Adjuvant sunitinib in patients with high-risk renal cell carcinoma: safety, therapy management, and patient-reported outcomes in the S-TRAC trial.

ABSTRACT: Background:Adjuvant sunitinib has significantly improved disease-free survival versus placebo in patients with renal cell carcinoma at high risk of recurrence post-nephrectomy (hazard ratio 0.76; 95% confidence interval, 0.59-0.98; two-sided P?=?0.03). We report safety, therapy management, and patient-reported outcomes for patients receiving sunitinib and placebo in the S-TRAC trial. Patients and methods:Patients were stratified by the University of California, Los Angeles Integrated Staging System and Eastern Cooperative Oncology Group performance status score, and randomized (1 : 1) to receive sunitinib (50?mg/day) or placebo. Single dose reductions to 37.5?mg, dose delays, and dose interruptions were used to manage adverse events (AEs). Patients' health-related quality of life, including key symptoms typically associated with sunitinib, were evaluated with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Results:Patients maintained treatment for 9.5 (mean, SD 4.4) and 10.3 (mean, SD 3.7) months in the sunitinib and placebo arms, respectively. In the sunitinib arm, key AEs occurred ?1?month (median) after start of treatment and resolved within ?3.5?weeks (median). Many (40.6%) AEs leading to permanent discontinuation were grade 1/2, and most (87.2%) resolved or were resolving by 28?days after last treatment. Patients taking sunitinib showed a significantly lower EORTC QLQ-C30 overall health status score versus placebo, although this reduction was not clinically meaningful. Patients reported symptoms typically related to sunitinib treatment with diarrhea and loss of appetite showing clinically meaningful increases. Conclusions:In S-TRAC, AEs were predictable, manageable, and reversible via dose interruptions, dose reductions, and/or standard supportive medical therapy. Patients on sunitinib did report increased symptoms and reduced HRQoL, but these changes were generally not clinically meaningful, apart from appetite loss and diarrhea, and were expected in the context of known sunitinib effects.

Project description:ObjectiveTo evaluate patient-reported outcome (PRO) data from the IMmotion150 study. The phase 2 IMmotion150 study showed improved progression-free survival with atezolizumab plus bevacizumab vs sunitinib in patients with programmed death-ligand 1 (PD-L1)+ tumours and suggested activity of atezolizumab monotherapy in previously untreated metastatic renal cell carcinoma (mRCC).Patients and methodsPatients with previously untreated mRCC were randomised to atezolizumab 1200 mg intravenously (i.v.) every 3 weeks (n = 103), the atezolizumab regimen plus bevacizumab 15 mg/kg i.v. every 3 weeks (n = 101), or sunitinib 50 mg orally daily (4 weeks on, 2 weeks off; n = 101). The MD Anderson Symptom Inventory (MDASI) and Brief Fatigue Inventory (BFI) were administered on days 1 and 22 of each 6-week cycle. Time to deterioration (TTD), change from baseline in MDASI core and RCC symptom severity, interference with daily life, and BFI fatigue severity and interference scores were reported for all comers. The TTD was the first ≥2-point score increase over baseline. Absolute effect size ≥0.2 suggested a clinically important difference with checkpoint inhibitor therapy vs sunitinib.ResultsCompletion rates were >90% at baseline and ≥80% at most visits. Delayed TTD in core and RCC symptoms, symptom interference, fatigue, and fatigue-related interference was observed with atezolizumab (both alone and in combination) vs sunitinib. Improved TTD (hazard ratio [HR], 95% confidence interval [CI]) was more pronounced with atezolizumab monotherapy: core symptoms, 0.39 (0.22-0.71); RCC symptoms, 0.22 (0.12-0.41); and symptom interference, 0.36 (0.22-0.58). Change from baseline by visit, evaluated by the MDASI, also showed a trend favouring atezolizumab monotherapy vs sunitinib. Small sample sizes may have limited the ability to draw definitive conclusions.ConclusionPROs suggested that atezolizumab alone or with bevacizumab maintained daily function compared with sunitinib. Notably, symptoms were least severe with atezolizumab alone vs sunitinib (IMmotion150; ClinicalTrials.gov Identifier: NCT01984242).

Project description:BACKGROUND:In 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. METHODS:In 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. FINDINGS:Between 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). INTERPRETATION:Nivolumab 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. FUNDING:Bristol-Myers Squibb and ONO Pharmaceutical.

Project description:BackgroundMetastatic renal cell carcinoma (mRCC) patients receiving first-line sunitinib typically survive >2 yr, with chronic treatment sometimes extending to ≥6 yr.ObjectiveTo analyze long-term safety with sunitinib in mRCC patients.Design, setting, and participantsData were pooled from 5739 patients in nine trials, comprising seven phase II studies, a phase III study, and an expanded-access trial in various treatment settings (e.g., cytokine refractory or treatment-naïve).Outcome measurements and statistical analysisInterval and cumulative time-period analyses evaluated the incidence of treatment-related adverse events (TRAEs) for up to 6 yr, in the overall population and in those with long-term (≥2 yr) sunitinib treatment.Results and limitationsAmong long-term patients (n=807), most TRAEs occurred initially in the first year and then decreased in frequency; TRAEs following this pattern included decreased appetite, diarrhea, dysgeusia, dyspepsia, fatigue, hypertension, mucosal inflammation, nausea, and stomatitis. However, hypothyroidism increased by interval analysis from 6% at 0-<6 mo to 42% at 5-<6 yr and by cumulative analysis from 14% at 0-<1 yr to 36% over 6 yr. Grade 3/4 TRAEs in long-term patients peaked during the first year and then steadily decreased. The overall population displayed only minor differences from long-term patients, with no clinically significant differences between grade ≥3 TRAE profiles (<5% difference in incidence rates at all intervals). Limitations included retrospective design, assessment variability, lack of pharmacokinetic data, and absence of baseline characteristics for long-term patients.ConclusionsProlonged sunitinib was not associated with new types or increased severity of TRAEs. Except hypothyroidism, toxicity was not cumulative.Patient summaryMore than 800 mRCC patients received sunitinib for between 2 and 6 yr without experiencing new or more severe treatment-related toxicity. Clinicians may be able to prescribe chronic sunitinib treatment for as long as patients continue to derive clinical benefit, without untoward additional risk.
