Study Endpoints

Primary Endpoints

Part 1: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
From the first dose of study drug(s) to 30 days after the last dose; approximately 6-12 months

Number of participants with treatment-emergent AEs and SAEs.

Part 1: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-68501
Up to approximately 24 months

MTD is defined as the highest dose evaluated for which estimated toxicity rate is the closest to the target toxicity rate. MAD is defined as the highest dose administered if MTD is not reached.

Part 1: Recommended dose(s) for Expansion (RDFE) of BG-68501 monotherapy in participants with solid tumors
Up to approximately 24 months

RDFE of BG-68501 alone will be determined based upon the MTD or MAD.

Part 1: RDFE of BG-68501 in combination with fulvestrant and BGB-43395 in participants with HR+/HER2- BC
Up to approximately 24 months

RDFE of BG-68501 in combination with fulvestrant and BGB-43395 will be determined based upon the MTD or MAD.

Part 2: Objective Response Rate (ORR)
Up to approximately 20 months

ORR is defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR). CR and PR that is confirmed by repeat assessments, as assessed by the investigator using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Secondary Endpoints

Part 1: ORR
Up to approximately 20 months
Part 2: Number of participants with AEs and SAEs
From the first dose of study drug(s) to 30 days after the last dose; approximately 6-12 months
Parts 1 and 2: Duration of Response (DOR)
Up to approximately 20 months

Part 1 Part A: Dose Escalation and Safety Expansion (BG-68501 Monotherapy)EXPERIMENTALSequential cohorts of increasing dose levels of BG-68501 will be evaluated as monotherapy.
Part 1 Part B: Dose Escalation (BG-68501 + Fulvestrant)EXPERIMENTALSequential cohorts of increasing dose levels of BG-68501 will be evaluated in combination with fulvestrant.
Part 1 Part C: Dose Escalation and Safety Expansion (BG-68501 + Fulvestrant + BGB-43395)EXPERIMENTALSequential cohorts of increasing dose levels of BG-68501 will be evaluated in combination with fulvestrant and BGB-43395.
Part 1: Food Effect EvaluationEXPERIMENTALParticipants will receive BG-68501 at a dose level that is determined safe and tolerable to evaluate food effect. Food effect may also be evaluated for BG-68501 in combination with fulvestrant.
Part 2: Dose ExpansionEXPERIMENTALThe RFDE for BG-68501 (as monotherapy and in combination with fulvestrant and BGB-43395) from Part 1 will be evaluated in selected tumor cohorts.

Frequently asked questions about BG-68501

What is BG-68501 used for?

BG-68501 is an investigational small molecule being studied for the treatment of breast cancer, including hormone-receptor-positive, HER-2 negative breast cancer and triple-negative breast cancer. It is also being evaluated in other advanced solid tumors such as small cell lung cancer, ovarian cancer, gastric cancer, endometrial cancer, prostate cancer, gastroesophageal cancer, and bladder cancer.

What does BG-68501 target?

BG-68501 targets CDK2, a protein involved in cell cycle regulation. By inhibiting CDK2, the drug is designed to interfere with cancer cell proliferation. It is being developed as a targeted therapy for biomarker-selected patients with advanced-stage tumors.

Who is developing BG-68501?

BG-68501 is being developed by BeOne Medicines Ltd., a biopharmaceutical company listed on the stock exchange under the ticker ONC. The company is conducting clinical research to evaluate the safety and efficacy of this investigational drug in patients with advanced cancers.

What phase is BG-68501 in?

BG-68501 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still being studied in clinical trials to assess its safety, tolerability, and potential effectiveness in treating advanced-stage tumors.

What clinical trials is BG-68501 in?

BG-68501 is being studied in a Phase 1 clinical trial registered as NCT06257264. This trial is examining the safety of different doses of BG-68501 in participants with advanced-stage tumors. The study is currently recruiting and aims to enroll approximately 258 participants across multiple countries, including the United States, Australia, China, Israel, Moldova, and New Zealand.

Is BG-68501 the same as other CDK2 inhibitors?

BG-68501 is a specific investigational small molecule that targets CDK2. While it belongs to the class of CDK2 inhibitors, it is a distinct drug candidate developed by BeOne Medicines Ltd. No alternative names for BG-68501 have been reported in the clinical trial information.
