Dear Friends,
This year marks the 30 anniversary of the Alpha-1 Foundation (A1F), a significant milestone and an opportunity to reflect on where we have come from, what we have accomplished, and the work that remains to be done. The purpose of this Impact Report is to carry out those tasks and to attempt to measure how effective we have been in accomplishing our goals. Since the last report five years ago, we have made significant progress as a community. We have navigated a pandemic, resumed in-person activities, and overseen a resurgence of research interest in Alpha-1 Antitrypsin Deficiency (AATD).
We can now cheer for multiple new therapeutic modalities being tested in clinical trials, an enviable and unique situation among genetic diseases and a welcome departure from prior years when there were few new treatment options on the horizon. We feel great urgency to make the most of this opportunity, and it is with that urgency in mind that we now take the measure of our prior accomplishments and look ahead.
This report documents the output of a robust and outstanding community of researchers, physicians, A1F staff, and patients working together towards a common goal. I hope you will share in the optimism that I feel when reviewing our progress and the position we now occupy as we look ahead. As always, we are guided and inspired by lessons learned from John and Fred Walsh, who taught us to be impatient in our expectations for progress and to remember to “Keep the Faith.”
Sincerely,

Andrew Wilson, MD A1F Scientific Director
Promoting research with the vision of finding better treatments and ultimately a cure for AATD has been a major focus of A1F for the past 25 years. Investigatorinitiated grants have been the driving force of A1F’s research program from its inception in 1999, based on the time-tested principle in biomedical discovery that innovative ideas typically arise in the research community. Between 1999 and 2024, over $100 million has been invested in research. Of those funds, approximately 50% was directed at the peer-reviewed investigator-initiated grants program while the remainder was used to organize and publish the proceedings of scientific conferences, and to support the DNA & Tissue Bank and the Alpha-1 Research Registry along with other programs as resources for basic and clinical researchers.
A1F-sponsored research has had a significant impact on our understanding of the mechanisms leading to the clinical manifestations of AATD, and most of this information has been obtained through investigations supported by investigator-initiated grants (Figure 1).
Figure 1 Alpha-1 Foundation investigator-initiated grant program
The program is based on the concept that investigator-initiated research leads to scientific publications and is the basis of scientific meetings, which facilitate cross-pollination, amplifying the impact of new findings and informing the biotech and pharmaceutical companies in their quest for new therapeutic solutions. A1F support has the additional benefit of attracting and retaining the scientific workforce to focus on AATD. This document aims to summarize the scientific contributions of this research from 1999 to 2024.
A1F has issued 85 new grant awards to individual investigators totaling $14.1 million between 2019-2024 since the last impact report.
Applications for A1F funding are increasing. During the COVID-19 pandemic, applications for funding declined as research became more challenging to conduct and the time of physician-researchers was occupied with patient care. Applications for funding were at their lowest in 2020 and remained low for several years but have subsequently rebounded, as indicated in Figure 2. For the 2024-2025 cycle, we received the highest number of letters of intent (LOIs) to submit a grant proposal in the past 10 years.
Applicants come from a variety of institutions and countries: Cutting-edge research that advances the field can happen in many locations around the world. To leverage worldwide expertise in the service of AATD patients, A1F receives and funds research proposals from many different countries, representing many institutions.
The home countries of A1F-funded investigators as well as the number of institutions they represent are listed in the charts below:
3: Location of A1F-Funded Investigators
4: Number of Institutions Receiving A1F Funding
Cultivating New Investigators: In addition to generating new knowledge that can benefit AATD patients, A1F support encourages researchers to study AATD, bringing new researchers into the field who in some cases go on to study AATD for long periods of time. Each year, A1F grants are awarded to PIs who have never previously applied for funding, demonstrating how the program functions to recruit new investigators.
Funding levels: The total amount of funds awarded by A1F to support research can vary from year to year based on several factors, including the number of meritorious applications received and availability of funds to commit for this purpose. Following the decline in applications and associated funds awarded from 2020-2022, A1F has increased total funds awarded in support of research grants in the past two fiscal years.

A1F has developed a rigorous process, modeled on the The National Institutes of Health (NIH), to vet grant applications and ensure that our funds support the highest quality research. It is important that we measure the impact of A1F support to validate the efficacy of this approach. We can measure this impact in a variety of ways, including the metrics below:
NIH grant support resulting from A1F funding: NIH is historically the largest funder of biomedical research in the world. We encourage A1F-funded researchers to build on the findings they make with A1F support to apply for additional funding from the NIH. A1F investment of $48.9 million in investigator-initiated proposals from 1999-2025 has subsequently resulted in $732.8 million in funds from the federal government to our awardees, a return-on-investment of approximately $15 per dollar awarded.
Publications resulting from A1F funding: Dissemination of research findings is critical to advance scientific knowledge. A1F-funded investigators are strongly encouraged to publish findings they make with A1F support. From 2018-2025, A1F-funded investigators published 153 articles in scientific journals on all aspects of AATD.
Patents resulting from A1F funding: Research findings have the potential to identify mechanisms or develop techniques with potential therapeutic value. Patent activity is thus an additional measure of impact. Between 2001-2025, A1F funded investigators have filed 48 patent applications.
A key aspect of our mission is to develop new treatments and ultimately a cure for patients with AATD. In the 5 years since the last impact report, the AAT therapeutic landscape has changed dramatically, with numerous drugs targeting a variety of mechanisms advancing to preclinical development or clinical trials. This evolution reflects a combination of increased understanding of cellular disease mechanisms together with technological advances, particularly in the ability to manipulate gene architecture and expression through a variety of approaches. Our community is fortunate that seminal advances in genetic targeting (collectively including Nobel prize-winning discoveries such as RNA interference and CRISPR, together with gene therapy and RNA editing) that can be applied to many genetic diseases are potentially therapeutically useful in AATD. The development of small molecules to assist in proper folding or stabilize misfolded AAT proteins has likewise shown promise as a novel class of potential therapeutics. Finally, alternative delivery approaches, dosing, and recombinant forms of AAT protein are in ongoing testing and could result in improved efficacy and quality of life for patients.
The rapid progress made in the application of emerging therapies to AATD is in no small part the result of A1F funding. A1F support laid the groundwork that made it possible to identify approaches that were likely to succeed, demonstrate efficacy in preclinical models, and is enabling their successful testing and application for patients suffering from AATD. Over a 25 year period, A1F-funded researchers have established a broad understanding of the disease, ranging from basic disease mechanisms to the clinical experience of affected patients.
This knowledge base is now being applied in many ways for trial design and implementation, from identifying which patients with AATD are most likely to benefit from specific therapeutic approaches to determining how to measure the success of drugs in development.
In addition to direct funding of research in the form of grant support, the A1F has invested significantly in infrastructure designed to facilitate and promote the success of the aforementioned clinical trials. This support includes:
The Alpha-1 Research Registry: The Alpha-1 Research Registry includes data from more than 4,000 individuals including >1,300 with severe AATD. In addition to its utility as a tool for investigators to address questions of natural history, the registry helps to connect patients with clinical studies that they may qualify for based on their demographic and clinical characteristics. Registry staff have been successful in helping to recruit Alphas to participate in ongoing clinical trials of emerging therapeutics.
The Therapeutic Development Network (TDN): To identify patients interested in participating in clinical trials and who live in proximity to clinical trial sites as a complement to the Alpha-1 Research Registry, the A1F created the TDN. The TDN consists of 20 centers across the US that have agreed to participate in upcoming clinical trials. Each site enrolls local patients and collects a set of data about each enrolled participant that includes the basic inclusion and exclusion criteria for most clinical trials. The resulting database is then a resource for identifying potential clinical trial participants across the country.
The Alpha-1 Biomarkers Consortium (A1BC): In order to design and execute clinical trials, industry partners need biomarkers that are established and recognized by the FDA to correlate with disease severity and progression. The A1BC is a consortium of A1F Clinical Resource Centers (CRCs) funded by the NIH and A1F that has enrolled > 270 severely deficient (ZZ) patients. These centers are collecting longitudinal data and biosamples from this cohort to develop the biomarkers that can then be used as clinical trial endpoints.
The DNA and Tissue Bank: Established in 2001, the bank includes a data repository together with plasma samples and genomic DNA from 2,849 participants, including 812 ZZ, 501 MZ, 88 SZ, 115 MS, and 342 rare alleles. This resource provides the ability to connect DNA sequence with disease phenotype and clinical characteristics and is a tool for addressing research questions about the genetic basis of AATD.
As we look to the future, we see many reasons for optimism. Much of this optimism relates to the clinical trials that have recently started and are anticipated to start in the upcoming 24 months. To ensure that the promise of this moment is realized, A1F will take the following actions in the next 5 years:
Facilitate the success of clinical trials: To ensure the success of clinical trials, we will take several key steps: First, we will continue to support the A1BC and its efforts to identify radiologic and serum biomarkers associated with specific disease states that can similarly inform clinical trials. Second, we will continue to invest in the Alpha-1 Research Registry and the TDN. Finally, we will continue our partnership with the Critical Path Institute and our industry partners to establish endpoints that the FDA will embrace in clinical trials.
Increase detection of Alphas: It is estimated that only 15% of severely deficient patients with AATD have been identified. It is critical that we increase the detection of Alphas both to facilitate clinical trial enrollment and also to identify severely deficient patients earlier in the course of disease when they are more likely to benefit from treatment. To increase detection, we will continue our recent investment in AlphaDetect, a new non-profit subsidiary of A1F, that will lead a transformative initiative that unifies all community stakeholders – patients, healthcare providers, advocates, and industry partners – with a collective common purpose: to ensure no Alpha-1 patient is left undetected.
Invest in research infrastructure: By developing tools that facilitate the ability of researchers to ask questions, we can increase their ability to make discoveries that will benefit Alphas in the years to come. To do so, we will continue to build the natural history component of the Alpha-1 Research Registry to enhance its value for research purposes. We will likewise continue to build genetic data capabilities to facilitate the ability to connect genotypes to phenotypes and continue to invest in human capital through support for the careers of early-stage investigators to sustain a pipeline of scientific expertise in AATD. Finally, we will continue to fund cutting edge research that will produce discoveries that will enable development of the next generation of treatments for AATD.
Increase CRC availability to patients: To get the best care available, patients need access to physicians and allied health professionals with AATD expertise. To increase the availability of such expertise, we will continue to identify and cultivate physicians with AATD expertise, in particular those specializing in pediatric gastroenterology and adult gastroenterology. We will specifically work to increase the number of Clinical Resource Centers in areas of the country that are currently less well represented.
In summary, A1F is working on many fronts and will continue to do so to accomplish the best possible outcomes for Alphas to achieve our mission of finding a cure for Alpha-1.

The Alpha-1 Foundation (A1F) is committed to finding a cure for Alpha-1 Antitrypsin Deficiency (Alpha-1) and to improving the lives of people affected by Alpha-1 worldwide.
