Objective: Obesity is a major public health issue with significant impact on quality of life, morbidity and mortality rates. It is estimated that if the current trends continue, 18% of men and 21% of women worldwide will be obese by 2025. All the current therapies are not optimal due to limited efficacy or safety; thus, there is a need for additional devices for the treatment of obesity. This study aimed to examine the safety, tolerability, and efficacy of a biodegradable encapsulated Epitomee device for weight loss. The technology is based on absorbent pharmaceuticals polymers and bonding materials that self-expand in the stomach to create a pH-sensitive super absorbent gel structure for weight loss. Methods: A prospective, 12-week twice daily use of the encapsulated device in patients with body mass index of 27–40 kg m−2. Efficacy endpoints were the percent total body weight loss (%TBWL), proportion of participants with 5% TBWL and changes in cardio-metabolic markers. Safety analysis included evaluation of adverse events, laboratory and endoscopic findings. Results: Overall, 52 patients completed the study. TBWL per intension-to-treat analysis was 3.68 ± 3.07% (3.23 ± 2.69 kg) and 4.52 ± 2.97% (3.95 ± 2.57 kg) per protocol. No device serious adverse effects reported. The most common adverse events were headache (18.1%), viral infection (11.5%), abdominal discomfort (10.1%), bloating (7.9%), nausea and constipation (5% each) and flatulence (4.3%). Endoscopy in 26 patients revealed mild, asymptomatic gastric/duodenal erythema without erosions in five patients. Conclusions: Twelve weeks of Epitomee capsules treatment combined with lifestyle counselling resulted in 3.68–4.52% of TBWL. With continued research, the Epitomee capsules have considerable potential to become a non-invasive, safe and effective treatment option for weight loss.
