Brief summary
A Phase 2b Randomized, Double-blind, Placebo-controlled, Study to Evaluate the Efficacy and Safety of MEDI3506 in Subjects with Diabetic Kidney Disease
Detailed description
This is a Phase 2b, randomized, double-blind, placebo-controlled, multicenter study to evaluate the efficacy, safety, PK, and immunogenicity of MEDI3506 on top of standard of care, including angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) and dapagliflozin in adult subjects with diabetic kidney disease, defined as subjects with type 2 diabetes mellitus (T2DM) and an estimated glomerular filtration rate (eGFR) of 25-75 mL/min/1.73 m2 with a UACR in the range of 100-3000 mg/g, who meet all eligibility criteria. Approximately 565 subjects, among multiple countries will be randomized to MEDI3506 dose 1, 2, 3 or dose 4, or placebo during a treatment period of 24 weeks. All subjects will receive Dapagliflozin daily, as administered orally from Day 85 to Day 168. The primary objective is to evaluate the effect of MEDI3506 on albuminuria in subjects with DKD. Secondary objectives include evaluating safety, PK and the incidence of ADA during the treatment period.

Masking description
This is a double-blinded study in which MEDI3506 and placebo. Neither the subject nor any of the investigator or sponsor staff who are involved in the treatment or clinical evaluation of the subjects will be aware of the treatment received.
Intervention model description
Eligible subjects will be randomized to receive MEDI3506 or placebo as follows: Group 1: MEDI3506 Dose 1. Group 2: MEDI3506 Dose 2. Group 3: MEDI3506 Dose 3 Group 4: MEDI3506 Dose 4 Group 5: Placebo (volume matched) All subjects will receive Dapa from Day 85 to Day 168.

| Measure | Time frame | Description |
|---|---|---|
| Percent Change From Baseline to Day 169 (Week 24) in UACR - Per Protocol Population | From baseline to Day 169 | UACR values are collected as triplicates at baseline and at each CSP planned visit. For each triplicate, the UACR are averaged with geometric mean. Baseline is defined as the geometric mean of UACR measurements prior to first dose of study treatment. For the intercurrent events, if a subject is lost to follow-up (EOT), discontinues treatment due to AE, or uses prohibited medication, the UACR data are treated as missing on or after the event and no imputation is performed. The LS means of percent change and difference in percent change, corresponding 90% confidence intervals are calculated based on a mixed model with repeated measures (MMRM) of log (UACR post-baseline/UACR baseline) as the response, adjusting for fixed effects of treatment, visit, and treatment-by-visit interaction, SGLT2i, region (Japan or ROW), baseline log UACR, and baseline log UACR-by-visit interaction.

Proportion of Subjects With Reduction in UACR at Day 169 (Week 24) - Full Analysis Population
UACR values are collected as triplicates at baseline and at each CSP planned visit. For each triplicate, the UACR are averaged with geometric mean. Baseline is defined as the geometric mean of UACR measurements prior to first dose of study treatment. Only participants with values at Baseline and Day 169 are included.
Time frame: Baseline and Day 169
Population: Full Analysis Population:~All randomized participants who received any study drug.
