"IDE574 is a promising potential first-in-class molecule that potently inhibits two tumor-promoting epigenetic modulators, KAT6 and KAT7, while sparing other structurally similar KAT family members. Preclinical studies demonstrate KAT6 and KAT7 collaboratively control lineage-specific tumorigenic transcription factor activity essential for tumor cell proliferation and survival. Dual KAT6/7 inhibition by IDE574 disrupts tumor lineage identity and delivers robust anti-tumor activity in patient-derived lung and breast cancer xenograft models dependent upon lineage-specific transcription factor activity," said Michael White, Ph.D., Chief Scientific Officer of IDEAYA Biosciences.

IDE574 is an equipotent, highly selective, small molecule dual inhibitor of the lysine acetyltransferase (KAT) 6 and 7, both of which have been shown to support cancer cell survival. IND-enabling studies support the potential clinical evaluation of IDE574 monotherapy in patients with hormone receptor-positive breast cancer, lung adenocarcinoma as well as additional opportunities associated with lineage addiction. IDEAYA is targeting to share data from its preclinical work with IDE574 at a medical conference in the first half of 2026.

Clinical trial context and objective
CCA is a rare and aggressive cancer of the bile ducts, often diagnosed at an advanced stage. The unmet medical need is characterized by strong limitations in current treatments and poor prognosis. GNS561 is an investigational small molecule that targets PPT1, leading to autophagy inhibition and lysosomal dysfunction, which disrupt cancer cell survival mechanisms. By blocking autophagy, GNS561 aims to promote cancer cell death and may enhance sensitivity to other treatments. Combining GNS561 with a MEKi aims to unlock synergistic potential by simultaneously targeting autophagy and MAPK signaling pathways. In the on-going Phase 1b study, patients with advanced KRAS mutated CCA who have previously failed one or two lines of prior standard of care therapies are enrolled to evaluate the safety and tolerability of GNS561 when given in combination with trametinib, a MEKi, and to identify the recommended doses of the combination to be administered in Phase 2.

Preliminary results
The analysis evaluated 9 patients with measurable disease at baseline, 4 of them reaching tumor assessment at week 6. At this point, the combination therapy demonstrated:

Disease stabilization observed in all 4 evaluated patients, who had all shown disease progression during previous treatment;
Tumor shrinkage in a subgroup of patients with the best response showing a 20% reduction approaching the partial response (PR) threshold.
Achieving disease control and tumor reduction in such heavily pretreated patient population with advanced CCA is a significant signal of antitumor activity.

Clinical Impact

The results to date show a potential to address a critical unmet medical need in oncology. Patients with advanced solid tumors who have progressed on multiple prior therapies have limited treatment options and poor prognoses. The ability of the investigational drug GNS561 associated with a MEKi to achieve disease control in this challenging patient population would represent a significant advance. The consistent pattern of disease stabilization observed across all evaluated patients, combined with objective tumor shrinkage in a subgroup of heavily pretreated patients, suggests the combination has the potential to provide meaningful clinical benefit. Optimization of dosing and patient selection could lead to further improvement in response rates.

Dr. Mark Yarchoan, Associate Professor of Oncology at John Hopkins Medicine (Baltimore, MD, USA), principal investigator of the program, commented: "Advanced KRAS-mutated cholangiocarcinoma remains a formidable clinical challenge, and the emerging activity seen in this initial study is encouraging. Because MEK inhibition alone has historically shown limited efficacy in this setting, the early signs of benefit with dual targeting of autophagy and MAPK signaling provide meaningful rationale for continued evaluation of this combination strategy."

Pascal Prigent, Chief Executive Officer of GENFIT, added: "These early results suggest a potential breakthrough for patients with limited options, and we are committed to advancing this program rapidly to individuals impacted by cholangiocarcinoma. We will also explore GNS561 potential in combination with other agents and in other tumors where autophagy inhibition plays a central role."

Next development steps

Phase 1b dose escalation will continue as planned to confirm the activity signal, with new data for the next patient cohorts expected in 1Q26. These results will be used to establish the recommended Phase 2 combination doses, with completion expected in 1H26. Phase 2 initiation is targeted for 2H26.

The acceptance of four abstracts this year, each showcasing results achieved with IceCure’s technology, represents another significant international recognition of the effectiveness and growing adoption of ProSense by the medical community for the treatment of breast cancer.

"The broad range of independent studies conducted, peer reviewed, published and presented by ProSense users supports the widescale adoption of our cryoablation system and is highly encouraging for women who seek a non-surgical option," said Eyal Shamir, IceCure’s Chief Executive Officer. "At RSNA 2025, radiologists from across the U.S. and the globe gathered to learn about the latest technologies that can lead to better patient outcomes, and we are proud that ProSense was presented to these doctors. We continue to see growing interest in ProSense following the U.S. Food and Drug Administration’s ("FDA") recent marketing approval in low-risk breast cancer."

Independent studies presenting data on ProSense included the following:

1. Abstract Title: Ultrasound-guided Cryoablation for Breast Cancer in Non-Surgical Patients

Key Finding: PCA was successful in 100% of luminal cancers up to 2.5 cm

Researchers (Spain): Laura Abelairas Lopez, MD, Lucia Grana Lopez, MD, Laura Lopez, MD, Ignacio Fernandez Sobrado

Purpose: To present a single-center experience on the use of percutaneous cryoablation ("PCA") for the local control of breast cancer ("BC") in patients who elect not to undergo a surgery or were considered inoperable

Results: 73 women who were considered inoperable were treated under local anesthesia with PCA. 69 of them (median age 87 years, range 48-98 years) had at least one imaging examination performed 6 months after the procedure. Median tumor size was 23 mm, range 6-46 mm. The mean follow-up was 19.8 months (range 6-45 months). 60 patients were luminal BC, 3 were Her2 (+) and 8 were triple negative tumors. All luminal cancers received endocrine therapy. Complete tumoral necrosis was achieved in 56 tumors (81.2%). There was axillary progression in two triple negative BC. Recurrence in a different location was diagnosed in two patients. PCA was successful in 100% of luminal cancers up to 2.5 cm. No major complications were seen and the procedure was well tolerated.

Conclusions: Percutaneous cryoablation is a minimally invasive procedure, without significant complications. It could be a safe alternative to surgery for the management of early-stage breast cancer.

2. Abstract: Non-Surgical Treatment of Breast Cancer: A Comparison of Outcomes Between Cryoablation with Hormonal Therapy Versus Cryoablation Alone and Hormonal Therapy Alone in Patients Not Eligible for Surgery

Key Finding: Statistically significant difference between the Cryoablation-with-HT and the HT-only groups, expressing the added value of Cryoablation

Researchers (Italy): Federica Di Naro, MD, Sofia Elisabetta Baldi Giorgi, Francesca Pugliese, MD, Sofia Vidali, Tommaso Amadori, MD, Diego De Benedetto, Jacopo Nori Cucchiari

Purpose: To evaluate the most effective non-surgical treatment for breast cancer in surgery-ineligible patients, comparing ultrasound-guided Cryoablation combined with hormonal therapy (HT) versus Cryoablation alone and hormonal therapy alone

Results: 111 patients (mean age 81.2 years, ±11.3) not-suitable for surgery due to comorbidities and/or advanced age were enrolled, with a total of 125 biopsy-confirmed malignant breast lesions. Tumor size reduction was significantly different between the groups (P=0.0005), with greatest reduction in the Cryoablation-with-HT group (83.3%, mean reduction of 13.6 mm), followed by Cryoablation-only (61.7%, mean reduction of 8.2 mm), and HT-only (42.1%, mean reduction of 7.4 mm). Tumors with complete remission (CR, RECIST 1.1) were similar between the Cryoablation-with-HT and Cryoablation-only groups (74.4% and 78.3%, respectively), followed by the HT-only (36.1%). Pairwise comparisons revealed a significant difference between the Cryoablation-with-HT and the HT-only groups for Contrast-Enhanced Mammography ("CEM")-enhancement, size reduction (%), and CR, expressing the added value of Cryoablation (P=0.0041, P<0.0001 and P<0.0001, respectively).

Conclusions: Cryoablation with hormonal-therapy significantly reduces tumor size and residual disease more effectively than therapy alone, making it a promising option for patients not-eligible for surgery.

3. Abstract Title: Correlation of Lesion Conspicuity in Contrast-Enhanced Mammography (CEM) with Tru-Cut Scar Biopsy Results in the Assessment of Ultrasound-Guided Cryoablation Outcome

Key Finding: Significant association between biopsy and lesion conspicuity on CEM

Researchers (Spain): Federica Di Naro, MD, Francesca Pugliese, MD, Sofia Elisabetta Baldi Giorgi, Giuliano Migliaro, MD, Giulia Bicchierai, Chiara Bellini, MD, Jacopo Nori Cucchiari

Purpose: To evaluate the role of lesion conspicuity at 12-month CEM follow-up as a predictor of cryoablation outcome

Results: 79 patients (mean age 85.7 years old, ±6.0) with biopsy-proven malignant breast lesions ≤35 mm, underwent ultrasound-guided cryoablation. Among the 79 patients, 48 (60.8%) underwent both CEM and Biopsy at 12 months. Among them, 35 (61.4%) lesions showed no enhancement. Among the 22 (38.6%) lesions showing enhancement, 6 had low LC, 11 moderate LC, and 5 high LC. A significant fair agreement (Cohen’s Kappa coefficient = 0.32 [95% CI: 0.11-0.52]) between CEM and biopsy was shown. Fisher’s exact test P-value was 0.0003 reflecting a significant association between biopsy and conspicuity. Lesions with absent or low LC correlated with negative histology (B2), while lesions with residual malignant histology (B5) were associated with moderate-high LC. In assessing cryoablation efficacy, CEM demonstrated negative predictive value (NPV) of 100%, Sensitivity of 100%, Specificity of 68.6% and positive predictive value (PPV) of 27.3%.

Conclusions: Lower lesion conspicuity on CEM indicates higher cryoablation success, useful for follow-up.

4. Abstract Title: Imaging Findings After Cryoablation of Breast Cancer: Tips and Tricks to Know That the Procedure was Successful Without Biopsy

Researchers (Spain): Laura Abelairas Lopez, MD, Lucia Grana Lopez, MD, Laura Lopez, MD, Ignacio Fernandez Sobrado

Teaching Points: Described the findings on mammography, ultrasound, and CEM after PCA of breast BC, as well as the signs of residual tumor or recurrence.

In the US, SCLC constitutes about 13% of all lung cancers. In 2025, an estimated 29,500 people in the US will be diagnosed with SCLC.2 Of patients with SCLC, 70% have extensive-stage disease, meaning the cancer has spread throughout one or both lungs and/or to other parts of the body.3 ES-SCLC is an aggressive and difficult-to-treat cancer with limited treatment options. The 5-year survival rate is approximately 3%.3 Most patients with ES-SCLC relapse after initial treatment and the median overall survival with standard-of-care treatments for relapsed ES-SCLC is approximately 8 months.4

This designation follows the recent announcement that risvutatug rezetecan was granted ODD from the European Medicines Agency (EMA) for the treatment of pulmonary neuroendocrine carcinoma, a category of cancer that includes SCLC. It is the fifth regulatory designation for risvutatug rezetecan, exemplifying the potential of this B7-H3-targeted ADC, which is being developed in a range of solid tumours, including lung, prostate and colorectal cancers. Previously, risvutatug rezetecan was granted Priority Medicines (PRIME) Designation by the EMA for relapsed or refractory ES-SCLC and Breakthrough Therapy Designations for relapsed or refractory ES-SCLC and relapsed or refractory osteosarcoma granted by the US FDA.5,6,7

An integral resource for patient-centric cancer R&D

Indivumed’s innovative platform builds on carefully collected and curated surgical tissue samples and comprehensive clinical data to drive patient-centric cancer research and drug development. URMC’s invaluable role includes the collection and processing of high-quality biosamples and clinical patient data, adhering to Indivumed’s rigorous standard operating procedures (SOPs). A key advantage is minimizing ischemia time to under ten minutes, ensuring sample integrity and quality.

Priority of the joint research efforts is the creation of well-characterized, patient-derived tumor models (PDTMs) from the very same samples. These cell models, including classical cell cultures, spheroids, and organoids, combined with data insights subsequently serve to advance and de-risk the process of identification, validation, ligand screening, and development of pharmaceutical molecular cancer targets.

Hartmut "Hucky" Land, PhD, Deputy Director of the Wilmot Cancer Institute, is looking forward to the collaboration: "We have worked with Indivumed successfully in the past and our familiarity with their tissue and multi-omics data approach will provide an excellent foundation. The new project will create greater opportunities to identify new therapeutics and biomarkers, uncover insights on the right target-patient match for clinical decision-making, and thus help advance cancer care."

Focusing on advanced stages of specific entities

The collaboration initially focuses on advanced stages of solid cancers with a high medical need, such as colorectal (CRC), pancreatic (PDAC), lung, and breast cancer, with the potential to expand to other cancer types in the future. Insights gained through this partnership will advance Indivumed’s ongoing research initiatives and asset development, while offering participating clinicians valuable guidance to inform therapeutic decision-making.

"We are thrilled to deepen our collaboration with URMC, significantly enhancing our ability to identify novel cancer therapeutics in a truly patient-centered approach," says Hartmut Juhl, CEO and founder of Indivumed. "We will develop primary tumor models for the testing of novel compounds against targets which have been identified by our unique AI-powered data analytical capabilities to bring novel therapeutics to patients as fast and precisely as possible."

With this agreement, the University of Rochester Medical Center joins the Indivumed Global Clinical Network, which already includes a sizeable number of renowned hospitals and leading oncology institutes in North America, Europe and Asia. The collaboration builds on the success of previous collaborations with joint research efforts between the two parties, including a recent publication on the discovery of an alternative way to classify distinct types of colon cancer.
