About this trial

Evaluation of the safety, tolerability, pharmacokinetics, and preliminary efficacy of XS-04 in patients with relapsed or refractory hematologic malignancies

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Voluntarily participate in the clinical trial and sign the informed consent form (ICF).

Age ≥18 years, ≤75 years, regardless of gender.

Dose escalation phase: Patients with mature B-cell malignant tumors confirmed by histopathology according to the 2017 World Health Organization (WHO) classification, who have failed existing treatments and have no suitable treatment options and have treatment indications.

For indolent B-NHL (follicular lymphoma [FL], marginal zone lymphoma [MZL], and Waldenström macroglobulinemia [WM]), patients must have received at least two lines of systemic therapy, including at least one line of combination therapy containing anti-CD20 antibodies; for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), patients must have received at least two lines of systemic therapy, including BTK inhibitors or BCL-2 inhibitors; for MCL, patients must have received at least two lines of systemic therapy (including anti-CD20 antibodies, BTK inhibitors, etc.); for aggressive B-NHL (DLBCL), patients must have failed or relapsed after at least two lines of systemic therapy and are not suitable for hematopoietic stem cell transplantation.

Disqualifiers

Burkitt lymphoma/leukemia, plasma cell myeloma, plasmablastic lymphoma.

Acute promyelocytic leukemia (APL) or BCR-ABL positive AML patients or those with a history of myeloproliferative neoplasms (MPN).

Use of other cytotoxic drugs, investigational drugs, or other antitumor drugs within 14 days or 5 half-lives before the first dose of the study drug (whichever is shorter) (except hydroxycarbamide and leukapheresis). Patients who received tumor immunotherapy, antibody, or peptide antitumor drug treatment within 4 weeks before the first dose of the study drug.

Patients who underwent therapeutic surgery other than diagnostic, biopsy, or drainage procedures within 4 weeks before the first dose of the study drug, or who are expected to undergo major surgery during the study. For patients who underwent drainage procedures (e.g., thoracic, biliary, etc.) and/or placement of drainage tubes within 4 weeks before the study drug, related symptoms/signs must have substantially resolved, and no prophylactic/therapeutic use of antibiotics is required.
