Effect of Regorafenib in Delaying Definitive Deterioration in Health-Related Quality of Life in Patients with Advanced Cancer of Three Different Tumor Types.

ABSTRACT:

Purpose

The efficacy and safety of regorafenib have been demonstrated in phase 3 trials for multiple tumor types, including metastatic colorectal cancer (mCRC) (CORRECT [NCT01103323]; CONCUR [NCT01584830]), advanced gastrointestinal stromal tumor (GIST) (GRID [NCT01271712]), and hepatocellular carcinoma (HCC) (RESORCE [NCT01774344]). The objective of this post hoc exploratory analysis was to explore the impact of regorafenib on delaying health-related quality of life (HRQOL) deterioration across these tumor types.

Patients and methods

HRQOL data (assessed with EORTC QLQ-C30 and EQ-5D questionnaires) were pooled for all trials to determine time until definitive deterioration (TUDD), defined as the patient's first minimal clinically important deterioration in HRQOL score from baseline that does not resolve, using stratified Kaplan-Meier estimators and Cox proportional hazards models adjusted for relevant trial, cancer type, and baseline covariates. Additional analyses based on cancer type were conducted by pooling mCRC trials (CORRECT and CONCUR) and pooling the two mCRC trials with the HCC trial (RESORCE).

Results

A total of 1699 patients with HRQOL data were pooled across the four trials. The results showed that regorafenib significantly delayed TUDD compared with placebo across all three tumor types. Median time to deterioration across the five scales ranged from 16.3 to 24.1 weeks for regorafenib and 8.6 to 12.1 weeks for placebo. The results from the individual studies, the pooled mCRC trials, and the pooled mCRC and HCC trials were similar to the overall pooled results.

Conclusion

A pooled analysis of four phase 3 trials demonstrated that regorafenib delayed a clinically relevant exploratory endpoint, defined as TUDD, compared with placebo across three different tumor types (mCRC, GIST, and HCC), which supports a novel benefit of the impact of regorafenib with respect to patients with these three types of cancers by allowing initial declines in HRQOL to resolve and patients the opportunity to continue treatment.

Project description:OBJECTIVES:There is little consensus regarding the prognostic value of symptom duration in predicting clinical disease severity or quality-of-life (QOL) outcomes in patients with chronic rhinosinusitis (CRS). Our objectives were to: 1) determine if patients with longer symptom duration have worse preoperative disease severity and/or QOL, and 2) determine if delayed surgical intervention influences outcomes of endoscopic sinus surgery (ESS). METHODS:Patients diagnosed with CRS were prospectively enrolled into a multicenter cohort study and observed 14.7 (standard deviaton {SD}?±?4.8) months on average following primary ESS. Preoperative symptom duration was stratified into short-term (<?12 months), middle-term (12-60 months), and long-term (>?60 months). Disease severity was assessed using endoscopy and computed tomography. Disease-specific QOL was measured with the 22-item Sinonasal Outcome Test (SNOT-22) and Rhinosinusitis Disability Index. Adjusted bivariate and multivariate associations between symptom duration, disease severity, and QOL scores were evaluated. RESULTS:One hundred and thirteen patients met inclusion criteria with 35 patients lost to postoperative follow-up. No significant differences in preoperative disease severity or QOL scores were reported between symptom duration subgroups. Participants in the long-term symptom subgroup reported significantly greater mean postoperative improvement on SNOT-22 total scores (n?=?28; -36.3[±?22.2]) compared to both short-term (n?=?27; -23.4[SD?±?11.3]; P?=?0.039) and middle-term (n?=?23; -23.5[SD?±?20.1]; P?=?0.050) subgroups. Postoperative QOL improvements in the long-term symptom subgroup remained significantly greater (P???0.036) after multivariate adjustment. CONCLUSIONS:Symptom duration was not associated with mean preoperative disease severity or QOL. Patients with long-term symptom duration reported the greatest mean postoperative QOL improvement, suggesting that delayed surgical intervention may not reduce QOL improvements following ESS.
