Effects of subsequent systemic anticancer medication following first-line lenvatinib: a post hoc responder analysis from the phase 3 REFLECT study in unresectable hepatocellular carcinoma

Introduction: Understanding the relationship between subsequent-line therapies and overall survival (OS) is important for maximizing OS for patients with hepatocellular carcinoma. Objective: In this post hoc analysis, we investigated OS in lenvatinib- and sorafenib-treated patients from the REFLECT study, who then received subsequent anticancer medication during the survival follow-up period. Methods: The follow-up period commenced at the first off-treatment visit after stopping the study medication and continued until study termination, withdrawal of consent, or death. OS and objective response rate were calculated for patients who did or did not receive poststudy anticancer medication for both treatment arms, as well as for the overall cohort. We investigated the subset of patients who responded to first-line treatment and subsequently received anticancer medication. Results: The OS for patients initially randomized to first-line lenvatinib (versus first-line sorafenib) and who then received any subsequent anticancer medication was 20.8 vs. 17.0 months (hazard ratio [HR] 0.87; 95% CI 0.67–1.14). The OS for patients who initially received first-line lenvatinib (versus first-line sorafenib) and who did not receive any subsequent anticancer medication was 11.5 vs. 9.1 months (HR 0.90; 95% CI 0.75–1.09). Responders to first-line lenvatinib who received subsequent medication had a median OS of 25.7 months (95% CI 18.5–34.6); responders to first line-sorafenib who received subsequent medication had a median OS of 22.3 months (95% CI 14.6–not evaluable). Conclusions: In this post hoc analysis of all patients in the REFLECT study who received subsequent anticancer medication, OS was increased compared with patients who did not receive any subsequent anticancer medication. In a subset analysis of responders who had received subsequent anticancer medication, use of first-line lenvatinib led to a slightly longer median OS; more research is needed on the benefits of using first-line lenvatinib compared with sorafenib

Clinical effects of colesevelam in hispanic subjects with primary hyperlipidemia and prediabetes

Objective: To evaluate the efficacy and safety of colesevelam in Hispanic subjects with primary hyperlipidemia and prediabetes. Materials and Methods: A 16-week, randomized, double-blind, placebo-controlled, multinational study evaluating colesevelam in participants with primary hyperlipidemia (low-density lipoprotein cholesterol [LDL-C] level > 100 mg/dL) and prediabetes (fasting plasma glucose level > 110 to less than 125 mg/dL, or 2-hour postload glucose level > 140 to less than 200 mg/dL during an oral glucose tolerance test) was conducted between January 14, 2008 and April 3, 2009. Participants were randomized 1:1 to colesevelam 3.75 g/day or placebo. The primary efficacy endpoint was mean change from baseline in LDL-C level with colesevelam compared with placebo. Participants who self-identifed as Hispanic during enrollment were included in this exploratory analysis evaluating the effcacy of colesevelam in Hispanics with primary hyperlipidemia and prediabetes. Results: From a total of 216 subjects with primary hyperlipidemia and prediabetes, 153 Hispanics were included in this post hoc analysis; 77 subjects were randomized to colesevelam and 76 subjects were randomized to placebo. At week 16, LDL-C levels were significantly reduced with colesevelam compared with placebo (mean treatment difference, -19.4%; P less than 0.0001). Achievement of LDL-C level less than 100 mg/dL was more frequent with colesevelam than with placebo (27% vs 11%; P = 0.002). In addition, significant mean reductions in non-high-density lipoprotein cholesterol, total cholesterol, and apolipoprotein B levels (P less than 0.0002 for all), and a significant median increase in triglyceride levels (P = 0.003), were seen with colesevelam compared with placebo. At study end, there was a significant mean reduction in glycated hemoglobin levels and median reduction in fasting plasma glucose levels with colesevelam compared with placebo (P less than 0.02 for both). A fasting plasma glucose level less than 100 mg/dL was achieved in 44% of colesevelam recipients compared with 23% of placebo recipients (P less than 0.05). Overall, colesevelam was well tolerated. Conclusion: Colesevelam may be a treatment option for Hispanic subjects with primary hyperlipidemia and prediabetes, mainly to reduce LDL-C levels, with added beneficial effect on glucose levels. © Postgraduate Medicine
