Study Details

Study Description

Brief Summary

The purpose of this research study is to evaluate the effectiveness of using a combination of pembrolizumab and olaparib when given before and after standard chemoradiation therapy in treating locally advanced head and neck squamous cell carcinoma. Pembrolizumab and olaparib are drugs that are approved for head and neck cancer treatment. However, FDA has not approved the use of these two drugs together in treating head and neck cancer.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

Treatment outcomes are poor for patients with locally advance human papilloma virus (HPV) negative and high-risk HPV positive head and neck squamous cell carcinoma (HNSCC). One standard of care (SOC) for HNSCC is definitive chemoradiotherapy (CRT). This study will evaluate the safety and efficacy of the addition of pembrolizumab, an anti-programmed death-1 (PD1) inhibitor, and olaparib, a Polyadenosine 5'diphosphoribose polymerization (PARP) inhibitor, before and after SOC CRT, which will be delivered in 70 Gray in 35 fractions with concurrent weekly cisplatin 40 mg/m2 over 7 weeks.

Treatment will be offered in three sequential phases. In the induction phase, participants will receive one infusion of pembrolizumab and will take olaparib tablets for a total of 21 days. In the chemoradiation phase, radiation therapy will administered daily (excluding weekends) and cisplatin infusion will be given weekly. In the maintenance phase, pembrolizumab infusion will be done once every 6 weeks in additional to twice daily olaparib tablets for up to 8 treatment cycles that are 42-days per cycle.

    Outcome Measures

    Primary Outcome Measures

    1. One Year Progression Free Survival (PFS) [up to 1 year from start of treatment]

      One Year PFS will be defined as the period from the date of treatment start until disease progression or death (whichever occurs first) up to one year. Subjects who have not had an event will be censored at the date of last disease assessment documenting the subject was free of progression. Progression will be evaluated by RECIST v1.1 RECIST v.1.1: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), no response or less response than Partial or Progressive; or Progressive Disease (PD), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

    Secondary Outcome Measures

    1. Overall survival [up to 2 years from start of treatment]

      Overall survival will be defined as the period from the date of treatment start until death of any cause. Subjects who have not had an event will be censored at the date of last assessment documenting the subject was alive.

    2. Two Year Progression Free Survival (PFS) [Up to 2 years from start of treatment]

      Two Year PFS will be defined as the period from the date of treatment start until disease progression or death (whichever occurs first) up to two year. Subjects who have not had an event will be censored at the date of last disease assessment documenting the subject was free of progression. Progression will be evaluated by RECIST v1.1 RECIST v.1.1: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), no response or less response than Partial or Progressive; or Progressive Disease (PD), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

    3. Induction therapy related delays in chemoradiation therapy [Up to 14 weeks from start of treatment]

      Induction therapy related delays in chemoradiation therapy (CRT) will be defined type and associated grade of toxicity according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0. criteria and days of delay to start CRT due to induction one cycle of induction pembrolizumab and olaparib.

    4. Toxicities related to maintenance therapy [Up to 2 years from start of treatment]

      Toxicities related to maintenance therapy associated with pembrolizumab and olaparib will be classified and graded according to NCI-CTCAE v5.0. The NCI Common Terminology Criteria for Adverse Events is a descriptive terminology which can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.

    5. Induction related toxicity using patient-reported outcomes [Up to 2 years from start of treatment]

      Induction pembrolizumab and olaparib related toxicity will be defined using Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) in subjects receiving one cycle of pembrolizumab and olaparib.

    6. Patient reported maintenance therapy-related toxicities [Up to 2 years from start of treatment]

      Maintenance therapy-related toxicities using patient-reported outcomes (PRO-CTCAE) in subjects who received induction pembrolizumab with olaparib, followed by definitive treatment with concurrent cisplatin-radiotherapy and maintenance pembrolizumab and olaparib.

    7. One-year locoregional control [Up to 1 year from start of treatment]

      One-year locoregional control will be defined as the period from the start of treatment until recurrence at primary site or nodal site (whichever occurs first) as defined by RECIST 1.1

    8. Distant Metastasis-Free Survival (DMFS) [Up to 1 year from start of treatment]

      DMFS will be defined as the period from the date of treatment start until distant metastasis or death (whichever occurs first) as defined by RECIST 1.1. Subjects who have not had an event will be censored at the date of last disease assessment documenting the subject was free of distant metastasis.

    9. Correlate Combined Positive Score (CPS) and one-year progression free survival (PFS) [Up to 1 year]

      To correlate combined positive score (CPS) with one-year PFS, quality of life scores will be summarized using descriptive statistics like mean, sd, median, range, in participants who received induction pembrolizumab with olaparib, followed by definitive treatment with concurrent cisplatin-radiotherapy and maintenance pembrolizumab and olaparib.

    10. Head and Neck Cancer Associated Patient Reported Outcomes (PRO) [Baseline, 4week, 7 week, 12 weeks, 6months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months]

      Head and Neck Cancer Associated PRO will be evaluated using European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Head and Neck Module (QLQ-H&N35). EORTC QLQ-H&N35 has 35 questions assessing symptoms and side effects of treatment, social function and body image/sexuality. Most questions used 4 point scale (1 'Not at all' to 4 'Very much'); several single item questions were just coded as no=1, yes=2. The scores transformed and analyzed on a 0 - 100 scale. High scores indicate more problems.

    11. General Cancer Associated Patient Reported Outcomes (PRO) [Baseline, 4week, 7week, 12 weeks, 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, 60 months]

      General Cancer Associated PRO will be evaluated using European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). The EORTC QLQ-C30 has 30 questions, 9 multi-items: 5 functional, 9 symptoms and a global health and quality-of-life. Most questions used 4-point scale (1 'Not at all' to 4 'Very much'); 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). The scores transformed and analyzed on a 0 - 100 scale. A higher score=better.
