Flatiron’s presence at ASH (Free ASH Whitepaper) 2025 closely follows their announcement of six new hematology Panoramic datasets, including five B-cell lymphomas and multiple myeloma, which draw from over 505,000 relevant longitudinal patient records in Flatiron’s network. The datasets represent a six-fold increase in cohort sizes when compared to the company’s previously available datasets and lay the evidence foundation that will guide better treatment decisions, accelerate new development, and ultimately improve outcomes for patients with blood cancers.

"The rapid advancements in the treatment of hematologic malignancies have required an incredibly thoughtful approach to research, one that captures the clinical nuance of disease subtypes, rare patient cohorts, novel endpoints, and evolving biomarkers at scale," said Emily Castellanos, MD, MPH, Senior Medical Director and Head of Research Oncology at Flatiron Health. "Our presence at ASH (Free ASH Whitepaper) unlocks answers to questions that are shaping hematology care right now and our six newly launched hematology Panoramic datasets represent a clinical breakthrough, enabling researchers to study the real-world complexity of blood cancer care—from MRD testing patterns to CAR T therapy utilization—with a level of depth and rigor that was previously impossible."

Research highlights include:

Research examining real-world CAR T cell therapy delivery patterns across US oncology practices, including analysis of cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, and healthcare burden—addressing critical gaps in understanding how this transformative therapy is implemented across care settings.
Multiple studies evaluating measurable residual disease testing patterns and their association with clinical outcomes in Philadelphia-negative B-cell acute lymphoblastic leukemia and multiple myeloma, providing insights into the real-world impact of this precision monitoring approach.
EHR-derived datasets from Germany and the United Kingdom providing comprehensive analysis of diffuse large B-cell lymphoma and multiple myeloma management, demonstrating Flatiron’s ability to generate high-quality, multinational real-world evidence.

On November 4, 2025 Defence Therapeutics Inc. ("Defence" or the "Company"), a leading biotechnology company specialized in drug delivery technologies, reported at the World ADC Conference in San Diego, USA, highly encouraging results from its latest preclinical in vivo study evaluating Accum-Kadcyla, a novel version of Genentech/Roche’s marketed ADC Kadcyla (ado-trastuzumab emtansine), in mouse models of HER2-positive breast cancer.

Study Results: 20-Fold Increased Potency at Equivalent Dose

In the comparative in vivo study, Accum-Kadcyla demonstrated a ~20-fold higher anti-tumor efficacy than Kadcyla alone when administered at the same dose (0.5 mg/kg). Tumor growth was significantly halted in the Accum-Kadcyla-treated group, resulting in a durable and near-complete response in most mice while Kadcyla at the same dose (0.5 mg/kg) had no effect on tumor growth. Importantly, 100% of the animals survived throughout the duration of the study with no signs of toxicity, underscoring the excellent tolerability of the treatment.

Implications for Patients and the Industry

These results confirm that Defence’s Accum platform can dramatically enhance the intracellular delivery and potency of ADCs by overcoming endosomal entrapment—a known bottleneck in ADC performance. By increasing the therapeutic payload’s reach inside cancer cells, Accum enables a more efficient drug release and tumor killing, even at lower doses.

This finding is particularly meaningful for patients: the ability to achieve the same or better efficacy at reduced doses translates into a potential reduction in toxicity and side effects, addressing one of the main limitations of current ADC therapies. Practically, it could potentially bring this current second line of treatment to a first line of treatment for the benefit of the patients.

Dr. Maxime Parisotto, Chief Scientific Officer of Defence Therapeutics, commented:

"These results further validate the power of Accum as a transformative technology for ADCs. By amplifying the potency of a clinically proven ADC like Kadcyla by 20 times at the same dose, we demonstrate that Accum can unlock a new generation of safer and more effective targeted therapies for cancer patients."

Next Steps and Commercial Outlook

Following these promising results, Defence Therapeutics plans to expand its Accum-ADC program to additional HER2-positive and HER2-low tumor models and to advance discussions with potential pharmaceutical partners.

High-grade, 2nd line BCG-unresponsive NMIBC patients
Intermediate risk NMIBC in the adjuvant setting
Key Outcomes from the FDA Type B pre-IND meeting (specific study design details to be further discussed with the agency):

In high-grade, 2nd line BCG-unresponsive setting, the FDA stated that a single arm trial might be acceptable in a more refractory patient population.
In the intermediate risk NMIBC setting, the FDA agreed that a proposal to randomize patients post-TURBT to adjuvant NDV-01 vs observation, evaluating a time-to-event endpoint, is generally acceptable.
Further non-clinical studies are not required. FDA indicated that no further non-clinical studies are required to support a 505(b)(2) New Drug Application (NDA).
"The positive outcome of our Type B meeting and alignment with the FDA on the Phase 3 pivotal program mark a key milestone for Relmada and NDV-01," said Raj Pruthi, MD, Chief Medical Officer – Urology, Relmada Therapeutics. "We believe the FDA’s guidance provides a path to advance NDV-01 for patients with NMIBC who currently have limited options. We believe a single-arm registrational study in high-grade, refractory BCG-unresponsive patients offers a rapid route to potential approval, while alignment on a separate second pivotal study in intermediate-risk NMIBC could enable an additional indication and broader clinical adoption."

Sergio Traversa, Chief Executive Officer of Relmada Therapeutics, stated: "We added NDV-01 to our portfolio based on its strong potential to transform the treatment of NMIBC. The outcome of our Type B meeting with the FDA further reinforces our confidence in the path forward and in NDV-01’s potential to become a best-in-class, durable, ready and easy-to-use, in-office, bladder-sparing therapy. We look forward to initiating the Phase 3 programs in the first half of 2026."

Also, Relmada announced 9-month follow-up data from the Phase 2 study of NDV-01 in non-muscle invasive bladder cancer.

Kris Vaddi, Ph.D., Chief Executive Officer of Prelude stated, "We’re pleased to put this agreement in place with Incyte, recognized global leaders in the MPN field. Prelude and Incyte both aim to deliver transformational treatments to improve upon the standard of care established with first generation JAK2 JH1 inhibitors like Jakafi (ruxolitinib). Our research team made significant progress discovering the first known inhibitors that bind into the JAK2 JH2 ‘deep pocket’ where the V617F mutation resides. These potent and orally bioavailable compounds demonstrate mutant specific inhibition and the potential for disease modification in multiple preclinical models of MPNs. Today’s agreement with Incyte provides us with the capital needed to advance further our JAK2V617F program, while also allowing us to advance the development of our other pipeline programs."

"The agreement with Prelude provides an opportunity to enhance our robust portfolio of clinical and preclinical JAK2V617F candidates for patients with MPNs," said Bill Meury, President and Chief Executive Officer of Incyte. "This transaction aligns with our strategy to develop new and innovative therapies poised to make a meaningful difference for patients."

Terms of the Agreement
Under the terms of the Transaction Agreement, Incyte secures an exclusive option to acquire Prelude’s mutant selective JAK2V617F JH2 inhibitor program, including Prelude’s library of preclinical candidates. Prelude will receive $60 million in capital, comprised of an upfront payment of $35 million, plus a $25 million equity investment by Incyte in Prelude. Incyte will purchase 6.25 million shares of Prelude non-voting common stock at a price of $4.00 per share at deal close. Prelude intends to apply the upfront payment and net proceeds from the sale of the purchased shares to advance the JAK2V617F program and other pipeline assets, and for working capital and general corporate purposes.

Prelude expects to advance the JAK2V617F program to pre-defined milestones. Incyte may elect to exercise its exclusive option during the option period to acquire the program and associated assets from Prelude for $100 million. As the JAK2V617F program candidates advance in the clinic, Prelude would be eligible to receive up to $775 million in additional clinical and regulatory milestones, and single digit royalties on global net sales. Combined, total potential cash payments from the transaction, excluding royalties, could reach up to $910 million.

If Incyte elects to not exercise its option to acquire the program, all JAK2V617F global program rights and interests would remain in the sole ownership and control of Prelude.

Prelude Therapeutics was advised on the transaction by Morgan Lewis & Bockius LLP as legal counsel.

Mutant selective JAK2V617F JH2 inhibitor program
JAK2V617F is the primary driver mutation responsible for disease progression in the majority of patients living with myeloproliferative neoplasms (MPNs). The mutation impacts approximately 95% of patients with polycythemia vera (PV), 60% of patients with essential thrombocythemia (ET) and 55% of patients with myelofibrosis (MF). Identifying JAK2 JH2 inhibitors that selectively target V617F+ cells has long been a shared goal and challenge for industry. If successful, this approach has potential to reduce mutant allele burden, modify disease progression, and transform treatment outcomes for MPN patients. Prelude has discovered novel allosteric inhibitors that bind into the JAK2 JH2 "deep pocket" where the V617F mutation resides. These candidates demonstrate mutant specific inhibition in multiple preclinical models of MPNs. The first disclosure of program data was accepted for oral presentation at the American Society of Hematology (ASH) (Free ASH Whitepaper) 67th Annual Meeting taking place in Orlando, FL December 6-9, 2025. The abstract can be found on the ASH (Free ASH Whitepaper) 2025 website ASH (Free ASH Whitepaper) Annual Meeting & Exposition – Hematology.org.
