Current report
Patient enrollment is affected by factors including:
Current report
Ongoing or unanticipated geopolitical events in countries where we may to have clinical trial sites could also negatively impact our ability to initiate, enroll and retain patients in, and conduct clinical trials.
Current report
For example, the USPI for PYRUKYND® includes a warning regarding the risk of potential hepatoceullar injury, and the USPI for AQVESME™ contains a boxed warning regarding the potential for hepatocellular injury. In addition, to mitigate the risk of hepatocellular injury, AQVESME™ is available only through the REMS program approved by the FDA. If we are unable to comply with any REMS imposed on any of our products, we may face additional restrictions, limitations or substantial penalties, any of which may materially adversely affect our business and results of operations. We cannot predict whether the FDA will request, seek to require or ultimately require modifications to, or impose additional requirements on, the AQVESME™ REMS.
Current report
Failure to comply with any of these laws and regulations could result in litigation, regulatory investigations or enforcement actions against us, orders to changes our practices, systems or policies, breaches of our contracts, fines, imprisonment of company officials and public censure, civil or criminal penalties, claims for damages by affected individuals, damage to our reputation and loss of goodwill, any of which could have a material adverse effect on our business, financial condition, results of operations or prospects. Even if we are not determined to have violated these laws, litigation or government investigations into these issues typically require the expenditure of significant resources and generate negative publicity.
Current report
In connection with our regulatory approvals in the EU, Great Britain and Saudi Arabia, we provide access to PYRUKYND® to eligible patients through the Avanzanite Agreement and the NewBridge Agreement, as applicable, and on either a free of charge or for charge basis for eligible patients in those jurisdictions and other jurisdictions through a global managed access program. We continue to evaluate other options for the commercialization of PYRUKYND® outside of the United States, including through exploring potential partnership opportunities.
Current report
In December 2025, as part of the National Defense Authorization Act for FY 2026, President Trump signed into law the BIOSECURE Act, which prohibits, subject to limited exceptions, the direct or indirect use of U.S. federal government contract, grant, and loan funds for purchasing biotechnology equipment and services from certain Chinese biotechnology companies of concern, or BCCs. Under the BIOSECURE Act, U.S. government agencies cannot (i) buy or obtain biotechnology equipment or services provided by a BCC, (ii) enter into, extend, or renew a contract with any entity using biotechnology equipment or services provided by a BCC to perform a government contract, or (iii) expend loan or grant funds for biotechnology equipment or services provided by a BCC. Instead of specifying particular Chinese entities as BCCs, the BIOSECURE Act treats any biotechnology companies that have been identified on the so-called 1260H List by the U.S. Department of Defense as Chinese Military Companies Operating in the United States as BCCs. The legislation allows for other biotechnology companies, possibly including WuXi entities, to be added to the federal funding prohibitions at a later time.
Current report
We use a third-party service provider to assist in the administration of the REMS for AQVESME™. If we or a third-party service provider acting on our behalf fail to effectively implement, monitor, report and administer the REMS for our products, we may be required to, among other things, modify such REMS, and we may be subject to FDA enforcement actions, such as seizure of the product, injunction against distribution, or to civil monetary penalties. If the FDA considers the conduct especially egregious, the FDA can refer the matter to the Department of Justice to pursue civil remedies, criminal prosecution or both. Additionally, if the third-party service provider fails to effectively administer the REMS, we could experience a material disruption to our commercial operations.
Current report
In addition, we do not have direct experience commercializing products outside of the United States and such efforts may depend on our ability to find a suitable distribution partner. For example, we have entered into the NewBridge Agreement and the Avanzanite Agreement for the commercialization of PYRUKYND® in certain jurisdictions outside of the United States. Pursuant to the NewBridge Agreement and the Avanzanite Agreement, we rely on our partners, in the GCC and in the EU and U.K., respectively, to assist with regulatory filings, prepare applications for pricing and reimbursement approval, negotiate with payors, conduct medical affairs activities and import, distribute, promote and commercialize our products in accordance with applicable law. If our distribution partners do not fulfill their obligations under these arrangements, or if they experience a change in strategic focus or available funding, our ability to generate revenue outside of the United States could be adversely affected.
Current report
In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted. For instance, in December 2025, the European Parliament and European Council reached a provisional political agreement on the revision of EU pharmaceutical legislation, which is expected to be adopted by mid-2026. If the legislation is finalized in line with the provisional political agreement, it will have a significant impact on the EU pharmaceutical industry, which could impact our business.
Current report
Disruptions at the FDA and other government agencies from funding cuts, personnel losses, regulatory reform, government shutdowns and other developments could hinder our ability to obtain guidance from the FDA regarding our clinical development program and develop and secure approval of our product candidates in a timely manner, which would negatively impact our business.
Current report
If oversight and review activities by the FDA and comparable foreign regulatory authorities are disrupted due to funding cuts, personnel losses, reductions in force, regulatory reform or government shutdown, then our ability to develop and/or secure timely approval of our product candidates could be impacted in a negative manner. For example, the recent loss of FDA leadership and personnel, including due to significant reduction in force, could lead to disruptions and delays in FDA guidance, review and approval of our product candidates.
Current report
Further, while the FDA’s review of marketing applications and other activities for new drugs and biologics is largely funded through the user fee program established under PDUFA, it remains unclear how the administration’s RIF and budget cuts will impact this program and the ability of the FDA to provide guidance and review our product candidates in a timely manner.
Current report
There is also substantial uncertainty as to how regulatory reform measures being implemented by the Trump administration across the government will impact the FDA and other federal agencies with jurisdiction over our activities. For example, President Trump has issued a number of executive orders that could have a significant impact on the manner in which the FDA conducts its operations and engages in regulatory and oversight activities. If these or other orders or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.
Current report
Accordingly, if any of the foregoing developments and others impact the ability of the FDA to provide us with guidance or delay the FDA’s review and processing of our regulatory submissions, our business would be negatively impacted.
Current report
Payments made to physicians in certain EU Member States must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual EU Member States. These requirements are provided in the national laws, industry codes or professional codes of conduct, applicable in the EU Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.
Current report
Since enactment of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively, the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace provisions of the law. President Trump recently revoked numerous executive orders issued by President Biden, including at least two executive orders which where were designed to further implement the ACA. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results.
Current report
On April 15, 2025, President Trump issued an executive order which directs HHS to take steps to reduce the prices of pharmaceutical products and repeats many of the proposals advanced during the first Trump administration, including directing the FDA to streamline and improve its existing drug importation program so as to make it easier for states to obtain approval without sacrificing the safety or quality of drug products. Other provisions of the executive order relate to the 340B program. With respect to the IRA’s Medicare drug pricing program, the executive order, among other things, calls for alignment in “the treatment of small molecule prescription drugs with that of biological products, ending the distortion that undermines relative investment in small molecule prescription drugs, coupled with other reforms to prevent any increase in overall costs to Medicare and its beneficiaries.” In May 2025, President Trump issued an additional executive order calling on pharmaceutical manufacturers to voluntarily reduce the prices of medicines in the United States. The executive order directs the Secretary of HHS to communicate MFN price targets to pharmaceutical manufacturers to bring prices in line with comparably developed nations. The executive order further provides that if such actions do not lower the costs of pharmaceuticals, the Secretary of HHS would pursue other actions, including proposing a rulemaking that imposes MFN pricing in the United States. Subsequently, HHS indicated that the proposed MFN pricing will apply only to brand products without generic or biosimilar competition and the referenced foreign countries will include only those in which the branded product similarly does not have generic or biosimilar competition. HHS also indicated that the MFN target price will be the lowest price in a country that is a member of the Organization for Economic Co-operation and Development with a gross domestic product per capita of at least 60% of the U.S. gross domestic product per capita. The implications of these actions remain unclear and our business could be negatively impacted.

Changes in and uncertainty surrounding U.S. trade policy could have a material adverse impact on our business, financial condition and results of operations.
Current report
The Trump administration recently initiated a series of tariff-related actions against U.S. trading partners. On April 2, 2025, the President issued an executive order announcing a “baseline” reciprocal tariff of 10% on all U.S. trading partners effective April 5, 2025, and higher individualized reciprocal tariffs on 57 countries (with certain product exemptions for pharmaceutical-related products, among others). Previously, the administration had imposed a 25% tariff on Canada and Mexico for goods not covered by the United States-Mexico-Canada Agreement, or USMCA, and tariffs equaling 20% on China. In response, several countries threatened retaliatory measures, including Canada and China, which then imposed retaliatory tariffs. Prior to when the country-specific reciprocal tariffs were scheduled to take effect, the administration delayed the effective date of such tariffs for all countries except China. Several countries, including the United Kingdom, Japan, South Korea, among others, and the European Union, have reached deals with the U.S. that include reduced tariff rates and other measures. President Trump also issued an executive order detailing new reciprocal tariff rates for individual countries that took effect on August 7, 2025. The new reciprocal rates, which are consistent with the rates reflected in the trade deals already announced, range from 10% to 41%. The new rates do not apply to Canada, China, Mexico and a few other countries.
Current report
The U.S. and China reached a tentative agreement that resulted in the suspension of the higher reciprocal tariffs on China until November 10, 2026. For China, the 10% baseline reciprocal tariff announced in April remains in effect, in addition to a minimum of an additional 10%, effective November 10, 2025. For Mexico, the rate remains 25% for goods that are not covered by the USMCA, and for Canada, the rate is 35% for goods that are not covered by the USMCA. Sustained uncertainty about, or the further escalation of, trade and political tensions between the United States and China could result in a disadvantageous research and manufacturing environment in China, particularly for U.S. based companies, including retaliatory restrictions that hinder or potentially inhibit our ability to rely on contract development and manufacturing organizations and other service providers that operate in China. Certain countries, including the European Union, Japan, South Korea and the United Kingdom, have reached agreements with the U.S. that cap pharmaceutical tariffs at 15%.
Current report
Separately, in April 2025, the U.S. Department of Commerce announced an investigation under Section 232 of the Trade Expansion Act of 1962 into the impact on U.S. national security of the imports of pharmaceuticals and pharmaceutical ingredients, including finished drug products, medical countermeasures, critical inputs such as active pharmaceutical ingredients, and key starting materials, and derivative products of those items. In September 2025, via a post on Truth Social, the President announced that, beginning October 1, 2025, all branded or patented drugs imported in the U.S. would face a 100% tariff. The President indicated that the tariffs could be avoided by building pharmaceutical manufacturing facilities in the U.S. Thereafter, the President delayed the October 1st effective date of the tariffs and announced that the administration had “begun preparing” tariffs on manufacturers that do not build in the U.S. or enter into a most-favored-nation drug pricing agreement with the administration. Certain trading partners, including the European Union, South Korea and Japan, negotiated exemptions from the Section 232 tariffs on pharmaceuticals. A host of other U.S. tariff actions remain possible, including an additional 25% tariff on products from countries that do business with Iran.
Current report
As a result of changes in tariffs that have been announced and/or implemented, and the underlying uncertainty currently surrounding international trade, we could experience a negative impact to our costs of materials and production processes, and supply chain disruptions and delays as a result of any new tariff policies or trade restrictions. If we are unable to obtain necessary raw materials or product components in sufficient quantity and in a timely manner due to disruptions in the global supply chain caused by macroeconomic events and conditions, the development, testing and clinical trials of our product candidates may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business. We cannot yet predict the effect of the recently imposed U.S. tariffs on imports, or the extent to which other countries will impose quotas, duties, tariffs, taxes or other similar restrictions upon imports or exports in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business.

PYRUKYND® (mitapivat) is approved for use by the 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 EU. Additionally, we received marketing authorization in Great Britain for PYRUKYND® for the treatment of PK deficiency in adult patients under the European Commission Decision Reliance Procedure. In December 2024, we announced that we submitted an sNDA, to the FDA for PYRUKYND® for the treatment of adult patients with non-transfusion dependent and transfusion-dependent alpha- or beta-thalassemia, which was accepted with standard review and granted a PDUFA goal date of September 7, 2025. Also in December 2024, we announced that we submitted a MAA to the 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.

Public health epidemics or pandemics may affect our ability to initiate or continue our planned, ongoing and future preclinical studies and clinical trials, disrupt regulatory activities, disrupt our ability to maintain a commercial infrastructure for our product or have other adverse effects on our business and operations.
Previous report
We may face delays, disruptions or shortages as a result of public health epidemics or pandemics that may affect our ability to initiate and complete preclinical studies and clinical trials or impact our commercialization efforts. We have previously experienced disruptions to certain clinical and research activities at our contract research organizations, or CROs, due to the COVID-19 pandemic. Any future pandemic or public health emergency could result in delays or pauses in site initiation, participant recruitment and enrollment, participant dosing, distribution of clinical trial materials, study monitoring and data analysis due to changes in hospital or university policies, federal, state or local regulations, diversion of hospital resources or other reasons related to a public health emergency. If a pandemic or public health emergency arises in the future, we may face difficulties recruiting or retaining patients in our ongoing clinical trials, and patients enrolled in our clinical trials may be unable or unwilling to visit clinical trial sites which may impact the collection of important clinical trial data and may necessitate remote data verification. In addition, limitations on the ability to visit sites may affect our enrollment timelines for our clinical trials, and may adversely affect the timing of completion of our clinical trials or our ability to complete clinical trials in a fully compliant manner. Additionally, the potential suspension of clinical trial activity at clinical trial sites or reduced availability of CRO personnel may have an adverse impact on our clinical trial plans and timelines.

Patient enrollment is also affected by other factors including:
Previous report
Under the federal Food and Drug Omnibus Reform Act, or FDORA, sponsors are required to develop and submit a diversity action plan for each phase 3 clinical trial or any other "pivotal study" of a new drug product. These plans are meant to encourage enrollment of more diverse patient populations in late-stage clinical trials of FDA-regulated products. In June 2024, as mandated by FDORA, the FDA issued draft guidance outlining the general requirements for diversity action plans. Unlike most guidance documents issued by the FDA, the diversity action plan guidance when finalized will have the force of law. . In January 2025, in response to an executive order issued by President Trump on Diversity, Equity and Inclusion programs, the FDA removed this draft guidance from its website. The implications of this action are not yet known. If we are not able to adhere to any new requirements, our ability to conduct clinical trials may be delayed or halted.
Previous report
In addition, we have a small number of clinical trial sites for certain clinical trials in the Middle East, including in Lebanon and Israel, that could be affected by the current armed conflict in the region.

For example, in January 2025, the USPI for PYRUKYND® for the treatment of hemolytic anemia in adults with PK deficiency was updated to include information regarding liver injury observed in patients with thalassemia treated with PYRUKYND® at a higher dose than recommended for patients with PK deficiency.
Previous report
If we are unable to properly protect the privacy and security of protected health information, we could be found to have breached our contracts. Further, if we fail to comply with applicable privacy laws, including applicable HIPAA privacy and security standards, we could face civil and criminal penalties. Enforcement activity by the U.S. Department of Health & Human Services, or HHS, can result in financial liability and reputational harm, and responses to such enforcement activity can consume significant internal resources. In addition, state attorneys general are authorized to bring civil actions seeking either injunctions or damages in response to violations that threaten the privacy of state residents. We cannot be sure how these regulations will be interpreted, enforced or applied to our operations. In addition to the risks associated with enforcement activities and potential contractual liabilities, our ongoing efforts to comply with evolving laws and regulations at the federal and state level may be costly and require ongoing modifications to our policies, procedures and systems.
Previous report
Plaintiffs’ lawyers in the United States are also increasingly using privacy-related statutes at both the state and federal level to bring lawsuits against companies for their data-related practices. In particular, there have been a significant number of cases filed against companies for their use of pixels and other web trackers. These cases often allege violations of the California Invasion of Privacy Act and other state laws regulating wiretapping, as well as the federal Video Privacy Protection Act. The rise in these types of lawsuits creates potential risk for our business.
Previous report
Beyond GDPR, there are privacy and data security laws in a growing number of countries around the world. While many loosely follow GDPR as a model, other laws contain different or conflicting provisions. These laws will impact our ability to conduct our business activities, including both our clinical trials and the sale and distribution of commercial products, through increased compliance costs, costs associated with contracting and potential enforcement actions.
Previous report
While we continue to address the implications of the recent changes to data privacy regulations, data privacy remains an evolving landscape at both the domestic and international level, with new regulations coming into effect and continued legal challenges, and our efforts to comply with the evolving data protection rules may be unsuccessful. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. We must devote significant resources to understanding and complying with this changing landscape. Failure to comply with laws regarding data protection would expose us to risk of enforcement actions taken by data protection authorities in the EEA and elsewhere and carries with it the potential for significant penalties if we are found to be non-compliant. Similarly, failure to comply with federal and state laws in the United States regarding privacy and security of personal information could expose us to penalties under such laws. Any such failure to comply with data protection and privacy laws could result in government-imposed fines or orders requiring that we change our practices, claims for damages or other liabilities, regulatory investigations and enforcement action, litigation and significant costs for remediation, any of which could adversely affect our business. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our business, financial condition, results of operations or prospects.

We are currently providing access to PYRUKYND® free of charge for eligible patients in the EU and Great Britain through a global managed access program, and we provide access to PYRUKYND® for adult patients with PK deficiency in other jurisdictions through the global managed access program on either a free of charge or for charge basis. Beyond the global managed access program, we continue to evaluate options for the commercialization of PYRUKYND® outside of the United States, including through exploring potential partnership opportunities, such as the NewBridge Agreement.

PYRUKYND® is the first product we have received marketing approval for following the sale of our oncology business. We have neither obtained marketing approval for PYRUKYND® in any other indications nor have we obtained marketing approval for any of our other product candidates, all of which are in preclinical or clinical development stages.

Previous report
Disruptions at the FDA and other agencies may prolong the time necessary for regulatory submissions to be reviewed and/or new drugs to be approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities. If a prolonged government shutdown were to occur, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. For example, should the FDA determine that an inspection is necessary for approval of a regulatory submission and an inspection cannot be completed during the review cycle, and the FDA does not determine a remote interactive evaluation to be adequate, the FDA has stated that it generally intends to issue a complete response letter or defer action on the regulatory submission until an inspection can be completed.
Previous report
In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted. For instance, EU pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical Strategy for Europe initiative. The European Commission’s proposal for revision of several legislative instruments related to medicinal products (including potentially reducing the duration of regulatory data protection and revising the eligibility for expedited pathways) was published in April 2023, and the European Parliament has requested several amendments in April 2024. The proposed revisions remain to be agreed and adopted by the European Parliament and European Council and the proposals may therefore be substantially revised before adoption, which is not anticipated before early 2026. The revisions may, however, have a significant impact on the pharmaceutical industry and our business in the long term.

If a product candidate is intended for the treatment of a serious or life-threatening disease or condition and the product candidate demonstrates the potential to address unmet medical needs for this disease or condition, the drug sponsor may apply for FDA fast track designation.
Previous report
Further, if the FDA determines that a product candidate offers major advances in treatment or provides a treatment where no adequate therapy exists, the FDA may designate the product candidate for priority review. A priority review designation means that the goal for the FDA to review an application is six months, rather than the standard review period of ten months. Receiving priority review from the FDA does not guarantee approval within the six-month review cycle or thereafter.
Previous report
Regulatory authorities in some jurisdictions, including the United States and the E.U., may designate drugs and biologics for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug or biologic intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States.

Indeed, under current legislation, the actual reductions in Medicare payments may vary up to 4%. The Consolidated Appropriations Act, which was signed into law by President Biden in December 2022, made several changes to sequestration of the Medicare program. Section 1001 of the Consolidated Appropriations Act delays the 4% Statutory Pay-As-You-Go Act of 2010 sequester for two years, through the end of calendar year 2024. Triggered by enactment of the American Rescue Plan Act of 2021, the 4% cut to the Medicare program would have taken effect in January 2023. The Consolidated Appropriations Act’s health care offset title includes Section 4163, which extends the 2% Budget Control Act of 2011 Medicare sequester for six months into fiscal year 2032 and lowers the payment reduction percentages in fiscal years 2030 and 2031.
Previous report
Since enactment of the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace provisions of the law. For example, in 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of health insurance, became effective in 2019. On November 10, 2020, the Supreme Court heard oral arguments as to whether the individual mandate portion of the ACA is an essential and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the ACA are invalid as well. On June 17, 2021, the Supreme Court struck down the lower court rulings, finding that the plaintiffs did not have standing to challenge the ACA’s minimum essential coverage provision at issue in the case.

To bring an action under the statute, an ANDA or 505(b)(2) sponsor must take certain steps to request the reference product, which, in the case of products covered by a REMS with elements to assure safe use, include obtaining authorization from the FDA for the acquisition of the reference product. If the sponsor does bring an action for failure to provide a reference product, there are certain affirmative defenses available to the NDA holder, which must be shown by a preponderance of evidence. If the sponsor prevails in litigation, it is entitled to a court order directing the NDA holder to provide, without delay, sufficient quantities of the applicable product on commercially reasonable, market-based terms, plus reasonable attorney fees and costs.

Previous wording
We have invested a significant portion of our efforts and financial resources in the identification of our product candidates and the development of our most advanced clinical programs, including PYRUKYND® and tebapivat. Our ability to generate meaningful product revenue will depend heavily on the successful clinical development and eventual commercialization of our current and any future product candidates, including PYRUKYND®. In December 2024, we announced that we submitted an sNDA to the FDA for PYRUKYND® for the treatment of adult patients with non-transfusion dependent and transfusion-dependent alpha- or beta-thalassemia, which was accepted with standard review and granted a PDUFA goal date of September 7, 2025. Also in December 2024, we announced that we submitted an MAA to the 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. We cannot be certain that we will obtain marketing approval of PYRUKYND® in thalassemia in such jurisdictions, nor can we be certain that we will obtain marketing approval of PYRUKYND® for any other indication or in other jurisdictions.

We have limited experience in the sale, marketing and distribution of pharmaceutical products. To achieve commercial success for approved medicines for which we retain sales and marketing responsibilities, we must either continue to develop our sales and marketing organization or outsource these functions to other third parties. We have established sales and marketing capabilities to support our commercialization of PYRUKYND® for the treatment of hemolytic anemia in adults with PK deficiency in the United States. In addition, in connection with our regulatory approvals in the EU and Great Britain, we are currently providing access to PYRUKYND® free of charge for eligible patients in those jurisdictions through a global managed access program. We provide access to PYRUKYND® for adult patients with PK deficiency in other jurisdictions upon request through the global managed access program, on either a free of charge or for charge basis. Beyond the global managed access program, we continue to evaluate options for the commercialization of PYRUKYND® outside of the United States, including through exploring potential partnership opportunities, including the NewBridge Agreement.

If we enter into arrangements with third parties to perform sales, marketing and distribution services, our product revenue or the profitability of product revenue to us are likely to be lower than if we were to market and sell any medicines that we develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell and market our product candidates or may be unable to do so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our medicines effectively. If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing PYRUKYND® or any of our product candidates for which we obtain marketing approval.

We have and may in the future enter into additional transactions to in-license products, technologies or assets or to acquire other products, technologies, assets or businesses. As part of the evolution of our research organization, we plan to prioritize in-licensing or acquiring assets for future pipeline growth. For example, in July 2023, we entered into a license agreement with Alnylam for the development and commercialization of products containing or comprised of an siRNA development candidate discovered by Alnylam and targeting the TMPRSS6 gene, and we have begun preclinical development of a product candidate for the potential treatment of patients with PV.
Current wording
We may engage in transactions to in-license products, technologies or assets or to acquire other products, technologies, assets or businesses. As part of our strategy, we plan to prioritize in-licensing or acquiring assets for future pipeline growth. For example, in July 2023, we entered into a license agreement with Alnylam for the development and commercialization of products containing or comprised of an siRNA development candidate discovered by Alnylam and targeting the TMPRSS6 gene, and we are developing a product candidate, AG-236, for the potential treatment of patients with PV.
Previous wording
Our ability to successfully in-license or acquire assets and develop product candidates following such transactions is unproven. If we do identify additional suitable candidates or assets for in-licensing transactions or acquisitions, we may not be able to make such transactions on favorable terms, or at all. Such transactions may require us to relinquish rights to develop product candidates in certain indications, limit our ability to pursue certain targets or require us to make significant milestone or royalty payments to third parties upon achievement of certain events. For example, we are responsible to pay up to $130.0 million in potential development and regulatory milestones, in addition to sales milestones as well as tiered royalties on annual net sales, if any, of any licensed products, under the license agreement with Alnylam. Further, any in-licensing transaction or acquisitions we undertake may not strengthen our competitive position, and these transactions may be viewed negatively by customers or investors. We may decide to incur debt in connection with an acquisition or an in-licensing transaction or issue our common stock or other equity securities to the stockholders of the counterparty, which would reduce the percentage ownership of our existing stockholders. We could incur losses resulting from undiscovered liabilities of the acquired business, product or technology that are not covered by the indemnification we may obtain from the seller. In addition, we may not be able to successfully integrate the acquired personnel, technologies and operations into our existing business in an effective, timely and non-disruptive manner. Such transactions may also divert management attention from day-to-day responsibilities, increase our expenses and reduce our cash available for operations and other uses. We cannot ensure that following any transaction we would achieve the expected synergies to justify the transactions. We cannot predict the number, timing or size of future transactions or the effect that any such transactions might have on our operating results.

The outcome of preclinical studies and early clinical trials may not be predictive of the success of later clinical trials, and positive results of completed clinical trials do not necessarily predict success in future clinical trials. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in earlier stages of development, and we could face similar setbacks. The design of a clinical trial can determine whether its results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. In addition, preclinical and clinical data are often susceptible to varying interpretations and analyses. Many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval for the product candidates. Even if we or our collaborators believe that the results of clinical trials for our product candidates warrant marketing approval, the FDA or comparable foreign regulatory authorities may disagree and may not grant marketing approval of our product candidates.

In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants. The results of clinical trials of PYRUKYND® for the treatment of PK deficiency and thalassemia are not predictive of results of our ongoing clinical trials of PYRUKYND® in other indications, such as SCD, and the results of our early-stage clinical trials of tebapivat are not predictive of our later stage clinical trial of tebapivat. If we fail to receive positive results in clinical trials of our product candidates, the development timeline and regulatory approval and commercialization prospects for our most advanced product candidates, and, correspondingly, our business and financial prospects would be negatively impacted.

Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time-consuming, and may result in current or future product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction.

Because we have limited financial and managerial resources, we focus on research programs and product candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. We are prioritizing investment in advancing our late lead-optimization research, while continuing to progress our registration-enabling clinical programs in thalassemia, SCD and pediatric PK deficiency, our phase 2 trial in LR MDS, our phase 1 trial for AG-181, our PAH stabilizer for the potential treatment of PKU, and AG-236, our preclinical development of a product candidate for the potential treatment of patients with PV. Our resource allocation decisions may cause us to fail to capitalize on viable commercial medicines or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable medicines. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.
