Phase 2 double-blind, randomized trial of etravirine versus efavirenz in treatment-naive patients

TPS7576 Background: Follicular lymphoma (FL) is the most common subtype of indolent non-Hodgkin lymphoma. A limited number of chemotherapy-free options exist for patients with treatment-naïve (TN) FL who are older or who have comorbidities. Single-agent rituximab is considered a treatment option for elderly or infirm patients. In a phase 2 study, frontline treatment with ibrutinib in combination with rituximab for 4 weekly doses without maintenance resulted in an ORR of 85% (CR, 35%) with a median follow-up of 22 months and an 18-month PFS rate of 87% (Fowler Blood 2016). The phase 2 study serves as the basis for the randomized, double-blind, placebo-controlled phase 3 PERSPECTIVE (PCYC-1141-CA) trial. PERSPECTIVE will be conducted in two parts and will uniquely test (1) whether frontline treatment with ibrutinib in combination with rituximab results in prolongation of PFS compared to rituximab alone, and (2) whether continuous versus finite treatment with ibrutinib affects PFS outcomes. Methods: In the ongoing PERSPECTIVE trial, approximately 440 patients with TN FL meeting at least one Groupe d'Etude des Lymphomes Folliculaires (GELF) criterion will be randomized if they also meet one of the following criteria: age ≥70 years or age 60 to 69 with one or more comorbidities (creatinine clearance 30-59 mL/min or ECOG performance status of 2). Patients will be randomized to receive either ibrutinib or oral placebo once daily. All patients will be given rituximab for 4 weekly doses followed by maintenance. After at least 2 years of treatment in Part 1, patients randomized to ibrutinib who still remain on ibrutinib will be re-randomized in Part 2 to continue ibrutinib or switch to placebo. Key exclusion criteria include any prior treatment for FL, evidence of CNS involvement, or transformation. Analyses will be conducted in two distinct parts, both with a primary endpoint of PFS. The study is open for enrollment with sites planned in the US, EU, and Asia Pacific. Clinical trial information: NCT02947347.

Abstract Context Daily growth hormone (GH) injections can be burdensome for patients and carers. Somapacitan is a long-acting, reversible albumin-binding GH derivative in development for once-weekly administration in patients with growth hormone deficiency (GHD). Objective The objective of this study is to evaluate the efficacy, safety, and tolerability of once-weekly somapacitan vs once-daily GH. Design REAL 3 is a multicenter, randomized, controlled, double-blind (somapacitan doses), phase 2 study with a 26-week main and 26-week extension phase (NCT02616562). Setting This study took place at 29 sites in 11 countries. Patients Fifty-nine GH treatment-naive prepubertal children with GHD were randomly assigned; 58 completed the trial. Interventions Interventions comprised 3 somapacitan doses (0.04 [n = 16], 0.08 [n = 15], or 0.16 mg/kg/wk [n = 14]) and daily GH (0.034 mg/kg/d [n = 14]), administered subcutaneously. Main Outcome Measures The primary end point was height velocity (HV) at week 26. Secondary efficacy end points included HV SD score (SDS) and insulin-like growth factor-I (IGF-I) SDS. Results At week 26, mean (SD) annualized HV for the somapacitan groups was 8.0 (2.0), 10.9 (1.9), and 12.9 (3.5) cm/year, respectively, vs 11.4 (3.3) cm/year for daily GH; estimated treatment difference (somapacitan 0.16 mg/kg/week—daily GH): 1.7 [95% CI –0.2 to 3.6] cm/year. HV was sustained at week 52, and significantly greater with somapacitan 0.16 mg/kg/week vs daily GH. Mean (SD) change from baseline in HV SDS at week 52 was 4.72 (2.79), 6.14 (3.36), and 8.60 (3.15) for the somapacitan groups, respectively, vs 7.41 (4.08) for daily GH. Model-derived mean (SD) IGF-I SDS for the somapacitan groups was −1.62 (0.86), −1.09 (0.78), and 0.31 (1.06), respectively, vs −0.40 (1.50) observed for daily GH. Safety and tolerability were consistent with the profile of daily GH. Conclusions In children with GHD, once-weekly somapacitan 0.16 mg/kg/week provided the closest efficacy match with similar safety and tolerability to daily GH after 26 and 52 weeks of treatment.
