5 terms

fda-approved regulatory

"has now produced two FDA-approved, first-in-class medicines"

FDA-approved means a medical product, drug, device or treatment has passed the U.S. Food and Drug Administration’s review for safety and effectiveness for a specific use. Think of it like a formal safety and performance seal that allows the product to be marketed for that purpose in the U.S.; for investors, approval reduces regulatory uncertainty, enables sales and reimbursement pathways, and can materially affect a company’s revenue prospects and valuation.

interleukin-23 receptor medical

"precisely blocks the Interleukin-23 receptor"

A protein on the surface of certain immune cells that binds the signaling molecule interleukin-23 (IL-23) to trigger inflammatory responses. It acts like a lock that only the IL-23 key fits, turning on pathways that help defend against infection but can also drive chronic inflammation in conditions such as psoriasis and inflammatory bowel disease. Investors watch it because medicines that block this receptor can reduce disease activity, making it a common target in drug development and licensing deals.

phase 3 medical

"is in Phase 3 development for psoriatic arthritis"

Phase 3 is the late-stage clinical testing step for a new drug or medical treatment, where the product is given to large groups of patients to confirm effectiveness, monitor side effects, and compare it to standard care. Successful Phase 3 results are often the final scientific hurdle before regulators decide on approval and market launch—like passing a final exam before graduation—and can sharply change a company's valuation and future revenue prospects.

hepcidin mimetic peptide medical

"a first-in-class hepcidin mimetic peptide licensed to Takeda"

A hepcidin mimetic peptide is a short chain of amino acids engineered to act like hepcidin, the body’s natural hormone that controls iron levels by telling cells to hold on to iron and reducing iron release into the bloodstream. Investors care because these experimental drugs aim to treat iron-overload or chronic anemia conditions by changing how the body handles iron, and their progress through trials, approvals, and manufacturing can affect a biotech company’s value.

erythrocytosis medical

"approved in the U.S. for the treatment of erythrocytosis"

Erythrocytosis is an increase in the number or concentration of red blood cells in the bloodstream, which makes blood thicker—similar to syrup becoming more viscous than water. For investors, it matters because it can be a side effect or safety signal in drug development, a reason for regulatory scrutiny, or a factor that affects clinical trial outcomes and potential market approval, liability, or sales for healthcare companies.

About Protagonist

Protagonist Therapeutics is a biopharmaceutical company built on a proprietary peptide technology platform that has now produced two FDA-approved, first-in-class medicines, generating royalties and milestones from global commercial partnerships with Johnson and Johnson and Takeda Pharmaceutical Company Limited. ICOTYDE^™ (icotrokinra), licensed to Johnson & Johnson company Janssen Biotech, Inc., is the first and only targeted oral peptide that precisely blocks the Interleukin-23 receptor. ICOTYDE was launched in the U.S. in March 2026 for the treatment of moderate-to-severe plaque psoriasis in adults and pediatric patients 12 years of age or older and is in Phase 3 development for psoriatic arthritis, ulcerative colitis and Crohn's disease. ICOTYDE was jointly discovered by Protagonist and Johnson & Johnson scientists, with Protagonist having primary responsibility for the development of ICOTYDE through Phase 1, and Johnson & Johnson assuming responsibility for further clinical and regulatory development and commercialization. Protagonist also discovered and led research and development through Phase 3 for MIMRYLO^™ (rusfertide), a first-in-class hepcidin mimetic peptide licensed to Takeda Pharmaceutical Company Limited for worldwide commercialization. MIMRYLO is approved in the U.S. for the treatment of erythrocytosis in adults with PV. The Company also has a number of clinical and preclinical programs based on clinically and commercially validated targets and addressing unmet medical needs, including an oral IL-17 antagonist peptide, anti-obesity dual and triple agonists, an oral hepcidin functional mimetic, and the recently announced IL-4 and amylin discovery programs.
