Study Details

Study Description

Brief Summary

This is a Phase 1/2, open-label, multi-center, non-randomized, dose-escalation study of PT-112 in combination with the anti-PD-L1 antibody, avelumab, in selected advanced solid tumors.

The study is to be conducted in two parts: the Dose Escalation Phase of PT-112 within the combination and the Dose Confirmation Phase in patients with non-small cell lung cancer who will be treated at the RP2D.

Arms and Interventions

Arm Intervention/Treatment
Experimental: PT-112 in combination with avelumab

PT-112, administered by intravenous infusion avelumab, administered by intravenous infusion Patients with all listed conditions are eligible for treatment during the dose escalation phase of the study. Patients with NSCLC are eligible for the dose confirmation phase of the study.

Drug: PT-112
The RP2D of PT-112 when used in combination with avelumab has been determined during dose escalation and is being confirmed in the NSCLC dose confirmation cohort. For the NSCLC confirmation cohort, PT-112 will be administered at a dose of 360 mg/m2 on Days 1, 8 and 15.

Biological: avelumab
Avelumab will be administered at a fixed dose of 800 mg on Days 1 and 15.

Outcome Measures

Primary Outcome Measures

  1. NSCLC Cohort: Evaluate best overall response rate (ORR) by tumor type according to Immune-Response Criteria (iRECIST) in metastatic or locally advanced, squamous or non-squamous NSCLC. [24 months]

Secondary Outcome Measures

  1. NSCLC Cohort: Confirm the RP2D patients with metastatic or locally advanced, squamous or non-squamous NSCLC [24 months]

  2. NSCLC Cohort: Assess the safety profile of PT-112 in combination with avelumab [24 months]

  3. NSCLC Cohort: Evaluate disease control rate (CR, PR and SD lasting ≥6 months) overall and by tumor type based on iRECIST [24 months]

  4. NSCLC Cohort: Evaluate disease control rate (CR, PR and SD lasting ≥3 months) overall and by tumor type based on iRECIST [24 months]

  5. NSCLC Cohort: Evaluate median duration of response among responding patients [24 months]

  6. NSCLC Cohort: Evaluate median PFS [24 months]

  7. NSCLC Cohort: Evaluate PFS rate at 6 months from start of study drug, based on tumor assessments every 8 weeks based on iRECIST [24 months]
