"This paper validates two fundamental realities in targeted cancer drug discovery: genetic targeting opportunities discovered in cell lines are more likely to hold up in the clinic when caused by a driver mutation, and drugs behave very differently from genetic knockouts, so screening them against the causal biology is essential," said Tomas Babak, Ph.D., Founder and Chief Scientific Officer of Leapfrog Bio and co-author on the publication. "Our OncoSLX platform is built on these principles and allows us to run thousands of these drug-mutation tests against all cancer driver mutations simultaneously, quickly identifying potent, genetically targeted treatments for LOF cancers."

Dr. Babak continued, "By screening clinically safe drugs, we can restart development in Phase 2 in genetically selected patients where the probability of efficacy is higher. We expect this approach to be significantly accelerating and derisking as we advance through development."

"Leapfrog Bio was founded to bring the transformative benefit of precision medicines to the many patients with cancers caused by LOF mutations, for whom targeted options are limited," said Greg Vontz, Chief Executive Officer of Leapfrog Bio. "Among our most promising discoveries to date is the vulnerability of EP300 LOF cancers to BET inhibitors, like our lead candidate, LFB190. Leveraging learnings from our OncoSLX platform, we are positioned to advance LFB190 directly into mid-stage development. We look forward to initiating our planned Phase 1b/2a trial in mid-2026."

LFB190 is an oral, small-molecule, potentially best-in-class BETi in development for the more than 60,000 U.S. patients annually who are diagnosed with EP300-mutated solid tumors, including non-small cell lung, bladder, colon, pancreatic, head and neck, and bile duct cancers. While BET inhibitors have been widely studied across cancer indications, they have shown limited efficacy in genetically unselected populations. Extensive preclinical studies have shown that BET inhibitors can be highly effective when used to treat EP300-driven cancers, and previous clinical development of LFB190 as an untargeted therapy has shown favorable safety and tolerability for the drug.

About OncoSLX Platform
OncoSLX Platform is Leapfrog Bio’s proprietary pharmacogenetic platform that screens clinically characterized small molecules against isogenic models of cancer driver mutations, focusing on loss‑of‑function biology. Unlike traditional synthetic‑lethality approaches based on gene knockouts, OncoSLX captures the full spectrum of drug biology and then integrates real‑world outcomes data to prioritize indications likely to deliver survival benefit, compressing timelines and reducing translational risk. This approach identifies novel treatments for loss-of-function-driven cancers that cannot be discovered by conventional methods.

About LFB190 and EP300-Mutated Cancers
LFB190 is a novel, oral BET inhibitor for the treatment of solid tumors driven by EP300 loss-of-function (LOF) mutations. Leapfrog Bio’s OncoSLX Platform has identified a novel synthetic lethality relationship between BET inhibitors and EP300 LOF mutations, which are a known and frequent cancer driver with no targeted therapy available. LFB190 has shown strong preclinical efficacy in patient-derived xenograft (PDX) models of EP300-mutated cancers. EP300 is a tumor suppressor gene involved in chromatin remodeling and transcriptional regulation. When mutated, its loss contributes to tumor progression across multiple cancer types, including approximately 6 percent of non-small cell lung cancers (NSCLC), approximately 15 percent of bladder cancers, and similar frequencies in colon, pancreatic, and head and neck cancers. While BET inhibitors have historically shown limited efficacy in unselected populations, Leapfrog Bio’s platform revealed a compelling effect in EP300-mutated tumors.

The joint venture will advance two ADC programs directed at novel tumor targets discovered by Tahoe using its proprietary Mosaic platform and large-scale, perturbative single-cell datasets. The collaboration reflects a strong strategic fit between Tahoe’s ability to identify high-confidence, tumor-selective targets using its AI-powered virtual cell models and Alloy’s end-to-end capabilities in biologic drug engineering, ADC design, and company creation through its venture studio 82VS.

Over the past year, Tahoe analyzed a subset of its proprietary multi-million-cell datasets and identified tens of tumor-specific surface antigens, many of which had taken decades to discover previously, and most of which are novel. Tahoe subsequently validated the most promising targets across multiple independent assays and clinical samples. After rigorous evaluation, Alloy recognized the exceptional therapeutic potential of these targets, catalyzing the decision to jointly spin out a dedicated ADC development company around two of them.

"We are excited to partner with Tahoe and were immediately impressed by the depth and quality of biological insight generated by the Mosaic platform," said Errik Anderson, Founder and CEO of Alloy Therapeutics. "With our track record of 20 clinical programs discovered with Alloy platforms and services, including multiple drugs in Phase III, we are well positioned to translate the cutting-edge biology from world-class target rich companies like Tahoe into optimized therapeutics."

Under the structure of the joint venture, Tahoe and Alloy will co-invest, co-build, and co-lead the new company. Tahoe will contribute its novel targets and biomarker insights, while Alloy will provide its ADC engineering platforms, translational development expertise, and 82VS company creation infrastructure. Together, the team aims to efficiently advance both ADC programs to key value-inflection points suitable for independent financing or pharma partnerships.

Our datasets and AI models are enabling the discovery of novel targets," said Nima Alidoust, co-founder and CEO of Tahoe Therapeutics. "Alloy, which has had a strong track record in developing first-in-class biologics, shares this excitement with us, and that is a strong validation of the biology discovered by our platform. This joint venture is also a preview of the business model our platform enables: building new companies alongside partners with complementary capabilities."

Combining Tahoe’s AI-powered approach to understanding novel tumor biology with Alloy’s fully integrated drug discovery, development, and company creation capabilities creates a highly efficient path to translate novel biologic insights into first-in-class drugs for patients in need.

On January 12, 2026 Atara Biotherapeutics, Inc. (Nasdaq: ATRA), a leader in T-cell immunotherapy, leveraging its novel allogeneic Epstein-Barr virus (EBV) T-cell platform to develop transformative therapies for patients with cancer and autoimmune diseases, reported that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) for the EBVALLO (tabelecleucel) Biologics License Application (BLA) as monotherapy treatment for adult and pediatric patients two years of age and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD), who have received at least one prior therapy including an anti-CD20 containing regimen.

The CRL indicates that the FDA is unable to approve the EBVALLO BLA in its present form. The BLA was resubmitted in 2025 after reaching alignment with the FDA on the acceptability of the resubmission criteria and fulfilment of the conditions as identified in the first Complete Response Letter dated 15 January 2025 (First CRL). As we previously disclosed, in the First CRL, the FDA identified a single deficiency regarding Good Manufacturing Practice (GMP) compliance and did not raise any concerns with respect to the safety, efficacy or trial design.

In the current CRL, received after market close on 9 January 2026, the FDA confirmed that the GMP compliance issues had been satisfactorily resolved, and importantly, no safety issues were raised. However, in a complete reversal of position by the FDA, the CRL claims that the single arm ALLELE trial, which was previously confirmed by the FDA as adequate to support the BLA filing, is no longer considered to be adequate to provide evidence of effectiveness for accelerated approval. Furthermore, the FDA stated that the trial’s interpretability is confounded due to trial study design, conduct, and analysis.

The FDA’s new position is contrary to the FDA’s prior guidance to Atara, the FDA’s alignment with Atara on the clinical trial data set, and the acceptance of the trial design as a single arm study as relevant for this patient population at BLA submission. This prior alignment had been reached by Atara and the FDA through multiple, documented meetings held over the past five plus years.

In November 2025, Atara transferred the BLA to Pierre Fabre Pharmaceuticals (PFP), Inc., the U.S. pharmaceutical subsidiary of Pierre Fabre Laboratories. As a first step towards resolution, PFP intends to request a Type A meeting and expects it to be granted within 45 days. PFP and Atara plan to urgently interact with the FDA to find a path forward for the timely accelerated approval of EBVALLO without which patients with EBV+ PTLD have extremely limited treatment options and a life expectancy often measured in weeks to months.

"We are surprised and disappointed by this FDA decision for EBV+ PTLD patients who have a significant unmet need, highlighted by tabelecleucel’s Orphan Drug designation and by the granting of Breakthrough status at the time we submitted the ALLELE primary data," said Cokey Nguyen, President and Chief Executive Officer of Atara. "The issues highlighted in the CRL were issues Atara and the FDA aligned on in previous reviews or communications. We had aligned with the agency to accept an Accelerated Approval and to perform a post marketing confirmatory study to support full approval. We proceeded with the BLA submission on this basis and continued all remediation efforts after the resubmission in 2025, in full reliance of the confirmation provided by the FDA. We strongly believe that tabelecleucel can bring substantial benefit to post-transplant lymphoproliferative disease patients, and look forward to addressing the concerns of the FDA clinical review team newly in place alongside our partners."

Corporate and Financial Updates

In December 2025, Atara amended the commercialization agreement with Pierre Fabre Medicament (PFM) to, among other things, mitigate the impact of the cost of rebuilding commercial inventory in the United States. Under the terms of the amendment, Atara agreed to reduce the milestone payment due upon BLA approval to $31 million in exchange for the right to receive an additional $15 million potential milestone payment upon achieving a certain commercial milestone.

Cash, cash equivalents and short-term investments as of December 31, 2025, totaled approximately $8.5 million.

In 2025, Atara implemented significant operational efficiencies, including an approximately 90% reduction in headcount year over year, and transitioned substantially all tab-cel activities and associated costs to Pierre Fabre Laboratories including all regulatory, clinical and CMC responsibilities.

Additionally, in November 2025, we amended our Atara Research Center (ARC) lease agreement reducing our square footage and remaining lease liability by approximately 65%.

This estimate of our cash, cash equivalents, short-term investments and accounts receivable as of December 31, 2025, is preliminary, and has not been audited and is subject to change upon completion of our financial statement closing procedures. Our independent registered public accounting firm has not audited or performed any procedures with respect to this estimate. Additional information and disclosure would be required for a more complete understanding of our financial position and results of operations as of December 31, 2025.
