Announcement
ANI Pharmaceuticals, Inc nnounced positive topline data from its Phase 4, open-label, single-arm SYNCHRONICITY clinical trial of Fluocinolone Acetonide Intravitreal Implant in patients with chronic non-infectious uveitis affecting the posterior segment of the eye (chronic NIU-PS)..
AI Summary
ANI Pharmaceuticals said its Phase 4 SYNCHRONICITY trial showed positive topline results for fluocinolone acetonide intravitreal implant in patients with chronic non-infectious uveitis affecting the back of the eye. The open-label, single-arm study supports the implant as a treatment option for patients with this recurring, vision-threatening condition.
Company leaders said the findings strengthen the case for use by retina specialists and add useful real-world data for everyday practice. A study investigator also said the results provide clinically meaningful information about how the therapy works in patients seen in retina clinics. ANI plans to present full details at upcoming medical conferences and continue discussions with the retina community.
Chronic NIU-PS can cause floaters, blurry vision, light sensitivity, reduced visual sharpness, and trouble seeing colors or in the dark.

Cortrophin Gel FDA Regulatory Timeline and Events
Cortrophin Gel is a drug developed by ANI Pharmaceuticals for the following indication: Injectable Gel.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- Cortrophin Gel
- Announced Date:
- June 12, 2025
- Indication:
- Injectable Gel
Announcement
ANI Pharmaceuticals, Inc. announced new preclinical data on the use of Purified Cortrophin Gel (repository corticotropin injection USP) (Cortrophin Gel) in a mouse model of murine collagen-induced inflammatory arthritis.
AI Summary
ANI Pharmaceuticals recently presented new preclinical data at the EULAR 2025 Congress. In a mouse model of collagen-induced inflammatory arthritis, the study examined the effects of Purified Cortrophin Gel, also known as repository corticotropin injection USP. The findings showed that the treatment reduced joint swelling and lowered the inflammatory cytokine response in a dose-dependent manner, with the 400 U/kg dose having the strongest effect. Importantly, the treatment did not lead to increased bone turnover or interfere with the formation of immunoglobulin G. Researchers led by Dr. Maripat Corr and Dr. Nancy Lane highlighted that these results expand the understanding of Cortrophin Gel’s mechanism of action. This study supports further exploration of Cortrophin Gel as a potential treatment for inflammation in arthritis, aiming to benefit patients by mitigating joint damage without additional adverse skeletal effects.

- Cortrophin Gel
- Announced Date:
- May 22, 2025
- Indication:
- Injectable Gel
Announcement
ANI Pharmaceuticals, Inc. announced the initiation of a Phase 4 clinical trial at Massachusetts General Hospital to compare the safety and efficacy of two dose levels (40 USP units and 80 USP units) of Purified Cortrophin Gel (repository corticotropin injection USP) (Cortrophin Gel) for the treatment of acute gout flares.
AI Summary
ANI Pharmaceuticals has started a Phase 4 clinical trial at Massachusetts General Hospital to study Purified Cortrophin Gel for treating acute gout flares. The trial, led by Dr. Hyon Choi, will compare two dose levels—40 USP units and 80 USP units—to evaluate their safety and effectiveness among patients who did not respond well to standard treatments.
The study is designed as a randomized, double-blind trial with a single injection followed by a 7-day follow-up period. Researchers will assess changes in pain intensity using a Visual Analog Scale and monitor the time to onset of effect and overall patient response. The goal is to generate significant scientific data to help doctors decide the best dosing strategy for managing acute gout flares, potentially offering improved pain relief and care options for patients suffering from this condition.

Announcement
ANI Pharmaceuticals, Inc. announced preclinical data on the use of Purified Cortrophin® Gel (repository corticotropin injection USP) (Cortrophin Gel) in an EAU mouse model.
AI Summary
ANI Pharmaceuticals recently shared promising preclinical data on the use of Purified Cortrophin® Gel in an experimental autoimmune uveitis (EAU) mouse model. In the study presented at the ARVO 2025 annual meeting, mice were given four different doses of the gel (4, 40, 160, and 400 U/kg). The results showed a clear, dose-dependent reduction in inflammation. The highest dose, 400 U/kg, provided the strongest suppression of EAU and significantly reduced levels of inflammatory molecules, while also protecting against retinal damage.
Dr. Mary Pao emphasized that the gel worked by lowering cytokine production without triggering any harmful immune responses. This study adds to the growing evidence of Cortrophin Gel’s potential therapeutic benefits, supporting further research into its use for inflammatory eye conditions like autoimmune uveitis.
