E.3 | Principal inclusion criteria |
AIM-HN
1. At least 18 years of age.
2. Histologically confirmed head and neck cancer (oral cavity, pharynx, larynx, sinonasal, nasopharyngeal, or unknown primary) of squamous histology not amenable to local therapy with curative intent (surgery or radiation therapy with or without chemotherapy). Enrollment may proceed with local diagnosis but all subjects must consent to provide tumor tissue for a central pathology review.
3. Documented treatment failure from most recent prior therapy (e.g. tumor progression, clinical deterioration, or recurrence), and from at least one prior platinum-containing regimen, in any treatment setting. The most recent prior and platinum-based therapy may be the same regimen. Those subjects who, at the judgment of the investigator, are considered clinically unsuitable to receive standard platinum-containing regimen, may also be enrolled and the reason for clinical unsuitability recorded. There is no limit on the number of prior lines of therapy.
4. Known tumor missense HRAS mutation detected by Next Generation Sequencing (NGS) or any other methodology approved by the Sponsor. Variant allele frequency (VAF) needs to be determined and must be available. HRAS status should be assessed on tumor tissue obtained subsequent to the most recent prior therapy so that the most accurate tumor biology is evaluated. If tumor tissue that does not meet this criterion must be used (e.g. risk of new biopsy is too high, patient refuses new biopsy), the investigator should document the reason. Enrollment may proceed with the identification of a missense HRAS mutation using a test preferred by the investigator and approved by the Sponsor during pre-screening, but all subjects must consent to provide tumor tissue for central HRAS confirmation.
a) At least 59 per-protocol subjects must have a VAF ≥20%
b) No more than approximately 21 per-protocol subjects may have a VAF of <20%
5. Measurable disease by RECIST v1.1 (Appendix I) that meets the criteria for selection as a target lesion according to RECIST v1.1. The presence of at least one measurable target lesion per RECIST v1.1 must be confirmed by local radiology prior to subject entry.
6. At least 2 weeks or 5 half-lives, whichever is longer, since the last systemic therapy regimen prior to Cycle 1 Day 1. Last dose of any prior checkpoint inhibitor therapy must have been administered at least 2 weeks prior to C1D1. Subjects must have recovered to NCI CTCAE v5.0 < Grade 2 from all acute toxicities (excluding Grade 2 toxicities that are not considered a safety risk by the Sponsor and Investigator) or toxicity must be deemed irreversible by the Investigator.
7. At least 2 weeks since last radiotherapy. Subjects must have recovered from all acute toxicities from radiotherapy.
8. ECOG performance status of 0-1 (Appendix II).
9. Acceptable liver function:
a) Bilirubin ≤ 1.5 times upper limit of normal (x ULN).
b) AST (SGOT) and ALT (SGPT) ≤ 1.5 x ULN.
The subject must meet/continue to meet these criteria at the time of first dosing, as confirmed by analysis within 72 hours of C1D1.
10. Acceptable renal function with either serum creatinine ≤ 1.5 x ULN or a calculated creatinine clearance ≥ 60 mL/min using the Cockcroft-Gault or Modification of Diet in Renal Disease (MDRD) formulas.
The subject must meet/continue to meet these criteria at the time of first dosing, as confirmed by review of analysis performed within 72 hours of C1D1.
11. Acceptable hematologic status:
a) ANC ≥1000 cells/μL.
b) Platelet count ≥ 75,000/μL.
c) Hemoglobin ≥ 8.0 g/dL.
The subject must meet/continue to meet these criteria at the time of first dosing, as confirmed by review of analysis performed within 72 hours of C1D1.
12. Female subjects must be: see protocol
13. Written and voluntary informed consent understood, signed and dated.
SEQ-HN
1. At least 18 years of age.
2. Histologically confirmed head and neck cancer (oral cavity, pharynx, larynx, sinonasal, nasopharyngeal, or unknown primary) of squamous histology.
3. HRAS wildtype (i.e. have no identified tumor missense HRAS mutation) determined by a test preferred by the investigator and approved by the Sponsor or through central HRAS testing.
4. Will or has received at least one systemic anti-cancer therapy for recurrent or metastatic HNSCC for which there is available outcome information in terms of ORR, or can be determined based on the subject’s records. Subjects who have not yet received or completed at least one systemic anti-cancer therapy for recurrent or metastatic HNSCC must consent to the collection of treatment outcome information and additional follow up contact in order to participate in the SEQ-HN portion of the study.
5. Written and voluntary informed consent understood, signed and dated.
