Brief Summary:
A first-in-human study to evaluate the safety, tolerability and maximum tolerated dose (MTD) and establish the recommended phase 2 dose (RP2D) of BBP-398, a SHP2 inhibitor, in patients with advanced solid tumors.

Condition or disease Intervention/treatment Phase
Tumor, Solid Drug: BBP-398 (Formerly known as IACS-15509) Phase 1

Detailed Description:
The first-in-human (FIH) study of BBP-398 will be an open-label, sequential-cohort, non-randomized, Phase 1/1B study utilizing BOIN dose escalation followed by an expansion phase in patients with MAPK pathway- or RTK-driven advanced solid tumors. The primary objective is to determine safety and tolerability of BBP-398, the MTD and RP2D. The secondary objectives are to assess the pharmacokinetic (PK) and pharmacodynamic (PD) profile, preliminary anti-tumor activity, objective response rate (ORR, complete response + partial response rate) and the duration of response (DoR) of BBP-398. The exploratory objective is to assess predictive biomarkers of response.

 Drug: BBP-398 (Formerly known as IACS-15509)
oral capsules
Experimental: Dose Expansion

Oral capsules administered at MTD/RP2D defined dose. Each treatment cycle will be 28 days in duration with BBP-398 administered, once daily (QD)

  • Cohort A: Advanced or metastatic KRAS mutant solid tumor
  • Cohort B: Advanced solid tumor with NF1 loss-of-function (LOF) or metastatic BRAF class II/III mutant solid tumor
 Drug: BBP-398 (Formerly known as IACS-15509)

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Determination of Maximum Tolerated Dose (MTD) and establish the RP2D of BBP-398. [ Time Frame: Completion of 1 Cycle ( 28 days) ]
    The MTD will be based on DLT.


Secondary Outcome Measures :
  1. Determination of anti-tumor activity of BBP-398 [ Time Frame: After 1 dose of BBP-398 ]
    Anti-tumor activity will be defined by objective response rate (ORR2, complete response + partial response rate) and duration of response (DOR3)

  2. Maximum observed plasma concentration (Cmax) of BBP-398 [ Time Frame: Approximately 6 weeks ]
    Maximum plasma concentration of BBP-398 after single and multiple dose administration of BBP-398

  3. Time to reach Cmax (Tmax) of BBP-398 [ Time Frame: Approximately 6 weeks ]
    The amount of time to reach Cmax after single and multiple dose administration of BBP-398

  4. Terminal half-life (t1/2) of BBP-398 [ Time Frame: Approximately 6 weeks ]
    Terminal half-life (t1/2) after single and multiple dose administration of BBP-398

  5. Area under the plasma concentration-time curve (AUC) of BBP-398 [ Time Frame: Approximately 6 weeks ]
    Area under the plasma concentration versus time curve after single and multiple dose administration of BBP-398

  • Patients must be willing and able to comply with the scheduled visits, treatment plan, laboratory tests and other specified study procedures.

Key Exclusion Criteria

  • Patients with known active Hepatitis B, Hepatitis C infection, or HIV infection.
  • Patients with a history of CVA, myocardial infarction or unstable angina within the previous 6 months before starting therapy.
  • Patients with clinically significant cardiac disease.
  • Patients with tumors harboring known activating mutations.
  • Patients with a known additional malignancy that is progressing or requires active treatment.
  • Patients with known central nervous system (CNS) tumors.
  • Patients with known active CNS metastases and/or carcinomatous meningitis.
  • Patients who have previously received a SHP2 inhibitor.
