Reirradiation With Pembrolizumab in Locoregional Inoperable Recurrence or Second Primary Squamous Cell CA of the Head and Neck

Carcinoma, Squamous Cell of Head and Neck Clinical Trial

Official title: A Phase II Trial of Reirradiation Combined With Open Label Pembrolizumab in Patients With Locoregional Inoperable Recurrence or Second Primary Squamous Cell Carcinoma of the Head and Neck (SCCHN)

Status Active, not recruiting

Clinical Trial Summary

Eligible participants with locoregional inoperable recurrence or second primary squamous cell carcinoma of the head and neck will be treated with reirradiation combined with anti-PD-1 mAb MK-3475 (generic name: pembrolizumab, trade name Keytruda®).

Clinical Trial Description

Each participant will undergo screening and then be treated with reirradiation with 1.2 Gy BID, 5 days a week (weeks 1-5). MK-3475 (generic name: pembrolizumab, trade name Keytruda®) will be given at 200mg intravenous every 3 weeks starting day one of reirradiation and will be continued in all participants until 3 months post completion of reirradiation, at which time a PET/CT will be done to evaluate response. Participants with progressive disease (PD) will be taken off MK-3475 and followed for survival. Participants that have a complete response (CR) will be followed clinically and radiographically, and if disease recurs may be eligible to be retreated with MK-3475 for up to one year. Participants with partial response (PR) or stable disease (SD) will continue treatment with MK-3475 for up to two years unless one of the following occurs: - documented disease progression - unacceptable adverse event(s) - intercurrent illness that prevents further administration of treatment - investigator decision to withdraw the subject - withdrawal of consent - pregnancy - noncompliance - administrative reasons (i.e. trial is closed prematurely). Participants who have not progressed at completion of 24 months of therapy will be observed, but may be eligible for 1 year of retreatment with MK-3475 if they develop recurrence/progression and qualify for retreatment as detailed in the protocol,and if the trial is still ongoing. ;
