Duvelisib Plus Docetaxel In Recurrent/Metastatic HNSCC

Inclusion Criteria

• •Participants must meet the following criteria on screening examination to be eligible to participate in the study:
• •Participants must have histologically confirmed squamous cell carcinoma of the head and neck (SCCHN) with evidence of recurrent, metastatic (R/M) or advanced, incurable disease from any mucosal subsite including oral cavity, oropharynx, larynx, hypopharynx, nasal cavity, and the paranasal sinuses.
• •Participants must have at least one RECIST v1.1 measurable lesion, as defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) ≥1 cm with CT scans or MR imaging.
• •Must have had at least 1, but no more than 2, prior lines of prior systemic therapy for R/M SCCHN; one of these lines should have included PD-1/L1 blockade
• •* Platinum-based therapy as part of definitive/adjuvant or curative-intent treatment can count as 1 prior line of therapy if the subject progressed within 6 months of receiving therapy.
• •* At least 2 weeks must have elapsed since the end of prior chemotherapy, biological agents (3 weeks for anti-cancer monoclonal antibody containing regimens) or any investigational drug product, with adequate recovery of treatment-related toxicity to NCI CTCAE Version 5.0 grade ≤1 (or tolerable grade 2) or back to baseline (except for alopecia or peripheral neuropathy).
• •Be ≥18 years of age on the day of signing informed consent.
• •Must provide prior data on tumor PD-L1 expression status and HPV status, if available
• •Have a performance status of 0 or 1 on the ECOG Performance Scale
• •Participants must have adequate organ and marrow function as defined below (within 14 days prior to study registration):
• •* absolute neutrophil count ≥ 1,000/mcL
• •* hemoglobin ≥ 9 g/dL
• •* platelets ≥ 100,000/mcL
• •* total bilirubin ≤ upper limit of normal (ULN)
• •* AST(SGOT)/ALT(SGPT) ≤ 2.5x institutional ULN (or ≤ 1.5x institutional ULN if concomitant with alkaline phosphatase \>2.5x institutional ULN) or ≤ 5x ULN for those with liver metastases
• •* serum creatinine ≤ 1.5x ULN OR creatinine clearance ≥ 60 mL/min/1.73 m2 for participants with creatinine levels above 1.5x ULN
• •* coagulation profile INR ≤ 1.5x ULN unless the participant is receiving an anticoagulant
• •Baseline tumor measurements must be documented from imaging within 28 days prior to study registration.
• •Female subjects of childbearing potential should have a negative urine or serum pregnancy test within 7 days of study registration. Female subjects of childbearing potential should have a negative urine or serum pregnancy test repeated within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• •Female and male subjects of childbearing potential must agree to use an adequate method of contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and 4 months after completion of stud drug administration. Contraception is required before starting the first dose of study medication through 120 days after the last dose of study medication. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
• •Be willing and able to provide written informed consent for the trial.
