Clinical summary

Summary

This study is testing a new drug called BG-75202 in people with myeloid blood cancers. Researchers want to find out:

  • how safe the drug is
  • what side effects it may cause
  • how the body processes the drug
  • how the drug affects cancer cells
  • whether the drug shows signs of helping to  treat myeloid cancers

BG-75202 may be given on its own or together with other anti-cancer treatments.

The study is an early-phase (Phase 1) trial, which means the main goal is to find a safe dose and learn more about how the treatment works. Researchers will also look for early signs that the treatment may help control the cancer.

Who can take part?
You may be eligible for this study if:

  • you are aged 18 years or older
  • you have been diagnosed with a myeloid blood cancer (myeloid malignancy)
  • your cancer has come back after treatment (relapsed) or has not responded to treatment (refractory)
  • you have received at least one previous treatment for your cancer
  • if your cancer has a genetic change that can be treated with a targeted therapy, you must have already received that treatment, unless it was not suitable, available, or you chose not to have it.

What treatment is being studied?
This study is testing a new investigational medicine called BG-75202, which is taken by mouth. The study is being conducted in stages to find a safe and suitable dose and to learn more about how the treatment works.

In the first part of the study (Phase 1a), different dose levels of BG-75202 will be tested to help identify a suitable dose. In the second part (Phase 1b), participants will receive BG-75202 at selected dose levels to further assess its safety and effects on the cancer.

Study treatment schedule

  • Phase 1a (Part A): BG-75202 taken by mouth on its own at increasing dose levels.
  • Phase 1a (Part B): BG-75202 taken by mouth together with a hypomethylating agent (HMA), while researchers test increasing dose levels of BG-75202.
  • Phase 1b: BG-75202 taken by mouth on its own at selected dose levels.

Conditions

This trial is treating people with relapsed or refractory myeloid malignancies

Eligibility

Inclusion

  • Patients must be ≥ 18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place), inclusive, at the time of signing the Informed consent form (ICF).
  • Patients must have a confirmed diagnosis of myeloid malignancies based on 2016 World Health Organization criteria, and meet the following categories:

    • Relapsed/refractory; myeloid malignancies after ≥1 prior systemic therapy, per ELN; 2022 criteria; patients with actionable genetic alteration must have previously received targeted therapies unless contraindicated, unavailable/inaccessible, or declined by patient.
  • Patients must have a stable Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2.

Exclusion

  • Prior exposure to KAT6A/B inhibitors/degraders.
  • A diagnosis of acute promyelocytic leukemia or BCR-ABL-positive leukemia.
  • Known central nervous system involvement by leukemia
  • Use of antileukemic therapies without sufficient washout period

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Inclusion

  • You have had treatment, but your cancer has come back (relapsed or recurrent).
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.

Exclusion

  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
