Overview We are a biopharmaceutical company developing and commercializing novel therapeutics for the treatment of rare diseases of the immune system. We have successfully developed our first product, mavorixafor, in its first indication. Mavorixafor is an orally available, small-molecule selective antagonist of chemokine receptor CXCR4. Due to its ability to increase the mobilization of mature, functional white blood cells from the bone marrow into the bloodstream, we believe that mavorixafor has the potential to benefit people with a range of immunodeficiencies – a therapeutic market that is principally served by injectable therapies frequently associated with treatment-limiting adverse events.
Our Focus Since our inception, we have focused our business on the development of small-molecule, oral antagonists of the chemokine receptor CXCR4, or C-X-C receptor type 4. CXCR4 is a cell receptor that helps regulate the movement of immune cells within the body. CXCR4 receptor stimulation by its cognate ligand, CXCL12, has been shown to play a key role in the maturation and mobilization of white blood cells such as neutrophils, lymphocytes (including both B cells and T cells), and monocytes, into the bloodstream. Because antagonism of the CXCR4 receptor has been shown to increase the trafficking of white blood cells, we believe that therapeutic inhibition of the CXCR4/CXCL12 axis holds the potential to benefit people with a wide variety of diseases where there remain significant unmet needs, including chronic neutropenic disorders and certain types of cancer.

In April 2024, the U.S. Food and Drug Administration (“FDA”) approved mavorixafor, which is being marketed in the U.S. under the trade name XOLREMDI®, for use as an oral, once-daily therapy in patients 12 years of age and older with WHIM syndrome (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) to increase the number of circulating mature neutrophils and lymphocytes. XOLREMDI is the first drug approved in the U.S. to treat patients with WHIM syndrome. We launched XOLREMDI in May 2024 and are currently marketing the drug in the U.S. through our X4 commercial team.

We accelerate the impact of our portfolio by cultivating connections with patient communities, healthcare professionals, partners and colleagues to discover, develop and deliver potential therapies for rare diseases. Business Overview Rare diseases The lead product candidate in our portfolio, PYRUKYND® (mitapivat), is an activator of both wild-type and mutant pyruvate kinase, or PK, enzymes for the potential treatment of hemolytic anemias. PYRUKYND® is approved for use by the U.S. Food and Drug Administration, or FDA, for the treatment of hemolytic anemia in adults with PK deficiency in the United States and by the European Commission for the treatment of PK deficiency in adult patients in the European Union, or EU.
Revenues Our wholly owned product, PYRUKYND®, received approval from the FDA on February 17, 2022, for the treatment of hemolytic anemia in adults with PK deficiency in the United States. Upon FDA approval of PYRUKYND® in the United States, we began generating product revenue from sales of PYRUKYND®. We sell PYRUKYND® to a limited number of specialty distributors and specialty pharmacy providers, or collectively, the Customers. These Customers subsequently resell PYRUKYND® to pharmacies or dispense PYRUKYND® directly to patients. In addition to distribution agreements with Customers, we enter into arrangements with healthcare providers and payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks and discounts with respect to the purchase of PYRUKYND®.

We are currently conducting a pivotal Phase 3 clinical trial of mavorixafor in people with certain chronic neutropenic disorders (the 4WARD study). The Phase 3 trial is a global, randomized, double-blinded, placebo-controlled trial assessing the safety and efficacy of once-daily oral mavorixafor, with or without stable doses of G-CSF, in people with idiopathic or congenital, acquired primary autoimmune, or idiopathic chronic neutropenia who are experiencing recurrent and/or serious infections. The 52-week trial is expected to enroll 150 participants aged 12 years and older with both an ANC less than 1,500 cells per microliter and 2 or more infections requiring intervention during the 12 months preceding the trial.

Also in December 2024, we announced that we submitted a marketing authorization application, or MAA, to the European Medicines Agency, or EMA, and regulatory applications to the Kingdom of Saudi Arabia and United Arab Emirates health authorities for PYRUKYND® for the treatment of adult patients with non-transfusion dependent and transfusion-dependent alpha- or beta-thalassemia. In addition, we are currently evaluating PYRUKYND® in Phase 3 clinical trials for the treatment of sickle cell disease, or SCD, and in pediatric patients with PK deficiency. We are also developing (i) tebapivat, a novel PK activator, for the potential treatment of lower-risk myelodysplastic syndromes, or LR MDS, and hemolytic anemias; (ii) AG-181, our phenylalanine hydroxylase, or PAH, stabilizer for the potential treatment of phenylketonuria, or PKU; and (iii) AG-236, an siRNA in-licensed 3 Table of Contents
Reducing the level of 2,3-DPG in RBCs would increase the oxygenation state of hemoglobin to reduce sickling, while increasing the levels of ATP may improve RBC hydration status which may also inhibit the sickling process. Lower Risk MDS (LR MDS) MDS is a heterogeneous group of rare hematological malignancies characterized by dysfunctional hematopoiesis (or formation of blood cells), progressive cytopenia (or lower-than-normal number of blood cells) and an increased risk of progression to acute myeloid leukemia, or AML. The most common type of MDS is LR MDS, but many existing therapies and therapies under development focus on high risk MDS. Among patients with LR MDS, which accounts for approximately 70% of all MDS cases and are less likely to progress to AML, the primary concern is symptomatic anemia.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
