Abstract

Joining cetuximab, sorafenib, afatinib, intedanib, and crizotinib in phase III development for non-small cell lung cancer (NSCLC) are ramucirumab (developed by ImClone, a subsidiary of Lilly), necitumumab (developed by ImClone and Bristol-Myers Squibb), and tivantinib (ARQ 197, developed by ArQule and Daiichi Sankyo).

Necitumumab is a second-generation anti-EGFR monoclonal antibody (mAb) similar to cetuximab. Enrollment has been stopped in one of two necitumumab phase III trials because of safety concerns.

Ramucirumab is an anti-VEGFR2 mAb targeting the same pathway as bevacizumab. Although the phase II safety data for ramucirumab appear better than the data for necitumumab, fewer phase III data are available.

Tivantinib is a highly selective, orally available MET tyrosine kinase inhibitor. MET is overexpressed in 61% of NSCLC cases. Although tivantinib is the last of the three agents discussed here to enter phase III, its phase II results are the most robust.

Notes

  1. The inThought Approvability Index (IAI) is a dynamic tool that assesses the progress of a drug candidate through clinical development, evaluating the strength of clinical data and trial design, benchmarked against historical parameters and the likelihood of maintaining forward momentum. Points are assigned for specific line items relating to safety, efficacy, and other factors in each phase of clinical development. Possible points total 100 upon drug approval and are allocated in each phase according to the historical approval rate of similar drugs, such that the current points of a drug relate to its probability of approval. In addition, a letter grade is assigned and reflects the momentum of a drug candidate in its current phase, with ‘A’ indicating significantly above average/likely to progress, ‘C’ indicating average, and ‘F’ indicating significantly below average/unlikely to progress.
