Phase I Study of the BBP-398 in Patients With Advance Solid Tumors
Study Details
Study Description
Brief Summary
This is an open label, dose escalation and expansion, two-part Phase I study for SHP-2 inhibitor BBP-398 to evaluate the safety, tolerability, pharmacokinetics, determine MTD and/or RP2D, and preliminary anti- cancer activity in Chinese subjects with advanced solid tumors and in Chinese subjects with advanced or metastatic EGFR-mutant NSCLC.

Detailed Description
The Part A of this phase I trial is an abbreviated dose escalation study of BBP-398 following the USA mono dose escalation study (Study NAV- 1001, clinicaltrials.gov ID NCT04528836). The purpose of this part is to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-cancer activity in Chinese subjects with advanced solid tumors. The Part B of this study is to explore the safety, tolerability and efficacy of BBP-398 in Chinese subjects with advanced or metastatic EGFR- mutant NSCLC at MTD and/or RP2D. This Phase I study will provide supportive data to enable Chinese patients to join the combo dose escalation and expansion studies and/or other clinical trials of BBP-398.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Part A Dose Escalation and Part B Dose Expansion Part A: Oral capsules taken in escalating levels to determine MTD/RP2D. Each treatment cycle will be 28 days in duration with BBP-398 administered, once daily (QD). Part B: Oral capsules administered at MTD/RP2D defined dose. Each treatment cycle will be 28 days in duration with BBP-398 administered, once daily (QD) |
Drug: BBP-398
BBP-398 (formerly known as IACS-15509) is a potent, selective, orally active allosteric inhibitor of SHP2, a tyrosine phosphatase that plays a key role in the RTK -MAPK signal transduction pathway. Key components of the MAPK pathway include the small GTPase RAS, the serine/threonine-protein kinase RAF, mitogen-activated protein kinase (MEK) and ERK. In cells, SHP2 binds to phosphorylated tyrosine residues in the intracellular domain of RTKs such as the EGFR, leading to activation of the downstream MAPK signaling pathway.

Outcome Measures
Primary Outcome Measures
- Determination of Maximum Tolerated Dose (MTD) of BBP-398 [Completion of 1 Cycle (28 days)]
The MTD will be based on DLT
- Determination of anti-tumor activity of BBP-398 [Completion of 1 Cycle (28 days)]
Anti-tumor activity will be defined by objective response rate (ORR, complete response + partial response rate) and duration of response (DOR) according to RECIST v1.1
Secondary Outcome Measures
- Part A:Maximum plasma concentration (Cmax) of BBP-398 [Approximately 6 months]
Maximum plasma concentration of BBP-398 after single and multiple dose administration of BBP-398
- Part A:Time to reach Cmax (Tmax) of BBP-398 [Approximately 6 months]
The amount of time to reach Cmax after single and multiple dose administration of BBP-398
- Part A: Terminal half-life (t1/2) of BBP-398 [Approximately 6months]
Terminal half-life (t1/2) after single and multiple dose administration of BBP-398
- Part A: Area under the plasma concentration-time curve (AUC) of BBP-398 [Approximately 6 months]
Area under the plasma concentration versus time curve after single and multiple dose administration of BBP-398
- Part A: Concentration of BBP-398 in urine [Approximately 6 months]
To evaluate BBP-398 excretion via urine after single and multiple dose administration of BBP-398.
- Part B: Concentration of BBP-398 in plasma [Approximately 6 months]
To evaluate BBP-398 plasma concentration after multiple dose administration of BBP-398.
