Drug Repurposing Market Summary

The global drug repurposing market size was estimated at USD 32.96 billion in 2024 and is projected to reach USD 47.40 billion by 2033, growing at a CAGR of 4.12% from 2025 to 2033. The market has gained significant traction, driven by the potential to offer both cost-effective and time-efficient solutions for pharmaceutical companies.

A critical driver of this growth is the opportunity to leverage existing drugs with well-established safety profiles, significantly reducing the need for lengthy preclinical trials and early-phase clinical development. For instance, in September 2023, the FDA approved empagliflozin (brand name Jardiance), a medication originally developed for type 2 diabetes, for the treatment of chronic kidney disease (CKD) in adults at risk of progression, regardless of diabetes status.

Empagliflozin, developed by Boehringer Ingelheim and Eli Lilly, has shown promising results in clinical trials for reducing the risk of kidney function decline, kidney failure, cardiovascular death, and hospitalization for heart failure in CKD patients. While initially approved for type 2 diabetes, this approval extends its potential beyond diabetes management, demonstrating the growing trend of repurposing existing drugs for conditions with limited treatment options. This move highlights the increasing support for drug repurposing efforts and the significant benefits of leveraging established medications for new therapeutic indications.

Furthermore, the rising prevalence of chronic and rare diseases has significantly contributed to the push for repurposed drugs. For example, in December 2022, the FDA approved cariprazine (brand name Vraylar) as an adjunctive treatment for major depressive disorder (MDD) in adults who have had an inadequate response to antidepressant therapy. Cariprazine was originally developed by Gedeon Richter and was first approved by the FDA in 2015 for the treatment of schizophrenia and bipolar I disorder. AbbVie acquired the rights to cariprazine through its acquisition of Allergan in 2020. This approval marks the fourth indication for Vraylar, underscoring the growing trend of repurposing existing medications to address conditions with limited treatment options.

In March 2023, the FDA approved leniolisib (brand name Joenja), a medication originally developed for activated phosphoinositide 3-kinase delta syndrome (APDS), for the treatment of activated PI3K delta syndrome, a rare immune disorder. Leniolisib is a selective inhibitor of the PI3Kδ enzyme, which plays a crucial role in immune cell function. The approval of leniolisib highlights the growing trend of repurposing existing drugs to address rare and orphan diseases, where the development of new drugs can be cost-prohibitive and time-consuming. This strategic move underscores the increasing support for drug repurposing efforts to encourage the development of treatments for conditions with limited therapeutic options.

In drug repurposing, Pfizer has been actively engaged in advancing treatments for prostate cancer. In July 2021, Pfizer entered into a global collaboration with Arvinas to co-develop and co-commercialize ARV-471, an investigational oral PROTAC® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. This partnership aims to leverage existing treatments to address complex and underserved cancers, aligning with Pfizer's broader strategy to expand its oncology portfolio. Additionally, in April 2024, Arvinas entered into a separate licensing and asset-sale agreement with Novartis, valued at over USD 1 billion, for the development and commercialization of ARV-766, a second-generation androgen receptor degrader for prostate cancer. This move underscores the growing interest and investment in repurposing existing drugs to enhance treatment options for prostate cancer patients.

In January 2025, Bayer submitted an sNDA to the U.S. Food and Drug Administration (FDA) seeking approval for Kerendia to treat adult patients with heart failure (HF) and a left ventricular ejection fraction (LVEF) of ≥40%, including both mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF). The FDA accepted the application and granted Priority Review designation. The FDA approved this new indication on July 14, 2025, following the agency’s Priority Review of its supplemental New Drug Application (sNDA
