Acceptance for a poster presentation at the SITC (Free SITC Whitepaper) Annual Meeting underscores the scientific rigor and innovation behind HCB301’s development. SITC (Free SITC Whitepaper) is the world’s largest annual conference solely dedicated to cancer immunotherapy. Each year, more than 1,300 abstracts are submitted, evaluated according to rigorous selection criteria based on research quality, novelty, and their potential to advance cancer immunotherapy.

Presentation Details

The accepted abstract, titled "A Novel Tri-Specific Fc Fusion Protein Targeting PD-L1, CD47, and TGFβ Remodels the Tumor Microenvironment and Enhance Anti-Tumor Immunity", will be presented on Saturday, November 8, 2025. The presentation will highlight preclinical efficacy and safety data supporting HCB301’s potential as a first-in-class immune-enhancing biologic that targets key mechanisms of tumor immune evasion.

"We are honored to present these compelling preclinical data at SITC (Free SITC Whitepaper) 2025," said Wenwu Zhai, Chief Scientific Officer of HanchorBio. "HCB301 exemplifies the power of our FBDB platform to rationally design multi-specific biologics that restore immune activity and deliver enhanced anti-tumor responses."

About HCB301

HCB301 is a tri-functional IgG4 Fc fusion protein that incorporates:

An anti-PD-L1 antibody,
A high-affinity SIRPα variant to disrupt CD47-mediated "don’t eat me" signaling, and
A TGF-βRII trap domain.
Following successful preclinical development, HCB301 is now in a Phase 1 multi-regional clinical trial in the U.S. and Taiwan to evaluate its safety, tolerability, and anti-tumor activity in patients with advanced solid tumours.

In preclinical studies, HCB301 demonstrated:

Potent blockade of PD-L1 and TGF-β signaling,
Robust phagocytosis of CD47+ tumor cells in vitro with minimal red blood cell binding, suggesting an improved hematologic safety profile compared to CD47-targeting analogs, and
In vivo efficacy comparable to a triple-agent cocktail across multiple xenograft models.
The abstract will also be published in the Journal for ImmunoTherapy of Cancer (JITC) in February 2026 as part of the SITC (Free SITC Whitepaper) 2025 Final Supplement.

On October 3, 2025 Icecure Medical reported that the U.S. Food and Drug Administration ("FDA") has granted marketing authorization for ProSense, a minimally invasive cryoablation treatment for patients with early-stage low risk breast cancer when combined with adjuvant endocrine therapy for women aged 70 and over, an estimated population of 46,000 women annually in the U.S (Press release, IceCure Medical, OCT 3, 2025, View Source [SID1234656426]). The announcement was made on October 3, 2025, by IceCure Medical Ltd. (Nasdaq: ICCM) ("IceCure", "IceCure Medical" or the "Company"), the developer of minimally invasive cryoablation technology that destroys tumors by freezing as an option to surgical tumor removal.

"We are excited to add a minimally invasive choice around breast cancer treatments and to offer patients an effective, outpatient procedure," said Eyal Shamir, Chief Executive Officer, IceCure. "With the ProSense Cryoablation System, we are giving women with low-risk, early-stage breast cancer the choice to freeze their cancer, not their lives, through an effective treatment that minimizes recovery time, and minimal cosmetic changes to the breast."

ProSense is the first and only medical device to be granted FDA marketing authorization for the local treatment of breast cancer.

ProSense is authorized by the FDA for the local treatment of breast cancer in patients ≥70 years of age with biologically low-risk tumors ≤1.5 cm in size and treated with adjuvant endocrine therapy. Biologically low-risk breast cancer is defined as unifocal tumor, size ≤1.5cm, ER+, PR+, HER2-, Ki-67<15% and/or genomic testing indicative of low-risk breast cancer, infiltrating ductal carcinoma (excluding lobular carcinoma, extensive intraductal component, or evidence of lymphovascular invasion), and clinically negative lymph node (N0). The authorized indication includes patients that are not suitable for surgery for breast cancer treatment. For a complete discussion of the benefits and risks of ProSense Cryoablation System for the local treatment of breast cancer, please visit our website.

In granting marketing authorization, the FDA requested that IceCure conduct a post-market surveillance study with the aim of producing additional data in this indication. The post-market study is expected to include approximately 400 patients at 30 sites.

Breast cancer cryoablation with ProSense, is a simple, quick, out-patient procedure that can have a notably positive impact on the patient experience and can be beneficial for patients seeking more choices.

"You don’t need any kind of cosmetic follow-up, you don’t have a scar, and you don’t have the feeling of having lost part of your breast, because it’s all still there," said breast cancer patient and ICE3 trial participant, Pam Dixon, when describing her experience with the ProSense cryoablation procedure. "There was no pain. It was one of the easiest things I’ve ever done. I don’t remember any limitations on my activity."

During the ProSense cryoablation procedure, a doctor injects local anesthesia and uses ultrasound imaging to guide a small cryoprobe, a thin hollow needle, into the breast tumor. Once the cryoprobe is placed, liquid nitrogen creates extremely cold temperatures (-170C°) which destroys the breast tumor by creating an ice ball around the targeted tissue. Key advantages of ProSense cryoablation procedure include:

Maintain breast shape: No tissue is removed and there is minimal scarring from the insertion of the cryoprobe. No breast reconstruction is needed.

Short, out-patient procedure with local anesthesia: Average cryoablation procedure time is approximately 30 – 45 minutes with no hospital waiting or overnight stay. Numbing agents (local anesthesia) are injected only into the area being treated and the ice formed during the procedure has a numbing effect.

Reduced recovery time: Patients typically return to normal activity within 24-hours. Median recovery time is one day with a range of 0 – 8 days.

The procedure is monitored in real-time by ultrasound to ensure the ice ball is growing sufficiently around the tumor, and to avoid damage to the skin or muscle. The doctor may use hydro-dissection to protect the skin or muscle during a procedure depending on the location of the tumor. The tissue destroyed by the ice ball is naturally reabsorbed by the body over time and adjacent tissue is left unharmed.

The FDA’s marketing authorization was based on an abundance of data including IceCure’s ICE3 trial which was published in the Annals of Surgical Oncology. With 194 patients, ICE3 is the largest multi-center clinical trial ever completed for liquid-nitrogen (LN2) based cryoablation for patients aged ≥60 with low-risk, early-stage breast cancer without surgically removing the breast tumor. Only 3.1% of patients with hormone receptor-positive and HER2-breast cancer treated locally with cryoablation and endocrine therapy (also known as hormone or hormonal therapy), experienced local recurrence of breast cancer within 5 years after treatment, based on the study results.

The majority of the cryoablation procedure-related adverse events besides breast cancer recurrence were edema (swelling), bruising, hematoma (bleeding into tissues), skin burn, and postoperative pain. These were mild in severity and all of these events resolved without any permanent effect.

ICE3 study lead author, Richard Fine, MD, FACS, of the West Cancer Center & Research Institute in Germantown, TN and past President of the American Society of Breast Surgeons emphasizes that, "The ICE3 study has proven that cryoablation with ProSense is a safe, minimally invasive ablative procedure with results similar to that of lumpectomy patients who took endocrine therapy, and has the benefit of being an office-based, non-surgical treatment. Further data coming out of the post-market study should continue to support that cryoablation with ProSense is a successful option in the de-escalation of breast cancer care in appropriately selected patients."

The National Comprehensive Cancer Network (NCCN) recently updated the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for SCLC to include the combination as preferred regimen for patients whose disease has not progressed following four cycles of platinum-based chemotherapy and atezolizumab induction.

The FDA approval is based on results from the Phase 3 IMforte trial, which showed that the lurbinectedin and atezolizumab combination reduced the risk of disease progression or death by 46% and the risk of death by 27%, compared to atezolizumab maintenance therapy alone. Following four cycles of induction therapy, from the point of randomization the median overall survival (OS) for the combination regimen was 13.2 months versus 10.6 months (stratified hazard ratio [HR]=0.73; 95% CI: 0.57–0.95; p=0.0174). From the point of randomization, median progression-free survival (PFS) by independent assessment was 5.4 months versus 2.1 months, respectively (stratified HR=0.54, 95% CI: 0.43–0.67; p<0.0001). Safety was consistent with the known safety profiles of both treatments. The results were presented at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting and simultaneously published in The Lancet.

PharmaMar has also submitted a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA), which is currently under review.
