- First patient enrolled in Phase 3 hip OA registration trial in late December 2018; trial expected to complete in 2020
- Positive results from Phase 2 pharmacokinetics (PK) study of ZILRETTA in OA of shoulder and hip showed PK profiles consistent with previous studies in knee
- Additional Phase 2 studies of shoulder OA and adhesive capsulitis (frozen shoulder) are planned for second half of 2019
BURLINGTON, MA, USA I January 02, 2019 I Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced that, on December 26, 2018, the first patient was enrolled in a Phase 3 clinical trial to evaluate the safety and efficacy of ZILRETTA (triamcinolone acetonide extended-release injectable suspension) in patients with hip osteoarthritis (OA). Similar to knee OA, hip OA is a degenerative disease which has no cure, and it is estimated that roughly 25% of the U.S. population may develop symptomatic hip OA in their lifetime.1
The initiation of the Phase 3 hip registration trial was supported by findings from a Phase 2, randomized, open-label, pharmacokinetic (PK) study in the shoulder and hip joints, known as the SHIP study. The results from the SHIP study demonstrated that ZILRETTA was generally safe and well tolerated, and the PK profile of ZILRETTA observed in both joints was consistent with previous PK studies in the knee. Results also showed that an injection of ZILRETTA into the hip resulted in 6-fold lower peak plasma levels and reduced systemic exposure compared to immediate-release triamcinolone acetonide in crystalline suspension (TAcs). The data on the hip cohort have been submitted for presentation.
“Like OA of the knee, OA of the hip is a serious disease that can profoundly affect one’s quality of life. These impacts are compounded by the fact that there are so few non-surgical treatment options available to manage OA hip pain, and we believe ZILRETTA may be able to play an important role in helping these patients find meaningful pain relief,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion. “We look forward to reporting the Phase 3 results with the expectation that the trial will read out in 2020.”
The double-blind, placebo-controlled Phase 3 trial will evaluate the efficacy and safety of ZILRETTA in 440 patients with hip OA pain. Patients will be randomized to one of two treatment groups (1:1) and treated with a single intra-articular (IA) injection of either ZILRETTA or normal saline (placebo). The primary endpoint of the trial is the magnitude of pain relief versus placebo as measured on the WOMAC A (pain) subscale at Week 12.2
Following initial injection of ZILRETTA or placebo, participants will be evaluated at Weeks 12, 16, 20 and 24 to determine if a second IA injection for hip OA pain is clinically indicated. If eligible for a second injection, patients will receive open label ZILRETTA at the time of recurrent symptoms and will be followed for 12 weeks after that injection. Patients who do not receive a second injection will be followed for up to 24 weeks after their first injection.
Flexion also plans to initiate additional Phase 2 studies of ZILRETTA in the shoulder later this year. The company intends to initially investigate ZILRETTA in both OA of the shoulder and adhesive capsulitis (frozen shoulder).
Indication and Select Important Safety Information for ZILRETTA
Indication: ZILRETTA is indicated as an intra-articular injection for the management of osteoarthritis pain of the knee. It is not intended for repeat administration.
Contraindication: ZILRETTA is contraindicated in patients who are hypersensitive to triamcinolone acetonide, corticosteroids or any components of the product.
Warnings and Precautions:
- Intra-articular Use Only: ZILRETTA has not been evaluated and should not be administered by epidural, intrathecal, intravenous, intraocular, intramuscular, intradermal, or subcutaneous routes. ZILRETTA should not be considered safe for epidural or intrathecal administration.
- Serious Neurologic Adverse Reactions with Epidural and Intrathecal Administration: Serious neurologic events have been reported following epidural or intrathecal corticosteroid administration. Corticosteroids are not approved for this use.
- Hypersensitivity reactions: Serious reactions have been reported with triamcinolone acetonide injection. Institute appropriate care if an anaphylactic reaction occurs.
- Joint infection and damage: A marked increase in joint pain, joint swelling, restricted motion, fever and malaise may suggest septic arthritis. If this occurs, conduct appropriate evaluation and if confirmed, institute appropriate antimicrobial treatment.
Adverse Reactions: The most commonly reported adverse reactions (incidence ≥1%) in clinical studies included sinusitis, cough, and contusions.

About ZILRETTA
On October 6, 2017, ZILRETTA was approved by the U.S. FDA as the first and only extended-release intra-articular therapy for patients confronting osteoarthritis-related knee pain. ZILRETTA employs proprietary microsphere technology combining triamcinolone acetonide — a commonly administered, short-acting corticosteroid — with a poly lactic-co-glycolic acid (PLGA) matrix to provide extended pain relief over 12 weeks
About Osteoarthritis (OA) of the Hip
OA, also known as degenerative joint disease, affects more than 30 million Americans and accounts for more than $185 billion in annual expenditures. It is estimated that roughly 25% of the population may develop symptomatic hip OA in their lifetime.1 Despite the prevalence of hip OA, there are very few non-surgical treatment options; however, the clinical practice guideline from American Academy of Orthopaedic Surgeons (AAOS) notes strong evidence supporting the use of corticosteroid injections to improve function and reduce pain in the short-term for patients with symptomatic hip OA.3
