Primary Objective:~A Phase 1, open-label, non-controlled trial, to assess the safety of intra-articular injection of SIG001, at either of two doses, in a total of 10 patients with Symptomatic Osteoarthritis of the Knee, Kellgren-Lawrence Grade 2-3, at 7, 30, 90 and 180 days after dosing.~Secondary Objective:~A Phase 1, open-label, non-controlled trial, to obtain very early data relating to any effects of intra-articular injection of SIG001, at either of two doses pain, activity, and quality of life in 10 patients with Symptomatic Osteoarthritis of the Knee, Kellgren-Lawrence Grade 2-3, at 7, 30, 90 and 180 days.~Study Design:~The Phase 1 trial will enroll 5 subjects into an initial group receiving a low dose of SIG001. Provided that these subjects tolerate this dose well, will proceed to enroll 5 subjects into a group receiving a high dose of SIG001.
This study is a Phase 1 trial. The overall objective is to evaluate the safety and potential efficacy of a specific type of umbilical cord tissue-derived product (SIG001), which, other than a change in cryopreservation medium to render it compatible with cGMP, is similar to the reported real-world experience from 2 clinics on 135 knees.
