A Dose Escalation Study of L-DOS47 in Recurrent or Metastatic Non-Squamous NSCLC

A Phase I, Open Label, Dose Escalation Study of Immunoconjugate L-DOS47 in Combination With Pemetrexed/Carboplatin in Patients With Stage IV (TNM M1a and M1b) Recurrent or Metastatic NSCL Lung Cancer

The primary purpose of this research study is to evaluate how safe, how well tolerated and how effective a range of doses of L-DOS47 in combination with standard doublet therapy of pemetrexed/carboplatin in patients with Stage IV (TNM M1a and M1b) recurrent or metastatic non-squamous Non-Small Cell Lung Cancer.

It is planned that patients will receive 4 cycles of combination treatment with L-DOS47 + pemetrexed/carboplatin. Patients who have not progressed following the 4 cycles of combination treatment and who have not experienced unacceptable toxicity will have the opportunity to continue to receive L-DOS47 treatment for as long as there is clinical benefit and it is well-tolerated, in the opinion of the Investigator, until disease progression. Patients who are unable to complete 4 cycles of L-DOS47 + pemetrexed/carboplatin combination treatment due to pemetrexed/carboplatin toxicity will have the opportunity to continue receiving L-DOS47 treatment following discontinuation of pemetrexed/carboplatin, for as long as there is clinical benefit and it is well-tolerated, in the opinion of the Investigator, until disease progression.
