Brief summary
Double-blind, randomized, placebo controlled phase 2 study to explore the efficacy and safety of HEM1036 in the treatment of subjects with LARS
Detailed description
The study will be conducted as a double-blind, randomized, placebo controlled phase 2 study to explore the efficacy and safety of HEM1036 in the treatment of subjects with LARS. Subjects will be males and females ≥18 and ≤75 years of age with LARS. Subjects must have a LARS score of \>20 at the Screening Visit after sphincter preserving rectal resection surgery for the curative treatment of diagnosed rectal cancer.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Low Anterior Resection Syndrome score from Baseline to 8 weeks | Baseline to 8 weeks | * Higher score means worse outcome * We will assess the change of LARS score at 8 weeks frome baseline. The change of LARS score of two treatment groups will be compared. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in QoL(Quality of Life) score from Baseline to 8 weeks | Baseline to 8 weeks | Score 0-100(higher score means better outcome) |
| Change in fecal microbiota composition assessed by alpha-diversity and differential abundance analysis | Baseline to 4, 8 weeks | — |
| Change of fecal metabolites assessed by fecal analysis | Baseline to 4, 8 weeks | Change of metabolites (including Total short-chain fatty acids, acetate, butyrate,propionate, lactate, bile acids in fecal samples) assessed by fecal analysis and all parameters will be presented as umol/g |
