Study Details

Study Description

Brief Summary

The purpose of this study is to test the safety and tolerability of HFB301001 in patients with advanced cancers. There are two parts in this study. During the escalation part, groups of participants will receive increasing doses until a safe and tolerable doses of HFB301001 is determined. During the expansion part, participants will take the dose of study drug that was determined from the escalation part of the study and will be assigned to a group based on the type of cancer they have.

Detailed Description

This is a Phase I, first-in-human, open-label, dose escalation and expansion study in adult patients with advanced cancers. The study will comprise of:

  1. A Screening Period of up to 28 days

  2. A Treatment Period during which participants will receive the study drug on the first day of each cycle where each cycle is 28 days. Number of cycles depends on how the disease responds to the study drug

  3. A Follow-Up Period which involves 1 visit

Arms and Interventions

Arm Intervention/Treatment
Experimental: HFB301001

Participants will receive HFB301001 via intravenous infusions

Drug: HFB301001
Dose Escalation: Participants will be administered dose level 1 in Cohort 1. Participants in Cohorts 2-4 will receive dose levels 2-4, respectively. Dose Expansion: Participants with certain cancer types will be administered the dose determined at dose escalation.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with adverse events (AEs), serious AEs (SAEs), dose-limiting toxicities (DLTs), changes in laboratory values, vital signs and ECG parameters [Cycle 1 Day 1 to 30 days after the last dose of HFB301001 (each cycle is 28 days)]

  2. To determine a Recommended Phase 2 Dose (RP2D) during Dose Expansion [Cycle 1 Day 1 to 30 days after the last dose of HFB301001 (each cycle is 28 days)]

Secondary Outcome Measures

  1. Objective Response Rate (ORR) as determined by Response Evaluation Criteria in Solid Tumors (RECIST)1.1 and immune-RECIST (iRECIST) [Baseline to 30 days after the last dose of HFB301001 (each cycle is 28 days), assessed up to 3 years]

  2. Disease Control Rate (DCR) as determined by RECIST1.1 and iRECIST [Baseline to 30 days after the last dose of HFB301001 (each cycle is 28 days), assessed up to 3 years]

  3. Duration of Response (DOR) as determined by RECIST1.1 and iRECIST [Start of first response to first date of disease progression, clinical progression or death, whichever occurs first, assessed up to 3 years]

  4. Progression Free Survival (PFS) as determined by RECIST1.1 and iRECIST [Baseline to disease progression or death, whichever occurs first, assessed up to 3 years]

  5. Minimum serum concentration (Cmin) [Cycle 1 Day 1 to day of the last dose of HFB301001 (each cycle is 28 days)]

  6. Maximum serum concentration (Cmax) [Cycle 1 Day 1 to day of the last dose of HFB301001 (each cycle is 28 days)]

  7. Area under the concentration versus time curve (AUC) [Cycle 1 Day 1 to day of the last dose of HFB301001 (each cycle is 28 days)]

  8. Terminal half-life (T1/2) [Cycle 1 Day 1 to day of the last dose of HFB301001 (each cycle is 28 days)]

  9. Serum concentration for measurement of anti-HFB301001 antibodies [Cycle 1 Day 1 to day of the last dose of HFB301001 (each cycle is 28 days)]

  10. To assess the pharmacodynamic (PD) effects of HFB301001 in the blood and in the tumor [Cycle 1 Day 1 to Cycle 3 Day 2 (each cycle is 28 days)]

    Percent change in immunologic changes to immune cells in the blood and tumor
