An Amniotic Membrane Injection Comparing Two Doses (1 mL and 2mL Injection) in the Treatment of Osteoarthritis of the Knee

Study Purpose

The purpose of this study is to determine the dose effect of a single injectable acellular amniotic membrane derived allograft injection for the treatment of knee osteoarthritis and to confirm whether the use of 2 mL of the same amniotic injection offers a statistically significant advantage over the 1 mL injection.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

It is a prospective, double blinded, Randomized Controlled Trial study. Data will be prospectively collected of all injectable acellular amniotic membrane derived allograft knee performed at our institute (1 vs.#46;2 mL). 60 subjects will be enrolled in this study. Subjects will be randomized 1:1 in treatment arms. Each of the patient will be treated with one time injection to the knee. Methods for collecting data will be through validated patient-reported outcome tools (KOOS, VAS and WOMAC questionnaire) that the patient will complete pre-injection and at specified time intervals after injection: 90 days, 180 days and 365 days.

Arms & Interventions


Active Comparator: 1 mL NyDYN injection

30 patients (out of 60) will be doubled blinded randomized to this arm and get 1 mL NyDYN injection.

Active Comparator: 2 mL NyDYN injection

30 patients (out of 60) will be doubled blinded randomized to this arm and get 2 mL NyDYN injection.


Drug: - Acellular amniotic membrane derived allograft injection (NuDYN)

Injectable acellular amniotic membrane derived allograft (NuDYN) through routine follow-up with physical examination, pain, function and quality of life measurements and compare dose effects (1 mL versus 2 mL of NuDYN injection) in the treatment of knee osteoarthritis.
