Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Patients with biopsy proven locoregional recurrence or second primary SCCHN which is unresectable or the patient is unwilling to undergo resection. Determination of unresectability will be based on multidisciplinary review of each case.

Inclusion Criteria:

Be willing to undergo percutaneous endoscopic gastrostomy (PEG) placement, if necessary.
Have at least one measurable area of disease based on RECIST 1.1 within the previously radiated field.
Have provided adequate tissue for PD-L1 analysis either from an archival tissue sample or fresh biopsy done to confirm recurrence/second primary. Archival tissue sample can only be used if done within 3 months of enrollment on the clinical trial.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Reirradiation + MK-3475

Reirradiation 1.2 Gy BID for 5 days a week for 5 weeks with MK-3475 (Keytruda, pembrolizumab) 200mg intravenous every 3 weeks until 3 months post completion of reirradiation.

Outcomes

Primary Outcome Measures

Progression free survival

Number of months from the date of initiation of treatment to the date of progression of disease or death (whichever occurs first). Progressive disease, per RECIST 1.1, is defined as: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

Secondary Outcome Measures

Overall Response Rate (ORR)

Overall response rate, which will be determined per RECIST 1.1, is defined as the percentage of the patients who have a either Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm, or, Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The patient's best overall response rate defined as the best response recorded from the start of the treatment until disease progression will be recorded.

Time to in field disease progression

Number of months from initiation of treatment to progression of disease within the radiation field.Progressive disease, per RECIST 1.1, is defined as: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

Overall survival (OS)

Number of months from first treatment until death. Patients who are alive will be censored at the last date of patient contact.

Quality of life using EORTC QLQ-C30 and EORTC QLQ-H&N 35

Patient reported outcomes will be measured using EORTC QLQ-C30 and EORTC QLQ-H&N35 questionnaires. This tool contains 30 items. It measures 5 functional dimensions (physical, role, cognitive, social, emotional), 6 single items (appetite loss, constipation, dyspnea, financial impact, sleep disturbance, diarrhea), 3 symptom items (fatigue, pain, nausea/vomiting) and a global health and quality of life scale. Scales range in score from 0 to 100. A high score for a functional scale represents a high/healthy level of functioning whereas a high score for a symptom scale or item represents a high level of symptomatology or problems.

Clinical Benefit Rate (CBR)

The percentage of patients that have achieved a complete response, partial response, and stable disease as defined by RECIST 1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm, Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, or Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

5. Study Description

Brief 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®).

Detailed 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.
