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®).


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.

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. 7. Performance status of 0 or 1 on the ECOG Performance Scale. 8. Life expectancy greater than 12 weeks 9. Adequate organ function as defined by the protocol Exclusion Criteria: 1. Presence of distant metastatic disease. 2. Is currently participating in or has participated in a study of an investigational agent or used an investigational device within 4 weeks of the first dose of treatment. 3. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. 4. Has had a prior monoclonal antibody, chemotherapy, or targeted small molecule therapy within 4 weeks prior to study Day 1 or who has not recovered from adverse events due to agents administered more than 4 weeks earlier. 5. History of other malignancy within 5 years with the exception of prior Squamous cell carcinoma of the head and neck, adequately treated basal cell or squamous cell skin cancer, or carcinoma of the cervix. 6. Has an active autoimmune disease 7. Has evidence of interstitial lung disease or active, non-infectious pneumonitis. 8. Has an active infection requiring systemic therapy 9. Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways). 10. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies). 11. Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected). 12. Has received a live vaccine within 30 days prior to the first dose of trial treatment 13. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial.

Intervention

Radiation:
Reirradiation
Reirradiation 1.2 GY BID 5 days a week for 5 weeks.
Drug:
MK-3475
MK-3475 will be given at 200mg intravenous every 3 weeks starting day one of reirradiation and will be continued once every 3 weeks until 3 months post completion of reirradiation. Further continuation of MK-3475 will be determined by response evaluation at 3 months post completion of reirradiation

Outcome

Type Measure Description Time frame Safety issue
Primary 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). Up to 36 months (after starting reirradiation and MK-3475)
Secondary 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. Up to 36 months (after initiation of treatment with reirradiation and MK-3475)
Secondary 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). Up to 36 months (after initiation of treatment with reirradiation and MK-3475)
Secondary 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. Up to 36 months (after initiation of treatment with reirradiation and MK-3475)
Secondary 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. Up to 36 months (after initiation of treatment with reirradiation and MK-3475)
Secondary 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. Up to 36 months (after initiation of treatment with reirradiation and MK-3475)
