About this trial

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, both as a monotherapy and in combination with chemotherapy.

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

≥ 18 years or legal adult.

Has at least 1 measurable target extracranial lesion according to RECIST v1.1.

Eastern Cooperative Oncology Group Performance Status ≤ 1.

Disqualifiers

History of any concurrent malignancy within the previous 2 years.

Known other oncogenic driver alterations (eg, moderate or high MET amplification) or histological transformation (eg, to small cell carcinoma, etc.).

Unresolved toxicities from prior therapies.

Any significant and uncontrolled medical condition, such as infection.

Trial outcomes

Primary outcomes

1

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.
2

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.
3

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 outcomes

1

Safety

Assess incidence and severity of treatment-emergent adverse events (TEAEs), as defined by CTCAE, V5.0 (Phase 1 and Phase 2).

Time frame
From enrollment through study completion, approximately 48 months.
2

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).

Determine area under the plasma concentration-time curve from time zero to time of the last quantifiable concentration (AUClast) of BH-30643.

Time frame
Predose and up to 24 hours postdose.
3

Maximum observed plasma concentration (Cmax) of BH-30643 for Single dose (Phase 1).

Determine maximum observed plasma concentration (Cmax) of BH-30643.

Time frame
Predose and up to 24 hours postdose.
4

Time to reach Cmax (Tmax) of BH-30643 for Single dose (Phase 1).

Determine time to reach Cmax (Tmax) of BH-30643.

Time frame
Predose and up to 24 hours postdose.
