New pill shows promise for tough blood cancers
NCT ID NCT05147467
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called APG-2575 in people whose chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) has come back or stopped responding to other treatments. About 75 adults will take the drug alone to see if it can shrink tumors and control the disease. The goal is to find a new option for patients who have run out of effective therapies.
Why investors are watching
Ascentage Pharma is running a phase II registration trial of APG-2575 as a single drug in patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. For a small company, this readout is a key test of whether the drug can work on its own and support a regulatory filing, which would be a major step for its pipeline.
If it works: A positive result could support a marketing application and give Ascentage a path to its first approved product in this indication. That would validate the drug's value and strengthen the company's position with regulators and partners.
If it fails: The trial could fail to show enough benefit or safety problems could emerge, which would delay or end the program. Trials in this setting often fail, and for a small company, a negative readout could hurt its prospects and financial position.

Inclusion Criteria: Subjects who meet each of the following inclusion criteria are eligible to participate in this study: 1. Age ≥18 years old. 2. Pathologically confirmed CLL/SLL according to the 2018 revised IWCLL NCI-WG guidelines, subject with measurable lesions or splenomegaly due to CLL. 3. Expected survival is at least 12 weeks. 4. Refractory, recurrent, or intolerant to BTK inhibitors and immunochemotherapy,or first-line treatment with BTK inhibitors fails and is not suitable for immunochemotherapy. 5. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS): 0 -2. 6.

Willingness and ability to comply with study procedures and follow-up examination. Exclusion Criteria: Subjects who meet any of the following exclusion criteria are not to be enrolled in this study: 1. Prior history of allogeneic hematopoietic stem cell transplantation, adoptive cell immunotherapy or autologous hematopoietic stem cell transplantation within 24 months. 2. Failure to recover adequately, at the discretion of the investigator, from prior surgical procedures. Patients who have had major surgery within 28 days from study entry, and patients who have had minor surgery within 14 days of study entry. 3. Received Bcl-2 inhibitor treatment. 4. Invasive NHL transformation or central nervous system (CNS) involvement has occurred. 5. Pregnancy or lactation, or pregnancy is expected during the study period or within 3 months after the last administration of treatment. 6. Within 2 years before entering the study, the subject had a history of active malignant tumors other than CLL / SLL, except that: * Fully treated cervical carcinoma in situ; * Completely resected basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin; * Confinement and resection of previously cured malignancies (or other treatment). 7. Any other condition or circumstance that would, at the discretion of the investigator, make the patient unsuitable for participation in the study.
