Official title
A Phase 1 First-in-Human Study of PTK7-Directed Antibody Drug Conjugate HWK-007 in Participants With Advanced Solid Tumors
Overview
HWK-007-101 is a multicenter, open-label, first-in-human (FIH) Phase 1 study evaluating HWK-007, a protein tyrosine kinase 7 (PTK7)-targeted antibody drug conjugate (ADC), in adult participants with advanced or metastatic solid tumors known to be expressing PTK7. The study employs a sequential dose escalation and dose expansion design without a control group.
Detailed description
The study consists of 2 phases, Phase 1a (dose escalation) and Phase 1b (dose expansion). In Phase 1a, participants with non-squamous Endothelial Growth Factor Receptor Wild type (EGFR Wt) NSCLC, platinum resistant ovarian cancer (PROC), and endometrial cancer will be enrolled. In Phase 1b, non-squamous EGFR Wt NSCLC expansion cohort(s) will be opened, based on the safety, tolerability, PK, and preliminary antitumor data in Phase 1a.
In Phase 1a of the study, HWK-007 will initially be administered as an intravenous (IV) infusion every 3 weeks (Q3W).
Interventions
- Drug HWK-007
HWK-007 is a PTK7- targeted ADC being developed for the treatment of solid tumors.
Primary outcome measures
- Determine Maximum Tolerated Dose (MTD) [Time frame: From Cycle 1, Day 1 until Cycle 1, Day 21 (21-day cycles)]
- Determine Maximum Administered Dose (MAD) [Time frame: From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycles) until the MTD is reached.]
- Determine the Recommended Dose for Expansion (RDE) [Time frame: From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycles) until MTD is identified.]
Secondary outcome measures (12)
- Characterize the Volume of Distribution (Vd) of HWK-007 (ADC, total antibody, CPT116, and CPT119) [Time frame: Cycle 1 and Cycle 4 (21-day cycles)]
- Assess ADA (Anti drug antibody) against HWK-007 [Time frame: Every cycle from Cycle 1, Day 1 (21-day cycles) until 30 days past the last dose of study drug for up to 24 months.]
- Evaluate the Overall Response Rate (ORR) [Time frame: From Cycle 1, Day 1 (21-day cycles), every 6-weeks for the first 4 assessments and then every 6 weeks for up to 24 months until disease progression or 24 months, whichever comes first.]
- Evaluate Overall Survival (OS). [Time frame: From Cycle 1, Day 1 (21-day cycles) until death or 24 months, whichever comes first.]
- Maximum Concentration - Cmax of HWK-007 (ADC, total antibody, CPT116, and CPT119) [Time frame: At Cycle 1 and Cycle 4 - (21-day cycles)]
- Time to Maximum Concentration (Tmax) of HWK-007 (ADC, total antibody, CPT116, and CPT119) [Time frame: At Cycle 1 and Cycle 4 (21-day cycles).]
- Area Under the Concentration Time Curve (AUC) for HWK-007 (ADC, total antibody, CPT116, and CPT119) [Time frame: Cycle 1 and Cycle 4 - (21-day cycles)]
- T1/2 - Half-life of HWK-007 (ADC, total antibody, CPT116, and CPT119) [Time frame: Cycle 1 and Cycle 4 (21-day cycles)]
- Clearance (CL) [Time frame: Cycle 1 and Cycle 4 (21-day cycles)]
- Evaluate the Duration of Response (DoR) to HWK-007 [Time frame: From Cycle 1, Day 1 (21-day cycles) until disease progression or 24 months, whichever comes first.]
- Evaluate Progression-free Survival (PFS) [Time frame: From Cycle 1, Day 1 (21-day cycles) infusion to End of Study (up to 24 months)]
- Evaluate Disease control Rate (DCR) [Time frame: From Cycle 1, Day 1 (21-day cycles) until disease progression or 24 months, whichever comes first.]
