Spyre's investigational antibodies are engineered to improve on today’s standard of care – with the goal of getting more patients into deeper remission with therapies that can be delivered less frequently
We are committed to improving treatment options for patients with gastrointestinal and rheumatological diseases, aiming to help enhance their quality of life while managing their conditions effectively. Our focus is on developing innovative therapies that target specific aspects of these diseases:
Ulcerative colitis (UC) is a chronic inflammatory disorder characterized by inflammation in the colon and the rectum. Some symptoms may include bloody diarrhea, abdominal pain, bowel urgency, and frequent bowel movements. Approximately 1.3 million individuals in the U.S. have UC, with tens of thousands of new patients diagnosed annually. Despite recent advancements in treatment, a significant number of people living with UC continue to suffer from active disease. Today’s treatments are associated with many challenges, including low rates of remission and a high frequency of injections that may lead to poor compliance.
Crohn’s disease (CD) is a chronic inflammatory disorder characterized by inflammation in any part of the gastrointestinal tract, from the mouth to the rectum. Some symptoms may include abdominal pain, diarrhea, weight loss, fatigue, and complications such as strictures or fistulas. Approximately 1 million individuals in the U.S. have CD, with tens of thousands of new patients diagnosed annually. Despite recent advancements in treatment, a significant number of people living with CD continue to suffer from active disease. Today’s treatments are associated with many challenges, including low rates of remission and a high frequency of injections that may lead to poor compliance.
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune condition that primarily affects the joints. It is characterized by pain, stiffness and swelling of one or more joints and can progress from mild swelling of the joints in early stages to severe deformations of the feet, ankles, and hands in late/severe stages. RA is thought to arise from an aberrant immune response to modified proteins in mucosal tissue and the synovium, driven by genetic risk factors and environmental stressors. RA affects more than 1.5 million individuals in the U.S., with stable-to-increasing incidence of ~40 per 100,000 individuals. Despite several advanced treatment options, a significant number of people living with RA continue to suffer from active disease. Today’s treatments are associated with many challenges, including low rates of remission, loss of response, and a high frequency of injections that may lead to poor compliance.
Psoriatic arthritis (PsA) is a chronic inflammatory autoimmune condition that typically affects both the joints and skin. It is characterized by pain, stiffness, and swelling of one or more joints and can progress from mild swelling of the joints in early stages to severe deformations of the joints in late/severe stages. Other characteristics can include psoriasis (PsO; scaly patches on the skin and/or nail discoloration and pitting), dactylitis (swollen fingers and toes), and spondylitis (painful inflammation in the spine). PsA is thought to arise from genetic and environmental triggers, though the pathogenesis is multifactorial and not well understood. PsA affects approximately 0.8 million individuals in the U.S., with estimates suggesting that up to 15% of PsO patients may have undiagnosed PsA. Despite several advanced treatment options, a significant number of people living with PsA continue to suffer from active disease. Today’s treatments are associated with many challenges, including inability to adequately address both joint and skin symptoms, loss of response, and a high frequency of injections that may lead to poor compliance.
Axial spondyloarthritis (axSpA) is a chronic inflammatory autoimmune condition that primarily affects the axial skeleton (spine), with radiographic and non-radiographic subtypes. It is characterized by persistent back pain, stiffness, fatigue, joint stiffness, and frequent occurrence of extra-articular manifestations, such as anterior uveitis, IBD, and psoriasis. axSpA is thought to arise when biomechanical stress, genetics, environmental triggers, and other factors lead to overactivation of the immune system in the spine. axSpA affects an estimated 3 million individuals in the U.S., though only approximately 0.9 million of those are diagnosed. Despite some advanced treatment options, a significant number of people living with axSpA continue to suffer from active disease. Today’s treatments are associated with many challenges, including incomplete / loss of response, lack of MOAs to cycle through, and a high frequency of injections that may lead to poor compliance.
Product candidates discussed below are investigational and currently being studied in clinical trials. Their safety and efficacy have not been established and they have not been approved for any use by FDA, the European Commission, or any other health authority.
See our expanded access policyThis study will test the efficacy and safety of our long acting antibodies SPY001, SPY002, SPY003, and long acting combinations SPY120, SPY130, and SPY230 in adult patients with moderate-to-severely active ulcerative colitis. The study is anticipated to include a 12-week induction treatment period followed by a maintenance period.
This trial will test the efficacy and safety of SPY072 in adult patients with moderate-to-severe RA, PsA, and axSpA. The RA substudy is anticipated to include a 12-week placebo-controlled treatment period followed by an active treatment and safety follow-up periods. The axSpA andPsA sub-studies are anticipated to include a 16-week placebo-controlled treatment period followed by an active treatment and safety follow-up periods.
