A Phase 1/2 Open-Label, Multicenter, First-in-Human Study of the Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of BH-30643 in Adult Subjects With Locally Advanced or Metastatic NSCLC Harboring EGFR and/or HER2 Mutations (SOLARA)
Summary
This Phase1/2, open label, multicenter study will assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics and preliminary anti-tumor activity of BH-30643 in patients with NSCLC having EGFR and/or HER2 mutations. Phase 1 will determine the recommended Phase 2 dose (RP2D) and, if applicable, the maximum tolerated dose (MTD) of BH-30643. Phase 2 will further evaluate the antitumor efficacy and safety in specified cohorts determined by EGFR/HER2 mutation subtypes and/or treatment history at the RP2D, as well as the population PK.
Detailed description
BH-30643 is a novel, orally available, non-covalent, macrocyclic, mutant selective OMNI-EGFR inhibitor that targets a broad diversity of mutations in the EGFR kinase domain. These include EGFR classical mutations (e.g., ex19del and L858R) as well as less common (atypical) mutations (including G719X, S768I, L861Q, E709X, and beyond). BH-30643 also overcomes a variety of mutations which can cause resistance to previously approved EGFR TKIs (including both C797S and T790M). BH-30643 was designed to be selective over wildtype EGFR and HER2.

Outcome measures
Primary
Dose-limiting toxicities (DLTs) (Phase 1, Dose Escalation)
Assess dose-limiting toxicities (DLTs) as defined in the study protocol.
Time frame: Within the first 21 days of the first dose of BH-30643.
Recommended Phase 2 dose (RP2D) (Phase 1, Dose Expansion/Optimization)
Determine the RP2D for Phase 2.
Time frame: Within 21 days of last participant dosed during Dose Expansion/Optimization.
Objective Response Rate (ORR) (Phase 2)
Determine ORR as assessed by Blinded Independent Central Review (BICR).
Time frame: Approximately 3 years after the first participant dosed.
Secondary
Safety
Time frame: From enrollment through study completion, approximately 48 months.
Area under the plasma concentration-time curve from time zero to time of the last quantifiable concentration (AUClast) of BH-30643 for Single dose (Phase 1).
Time frame: Predose and up to 24 hours postdose.
Maximum observed plasma concentration (Cmax) of BH-30643 for Single dose (Phase 1).
Time frame: Predose and up to 24 hours postdose.
Time to reach Cmax (Tmax) of BH-30643 for Single dose (Phase 1).
Time frame: Predose and up to 24 hours postdose.
Area under the plasma concentration-time curve at steady state (AUCss) of BH-30643 for multiple doses (Phase 1) at steady state.
Time frame: Predose and up to 24 hours postdose.
Objective Response Rate (ORR)
Time frame: From enrollment until the date of the first documented progression or death from any cause, whichever occurs first, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
Disease Control Rate (DCR)
Time frame: From enrollment until the date of the first documented progression or death from any cause, whichever occurs first, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
Clinical benefit Rate (CBR)
Time frame: From enrollment until the date of the first documented progression or death from any cause, whichever occurs first, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
Time to Tumor Response (TTR)
Time frame: From first dose to the first occurrence of response, assessed up to the date of first documented progression or death from any cause, whichever occurs first (up to approximately 4 years).
Duration of Response (DOR)
Time frame: From first occurrence of response until the date of the first documented progression or death from any cause, whichever occurs first, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
Progression-free Survival (PFS)
Time frame: From enrollment until the date of the first documented progression or death from any cause, whichever occurs first, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
Overall Survival
Time frame: From enrollment until the date of death from any cause, assessed up to study ends or patient discontinue from the study, whichever occurs first (up to approximately 4 years).
ERTC-QLC-C30
Time frame: From enrollment until the end of treatment, up till patient discontinue from treatment due to any reason (up to approximately 4 years).
NSCLC-SAQ
Time frame: From enrollment until the end of treatment, up till patient discontinue from treatment due to any reason (up to approximately 4 years).
