Background
Many patients (pts) with advanced RCC have comorbidities (particularly elderly pts), but pts with comorbidities are often underrepresented in clinical trials. PREDICT (NCT 00895674) was a large, non-interventional study of sorafenib (Sor) in pts with advanced RCC in clinical practice. We report findings in pts with baseline comorbidities.
Methods
Pts diagnosed with advanced RCC and prescribed Sor under compliance of the local product label were eligible. Physician assessments of efficacy and tolerability were collected for ≤12 months.
Results
The most frequent comorbidities were hypertension (HTN; n = 674) and diabetes (n = 225); baseline characteristics in these pts (71–73% male, 82–87% prior nephrectomy, 82–83% clear cell histology) were similar to the total efficacy population (n = 2311; 71% male, 84% prior nephrectomy, 83% clear cell histology). Pts with HTN (38%; n = 254) and diabetes (38%; n = 85) were more likely to be aged ≥70 years vs the total efficacy population (23%; n = 532). Median duration of therapy (DOT) in pts with HTN (6.7 months) or diabetes (7.0 months) was similar to the total efficacy population (7.3 months). A similar trend was seen for all pts aged ≥70 years (median DOT: total efficacy population, 6.1 months; HTN subset, 6.0 months; diabetes subset, 6.4 months). Best tumor response per RECIST was similar in the total group (complete response [CR], 2%; partial response [PR], 22%; stable disease [SD], 47%; and progressive disease [PD], 4%) and comorbid groups (CR, 1–2%; PR, 22–23%; SD, 43–48%; PD, 4–5%). In general, adverse event (AE) rates were slightly higher in pts with comorbidities than in the total safety population (Table).
Conclusions
In pts with RCC treated in clinical practice settings, some AE rates were numerically higher in pts with comorbidities. There were no notable differences in duration of Sor therapy. Number (%) pts with AEs (safety population)
