"The strategy to engage the immune system with a specific T‑cell engager and deliver a potent cytotoxic payload with a DLL3‑targeting ADC, aligns with our immuno‑oncology strategy and our drive to advance smart combinations for hard‑to‑treat cancers," said Itziar Canamasas, Ph.D., Global Head of Oncology at Boehringer Ingelheim. "It’s another step in our mission to expand effective options for people with DLL3‑expressing cancers."

"Zoci has shown encouraging activity and good tolerability in SCLC," said Rafael G. Amado, M.D., President, Head of Global Research and Development at Zai Lab. "We have rapidly advanced zoci into pivotal stage and are pursuing opportunities to explore multiple combination approaches in SCLC and other NECs. This collaboration with Boehringer Ingelheim offers a compelling DLL3‑targeting strategy with the potential to benefit patients who urgently need better treatments."

Obrixtamig is Boehringer Ingelheim’s investigational bispecific DLL3/CD3 T‑cell engager, designed to direct the body’s own immune cells to attack DLL3‑expressing cancer cells, a hallmark of SCLC and certain NECs. In the global Phase I first‑line ES‑SCLC study DAREON‑8, in combination with chemotherapy and atezolizumab, obrixtamig showed encouraging signs of early clinical efficacy and a manageable safety profile1. Obrixtamig is being evaluated across multiple global studies and is advancing into a global Phase III trial (DAREON‑Lung‑1, NCT07472517). The molecule has received FDA Fast Track Designation and Orphan Drug Designation from both the FDA and the European Commission for neuroendocrine carcinomas.

Zocilurtatug pelitecan is Zai Lab’s DLL3targeting ADC engineered to deliver a potent cytotoxic payload to DLL3positive tumor cells in ES-SCLC. Updated global Phase I results in previously treated ES-SCLC show strong and durable responses, including in patients with brain metastases, along with a favorable safety profile. On this basis, the program has advanced into a global Phase III registrational study. In addition to SCLC, zoci is being evaluated in NECs. Zoci has received FDA Orphan Drug Designation and FDA Fast Track Designation for the treatment of SCLC.

Under the terms of the agreement, Zai Lab will supply its DLL3‑targeting ADC for the study, while Boehringer Ingelheim will sponsor and oversee day‑to‑day clinical operations. Each company retains the rights to its respective assets.

RedTail is Calidi’s systemically delivered virotherapy platform designed to selectively target tumors, remodel the tumor microenvironment (TME), and enable high-level expression of therapeutic genetic payloads directly at the tumor site while limiting peripheral exposure. CLD-401, the lead candidate derived from the RedTail platform, is engineered to express high levels of IL-15 superagonist (IL-15 SA), a known T and NK-cell activator, in the TME. The Company expects to file an IND for CLD-401 by the end of 2026. Additionally, Calidi is expanding the RedTail platform to enable in situ expression of T-cell engagers (TCEs) in solid tumors, including in combination with T-cell activating payloads such as IL15 SA. This strategy is intended to support localized T-cell engagement within the TME following systemic administration. The Company is developing CLD-501, a RedTail virus that expresses high levels of a TROP2-targeting TCE and IL-15SA in the TME.

"I look forward to discussing the advances we’ve made with the RedTail platform and the path to IND filing expected this year for CLD-401" said Eric Poma, PhD, Chief Executive Officer of Calidi. "We continue to expand what the RedTail platform can do with new payload, a novel approach to in situ T-cell engagers, and ongoing lead discovery in indications outside of oncology."

The Company continues to expand the functionality of the RedTail platform and is also actively pursuing strategic partnerships to accelerate clinical development and broaden the impact of its RedTail platform.

"Structural variants are an important driver of cancer biology, and Arima is focused on bringing that dimension into cancer genomics," said Anthony Schmitt, PhD, Senior Vice President of Science at Arima Genomics. "The data we will present at AACR (Free AACR Whitepaper) reflect the breadth of that opportunity across solid tumors."

The presentations include data demonstrating Arima’s ability to detect structural variants in lung and gastrointestinal tumors, showing concordance with traditional methods while also identifying variants those methods may miss. That capability, demonstrated across multiple studies, underpins Arima’s Aventa FusionPlus clinical assay. Additional presentations demonstrate the ability to detect and predict the functional impact of enhancer hijacking rearrangements and extrachromosomal DNA (ecDNA) amplifications in non-small cell lung cancer (NSCLC). A fifth presentation extends Arima’s work in fusion and rearrangement detection into gynecologic carcinosarcoma through analysis of aberrations involving genes potentially linked to homologous recombination deficiency (HRD). Together, the AACR (Free AACR Whitepaper) data show the range of biological and clinical questions that a structural variant-focused approach can address.

"These studies show how Arima’s technology provides a new lens with which to view the cancer genome in a way that no other technology can," said Tom Willis, PhD, Chief Executive Officer of Arima Genomics. "We are already putting this approach to work for patients through our Aventa clinical tests, while continuing to build the evidence and applications that support a more complete view of cancer."
