This study was the prospective, multi-centered, double-blinded, randomized, parallel-group clinical study. The study investigated the efficacy and safety of LRG-002 investigational medicinal product, capsules (Lek d.d., Slovenia) in comparison with placebo, as an adjunct treatment for prophylaxis of antibiotic-associated diarrhea (AAD) in patients with acute respiratory diseases (ARDs) receiving a standard antimicrobial therapy.~The study comprised the following periods:~Study Periods Visit 1 (Day 1): Screening + randomization + initiation of treatment~Patients started participating in the study after signing the Informed Consent Form. Having completed screening tests, eligible patients were randomized on the same day to receive either LRG-002 or matching placebo capsules, each as an adjunct to the prescribed antibiotic. The treatment group was determined by randomization at a center ratio. Study subjects were supplied with the patient diary and blinded investigational product (investigational medicinal product or placebo) depending on the assigned treatment group. Patients could start study treatment only after receiving appropriate training. On Day 1, the study started in both groups from randomization and administration of the first dose of the investigational product depending on the assigned group after randomization:~Group T, treated with LRG-002: a single dose of 1 oral hard capsule taken during meals with some water; the product was to be taken orally 2 times per day for 14 days.~Group R, provided with placebo:a single dose of 1 oral hard capsule taken during meals with some water; the product is to be taken orally 2 times per day for 14 days.~Visit 2 (Day 7): Intermediate Follow-up Visit~Visit 3 (Day 15) : Visit 3 was scheduled at Day 15 when a patient was to come to the study site bringing along the completed diary, unused laboratory kit, unused product and empty packages.
The goal of this study was to investigate the efficacy and safety of LRG-002 investigational medicinal product, capsules (Lek d.d., Slovenia) in comparison with placebo, as an adjunct treatment for prophylaxis of antibiotic-associated diarrhea (AAD) in patients with acute respiratory diseases (ARDs) receiving a standard antimicrobial therapy.
