 (submitted: April 27, 2020)
Progression-free Survival (PFS) at 2 years [ Time Frame: Up to 2 years ]
The proportion of participants whose disease has to progressed per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 at 2 years. PFS will be calculated from treatment initiation to disease progression or death from any cause for 2 years. Per RECIST 1.1, Progressive Disease (PD): 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).

PFS will be calculated from treatment initiation to disease progression or death from any cause or last follow up. Per RECIST 1.1, Progressive Disease (PD): 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).

Brief Title  ICMJE HPV-16 Vaccination and Pembrolizumab Plus Cisplatin for "Intermediate Risk" HPV-16-associated Head and Neck Squamous Cell Carcinoma
Official Title  ICMJE Phase II Study Evaluating HPV-16 Vaccination (ISA101b) and Pembrolizumab Plus Cisplatin Chemoradiotherapy for "Intermediate Risk" HPV-16 Associated Head and Neck Squamous Cell Carcinoma (HNSCC)
Brief Summary This clinical trial will evaluate a new combination of pembrolizumab, HPV-16 E6/E7 specific therapeutic vaccination (ISA101b) and cisplatin-based chemoradiotherapy for patients with newly diagnosed, local-regionally advanced, intermediate risk HPV-associated head and neck squamous cell carcinoma.
Detailed Description

This study aims to enroll 50 patients (male and female, age 18+) who have intermediate risk disease with histologically-confirmed head and neck squamous cell carcinoma with no evidence of distant metastasis. All patients will receive the same treatment and there is no active control group.

In this trial, patients will undergo biopsy followed by treatment with ISA101b vaccine which will be initiated 2 weeks prior to cisplatin-IMRT, and one week prior to the first dose of pembrolizumab. Vaccines will continue for 2 additional administrations at weeks 2 and 5, on the same day as successive pembrolizumab infusions. Pembrolizumab will be initiated 1 week prior to cisplatin-IMRT at the dose of 200 mg IV q3 weeks (+/- 3 days). Pembrolizumab will be continued concurrently through cisplatin-IMRT (weeks 3, 6 ), and continued for a 15 week maintenance period after completion of cisplatin-IMRT for a total pembrolizumab treatment period of 24 weeks (8 doses; 6 months).

Primary Purpose: Treatment
Condition  ICMJE

Intervention  ICMJE
  • Radiation: IMRT (Intensity Modulated Radiotherapy)
    Radiation therapy
  • Drug: Pembrolizumab
    A potent and highly selective humanized monoclonal antibody (mAb) of the IgG4/kappa isotype designed to directly block the interaction between programmed cell death protein 1 (PD-1) and its ligands, PD-L1 and PD-L2.
  • Drug: Cisplatin
    Chemotherapy
  • Biological: ISA101b
    ISA101b is a therapeutic cancer vaccine that induces specific immune responses to the oncogenic E6 and E7 antigens from HPV16.
    Other Name: HPV-16 Vaccine
Study Arms  ICMJE Experimental: IMRT + Pembrolizumab + Cisplatin + ISA101b

IMRT (Intensity Modulated Radiotherapy) of 70 Gy in 35 fractions over 7 weeks (5 fractions per week).

Pembrolizumab will be administered at 200 mg (fixed dose) IV every 3 weeks (+/- 3 days), beginning beginning one week (week -1) prior to concurrent cisplatin-IMRT.

Cisplatin will be administered at 100 mg/m2 IV on days 1(Week 0) and 22 (Week 3).

ISA101b will be administered as three rounds of vaccination 3-4 weeks apart via two SC injections per vaccination round at 100ug/peptide, before pembrolizumab treatment. Vaccination #1 will be administered 1 week before pembrolizumab.

Interventions:
  • Radiation: IMRT (Intensity Modulated Radiotherapy)
  • Drug: Pembrolizumab
  • Drug: Cisplatin
  • Biological: ISA101b

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Histologically-confirmed head and neck squamous cell carcinoma with no evidence of distant metastasis, with a primary site being the oropharynx. Squamous cell carcinoma of unknown primary, metastatic to cervical lymph nodes - patients can enroll provided all other eligibility criteria are met.
  • Patients must have intermediate risk disease.

    o Patients must meet one of the following criteria: Oropharynx: p16(+) PLUS HPV ISH(+) (DNA or RNA) AND one of the following; ≥ AND ≥ 10 pack-years tobacco exposure (see Tobacco Assessment Form, Appendix A)
