September 26, 2025 updated by: Fondazione Italiana Linfomi - ETS

PirtobrUtinib as Frontline Therapy for Elderly Unfit/Frail Patient With MAntle Cell Lymphoma: a Phase II Study of the Fondazione Italiana Linfomi (FIL)

This is a prospective, multicenter, phase II study, in elderly patients affected by Mantle cell lymphoma (MCL) defined as unfit/frail according to Simplified Geriatric Assessment (sGA) and previously untreated.

Patients will receive a treatment with Pirtobrutinib monotherapy until tumor progression, unacceptable adverse event, or patient decision for interruption.

Intervention / Treatment

Detailed Description

After providing written informed consent, patients will be evaluated for eligibility during a 28-day screening period. Patients will receive pirtobrutinib at a starting dose of 200 mg once daily (2 tablets q.d.). All treatment will be administered orally, and a cycle will be defined as 28 days in length and should be maintained regardless of dose interruptions. Treatment is meant to be administered until tumor progression, unacceptable adverse event, or patient decision for interruption.

Responses shall be assessed at month +3, +6 after start of treatment and then every 6 months using the radiologic method of tumor assessment consistent throughout the study and aligned with the baseline method (CT scan or ultrasound echography are acceptable). Positron Emission Tomography (PET) scan is mandatory at baseline and at month +3 after start of treatment to establish tumor response.

Health-Related Quality of Life Assessed by the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Questionnaire
Time Frame: 48 months
The EQ-5D-5L is a standardized instrument for measuring generic health status. It includes five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each with five levels. The outcome will be reported as the EQ-5D-5L index score. Higher scores indicate better health status.
48 months
Health-Related Quality of Life Assessed by the Functional Assessment of Cancer Therapy - Lymphoma (FACT-Lym) Questionnaire
Time Frame: 48 months
The FACT-Lym is a disease-specific instrument assessing quality of life in patients with lymphoma. It includes physical, social/family, emotional, and functional well-being, plus lymphoma-specific concerns. The outcome will be reported as the total FACT-Lym score. Higher scores indicate better quality of life.
