Business Overview and History
Agios Pharmaceuticals, Inc. (AGIO) is a biopharmaceutical company at the forefront of cellular metabolism and rare disease research. With a deep expertise in pyruvate kinase (PK) activation, Agios is pioneering life-changing therapies for patients living with debilitating rare diseases. The company's strategic vision, robust pipeline, and strong financial position position it for transformative growth in the years ahead.
Agios Pharmaceuticals, Inc. was founded in 2007 and is headquartered in Cambridge, Massachusetts. The company is focused on developing therapies for rare diseases, with a particular emphasis on rare blood disorders and diseases related to cellular metabolism.
In March 2021, Agios completed the sale of its oncology business, including the commercial product TIBSOVO and several clinical-stage oncology assets, to Servier Pharmaceuticals. This transaction allowed Agios to focus its resources on its rare disease pipeline, anchored by its lead product candidate PYRUKYND (mitapivat).
PYRUKYND is an activator of both wild-type and mutant pyruvate kinase (PK) enzymes and was developed for the treatment of PK deficiency, a rare genetic disorder that leads to a shortened lifespan of red blood cells. In February 2022, PYRUKYND received FDA approval for the treatment of hemolytic anemia in adults with PK deficiency in the United States. This represented a significant milestone for Agios as it transitioned from a development-stage company to a commercial-stage rare disease company.
Prior to the sale of its oncology business, Agios had financed its operations primarily through collaborations, private placements, public offerings, and the sale of royalty rights. Following the oncology divestiture, the company has focused on financing its operations through cash on hand, potential royalty payments, and the commercialization of PYRUKYND. Agios has also continued to advance its pipeline of rare disease programs, including tebapivat for the potential treatment of lower-risk myelodysplastic syndromes and AG-181 for the potential treatment of phenylketonuria.
Throughout its history, Agios has faced the typical challenges associated with developing and commercializing novel therapies for rare diseases, including navigating the regulatory approval process, establishing manufacturing and supply chains, and building commercial capabilities. However, the company's focus on cellular metabolism and rare hematological disorders has allowed it to develop a unique expertise in these areas, positioning it to continue advancing its pipeline and delivering transformative therapies to patients.
In 2022, Agios received its first FDA approval for PYRUKYND® (mitapivat), a first-in-class PK activator, for the treatment of hemolytic anemia in adults with PK deficiency, a rare genetic disorder. This landmark achievement marked Agios' transition from a clinical-stage biotechnology company to a commercial-stage rare disease leader.
Beyond PK deficiency, Agios has rapidly advanced PYRUKYND into late-stage development for thalassemia and sickle cell disease, two other devastating hemolytic anemias with high unmet need. In December 2024, the company announced the simultaneous submission of regulatory applications for PYRUKYND in thalassemia in the U.S., EU, Saudi Arabia, and UAE. With a PDUFA date set for September 2025, PYRUKYND could become the first approved oral therapy for both non-transfusion dependent and transfusion dependent thalassemia patients.
In addition to its lead program, Agios has built a robust pipeline of novel PK activators and other first-in-class therapies targeting rare diseases. This includes tebapivat, a next-generation PK activator in phase 2 development for lower-risk myelodysplastic syndromes (MDS) and sickle cell disease, as well as AG-181, a phenylalanine hydroxylase (PAH) stabilizer for phenylketonuria (PKU).
Financials and Liquidity
Agios reported net product revenue of $36.5 million in 2024, a 36% increase year-over-year, driven by the continued uptake of PYRUKYND in PK deficiency. Gross margins remained strong at 88.6% in 2024. The company's Q4 2024 revenue was $10.7 million, representing a 51% increase compared to Q4 2023, primarily due to increased volume associated with PYRUKYND. However, Q4 2024 revenue was higher due to year-end stocking and revenue reserve adjustments of approximately $1.6 million, which are not expected to repeat in Q1 2025.
The company ended 2024 with a robust cash, cash equivalents, and marketable securities balance of $1.5 billion. This provides Agios with the financial independence to maximize the potential of PYRUKYND's upcoming commercial launches, advance its mid- and early-stage pipeline programs, and strategically expand its rare disease portfolio through business development.
In 2024, Agios received two significant milestone payments totaling $1.1 billion. This included $905 million from the sale of the vorasidenib royalty rights to Royalty Pharma, as well as a $200 million payment from Servier related to the 2021 divestiture of Agios' oncology business. Going forward, Agios will retain a 3% royalty on annual U.S. net sales of vorasidenib above $1 billion.
Agios reported a net income of $673.7 million for the fiscal year 2024, primarily driven by the $889.1 million gain on the sale of the Vorasidenib Royalty Rights and the $200 million Vorasidenib Milestone Payment received in 2024. This was a significant improvement compared to the net loss of $352.1 million in 2023. However, the company's Q4 2024 net loss was $96.5 million.
The company's annual operating cash flow for 2024 was -$389.8 million, with annual free cash flow at -$391.5 million. Agios maintains a strong liquidity position with a debt-to-equity ratio of 0.037, a current ratio of 11.90, and a quick ratio of 11.56. As of December 31, 2024, the company had $76.3 million in cash and cash equivalents and $1.46 billion in marketable securities.
Product Portfolio and Pipeline
Agios' product portfolio and development pipeline are centered around two main segments: PK Activator Programs and Other Programs.
PK Activator Programs: PYRUKYND (mitapivat) is Agios' lead product and is approved for the treatment of hemolytic anemia in adults with PK deficiency in the United States and the European Union. In December 2024, Agios submitted regulatory applications for PYRUKYND in thalassemia in the U.S., EU, Saudi Arabia, and UAE. The FDA accepted the supplemental new drug application (sNDA) with a PDUFA goal date of September 7, 2025.
PYRUKYND is also being evaluated in Phase 3 clinical trials for the treatment of sickle cell disease (SCD) and in pediatric patients with PK deficiency. Agios has built a commercial infrastructure to support the commercialization of PYRUKYND in adult PK deficiency in the United States and is expanding this infrastructure to support the potential launch of PYRUKYND in thalassemia.
In addition to PYRUKYND, Agios is developing tebapivat, a novel PK activator, for the potential treatment of lower-risk myelodysplastic syndromes (LR MDS) and hemolytic anemias. Tebapivat has been granted orphan drug designation for the treatment of MDS by the FDA.
Other Programs:
Agios' other development programs include AG-181.00, a phenylalanine hydroxylase (PAH) stabilizer for the potential treatment of phenylketonuria (PKU), and AG-236.00, an siRNA licensed from Alnylam Pharmaceuticals targeting the TMPRSS6 gene for the potential treatment of polycythemia vera (PV).
In July 2023, Agios entered into a license agreement with Alnylam to acquire the rights to develop and commercialize Alnylam's novel preclinical siRNA candidate targeting TMPRSS6 for PV. As part of the agreement, Agios made an upfront payment of $17.5 million to Alnylam and is responsible for paying up to $130 million in potential development and regulatory milestones, as well as sales milestones and tiered royalties on annual net sales of the licensed products.
Outlook and Catalysts
2025 is poised to be a transformative year for Agios, with several key milestones on the horizon:
1. Thalassemia Regulatory Approvals: Agios' supplemental new drug application (sNDA) for PYRUKYND in thalassemia was accepted by the FDA in January 2025, with a PDUFA goal date of September 7, 2025. Approvals in the EU, Saudi Arabia, and UAE are also expected. If approved, PYRUKYND would become the first oral therapy indicated for both non-transfusion dependent and transfusion dependent thalassemia patients.
2. Sickle Cell Disease Phase 3 Readout: Agios completed enrollment in the Phase 3 RISE UP study evaluating PYRUKYND in sickle cell disease in 2024. Topline results are expected in late 2025, with a potential U.S. commercial launch in 2026 if positive.
3. Pipeline Advancement: Agios plans to initiate a Phase 2 study of its novel PK activator tebapivat in sickle cell disease in mid-2025. The company also expects to file an IND for AG-236, an siRNA targeting TMPRSS6 for polycythemia vera, in mid-2025.
For 2025, Agios expects PYRUKYND revenues for PK deficiency to be relatively flat compared to 2024. The company anticipates a partial quarter of revenue in Q4 2025 for the potential launch of PYRUKYND in thalassemia, considering the time needed to set up payer access and for patients to initiate therapy after prescription enrollment. Agios is confident in the team's ability to translate the favorable market dynamics in thalassemia into a significant revenue trajectory for the product beyond 2025.
Risks and Challenges
While Agios' growth prospects are compelling, the company faces several key risks and challenges:
1. Commercial Execution: The successful commercialization of PYRUKYND in thalassemia and sickle cell disease will be critical to Agios' long-term success. Effective disease state education, payer engagement, and right-sizing of the commercial organization will be essential.
2. Clinical Development Risks: Agios' pipeline advancement hinges on positive results from ongoing and future clinical trials. Any delays or setbacks in the development of PYRUKYND, tebapivat, or other programs could significantly impact the company's timeline and growth trajectory.
3. Competitive Landscape: Agios faces competition from other therapies, both approved and in development, for the treatment of hemolytic anemias and other rare diseases. Maintaining PYRUKYND's competitive edge will require continuous innovation and differentiation.
4. Regulatory Uncertainties: While the acceptance of Agios' regulatory submissions for PYRUKYND in thalassemia is a positive sign, there is no guarantee of approval. Unfavorable regulatory decisions or label restrictions could negatively impact the product's commercial potential.
