Business Overview and History
Fulcrum Therapeutics, Inc. is a clinical-stage biopharmaceutical company at the forefront of developing small molecule therapies to improve the lives of patients with genetically defined rare diseases. With a steadfast focus on addressing unmet medical needs, Fulcrum has positioned itself as a trailblazer in the rare disease landscape, leveraging its proprietary discovery platform to systematically identify and validate cellular drug targets.
Fulcrum Therapeutics was founded in 2015 with the ambitious goal of tackling the root causes of genetically defined rare diseases. The company's initial focus was on organizing and staffing, business planning, raising capital, establishing intellectual property, building its discovery platform, identifying drug targets and potential product candidates, in-licensing assets, and conducting preclinical studies and clinical trials.
In 2019, Fulcrum achieved a significant milestone by going public on the Nasdaq exchange, raising $117 million from its initial public offering. This infusion of capital provided the company with additional resources to advance its pipeline of product candidates. At the time, Fulcrum's lead program was losmapimod, an oral small molecule for the treatment of facioscapulohumeral muscular dystrophy (FSHD).
The company further expanded its portfolio in 2020 by entering into a collaboration and license agreement with MyoKardia, a subsidiary of Bristol-Myers Squibb. This partnership focused on identifying and validating potential biological targets for the treatment of certain genetically defined cardiomyopathies, providing Fulcrum with upfront payments and the potential for future milestone and royalty payments.
Despite facing challenges, including the unsuccessful Phase 3 REACH trial for losmapimod in 2024, Fulcrum has maintained its commitment to rare, genetically defined diseases. The company's current lead program, pociredir, an oral HbF inducer for the treatment of sickle cell disease, has shown promising progress in clinical trials. Fulcrum's strong financial position, with $241 million in cash at the end of 2024, positions the company well to support its ongoing development efforts and explore new opportunities within the rare disease landscape.

Financial Performance and Liquidity
Fulcrum Therapeutics' financial results have reflected the company's steadfast focus on advancing its pipeline and expanding its rare disease initiatives. As a clinical-stage biopharmaceutical company, Fulcrum has not yet generated revenue from product sales, relying instead on strategic collaborations and partnerships to supplement its operational funding.
For the full year ended December 31, 2024, Fulcrum reported collaboration revenue of $80 million, a significant increase from the $2.8 million recorded in the previous year. This spike in revenue was primarily attributable to the $80 million upfront payment received from Sanofi as part of a collaboration and license agreement signed in 2024. The company's research and development expenses for the year totaled $63.4 million, down from $71.8 million in 2023, reflecting the strategic prioritization of its pipeline and the cost-sharing benefits of the Sanofi collaboration.
Fulcrum's strong financial position is further evidenced by its cash, cash equivalents, and marketable securities, which stood at $241 million as of December 31, 2024, up from $236.2 million at the end of 2023. This robust cash runway is expected to fund the company's operations into at least 2027, providing ample resources to advance its clinical programs and explore new opportunities within the rare disease landscape.
In the fourth quarter of 2024, Fulcrum reported no collaboration revenues, compared to $900,000 in the same period of 2023, due to the completion of research services under the MyoKardia collaboration agreement. Research and development expenses for Q4 2024 were $11.7 million, down from $19 million in Q4 2023, primarily due to decreased costs from the discontinuation of the losmapimod program and cost-sharing reimbursements from Sanofi, partially offset by increased costs for the PIONEER trial. The company reported a net loss of $16.6 million for Q4 2024, an improvement from the $24.8 million net loss in Q4 2023.
For the full year 2024, Fulcrum reported an annual revenue of $80 million, annual net income of -$9.7 million, annual operating cash flow of -$2.22 million, and annual free cash flow of -$2.5 million. The company's financial stability is further reflected in its debt-to-equity ratio of 0.035, current ratio of 22.63, and quick ratio of 22.63, indicating a strong liquidity position.
Pociredir: Advancing the Treatment of Sickle Cell Disease
Fulcrum's lead product candidate, pociredir, has emerged as a promising therapeutic option for individuals living with sickle cell disease (SCD). This first-in-class oral small molecule is designed to address the root cause of SCD by inducing the production of fetal hemoglobin (HbF), a crucial factor in mitigating the debilitating symptoms associated with the disease.
The company's ongoing Phase 1b "PIONEER" clinical trial of pociredir in SCD has made significant strides. In January 2023, Fulcrum announced interim data from the trial, which evaluated subjects both on and off background hydroxyurea therapy. Data from the 6 mg dose cohort showed up to 9.5 absolute increases in hemoglobin F (HbF) levels from baseline, with improved biomarkers of hemolysis observed in evaluable subjects.
Although the company completed enrollment in the 6 mg and 2 mg dose cohorts, it does not plan to enroll additional subjects in these cohorts. In February 2023, the FDA placed a full clinical hold on the investigational new drug (IND) application for pociredir for SCD. This hold was lifted in August 2023 after Fulcrum amended the protocol to revise the inclusion and exclusion criteria and target subjects with higher disease severity.
Since then, Fulcrum has reinitiated the Phase 1b trial at the 12 mg once daily dose level, with that cohort expected to enroll approximately 10 subjects. This will be followed by an additional cohort of around 10 subjects at the 20 mg once daily dose level. Subjects are evaluated over a 12-week treatment period.
The company is on track to report data from the 12 mg and 20 mg dose cohorts in mid-2025 and late 2025, respectively. These data readouts will provide valuable insights into the safety and efficacy of pociredir, potentially positioning the therapy as a transformative treatment option for SCD patients.
Notably, the data generated to date from the PIONEER trial have been highly encouraging. In the initial cohorts, pociredir demonstrated the ability to increase HbF levels by up to 10 percentage points from baseline, a finding that aligns with the growing body of evidence supporting the critical role of HbF in mitigating SCD symptoms. Furthermore, the therapy has been generally well-tolerated, with no serious adverse events reported thus far.
The potential of pociredir is further underscored by the withdrawal of OXBRYTA, a previously approved SCD therapy, from the global market. This development has heightened the urgency for new, safe, and effective treatment options that can address the significant unmet needs of the SCD community. Fulcrum's commitment to advancing pociredir positions the company at the forefront of this endeavor, with the potential to revolutionize the standard of care for individuals living with this debilitating condition.
Diversifying the Pipeline: Inherited Aplastic Anemias
Recognizing the importance of addressing a broader spectrum of rare diseases, Fulcrum has strategically expanded its pipeline beyond sickle cell disease. In 2023, the company entered into a license agreement with CAMP4 Therapeutics, gaining exclusive worldwide rights to develop therapeutic products for the treatment of Diamond-Blackfan anemia (DBA) and other inherited aplastic anemias.
This strategic move aligns with Fulcrum's mission to leverage its proprietary discovery platform to identify and validate cellular drug targets that can modulate gene expression and address the underlying causes of genetically defined rare diseases. The company plans to submit an Investigational New Drug (IND) application for a DBA program in the fourth quarter of 2025, further diversifying its rare disease pipeline and demonstrating its commitment to addressing unmet needs across multiple therapeutic areas.
Inherited aplastic anemias, such as DBA, Shwachman-Diamond syndrome, and Fanconi anemia, are a group of rare and often debilitating blood disorders characterized by the inability of the bone marrow to produce sufficient blood cells. These conditions can lead to a range of complications, including severe anemia, increased susceptibility to infections, and an elevated risk of developing certain types of cancer.
By expanding its focus to include these inherited aplastic anemias, Fulcrum is poised to leverage its expertise in modulating gene expression to potentially develop novel therapies that could transform the lives of patients afflicted by these rare and complex disorders. This diversification strategy not only strengthens the company's pipeline but also underscores its dedication to addressing the diverse needs of the rare disease community.
Navigating Challenges and Setbacks
Fulcrum's journey has not been without its fair share of challenges and setbacks. In September 2024, the company announced that its Phase 3 REACH trial evaluating losmapimod for the treatment of facioscapulohumeral muscular dystrophy (FSHD) did not meet its primary endpoint. Despite the disappointing results, Fulcrum remains committed to its core mission, refocusing its efforts and resources on advancing its pociredir program for sickle cell disease and the inherited aplastic anemia initiatives.
The suspension of the losmapimod program was a difficult decision, but it reflects Fulcrum's disciplined approach to resource allocation and its unwavering commitment to delivering meaningful results for patients. The company's ability to swiftly pivot and realign its priorities demonstrates its agility and strategic foresight, traits that will be crucial as it navigates the complexities of rare disease drug development.
Furthermore, Fulcrum has not been immune to the broader challenges facing the biopharmaceutical industry, such as the COVID-19 pandemic and its impact on clinical trial enrollment and operations. However, the company has demonstrated its resilience, adapting its processes and protocols to ensure the continued progress of its clinical programs, including the PIONEER trial for pociredir.
