Induction and Maintenance Treatment With PARP Inhibitor and Immunotherapy in HPV-negative HNSCC (PRIME)

This is an interventional treatment trial for Head and Neck Squamous Cell Carcinoma Read More

Inclusion Criteria:

1. Patients of both genders, aged ≥18 years;
2. Signed written informed consent;
3. Primary histologically proven p16 negative squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx amenable to surgery with curative intent. p16 status will be assessed as surrogate marker for HPV infection only for oropharyngeal cancers. p16 status will be assessed using the CINtec p16 Histology assay (Ventana Medical Systems, Tucson, AZ, USA) with strong and diffuse nuclear and cytoplasmic staining in at least 70% of cells used as the cutpoint for positivity.
4. Clinical stage III-IV(M0) according to the VIII edition of AJCC staging system; recurrent/metastatic HNSCC, or previously treated HNSCC with local or systemic therapies, are not eligible for this study.
5. Performance status ECOG 0-1;
6. Availability of fresh tumor tissue via biopsy and provided for study purposes;
7. Willing to provide blood and saliva samples for study purposes;
8. Absence of a second malignancy (except non-melanoma skin cancers, and the following in situ cancers: bladder, gastric, oesophageal, colon, endometrial, cervical/dysplasia, melanoma, or breast) unless a complete remission was achieved at least 2 years prior to study entry AND no additional therapy is required during the study period;
9. Patient has adequate organ and marrow function (absolute neutrophil count ≥ 1500, hemoglobin ≥ 9.0 gram/deciliter (g/dL), platelet count ≥ 100,000, total bilirubin ≤1.5 times institution's upper limit of normal, AST/SGOT and ALT/SPGT ≤ 2.5 times institutional upper limit of normal, albumin ≥ 2.0 g/dL, serum creatinine ≤ 1.5 times institutional upper limit of normal or creatinine clearance ≥ 60 milliliters per minute (mL/min) according to Cockroft-Gault formula, or local institutional standard method);
10. Patient must be able to swallow study drug;
11. Participant must agree to not donate blood during the study or for 90 days after the last dose of study treatment;

12. Female participant has a negative serum pregnancy test within 72 hours prior to taking study treatment if of childbearing potential and agrees to use an adequate method of contraception from screening through 180 days after the last dose of study treatment, or is of nonchildbearing potential. Nonchildbearing potential is defined as follows (by other than medical reasons):

    • ≥45 years of age and has not had menses for >1 year
    • Patients who have been amenorrhoeic for <2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
    • Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use an adequate barrier method throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. See Section 3.3 for a list of acceptable birth control methods. Information must be captured appropriately within the site's source documents. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient.
13. Participant must agree to not breastfeed during the study or for 90 days after the last dose of study treatment;
14. Male participant agrees to use an adequate method of contraception (Section 3.3 for a list of acceptable birth control methods) starting with the first dose of study treatment through 180 days after the last dose of study treatment. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient;
15. Participant must be able to understand the study procedures and agree to participate in the study by providing written informed consent.
