Bendamustine with rituximab, etoposide and carboplatin (T(R)EC) in relapsed or refractory aggressive lymphoma: a prospective multicentre phase 1/2 clinical trial.

We sought to develop a safe and effective outpatient salvage regimen by replacing ifosfamide within the (R)ICE (rituximab, ifosfomide, carboplatin, etoposide) regimen with bendamustine (T(R)EC) via a multicentre phase I/II study for patients with relapsed or refractory diffuse large B cell lymphoma (DLBCL) and classic Hodgkin lymphoma (HL). Therapy consisted of 60-120 mg/m per day bendamustine on days 1 and 2 in combination with carboplatin, etoposide and rituximab (only for CD20 lymphoma) used in the (R)ICE regimen for up to 2 cycles. The objectives were to define a maximally tolerated dose (MTD) of bendamustine, determine safety and toxicity, assess efficacy, and evaluate impact on stem cell collection.

Results of a phase I-II study of fenretinide and rituximab for patients with indolent B-cell lymphoma and mantle cell lymphoma.

Fenretinide, a synthetic retinoid, induces apoptotic cell death in B-cell non-Hodgkin lymphoma (B-NHL) and acts synergistically with rituximab in preclinical models. We report results from a phase I-II study of fenretinide with rituximab for B-NHLs. Eligible diagnoses included indolent B-NHL or mantle cell lymphoma.

Brentuximab vedotin administered to platinum-refractory, transplant-naïve Hodgkin lymphoma patients can increase the proportion achieving FDG PET negative status.

Normalization of fluorodeoxyglucose positron emission tomography (FDG PET) imaging prior to high-dose therapy and autologous stem cell transplantation (ASCT) improves outcomes in relapsed and refractory (RR) Hodgkin lymphoma (HL), but many patients refractory to platinum-based salvage regimens are unable to achieve this goal. We therefore investigated whether brentuximab vedotin (BV) could normalize FDG PET in platinum-refractory HL prior to ASCT. Fifteen consecutive patients with RR HL and FDG PET positive disease after platinum-based salvage therapy were treated with a median of 4 cycles of BV.

A phase I study of pulse high-dose vorinostat (V) plus rituximab (R), ifosphamide, carboplatin, and etoposide (ICE) in patients with relapsed lymphoma.

Given the poor outcomes of relapsed aggressive lymphomas and preclinical data suggesting that ≥2·5 μmol/l concentrations of vorinostat synergize with both etoposide and platinums, we hypothesized that pulse high-dose vorinostat could safely augment the anti-tumour activity of (R)ICE [(rituximab), ifosphamide, carboplatin, etoposide] chemotherapy. We conducted a phase I dose escalation study using a schedule with oral vorinostat ranging from 400 mg/d to 700 mg bid for 5 d in combination with the standard (R)ICE regimen (days 3, 4 and 5). Twenty-nine patients [median age 56 years, median 2 prior therapies, 14 chemoresistant (of 27 evaluable), 2 prior transplants] were enrolled and treated.
