This phase 2, randomised, double-blind, placebo-controlled trial evaluated the efficacy and safety of lebrikizumab, an interleukin-13 monoclonal antibody, alone or with background pirfenidone therapy, in patients with idiopathic pulmonary fibrosis (IPF).Patients with IPF aged ≥40 years with % predicted forced vital capacity (%FVC) 40%–100% and diffusing capacity for carbon monoxide 25%–90% and who were treatment-naive (Cohort A) or receiving pirfenidone (2403 mg·day−1; Cohort B) were randomised 1:1 to receive lebrikizumab 250 mg or placebo subcutaneously every 4 weeks. The primary endpoint was annualised rate of %FVC decline over 52 weeks.In Cohort A, 154 patients were randomised to receive lebrikizumab (n=78) or placebo (n=76). In Cohort B, 351 patients receiving pirfenidone were randomised to receive lebrikizumab (n=174) or placebo (n=177). Baseline demographics were balanced across treatment arms in both cohorts. The primary endpoint (annualised rate of %FVC decline) was not met in Cohort A (lebrikizumab versus placebo, −5.2% versus −6.2%; p=0.456) or Cohort B (lebrikizumab versus placebo, −5.5% versus −6.0%; p=0.557). In Cohort B, a non-statistically significant imbalance in mortality favouring combination therapy was observed (hazard ratio, 0.42 [95% CI, 0.17–1.04]). Pharmacodynamic biomarkers indicated lebrikizumab activity. The safety profile was consistent with that in previous studies of lebrikizumab and pirfenidone as monotherapies.Lebrikizumab alone or with pirfenidone was not associated with reduced %FVC decline over 52 weeks despite evidence of pharmacodynamic activity. Lebrikizumab was well tolerated with a favourable safety profile. These findings suggest that blocking IL-13 may not be sufficient to achieve a lung function benefit in patients with IPF.

6017 Background: In a single-arm, phase 2 study, we previously demonstrated that in pts with R/M HNSCC, cisplatin, docetaxel and E improved progression-free survival (PFS) compared to historical data (Kim et al., ASCO 2006). Herein, we evaluated this regimen in a single center, randomized, phase 2 trial. Methods: Pts with R/M HNSCC, with a performance status (PS) 0-2, were randomized (1:1) to receive up to 6 cycles of first-line chemotherapy with cisplatin 75 mg/m2 (or carboplatin AUC 6) and docetaxel 75 mg/m2 i.v. on day 1 every 21 days, plus placebo (P) vs. E 150 mg p.o. daily, followed by maintenance P or E until disease progression. The primary endpoint was PFS. With 120 pts, the study had 80% power to detect an improvement in median PFS from 3.0 to 4.9 months with a two-sided type I error rate of 0.1. Results: From 05/2010 to 07/2015, 120 pts were randomized to the P (N = 60) or E (N = 60) groups. All pts but one initiated treatment and were eligible for evaluation of the primary endpoint – 92 males; median age 62 years; 52 oropharynx, 40 oral cavity, 19 larynx, 8 hypopharynx cancer pts; 86 current/former smokers; 43 with recurrence within 6 months of completion of local treatment; 27 with prior exposure to EGFR inhibitors. Median PFS was 4.4 vs. 6.1 months for the P and E groups, respectively (hazard ratio [HR] 0.63, 95% confidence interval [CI] 0.42-0.95 months, p = 0.026). Response rates were 44% vs. 56% for P vs. E (p = 0.21). Median overall survival (OS) for P- and E-treated pts was 13.7 vs. 17.0 months (HR = 0.67, 95% CI 0.43-1.04, p = 0.07). Benefits from E on PFS and OS were more pronounced in pts with oropharyngeal tumors (p≤0.05 for interaction). In the E group, first-cycle rash grade 2-4 (34% pts) was associated with longer OS (HR = 0.40, p = 0.02). E-treated pts experienced a higher incidence of grade 3-4 adverse events (33.9 vs. 53.3%), including diarrhea (3 vs.17%), dehydration (5 vs. 15%), nausea (5 vs. 14%), rash (0 vs. 12%). Conclusions: This study met its primary endpoint. Addition of E to first-line platinum/docetaxel improved PFS and OS. This regimen may warrant further evaluation in randomized, phase 3 trials. Clinical trial information: NCT01064479.

Abstract Background: We aimed to investigate whether dextromethorphan (DM), an antitussive agent, could improve the antifibrotic efficacy of pirfenidone in treating idiopathic pulmonary fibrosis, a fatal interstitial lung disease characterized by progressive and irreversible respiratory failure.Methods: A bleomycin-induced mouse pulmonary fibrosis model study and an open-label randomized clinical trial were performed to evaluate the effectiveness of pirfenidone combined with DM.Results: In the animal study, pirfenidone combined with DM protected the mice against bleomycin-induced pulmonary fibrosis with better capabilities than pirfenidone or DM alone, as indicated by lung histologic analysis and hydroxyproline levels. In the clinical study, pirfenidone plus DM markedly mitigated pulmonary function (FEV1 and FVC) decline and ameliorated chest HRCT imaging scores (ground glass opacities and reticulation) of patients with IPF compared with pirfenidone alone at one year after administration. There were no significant differences in adverse reactions between the pirfenidone-DM group and the pirfenidone group.Conclusions: Pirfenidone plus DM may be a better strategy to modify IPF than pirfenidone alone. The efficacy and safety of the combination of pirfenidone and DM for patients with IPF warrants further verification by a double-blind randomized controlled trial (RCT).

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.
