Study summary
The purpose of this study is to test the safety and tolerability of HFB200603 as a single agent and in combination with tislelizumab in patients with advanced cancers. There are two parts in this study. During the escalation part, groups of participants will receive increasing doses of HFB200603 as a monotherapy or in combination with tislelizumab until a safe and tolerable dose of HFB200603 as a single agent or combination therapy is determined. During the expansion part, participants will take the doses of HFB200603 as a monotherapy (optional arm) or in combination with tislelizumab that were determined from the escalation part of the study and will be assigned to a group based on the type of cancer the participants have.
Eligibility
Inclusion Criteria:
* Patient must have one of the following cancers and previously received the following lines of systemic therapy for the advanced/metastatic disease:
* Renal cell carcinoma: at least 2 lines of therapy
* Non-small cell lung cancer: at least 2 lines of therapy
* Melanoma:
* BRAF V600E positive: must have received at least 2 lines of therapy
* BRAF V600E negative: must have received at least 1 line of therapy
* Gastric cancer: at least 1 line of therapy
* Colorectal cancer: at least 3 lines of therapy
* Suitable site to biopsy at pre-treatment and on-treatment
* Measurable disease as determined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
* Eastern Cooperative Oncology Group performance status of 0 or 1
Exclusion Criteria:
* Systemic anti-cancer therapy within 2 weeks prior to start of study drug or within 4 weeks for immune-oncologic therapy. For cytotoxic agents with major delayed toxicity (e.g., mitomycin C), 6 weeks of washout are mandated.
* Therapeutic radiation therapy within the past 2 weeks
* Active autoimmune diseases or history of autoimmune disease that may relapse
* Any malignancy ≤ 5 years before first dose of study drug except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated curatively
* Systemic steroid therapy (\>10 mg/day of prednisone or equivalent) or any immune suppressive medication ≤ 14 days before first dose
* Patients with toxicities (as a result of prior anticancer therapy) which have not recovered to baseline or stabilized, except for adverse events not considered a likely safety risk (e.g., alopecia, neuropathy, and specific laboratory abnormalities)
* Severe or unstable medical condition, including uncontrolled diabetes, coagulopathy, or unstable psychiatric condition
* Major surgery within 28 days of the first dose of study drug
* History of interstitial lung disease, non-infectious pneumonitis, or uncontrolled lung diseases including pulmonary fibrosis or acute lung diseases. For combination only: non-small cell lung cancer patients, or patients with significantly impaired pulmonary function or who require supplemental oxygen at baseline must undergo an assessment of pulmonary function at screening
* History of allergic reactions, immune related reactions, or cytokine release syndrome (CRS) attributed to compounds of similar chemical or biologic composition to monoclonal antibodies or any excipient of HFB200603 or tislelizumab
* For combination only: Prior randomization in a tislelizumab study regardless of the treatment arm, until the primary and key secondary endpoints of the study have read out
Primary outcome measure(s)
- Number of participants with adverse events (AEs) meeting protocol-defined Dose-Limiting Toxicity (DLT) criteria during Dose Escalation — The first cycle of treatment (Day 1 up to Day 21)
Severity of adverse events will be based on common terminology criteria for adverse events (CTCAE) version 5.0 - Number of participants with AEs — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
Severity of AEs will be assessed based on CTCAE version 5.0 (except for cytokine release syndrome which will be assessed by American Society for Transplantation and Cellular Therapy grading) - Number of participants with changes in laboratory values — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
- Number of participants with changes in vital signs — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
- Number of participants with changes in electrocardiogram (ECG) — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
- Number of participants with changes in tolerability (dose interruptions and dose intensity) — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
- To determine a Recommended Phase 2 Dose (RP2D) during Dose Expansion — Cycle 1 Day 1 to 90 days after the last dose of study drug(s) (each cycle is 21 days), assessed up to 3 years
