A 2-stage, Phase 2a Study to Evaluate the Efficacy, Safety, and Tolerability of OLP-1002 Subcutaneous Injections for Reducing Moderate to Severe Pain Due to Osteoarthritis in a Hip and/or Knee Joint
A 2-stage, Phase 2a Study to Evaluate the Efficacy, Safety, and Tolerability of OLP-1002 Subcutaneous Injections for Reducing Moderate to Severe Pain Due to Osteoarthritis in a Hip and/or Knee Joint
The study is designed to evaluate the efficacy, safety and tolerability of OLP-1002 Subcutaneous (SC) injections for reducing moderate to severe pain due to osteoarthritis in a hip and/or knee joint.
The study consists of two Stages (Stage 1 and Stage 2)
Stage 1: It is an open-label, dose-finding study employing a single ascending dose design to determine appropriate dose level starting dose of OLP-1002 for Stage 2 of the study in participants with moderate to severe pain due to osteoarthritis in a hip and/or knee joint.
Stage 1 consists of following:
Approximately 30 participants will be enrolled in Stage 1 of the study
Stage 2: The study will be a double-blind, placebo-controlled, parallel-arm study of up to 2 selected single doses of OLP-1002 to evaluate the efficacy of OLP-1002 in the treatment of pain in participants with moderate to severe pain due to osteoarthritis in a knee or hip joint.
Dose levels for Stage 2 will be 1 μg and 2 μg of OLP-1002. Dose selection was based on the conclusions drawn from the internal efficacy data review analysis conducted by Sponsor from data collected in Stage 1 of the study.
Stage 2 consists of following:
Approximately 90 participants will be enrolled in Stage 2 of the study

Pain in hip or knee joints, every day for at least 1-month during the 3 months prior to Screening.
Note: Participants must have a pain severity score of ≥ 5 based on the 3-day mean VAS score during the Baseline Period and must have recorded the pain score every day during the Baseline Period.

Women of childbearing potential (WOCBP) must be non-pregnant and non-lactating, and must use acceptable, highly effective double contraception from Screening until 90 days after the last dose of IP. Double contraception is defined as a condom AND one other form of the following:
Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not considered highly effective methods of birth control. A participant's treatment is acceptable.
Women not of childbearing potential must be postmenopausal for ≥ 12 months. Post-menopausal status will be confirmed through testing of FSH levels ≥ 40 IU/L at Screening for amenorrhoeic female participants. Female participants who are abstinent from heterosexual intercourse will also be eligible.
Female participants who are in a same-sex relationship are not required to use contraception.
Male participants must be surgically sterile (>30 days since vasectomy with no viable sperm), abstinent, or if engaged in sexual relations with a WOCBP, the participant and his partner must be surgically sterile (eg, tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or using an acceptable, highly effective contraceptive method from Screening until 90 days after the last dose of IP. Acceptable methods of contraception include the use of condoms and the use of an effective contraceptive for the female partner that includes: OCPs, long-acting implantable hormones, injectable hormones, a vaginal ring or an IUD.
Male participants with a same-sex partner (abstinence from penile-vaginal intercourse) are eligible when this is their preferred and usual lifestyle.
WOCBP must have a negative pregnancy test at Screening and Day 1 and be willing to have additional pregnancy tests as required throughout the study.
Male participants must agree not donate sperm for at least 90 days after the last dose of IP.
Agree to maintain their usual levels of activity throughout the course of the study.
Willing to abstain from other intra-articular treatments of the joint and any joint surgery while on the study.
Able to comply with study procedures, including the completion of daily questionnaires.
Subjects suffering from moderate to severe pain secondary to diagnosed OA of the knee and/or hip joint with fit for range of age & BMI will be included with proof of COVID 19 full vaccinations and intention of the participation in the study.
