About

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.

Full description

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.

14 participants in 1 patient group

Pemetrexed and Carboplatin plus L-DOS47
Experimental group
Description:
Patients will be recruited into cohorts of L-DOS47 escalating doses, with a minimum of 3 and a maximum of 6 patients per cohort for the first and last two dosing cohorts, and a minimum of 1 and a maximum of 2 patients for the middle three dosing cohorts. The starting dose of L-DOS47 will be 0.59 µg/kg; further planned dose levels to be assessed are 0.78, 1.5, 3.0, 6.0, 9.0 and 12.0 µg/kg. The standard of care doses of pemetrexed \[500 mg/m2\] and carboplatin \[AUC6\], respectively, to be administered in combination with L-DOS47, will remain constant across cohorts.
