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

ABSTRACT: Given the poor outcomes of relapsed aggressive lymphomas and preclinical data suggesting that ?2·5 ?mol/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. The maximally tolerated vorinostat dose was defined as 500 mg twice daily × 5 d. Common dose limiting toxicities included infection (n = 2), hypokalaemia (n = 2), and transaminitis (n = 2). Grade 3 related gastrointestinal toxicity was seen in 9 patients. The median vorinostat concentration on day 3 was 4·5 ?mol/l (range 4·2-6·0 ?mol/l) and in vitro data confirmed the augmented antitumour and histone acetylation activity at these levels. Responses were observed in 19 of 27 evaluable patients (70%) including 8 complete response/unconfirmed complete response. High-dose vorinostat can be delivered safely with (R)ICE, achieves potentially synergistic drug levels, and warrants further study, although adequate gastrointestinal prophylaxis is warranted.

Project description:BackgroundRelapsed or refractory classical Hodgkin lymphoma could be treated with multiagent salvage chemotherapy followed by autologous haematopoietic stem-cell transplantation. The aim of this study is to establish the safety and activity of dose-dense brentuximab vedotin combined with ifosfamide, carboplatin, and etoposide (BV-ICE) chemotherapy in second-line treatment of classical Hodgkin lymphoma.MethodsWe conducted a single-arm, open-label, phase 1/2 study of dose-dense BV-ICE at the Seattle Cancer Care Alliance, University of Washington (Seattle, WA, USA). Eligibility criteria were age 18 years or older; diagnosis of first relapse, primary refractory classical Hodgkin lymphoma after one previous line of therapy; measurable disease of at least 1 cm in the longest axis, CT of chest, abdomen, and pelvis with PET within the past 28 days; Eastern Cooperative Oncology Group performance status of 0-1; and adequate organ function. A 3 + 3 dose escalation study was done for the phase 1 part of the trial to establish the maximum tolerated dose to be used for the phase 2 study. Brentuximab vedotin was delivered on days 1 and 8 at either 1·2 mg/kg (dose level 1) or 1·5 mg/kg (dose level 2) intravenously (capped at 150 mg) with standard dosing of ICE on days 1-3 (ifosfamide 5 g/m2 plus mesna 5 g/m2 intravenously over 24 h on day 2, carboplatin area under the curve 5 on day 2 in one intravenous injection, and etoposide 100 mg/m2 on days 1-3 in one intravenous injection per day) for two 21-day cycles. The primary endpoint was to establish the recommended phase 2 dose (phase 1 part) and complete response rate after two cycles, with a prespecified target of 78% (phase 2 part). Safety analysis was done in all enrolled participants and the primary activity analysis was done in all patients with evaluable response data. This study is registered with ClinicalTrials.gov (NCT02227199); enrolment and study treatment are complete.FindingsBetween Oct 16, 2014, and Feb 10, 2020, we enrolled 45 patients with a median age of 31 years (IQR 28-45). The recommended phase 2 dose of brentuximab vedotin was established to be 1·5 mg/kg. After a median follow-up of 3·1 years (IQR 1·7-4·1), 32 (74%; 95% CI 58·8-86·5) of 43 evaluable patients had complete responses after two cycles of treatment. Grade 3-4 haematological toxic effects were common, including neutropenia (33 [73%]), anaemia (six [13%]), and thrombocytopenia (36 [80%]). The most common grade 3-4 non-haematological toxic effects were febrile neutropenia (four [9%]), sepsis (six [13%]), increased alanine aminotransferase (five [11%]), hyperglycaemia (three [7%]), pulmonary embolism (two [4%]), and increased aspartate aminotransferase (two [4%]). There was one (2%) on-treatment death due to multisystem organ failure that was considered treatment related. Serious adverse events occurred in 13 (29%) patients.InterpretationOur data suggest that dose-dense BV-ICE is a rapidly administered and active salvage regimen for patients with relapsed or refractory classical Hodgkin lymphoma despite a complete response in this trial lower than the prespecified phase 2 target. Although cross-trial comparisons should be made with caution, activity results seem to be similar to previously presented brentuximab vedotin chemotherapy salvage combinations delivered over much longer durations and can be considered in young (<60 years), transplantation-eligible patients for second-line therapy.FundingSeagen, Lymphoma Research Foundation, National Institutes of Health/National Cancer Institute, and generous philanthropic donations to the University of Washington from numerous individuals and families in support of lymphoma research.

Project description:BackgroundIn patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), salvage chemotherapy regimens (e.g., rituximab, ifosfamide, carboplatin, and etoposide, R-ICE) yield poor outcomes. Carfilzomib, an irreversible proteasome inhibitor, can overcome acquired rituximab-chemotherapy resistance and, when combined with R-ICE, improves outcomes in patients with R/R DLBCL.ObjectiveThis analysis aimed to develop a population pharmacokinetic/pharmacodynamic (PK/PD) model for carfilzomib in R/R DLBCL patients.Patients and methodsIn a single-center, open-label, prospective phase 1 study, patients received carfilzomib (10, 15, or 20 mg/m2) on days 1, 2, 8, and 9, and standard doses of R-ICE on days 3-6 every 21 days (maximum of three cycles). Carfilzomib plasma concentrations up to 24 h postinfusion were measured by liquid chromatography coupled with tandem mass spectrometry. Proteasome activity (PD biomarker) in peripheral blood mononuclear cells was assessed on days 1-2 with sparse sampling. PK/PD models were developed using NONMEM v7.4.1 interfaced with Finch Studio v1.1.0 and PsN v4.7.0. Model selection was guided by objective function value, goodness-of-fit, and visual predictive checks. Stepwise covariate modeling was used for covariate selection.ResultsTwenty-eight patients were enrolled in the PK/PD analysis, from whom 217 PK samples and 127 PD samples were included. Carfilzomib PK was best described by a two-compartment model with linear disposition (typical total clearance of 133 L/h). Proteasome activity was best characterized using a turnover model with irreversible inactivation. All parameters were estimated with good precision. No statistically significant covariates were identified.ConclusionsA validated population-based PK/PD model of carfilzomib was developed successfully. Further research is needed to identify sources of variability in response to treatment with carfilzomib in combination with R-ICE.Clinical trial registrationClinicalTrials.gov identifier number NCT01959698.
