A Dose Escalation Study of L-DOS47 in Recurrent or Metastatic Non-Squamous NSCLC
Study Details
Study Description
Brief Summary
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.

Phase 1 |
Detailed 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.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Pemetrexed and Carboplatin plus L-DOS47 Patients will be recruited into cohorts of L DOS47 escalating doses, with a minimum of 3 and a maximum of 6 patients per cohort. The starting dose of L DOS47 will be 0.59 µg/kg; further possible dose levels that may be assessed are 0.78, 1.04, 1.38 and 1.84 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. |
Drug: L-DOS47
A treatment cycle will be 21 days, with patients receiving L DOS47 on cycle Days 1, 8, and 15 and pemetrexed/carboplatin on Day 1 of each treatment cycle.

Outcome Measures
Primary Outcome Measures
- Number of patients with adverse events as a measure safety and tolerability of L-DOS47 in combination treatment with pemetrexed/carboplatin [Participants will be followed for 12 weeks]
The AE reporting period starts on Cycle 1 Day 1 up to the last study visit.
Secondary Outcome Measures
- Objective response rate of patients receiving the combination treatment according to RECIST 1.1 [Up to 12 weeks]
Objective tumor response will be assessed according to RECIST version 1.1 in patients who have completed at least 2 cycles of study treatment and who have at least 1 post-treatment disease assessment.
- Number of patient receiving a sustained clinical benefit [Up to 12 weeks]
Defined as the percentage of patients who have achieved complete response, partial response, and stable disease following combination treatment with L-DOS47 + pemetrexed/carboplatin.
- Maximum observed plasma concentration (Cmax) of L-DOS47 after dosing in combination treatment with pemetrexed/carboplatin [Up to 12 weeks]
Pharmacokinetic parameters for L-DOS47 will be determined from plasma samples collected from all patients dosed with L-DOS47
- Time to maximum observed plasma concentration (Tmax) of L-DOS47 after dosing in combination treatment with pemetrexed/carboplatin [Up to 12 weeks]
Pharmacokinetic parameters for L-DOS47 will be determined from plasma samples collected from all patients dosed with L-DOS47
- Area under the concentration (AUC) vs time curve of L-DOS47 after dosing in combination treatment with pemetrexed/carboplatin [Up to 12 weeks]
Pharmacokinetic parameters for L-DOS47 will be determined from plasma samples collected from all patients dosed with L-DOS47
- Terminal elimination half-life of L-DOS47 after dosing in combination treatment with pemetrexed/carboplatin [Up to 12 weeks]
Pharmacokinetic parameters for L-DOS47 will be determined from plasma samples collected from all patients dosed with L-DOS47
- The presence of anti-L-DOS47 antibodies for patients dosed with L-DOS47 in combination treatment with pemetrexed/carboplatin [Up to 12 weeks]
Serum samples will be collected and analyzed from all patients dosed with L-DOS47
