and overall survival were similar to the results achieved with the standard regimen of pemetrexed and cisplatin, suggesting that the carboplatin combination could be an alternative option for these patients.
