A Study of HC-7366 to Establish the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D)

This is a first in human, multicenter, open label, Phase 1a/b dose escalation and dose
expansion study to establish the maximum tolerated dose (MTD), recommended Phase 2 dose
(RP2D), and evaluate the safety and tolerability of QD oral dosing of HC 7366 in a dose
escalating fashion in subjects with advanced solid tumors. Up to 36 subjects will be enrolled
into the Phase 1a dose escalation part of the study. Every effort will be made to ensure
approximately 50% of all subjects enrolled in this study will be subjects with the tumors of
special interest such as squamous cell carcinoma of the head and neck (SCCHN), colorectal
cancer (CRC), non-small cell lung cancer (NSCLC), and transitional cell carcinoma of the
bladder (TCC). Subjects with other solid tumor types are also eligible provided study
selection criteria are met and they do not exceed 50% of all enrolled subjects. The study
will be conducted in the United States at approximately 3 to 5 sites. This Phase 1a/b study
will follow a traditional 3+3 design. The starting dose level will be 10 mg QD, escalating to
20, 40, 75, 125, and 150 mg QD as safety allows. All doses are to be administered in the
fasting state with water at least 1 hour before food or at least 2 hours after food. The
Phase 1b dose expansion part will involve cohort expansion at up to 2 dose levels selected
from the dose escalation data by the safety monitoring committee (SMC), to obtain additional
safety and preliminary efficacy information. Each cohort in Phase 1b will enroll 15 subjects.
The study will be expanded into a Phase 2 study via protocol amendment which will then assess
the dose and tumor type(s) selected in Phase 1a/b as the most appropriate for further
clinical development. Subjects will be dosed until unacceptable toxicity, disease progression
per immune-related Response Evaluation Criteria in Solid Tumors (iRECIST), discontinuation of
treatment for other protocol allowed reason (eg, subject refusal), any other administrative
reasons, or after 2 years of treatment, whichever occurs first. For scheduling purposes,
dosing will occur in 3 week cycles and computed tomography (CT) scans will be conducted once
every 6 weeks with the first postbaseline scan after 6 weeks of dosing (precycle 3).

18 Years
Inclusion Criteria:

Have a signed an informed consent form prior to any study specific procedures or treatment

Be 18 years of age (male or female) at the time of consent

Have 1 of the following tumor types with qualifying characteristics, and have received at least 1 and no more than 5 prior lines of therapy:





Other solid tumors (eg, carcinoma of unknown primary) with the exception of rapidly progressing neoplasms (eg, pancreatic cancer, glioblastoma, hepatocellular carcinoma). Note: Subjects do not need to have progressed through all possible available therapies with known clinical benefit for their respective cancers to participate in this study. Note: Subjects with SCCHN, CRC, NSCLC, and TCC are a priority and should constitute as a whole, at least 50% of the enrolled population. Enrollment of all others will be capped when reaching a combined 50%, in order to maintain 18 slots for subjects with SCCHN, CRC, NSCLC, and TCC.

Have at least 1 radiologically measurable lesion as per Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 defined as a lesion that is at least 10 mm in longest diameter or lymph node that is at least 15 mm in short axis imaged by CT scan or magnetic resonance imaging and obtained by imaging within 28 days prior to study treatment. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions

Have resolution of all previous treatment related toxicities to Grade 1 severity or lower, except for stable sensory neuropathy (Grade 2) and alopecia. If the subject received major surgery or radiation therapy of >30 Gy, they must have recovered from the toxicity and/or complications from the intervention

If subjects were previously treated with immune checkpoint inhibitors, at least 4 weeks must have elapsed since the last dose, and toxicities resolved as above

Subjects must have at least one biopsiable lesion at baseline. Biopsies in this clinical study will conform to American Society of Clinical Oncology's Ethical Framework for Including Research Biopsies in Oncology Clinical Trials. Provided there are suitable and accessible lesions, no biopsy contraindications, minimal risk of complications and a positive informed decision, subjects are willing to provide fresh tissue for biomarker analysis, and, based on the adequacy of the tissue sample quality, for assessment of biomarker status. Two biopsies will be necessary: at baseline (within 15 days prior to study Day 1) and at the time of the first response assessment CT scan at Cycle 3/Day 1 (+7 days). Newly obtained biopsy specimens are preferred to archived samples and formalin fixed, paraffin embedded block specimens are preferred to slides

Have Eastern Cooperative Oncology Group performance status of 0 or 1 and sustained between screening and initiation of dosing on Day 1

Have no swallowing difficulties that would prevent compliance with oral dosing

Have not experienced >10% body weight loss in the previous 4 weeks

Have a serum albumin level >3 g/dL

Have life expectancy of 3 months or greater as determined by the treating physician

Have adequate organ function on Day 1, as defined by meeting all of the following criteria:

Total bilirubin 1.5 upper limit of normal (ULN) OR direct bilirubin ULN for subjects with total bilirubin levels >1.5 x ULN

Aspartate aminotransferase and alanine aminotransferase 2.5 ULN or 5 ULN for subjects with known hepatic metastases

Have adequate renal function on Day 1, as defined by creatinine 1.5 ULN and creatinine clearance 60 mL/min, as per the below Cockcroft Gault formula

Have adequate hematologic function on Day 1, as defined by meeting all of the following criteria:

Hemoglobin 9 g/dL (uncorrected by red blood cell transfusion or erythropoietin support)

Absolute neutrophil count 1.5 109/L

Platelet count 100 109/L
