Efficacy and safety of sunitinib in elderly patients with metastatic renal cell carcinoma.

ABSTRACT: We retrospectively analyzed sunitinib outcome as a function of age in metastatic renal cell carcinoma (mRCC) patients.Data were pooled from 1059 patients in six trials. Kaplan-Meier estimates of progression-free survival (PFS) and overall survival (OS) were compared by log-rank test between patients aged <70 (n=857; 81%) and ?70 (n=202; 19%) years.In first-line patients, median PFS was comparable in younger and older patients, 9.9 vs 11.0 months, respectively (HR, 0.89; 95% CI: 0.73-1.09; P=0.2629), as was median OS, 23.6 vs 25.6 months (HR, 0.93; 95% CI: 0.74-1.18; P=0.5442). Similarly, in cytokine-refractory patients, median PFS was 8.1 vs 8.4 months (HR, 0.79; 95% CI: 0.49-1.28; P=0.3350), while median OS was 20.2 vs 15.8 months (HR, 1.14; 95% CI: 0.73-1.79; P=0.5657). Some treatment-emergent adverse events were significantly less common in younger vs older patients, including fatigue (60% vs 69%), cough (20% vs 29%), peripheral edema (17% vs 27%), anemia (18% vs 25%), decreased appetite (13% vs 29%), and thrombocytopenia (16% vs 25%; all P<0.05). Hand-foot syndrome was more common in younger patients (32% vs 24%).Advanced age should not be a deterrent to sunitinib therapy and elderly patients may achieve additional clinical benefit.

<h4>Background</h4>We retrospectively analyzed sunitinib outcome as a function of age in metastatic renal cell carcinoma (mRCC) patients.<h4>Methods</h4>Data were pooled from 1059 patients in six trials.

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.

Project description:BACKGROUND:Sunitinib is an approved treatment for metastatic renal cell carcinoma (mRCC). The safety profile and efficacy of sunitinib were confirmed in a global expanded access trial (ClinicalTrials.gov identifier: NCT00130897). This report presents a subanalysis of the final trial data from patients in Latin America. METHODS:Treatment-naïve or previously treated mRCC patients aged ?18 years received oral sunitinib at a starting dose of 50 mg/day on a 4-weeks-on/2-weeks-off schedule. Treatment continued until disease progression, unacceptable toxicity, or withdrawal of consent. Safety was assessed regularly, and tumor measurements were scheduled per local practice (using Response Evaluation Criteria in Solid Tumors). RESULTS:In total, 348 patients from Latin America received sunitinib. Overall, 75% of patients had two or more sites of metastatic disease, 28% were aged ?65 years, 14% had an Eastern Cooperative Oncology Group performance status ?2, 9% had brain metastases, 9% had no prior nephrectomy, and 5% had non-clear cell RCC. Median treatment duration was 8 months, and median follow-up was 15.1 months. In total, 326 patients (94%) discontinued treatment, primarily due to death (41%) or lack of efficacy (22%). Most treatment-related adverse events were of mild to moderate severity (grade 1/2). Mucosal inflammation (reported in 54% of patients), diarrhea (53%), and asthenia (41%) were the most common any-grade treatment-related adverse events. Asthenia (12%), neutropenia (10%), and fatigue and thrombocytopenia (both 9%) were the most common grade 3/4 treatment-related adverse events. In total, 311 patients were included for tumor response, of whom eight (3%) had a complete response and 46 (15%) a partial response, yielding an objective response rate of 17%. Median duration of response, progression-free survival, and overall survival were 26.7, 12.1, and 16.9 months, respectively. CONCLUSION:The efficacy and safety profile of sunitinib in patients with mRCC from Latin America was comparable to that in the entire cohort of the global expanded access trial.

Project description:BackgroundElderly patients with metastatic renal cell carcinoma (mRCC) may require special treatment considerations, particularly when comorbidities are present. An understanding of the efficacy and safety of targeted agents in elderly patients with mRCC is essential to provide individualized therapy.ObjectiveTo evaluate the efficacy and safety of everolimus in elderly patients (those ≥ 65 and ≥ 70 yr of age) enrolled in RECORD-1.Design, setting, and participantsThe multicenter randomized RECORD-1 phase 3 trial (Clinicaltrials.gov identifier, NCT00410124; http://www.clinicaltrials.gov) enrolled patients with mRCC who progressed during or within 6 mo of stopping sunitinib and/or sorafenib treatment (n=416).InterventionEverolimus 10mg once daily (n=277) or placebo (n=139) plus best supportive care. Treatment was continued until disease progression or unacceptable toxicity.MeasurementsMedian progression-free survival (PFS), median overall survival (OS), and time to deterioration in Karnofsky performance status (TTD-KPS) were assessed using the Kaplan-Meier method; the log-rank test was used to compare treatment arms. Other outcomes evaluated included reduction in tumor burden, overall response rate (ORR), and safety.Results and limitationsIn RECORD-1, 36.8% of patients were ≥ 65 yr and 17.5% were ≥ 70 yr of age. PFS, OS, TTD-KPS, reduction in tumor burden, and ORR were similar in the elderly and the overall RECORD-1 population. Everolimus was generally well tolerated in elderly patients, and most adverse events were grade 1 or 2 in severity. The toxicity profile of everolimus was generally similar in older patients and the overall population; however, peripheral edema, cough, rash, and diarrhea were reported more frequently in the elderly regardless of treatment. The retrospective nature of the analyses was the major limitation.ConclusionsEverolimus is effective and tolerable in elderly patients with mRCC. When selecting targeted therapies in these patients, the specific toxicity profile of each agent and any patient comorbidities should be considered.
