P1.06-003 - Anamorelin in Cachectic Patients with Advanced NSCLC, a Post-Hoc Pooled Efficacy Data Analysis of Two Phase 3 Trials (ID 4878)

- Abstract
Background:
Anorexia-cachexia is a multifactorial syndrome frequently experienced by patients with non-small cell lung cancer (NSCLC). It is characterized by decreased body weight (mainly due to muscle loss) and is associated with worsen morbidity, poor tolerance of chemotherapy and reduced survival. The randomized, double-blind ROMANA 1 and ROMANA 2 phase 3 trials in cachectic NSCLC patients, demonstrated that the ghrelin receptor agonist anamorelin was well tolerated, improved body weight, lean body mass (LBM), fat mass (FM) and anorexia/cachexia symptoms and concerns, with no difference in handgrip strength compared to placebo. Here we assessed pooled efficacy and numbers needed to treat (NNT) from ROMANA 1 and ROMANA 2 studies.
Methods:
Stage III/IV NSCLC patients with cachexia (≥5% weight loss during prior 6 months or BMI<20 kg/m[2]) were randomized (2:1) to daily oral 100 mg anamorelin or placebo for 12 weeks. Endpoints included changes in LBM, FM, total body mass (TBM) and in self-reported anorexia/cachexia symptoms and concerns. We present the pooled efficacy data from a post-hoc analysis from both trials (anamorelin, N=552; placebo, N=277); treatment differences, 95% CI, NNT and nominal p values from baseline to end of study.
Results:
At the end of study, compared with placebo, anamorelin-treated patients significantly increased body composition parameters (LBM, appendicular LBM, FM and TBM), and a greater proportion of patients showed improvements in these parameters (Table). The anamorelin group also significantly improved anorexia/cachexia symptoms and concerns, and compared to placebo, more patients in the anamorelin arm achieved the minimally important difference of 4 points. Figure 1
Conclusion:
Anamorelin has anabolic activity while improving symptom burden in cachectic patients with NSCLC. A significantly greater proportion of patients increased lean mass, fat mass and improved anorexia/cachexia symptoms and concern score in the anamorelin arm versus the placebo arm, with favorable NNT.
