A Study of Brentuximab Vedotin and CHP in Frontline Treatment of PTCL With Less Than 10% CD30 Expression

• Status: Recruiting
• Trial end date: 2023-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This clinical trial will study brentuximab vedotin with CHP to find out if the drugs work for people who have certain types of peripheral T-cell lymphoma (PTCL). It will also find out what side effects occur when brentuximab vedotin and CHP are used together. A side effect is anything the drugs do besides treating cancer. CHP is a type of chemotherapy that uses three drugs (cyclophosphamide, doxorubicin, and prednisone). CHP is approved by the FDA to treat certain types of PTCL.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• The following non-sALCL PTCL subtypes are eligible:

• PTCL - not otherwise specified (PTCL-NOS)

• Angioimmunoblastic T-cell lymphoma (AITL)

• Adult T-cell leukemia/lymphoma (ATLL; acute and lymphoma types only, must be positive for human T cell leukemia virus 1)

• Enteropathy-associated T-cell lymphoma (EATL)

• Hepatosplenic T-cell lymphoma

• Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITCL)

• Indolent T-cell lymphoproliferative disorder (T-LPD) of the gastrointestinal (GI) tract

• Follicular T-cell lymphoma

• Nodal peripheral T-cell lymphoma with T-follicular helper (TFH) phenotype

• Fluorodeoxyglucose (FDG)-avid disease by PET and measurable disease of at least 1.5 cm by CT, as assessed by the site radiologist

• An Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2

Exclusion Criteria

• Current diagnosis of any of the following:

• sALCL

• Primary cutaneous T-cell lymphoproliferative disorders and lymphomas

• Mycosis fungoides (MF), including transformed MF

• History of another primary invasive cancer, hematologic malignancy, or myelodysplastic syndrome that has not been in remission for at least 3 years. Exceptions are malignancies with a negligible risk of metastasis or death (e.g., 5-year OS ≥90%), such as carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer.

• History of progressive multifocal leukoencephalopathy (PML).

• Cerebral/meningeal disease related to the underlying malignancy.

• Prior treatment with brentuximab vedotin or doxorubicin.

• Baseline peripheral neuropathy Grade 2 or higher (per the NCI CTCAE, Version 4.03) or subjects with the demyelinating form of Charcot-Marie-Tooth syndrome.

• Left ventricular ejection fraction less than 45% or symptomatic cardiac disease (including symptomatic ventricular dysfunction, symptomatic coronary artery disease, and symptomatic arrhythmias), or myocardial infarction within the past 6 months, or previous treatment with complete cumulative dose of >300 mg/m2 of doxorubicin.

• Any uncontrolled Grade 3 or higher (per the National Cancer Institute's Common Terminology Criteria for Adverse Events, NCI CTCAE Version 4.03) viral, bacterial, or fungal infection within 2 weeks prior to the first dose of study drug. Routine antimicrobial prophylaxis is permitted.
