LBA12007 Background: Cancer cachexia arises from the interaction between the host and the tumour, triggering an inflammatory response that leads to weight and appetite loss, diminished physical activity, reduced treatment efficacy and survival. Combining interventions to address inflammation, weight loss, and physical activity is proposed as an effective strategy. Building on a promising pilot study, we conducted the MENAC (Multimodal Exercise Nutrition Anti-inflammatory Cachexia) trial to comprehensively evaluate this approach in patients with lung and pancreatic cancer undergoing systemic anti-cancer treatment (SACT). Methods: MENAC was an investigator-initiated, multicentre, open label, randomised phase 3 trial conducted at 17 sites in 4 countries. Patients with stage III or IV lung or pancreatic cancer receiving SACT with non-curative intent were randomly assigned (1:1) to a multimodal intervention consisting of nutritional counselling plus fish oil containing oral nutritional supplements, physical exercise [endurance and strength] and non-steroidal anti-inflammatory drugs [NSAIDs]) versus standard care. Randomisation was stratified by country, cancer type and stage. Primary Objective: To assess differences between arms in change in body weight. Secondary Objectives: To assess differences in muscle mass (measured by CT L3 technique) and physical activity (assessed through step counts using ActivPAL activity meter) between arms. Assessments were conducted at basline (pre-randomisation) and at endpoint (after 6 weeks). Results: From May 2015 to February 2022, 212 patients were enrolled (105 to multimodal treatment, 107 standard care). Over 6 weeks, weight stabilised in patients assigned to multimodal treatment compared with those assigned to standard care (mean weight change [SD] 0.05 kg [3.8] vs – 0.99 kg [3.2], respectively) with a mean difference in weight change of -1.04, 95 % CI -2.02 to -0.06, p=0.04. There was no conclusive difference in muscle mass (mean change [SD] -6.5cm2 [ 10.1] vs -6.3cm2 [11.9], p=0.93) or in mean step counts [SD] (-377.7 [2075] vs -458 [1858], p=0.89). There were 28 and 24 reported SAEs in the intervention and control arm respectively, no SUSARs were reported. Conclusions: A multimodal cachexia intervention stabilised weight compared to standard care at six weeks. There was no difference in physical activity or muscle mass between trial arms.
