Phase 2 trial of linifanib (ABT-869) in patients with advanced renal cell cancer after sunitinib failure.

ABSTRACT: This study assessed the efficacy and safety of linifanib in patients with advanced renal cell carcinoma (RCC) who were previously treated with sunitinib.This open-label, multicentre, phase 2 trial of oral linifanib 0.25 mg/kg/day enrolled patients who had prior nephrectomy and adequate organ function. The primary end-point was objective response rate (ORR) per response evaluation criteria in solid tumors (RECIST) by central imaging. Secondary end-points were progression-free survival (PFS), overall survival (OS) and time to progression (TTP). Safety was also assessed.Fifty-three patients, median age 61 years (range 40-80) were enrolled (August 2007 to October 2008) across 12 North-American centres. Median number of prior therapies was 2 (range 1-4); 43 patients (81%) had clear-cell histology. ORR was 13.2%, median PFS was 5.4 months (95% Confidence Interval (CI): 3.6, 6.0) and TTP was the same; median OS was 14.5 months (95% CI: 10.8, 24.1). The most common treatment-related adverse events (AEs) were diarrhoea (74%), fatigue (74%) and hypertension (66%), and the most common treatment-related Grade 3/4 AE was hypertension (40%).Linifanib demonstrated clinically meaningful activity in patients with advanced RCC after sunitinib failure. At 0.25 mg/kg/day, significant dose modifications were required. An alternative, fixed-dosing strategy is being evaluated in other trials.

Project description:Sunitinib is a standard-of-care treatment in advanced clear cell renal cell carcinoma (ccRCC). Retrospective and expanded access data suggest sunitinib has activity in advanced non-clear cell renal cell carcinoma (nccRCC).To prospectively determine the clinical efficacy and safety of sunitinib in patients with advanced nccRCC.This is a single-arm phase 2 trial with a two-stage design. Eligibility criteria included pathologically confirmed nccRCC or ccRCC with ? 20% sarcomatoid histology, performance status 0-2, measurable disease, a maximum of two prior systemic therapies, and no prior treatment with tyrosine kinase inhibitors directed against the vascular endothelial growth factor receptors.Patients received sunitinib 50mg daily on a 4-wk on, 2-wk off schedule.Primary end points were objective response rate (ORR) and progression-free survival (PFS). Secondary end points were safety and overall survival (OS).Fifty-seven patients were eligible (nccRCC histology: papillary, 27; chromophobe, 5; unclassified, 8; collecting duct or medullary carcinoma, 6; sarcomatoid, 7; and others, 4). Median PFS for 55 evaluable patients was 2.7 mo (95% confidence interval [CI], 1.4-5.4). Two patients with chromophobe and one patient with unclassified histology had a confirmed partial response (5% ORR). Median PFS for patients with papillary histology was 1.6 mo (95% CI, 1.4-5.4). Median PFS for patients with chromophobe histology was 12.7 mo (95% CI, 8.5-NA). Median OS for all patients was 16.8 mo (95% CI, 10.7-26.3). Treatment-emergent adverse events were consistent with sunitinib's mechanism of action. The nonrandomized design and small number of patients are limitations of this study.The differential response of chromophobe histology to sunitinib suggests a therapeutically relevant biological heterogeneity exists within nccRCC. The low ORR and short PFS with sunitinib in the other nccRCC subtypes underscore the need to enroll patients with these diverse tumors in clinical trials.

Project description:BackgroundIn the ongoing phase 3, CheckMate 214 trial, nivolumab plus ipilimumab improved overall survival compared with sunitinib in patients with intermediate or poor risk, previously untreated, advanced renal cell carcinoma. We aimed to assess whether health-related quality of life (HRQoL) could be used to further describe the benefit-risk profile of nivolumab plus ipilimumab versus sunitinib.MethodsIn the phase 3, randomised, controlled, CheckMate 214 trial, patients aged 18 years and older with previously untreated, advanced or metastatic renal cell carcinoma with a clear-cell component were recruited from 175 hospitals and cancer centres in 28 countries. Patients were categorised by risk status into favourable, intermediate, and poor risk subgroups and randomly assigned (1:1) to open-label nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for four doses followed by nivolumab 3 mg/kg every 2 weeks, or sunitinib 50 mg/day for 4 weeks of each 6-week cycle. Randomisation was done with a block size of four and stratified by risk status and geographical region. Patient-reported outcomes (PROs) were assessed using the Functional Assessment of Cancer Therapy Kidney Symptom Index-19 (FKSI-19), Functional Assessment of Cancer Therapy-General (FACT-G), and EuroQol five dimensional three level (EQ-5D-3L) instruments. The coprimary endpoints of the trial, reported previously, were overall survival, progression-free survival, and the proportion of patients who had an objective response in those categorised as at intermediate or poor risk. PROs in all randomised participants were assessed as an exploratory endpoint; here we report this exploratory endpoint. This study is registered with ClinicalTrials.gov, number NCT02231749, and is ongoing but is now closed to recruitment.FindingsBetween Oct 16, 2014, and Feb 23, 2016, of 1390 patients screened, 1096 (79%) were randomly assigned to treatment, of whom 847 (77%) were at intermediate or poor risk and randomly assigned to nivolumab plus ipilimumab (n=425) or sunitinib (n=422). Median follow-up was 25·2 months (IQR 23·0-27·4). PROs were more favourable with nivolumab plus ipilimumab than sunitinib throughout the first 103 weeks after baseline, with mean change from baseline at week 103 for FKSI-19 total score being 4·00 (95% CI 1·91 to 6·09) for nivolumab plus ipilimumab versus -3·14 (-6·03 to -0·25) for sunitinib (p<0·0001), and for FACT-G total score being 4·77 (1·73 to 7·82) for nivolumab plus ipilimumab versus -4·32 (-8·54 to -0·11) for sunitinib (p=0·0005). Significant differences were also seen for four of five FKSI-19 domains (disease-related symptoms, physical disease-related symptoms, treatment side-effects, and functional wellbeing) and FACT-G physical and functional wellbeing domains. However, there was no significant difference between the treatment groups at week 103 in EQ-5D-3L visual analogue rating scale (VAS) scores, with mean change from baseline to week 103 of 10·07 (95% CI 4·35 to 15·80) for nivolumab plus ipilimumab and 6·40 (-1·36 to 14·16) for sunitinib (p=0·45). Compared with sunitinib, nivolumab plus ipilimumab reduced risk of deterioration in FKSI-19 total score (hazard ratio [HR] 0·54; 95% CI 0·46-0·63), FACT-G total score (0·63, 0·52-0·75), and EQ-5D-3L VAS score (HR 0·75, 95% CI 0·63-0·89) and UK utility scores (0·67, 0·57-0·80).InterpretationNivolumab plus ipilimumab leads to fewer symptoms and better HRQoL than sunitinib in patients at intermediate or poor risk with advanced renal cell carcinoma. These results suggest that the superior efficacy of nivolumab plus ipilimumab over sunitinib comes with the additional benefit of improved HRQoL.FundingBristol-Myers Squibb and ONO Pharmaceutical.
