Study Details

Study Description

Brief Summary

This study will evaluate safety, tolerability, pharmacokinetics and immunogenicity of MEDI7352 in healthy participants.

Condition or Disease	Intervention/Treatment	Phase
Painful Osteoarthritis of the Knee	Drug: MEDI7352 Drug: Placebo	Phase 1

Detailed Description

The study will comprise:

A Screening Period of up to 36 days (approximately 5 weeks);
A Treatment Period of 6 weeks where participants will be given 1 dose of study treatment every 2 weeks (4 doses in total). Participants will be required to stay in the Clinical Unit from Days -1 to 8 (Visit 2), from Days 14 to 15 (Visit 6), from Days 28 to 29 (Visit 9), and from Days 42 to 50 (Visit 12). In addition, participants will have multiple visits to the Clinical Unit to complete the study assessments;
A Follow-up Period of 42 days (6 weeks) where participants will also have multiple visits to the Clinical Unit to complete the study assessments, and;
A final Follow-up Visit after 42 days after the Treatment Period.

Participants will receive fixed multiple subcutaneous (SC) doses of MEDI7352 or placebo on 4 occasions; one dose every 2 weeks on Days 1, 15, 29 and 43, under fasted conditions.

Study Design

Study Type:

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Cohort 1: Japanese MEDI7352 Randomized Japanese participants will receive single doses of MEDI7352 subcutaneously.	Drug: MEDI7352 A dose of MEDI7352 will be administered as two 1.5 mL injections in the abdomen. Following an overnight fast of at least 8 hours, each participant will receive a single dose of MEDI7352 on 4 occasions.
Placebo Comparator: Cohort 1: Japanese Placebo Randomized Japanese participants will receive matching placebo subcutaneously.	Drug: Placebo Matching placebo will be administered as two 1.5 mL injections in the abdomen. To maintain the double-blind requirements, the placebo volume administered will be equivalent to the MEDI7352 volume administered for each dosing. Following an overnight fast of at least 8 hours, each participant will receive matching placebo on 4 occasions.
Experimental: Cohort 2: Caucasian MEDI7352 Randomized Caucasian participants will receive single doses of MEDI7352 subcutaneously.	Drug: MEDI7352 A dose of MEDI7352 will be administered as two 1.5 mL injections in the abdomen. Following an overnight fast of at least 8 hours, each participant will receive a single dose of MEDI7352 on 4 occasions.
Placebo Comparator: Cohort 2: Caucasian Placebo Randomized Caucasian participants will receive matching placebo subcutaneously.	Drug: Placebo Matching placebo will be administered as two 1.5 mL injections in the abdomen. To maintain the double-blind requirements, the placebo volume administered will be equivalent to the MEDI7352 volume administered for each dosing. Following an overnight fast of at least 8 hours, each participant will receive matching placebo on 4 occasions.
