COPAN-ORL06: Copanlisib in Association With Cetuximab in Patients With Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinomas Harboring a PI3KCA Mutation/Amplification and/or a PTEN Loss
Study Details
Study Description
Brief Summary
The study consists of two distinct and sequential parts:
-
A Phase Ib aimed at determining the MTD (Maximum Tolerated Dose) of the combination (copanlisib/cetuximab) and the RP2D
-
A Phase II aimed at evaluating the efficacy of the combination at the RP2D (Recommended Phase 2 Dose)
All patients will be treated with the Copanlisib, a selective PI3KCA inhibitor, in association with Cetuximab.

Outcome Measures
Primary Outcome Measures
- Phase Ib (dose escalation phase): to determine the Maximal Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) of Copanlisib in association with Cetuximab [1 month]
Determination of the MTD will be based on the occurence of Dose Limiting Toxicities during Cycle 1.
- Phase II (expansion phase) : to assess the efficacy of the combination (Copanlisib + Cetuximab) at the RP2D. [16 weeks]
Efficacy of the combination will be assessed through Progression Free Survival at week 16.
Secondary Outcome Measures
- Efficacy of the combination [Through the study completion with an average of 10 months]
Objective Response Rate (ORR) using RECIST 1.1 criteria
- Efficacy of the combination [Through the study completion with an average of 10 months]
Overall Survival (OS)
- Adverse Events (NCI CTCAE v4.0) [Up to 15 cycles]
All Adverse Events (NCI CTCAE v4.0), related or not related to Copanlisib or Cetuximab, will be collected in the Case Report Form in order to picture the safety profile of the association.
- Copanlisib Maximum Plasma Concentration [Cmax] [First Month (at Day 1 and Day 15)]
For patients enrolled in the phase Ib (dose escalation phase) pharmacokinetic samples (blood) will be collected at Cycle 1 Day 1 and Cycle 1 Day 15. There will be 5 samples per day: pre-infusion, end of infusion, 2 hours, 8 hours and 24 hours after the start of Copanlisib infusion.
- Area Under the Curve [AUC] for Copanlisib pharmacokinetic [First Month (at Day 1 and Day 15)]
For patients enrolled in the phase Ib (dose escalation phase) pharmacokinetic samples (blood) will be collected at Cycle 1 Day 1 and Cycle 1 Day 15. There will be 5 samples per day: pre-infusion, end of infusion, 2 hours, 8 hours and 24 hours after the start of Copanlisib infusion.
- Mutational profile of circulating tumoral DNA (ctDNA) [through the study duration: baseline, C1D1, C1D15, 8 weeks, disease progression]
For patients enrolled in the phase II (dose escalation phase) blood samples will be collected at baseline, C1D1, C1D15, 8 weeks, Disease progression or end of treatment whichever comes first.
