About

A Randomized Phase IIb Study, Evaluating Efficacy of Salvage Therapy with Brentuximab Vedotin-ESHAP vs ESHAP in Patients with Relapsed / Refractory Classical Hodgkin's Lymphoma, Followed by Brentuximab Vedotin Consolidation (instead of Autologous Hematopoietic Stem Cell Transplantation) in Those who Attained a Metabolic Complete Remission after Salvage Therapy

Full description

A phase IIb open label multi-center trial in patients with refractory / relapsed cHL.

Patients are randomized (1:1) to receive:

• ESHAP- BV (Etoposide [40 mg/m2/ day IV, D1-4], Solumedrol [250 mg/day IV, D1-4], high dose Ara-C [2 g/m2 IV, D5] and cisplatinum [25 mg/m2/day IV, D1-4] + BV [1.8 mg/kg IV, D1], every 21 days (3 cycles, q21 days).

Or

• ESHAP (Etoposide [40 mg/m2/ day IV, D1-4], Solumedrol [250 mg/day IV, D1-4], high dose Ara-C [2 g/m2 IV, D5] and cisplatinum [25 mg/m2/day IV, D1-4] (3 cycles, q21 days)

Stem cell collection will be performed in all patients according to institutional guidelines, but preferably after the first / second cycle of ESHAP-BV or ESHAP.

Patients attaining a mCR (Deauville 1, 2) after receiving 3 cycles of ESHAP-BV, will receive up to 13 cycles of BV consolidation (administered every 3 weeks, over 39 weeks).

Patients who were randomized to ESHAP and attained a mCR after receiving 3 cycles will receive up to 16 cycles of BV (same dosage and time intervals).

Patients who attained less than mCR following ESHAP-BV/ESHAP they will be taken out of the trial and will be treated according to their physician's clinical decision. However, they will be followed in order to evaluate their clinical outcome in terms of ORR, CR rate, TTNT2 and OS, that will be analyzed the study separately.

Enrollment: 150 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
