Key Terms

subcutaneous formulations, monoclonal antibody, myeloproliferative neoplasms
3 terms
subcutaneous formulations medical
"to evaluate additional subcutaneous formulations of INCA033989"
Drugs formulated for subcutaneous use are medicines prepared to be injected just under the skin into the fatty tissue, rather than taken by mouth or given into a vein or muscle. Formulation choices (liquid, concentrated, or paired with an injector device) affect how easily patients can self-administer, how quickly the medicine is absorbed, and how products are manufactured and regulated—factors that influence market size, pricing, and commercial strategy.
monoclonal antibody medical
"a first-in-class mutant calreticulin (mutCALR)-targeted monoclonal antibody"
A monoclonal antibody is a laboratory-made protein designed to recognize and attach to a specific target in the body, such as a disease-causing substance or cell. It functions like a highly precise lock-and-key tool, helping to treat or detect illnesses. For investors, companies developing monoclonal antibodies can represent promising opportunities in the healthcare sector, especially as these treatments often address unmet medical needs.
myeloproliferative neoplasms medical
"patients with mutCALR-expressing myeloproliferative neoplasms (MPNs)"
Myeloproliferative neoplasms are a group of blood cancers caused by the bone marrow producing too many of one or more types of blood cells, which can crowd out normal cells and impair blood flow. Investors pay attention because these conditions create clear medical needs and predictable markets for diagnostics, therapies and follow-up care—similar to a failing factory that creates demand for repair services and replacement parts—affecting drug development, regulatory milestones and potential sales.

Agreement provides Incyte the rights to develop and commercialize ENHANZE® with its mutCALR development program and an option to nominate up to two additional targets

SAN DIEGO, July 20, 2026 /PRNewswire/ -- Halozyme Therapeutics, Inc. (Nasdaq: HALO) ("Halozyme" or the "Company") today announced that it has entered into a global collaboration and license agreement with Incyte (Nasdaq: INCY) to evaluate additional subcutaneous formulations of INCA033989, a first-in-class mutant calreticulin (mutCALR)-targeted monoclonal antibody, in patients with mutCALR-expressing myeloproliferative neoplasms (MPNs), utilizing Halozyme's proprietary ENHANZE® drug delivery technology. The collaboration will focus on the potential for ENHANZE® to strengthen the subcutaneous formulation currently in development for INCA033989, with the goal of enabling more convenient delivery and dosing regimens that may improve the treatment experience.

Under the terms of the agreement, Halozyme will receive an upfront payment from Incyte and is eligible to receive additional payments upon achievement of agreed upon milestones. In addition, Halozyme is eligible to receive royalties on net sales of commercialized medicines using ENHANZE®. Under the collaboration, Incyte also has the option to nominate up to two additional targets for use with ENHANZE®.

"This collaboration with Incyte underscores the continued momentum and broad applicability of our ENHANZE technology across high-value therapeutic areas," said Dr. Helen Torley, President and Chief Executive Officer of Halozyme. "Incyte brings a strong portfolio and deep expertise in hematology, and we look forward to working together to enable the development of more convenient subcutaneous treatment options for patients.
