APG-3288 in relapsed/refractory blood cancers

Official title: A Phase I Study to Evaluate the Safety, Pharmacokinetics, and Preliminary Efficacy of APG-3288 in Patients With Relapsed/Refractory Hematological Malignancies

Run by Ascentage Pharma Group Inc. · NCT07424833 · Data updated 2026-11-12

This study tests APG-3288 alone to see if it can be safely given and what dose works best in people whose blood cancers have returned or stopped responding to standard treatments.

Is this trial a fit for you?

Likely a good fit

Adults with relapsed/refractory CLL/SLL, DLBCL (including Richter Transformation), MCL, WM, MZL, or FL who have had at least two prior systemic therapies and measurable disease.

Probably not a fit

Patients whose disease does not respond to APG-3288 or who experience unacceptable toxicity are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1, multicenter, open-label study of APG-3288 given orally once daily in 28-day cycles. Part 1 aims to find the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) in patients who have failed standard therapy. Part 2 expands to further evaluate safety and pharmacokinetics, with up to 60 patients per indication randomized to 2 or 3 dose cohorts. Eligible cancers include several relapsed/refractory hematologic malignancies such as CLL/SLL, DLBCL (including Richter Transformation), MCL, WM, MZL, and FL. Participants must have had at least two prior therapies and adequate organ function; key exclusions include concurrent anti-cancer therapies other than hormone replacements.

Why it matters

Potential benefit: If successful, participants may receive a dose with acceptable safety and potential activity for their cancer type, and the information could guide future studies of APG-3288.

How similar studies have gone: Early-phase trials in targeted therapies for hematologic cancers often clarify safety and dosing, with potential signals guiding later studies.

Key Inclusion Criteria:

* Eastern Cooperative Oncology Group (ECOG) status ≤ 1 in Part 1 (dose escalation), and ≤ 2 in Part 2 (dose expansion).
* Part 1 (Dose Escalation): histologically or cytologically confirmed diagnosis of R/R CLL/SLL, DLBCL (including Richter Transformation), MCL, WM, MZL, or FL.
* Prior systemic therapy: at least 2 prior lines of systemic therapy (including BTK inhibitor for approved indications) and who have failed or are not eligible for available therapies with established clinical benefit.
* Measurable disease per response criteria specific to the malignant condition.
* Adequate organ and bone marrow function.

Key Exclusion Criteria:

* Concurrent anti-cancer therapy (chemotherapy, radiation therapy, surgery, immunotherapy, hormonal therapy, targeted therapy, biologic therapy, with the exception of hormones for hypothyroidism or estrogen replacement therapy, anti-estrogen analogs, agonists required to suppress serum testosterone levels).
* Any investigational therapy within 14 days prior to the first dose of study drug or within 5 half-lives of the respective investigational drug (whichever is shorter).
* Persistent toxicities from prior radiotherapy, targeted therapy, immunotherapy, or chemotherapy agents that have not recovered to Grade \<2 (except for alopecia or vitiligo).
* Symptomatic brain metastases due to tumor involvement of the central nervous system (CNS). Patients with CNS tumors who have been treated, are asymptomatic, and who have discontinued steroids (for the treatment of CNS tumors) for \> 28 days may be enrolled.
* Use of therapeutic-dose anticoagulants or antiplatelet agents. (Use of low-dose anticoagulants to maintain central venous catheter patency is permitted)
* Biological growth factors within 7 days prior to the first dose of study drug.
* Patients who, in the investigator's judgment, have not adequately recovered from prior surgery, or have undergone major surgery within 28 days prior to enrollment, or minor surgery within 14 days prior to enrollment.
* Significant cardiac disease defined as:

  1. New York Heart Association class III or IV cardiac disease, including pre-existing uncontrolled, clinically-significant arrhythmia, congestive heart failure, or cardiomyopathy.
  2. Unstable angina, myocardial infarction, or a coronary revascularization procedure within ≤ 3 months prior to initiation of study treatment.
  3. History of left ventricular ejection fraction \< 50%.
  4. Poorly controlled hypertension, or history of poor compliance with antihypertensive drug regimens.
* Clinically active and uncontrolled symptomatic infection; well-controlled human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) infection may be considered for enrollment.
* Autoimmune diseases, active inflammatory bowel disease, chronic infections, or any other disease or condition associated with chronic inflammation.
* Concurrent use of QT-prolonging medications or history of torsades de pointes.
* Concurrent malignancy other than the one being treated in this study with the exception of the following: cured malignancy without recurrence within 3 years prior to study entry; completely resected basal cell and squamous cell skin cancer; completely resected carcinoma in situ of any type.
* Any severe and/or uncontrolled medical condition that, in the investigator's opinion, may compromise the individual's safety or the evaluation of study results.
* Prior treatment with: BTK degrader treatment or allogeneic stem cell transplant
