DZD8586 Combination Therapy in Patients With Diffuse Large B-cell Lymphoma (TAI-SHAN12)

Официальное название

A Phase Ib/II, Multicenter Study to Evaluate the Efficacy and Safety of DZD8586 Combination Therapy in Diffuse Large B-cell Lymphoma

Обзор

This study will treat patients with diffuse large B-cell lymphoma (DLBCL). It will assess the anti-tumor efficacy and safety of DZD8586 combination therapy by using objective response rate and the incidence and severity of adverse events. It will also measure the levels of DZD8586 in the body when combined with immunochemotherapy regimens.

• Disease stage II to IV by Ann Arbor Classification.
• Life expectancy ≥ 12 months.
• Cohort 2, 3:

• Pathologically confirmed DLBCL patients who have received adequate first-line treatment containing CD20 monoclonal antibody and anthracyclines (such as R-CHOP-like regimen).
• Relapsed or refractory to first-line R-CHOP-like regimen.
• For patients who have received only one line of therapy, if the patient has not received autologous stem cell transplantation, the investigator needs to assess as unsuitable or the patient refuses intensive chemotherapy and hematopoietic stem cell transplantation.
• Life expectancy ≥ 6 months.
• Patients must also meet all of the following criteria to be included in this study:

• All patients must provide a signed and dated written informed consent prior to any study-specific procedure, sampling, and analysis.
• Patients must be ≥ 18 years of age at the time of informed consent.
• ECOG status score of 0 to 2.
• Presence of at least one radiologically measurable lesion in 2 perpendicular directions as assessed by CT or MRI and a positive lesion on PET/CT scan consistent with a tumor site identified by CT or MRI.
• Adequate bone marrow hematopoietic reserve and organ function.
• No uncontrolled medical complications.
• Patients should be able to follow the relevant requirements of this study for medication and follow-up.
• Willing to comply with contraceptive restrictions.

Критерии исключения

• Cohort 2, 3:

a. Hematopoietic stem cell transplantation, cell therapy, or gene therapy within 90 days prior to first dose. Radiation therapy within 14 days prior to first dose. Chemotherapy and small-molecule targeted therapy were not terminated within 5 half-lives before the first dose; macromolecule drug therapy (such as antibody therapy) was not terminated within 28 days before the first dose.

• All patients should not be included in this study if they have any of the following conditions:

• Indolent lymphoma-transformed DLBCL, primary mediastinal lymphoma, lymphoma involving the central nervous system, or DLBCL with MYC and BCL2 rearrangements.
