 Index (WOMAC) pain and stiffness scores, as well as a meaningful improvement in Knee Injury and Osteoarthritis Outcomes Score (KOOS) functional assessment. In all 3 doses, over 70% of patients saw a 50% or greater improvement in pain compared to baseline at week 16 and 78. PCRX-201 was well-tolerated with no serious treatment-emergent adverse events related to the treatment or procedure reported regardless of steroid pretreatment or dose level administered. While other therapies typically provide relief for three to six months, PCRX-201 has shown the potential to set a new standard with pain relief lasting at least 2 years from a single injection.

Given these highly encouraging Phase 1 data, we are advancing a Phase 2 clinical study in knee OA. The two-part, multicenter study—known as ASCEND—will involve approximately 135 patients, 45 to 80 years old with painful OA of the knee at a Kellgren-Lawrence (K-L) Grade of 2, 3 or 4. Subjects are randomly assigned to a treatment dose group and stratified by K-L Grade, a semiquantitative method for evaluating the severity of OA on a scale of 0-4.

ASCEND will evaluate two doses of PCRX-201, Dose A is 1.4 x 1010 genome copies and Dose B is 1.4 x 1011 genome copies. Patients are being randomized 1:1:1 to Dose A, Dose B or saline. All cohorts will receive concurrent pretreatment with an IA corticosteroid (methylprednisolone 40 mg).

Part A of the study randomized approximately 45 patients and Part B will randomize approximately 90 patients. The drug product used in Part B of the study will be manufactured using our newly developed, suspension-based batch manufacturing process intended for commercial scale-up. We recently achieved our enrollment target for Part A of the study and expect to report results from a pre-specified interim analysis before the end of 2026.

For both Parts A and B of the study, the primary endpoint is the number and percent of treatment-emergent adverse events, adverse events of special interest, and serious adverse events for PCRX-201 plus steroid pretreatment versus saline plus steroid pretreatment from Week 1 through Week 52. The study’s secondary and exploratory endpoints include efficacy assessments such as changes in pain and physical function from baseline at Weeks
