The agreement follows positive final Phase 1 results in which the investigational vaccine met all primary endpoints, was safe and well tolerated at the maximum tolerated dose, and generated protocol-defined immune responses in 74% of participants. Based on these results, Anixa is advancing preparations for a Phase 2 clinical trial.

Anixa’s breast cancer vaccine, developed in collaboration with Cleveland Clinic, targets α-lactalbumin—a lactation-associated protein that is typically expressed only in breast tissue during lactation, but which re-emerges in many forms of breast cancer. By generating an immune response against α-lactalbumin-expressing cells, the vaccine is designed to potentially provide both therapeutic and preventive benefits for patients with tumors expressing this protein. The vaccine is based on preclinical research led by the late Vincent Tuohy, Ph.D., who served as the Mort and Iris November Distinguished Chair in Innovative Breast Cancer Research at Cleveland Clinic.

Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences, commented, "With final Phase 1 data demonstrating safety, tolerability, and strong immune responses in 74% of participants, we are focused on advancing this program toward Phase 2. Our agreement with Cytovance represents an important operational milestone as we work to secure cGMP clinical supply for the next stage of development." Dr. Kumar continued, "As we advance toward the Phase 2 trial, we expect to provide near-term updates on our progress."

"We are pleased to partner with Anixa to manufacture clinical materials for its Phase 2 breast cancer vaccine trial," said Ping Zhang, CEO of Cytovance Biologics. "Our team is committed to delivering high-quality cGMP manufacturing solutions that support innovative biotech programs. We look forward to leveraging our development and production capabilities to help advance this promising immunotherapy candidate."

Safusidenib is a novel, oral, potent, brain-penetrant, selective inhibitor of mutant IDH1 that is currently being evaluated in the ongoing Phase 3 SIGMA study for the maintenance treatment of patients with IDH1-mutant astrocytoma who have high-risk features following standard-of-care.

In Phase 1 and Phase 2 single arm studies, safusidenib has shown encouraging efficacy signals across all IDH1-mutant glioma grades and treatment lines, including durable responses and prolonged progression-free survival that show tumor shrinkage and disease control. In the Phase 1 study in Japan of 47 participants with recurrent or progressive IDH1-mutant glioma with enhancing (predominantly high-grade) and non-enhancing (predominantly low-grade) tumors, safusidenib showed clinical activity in both populations. Data from a Phase 2 study in Japan of safusidenib in 27 patients with chemotherapy- and radiotherapy-naïve grade 2 IDH1-mutant glioma was published online in the November 2025 issue of Neuro-Oncology. The data published reflected a March 10, 2023 data cut-off. As of February 2026, 12 patients in the study remain on treatment with safusidenib with a median follow-up of over 5 years. Nuvation Bio plans to present longer-term data from the Phase 2 study at a future medical meeting.

"We believe safusidenib has immense potential to address significant patient needs in IDH1-mutant glioma, and our current development plan focuses on patient groups with limited or no FDA-approved targeted treatment options. We are thrilled to now have the exclusive global development and commercialization rights to explore this investigational medicine’s potential across these devastating brain tumors," said David Hung, M.D., Founder, President and Chief Executive Officer of Nuvation Bio. "With this agreement now final, we plan to expand the pivotal Phase 3 SIGMA study into Japan, continue to advance the robust global development of safusidenib, and pursue presentation and publication of longer-term data from the Phase 2 study to ensure the scientific community is up to date on these findings."

"The invention of new medicines is at the core of what we do at Daiichi Sankyo and safusidenib is a strong example of our expertise in science and technology," said Yuki Abe, Ph.D., Head of R&D Division in Japan and Head of Research, Daiichi Sankyo. "We continuously evaluate the best approach to accelerate the delivery of promising medicines to patients and we are confident that Nuvation Bio will carry this program forward, utilizing their strong expertise in clinical development and commercialization to explore the full potential of safusidenib for patients with IDH1-mutant glioma."

About IDH1-Mutant Glioma
Gliomas are the most common type of brain cancer in adults worldwide. In the U.S., nearly 2,500 people are diagnosed with IDH1-mutant gliomas each year, of which more than 95% harbor a mutation in the IDH1 gene. Most patients are diagnosed in their 30s and 40s. While patients with IDH1 mutations generally have longer survival times than those with wild-type IDH1, gliomas are not currently curable and prognosis worsens for those with high-risk features, including high grade tumors.

About Safusidenib
Safusidenib is a novel, oral, potent, brain-penetrant, selective inhibitor of mutant IDH1. In Phase 1 and Phase 2 clinical studies, safusidenib delayed disease progression and provided durable responses across grades and risk groups with a favorable risk-benefit profile.

About the SIGMA (G203) Study
SIGMA is a pivotal Phase 3 study that will evaluate safusidenib compared to placebo as a maintenance therapy after standard-of-care in IDH1-mutant astrocytoma with high-risk features. The pivotal portion of the study will enroll approximately 300 patients. Data is anticipated to be available in 2029.

A separate, exploratory, non-pivotal cohort will evaluate safusidenib in participants with grade 3 IDH1-mutant oligodendroglioma who have not yet received chemotherapy or radiotherapy. The primary endpoint is objective response rate. This cohort is expected to enroll approximately 40 patients. Data is anticipated to be available in 2027.

In addition to the strong results in Ariga score, HT-001 demonstrated strong patient benefit across multiple clinically meaningful measures. Over 65% of patients reported meaningful reductions in pain and itching, supporting HT-001’s potential to significantly improve quality of life for patients suffering from dermatologic toxicities, including those associated with epidermal growth factor receptor inhibitor (EGFR) cancer therapies.

Importantly, zero patients required dose reduction or discontinuation of their EGFR inhibitor therapy while receiving HT-001, highlighting the potential for HT-001 to manage dermatologic side effects without interfering with life-saving cancer treatments.

HT-001 was also well tolerated, with no treatment discontinuations reported.

Pharmacokinetic (PK) analysis further demonstrated that HT-001 achieves approximately 99% lower systemic exposure compared to FDA-approved oral therapies, supporting a targeted delivery profile designed to maximize local efficacy while minimizing systemic side effects.

Building on these positive results, Hoth has received regulatory approval in Hungary, enabling expansion of the Phase 2 clinical trial into Europe. The Company anticipates additional regulatory approvals in Spain and Poland, with site activations expected in the near term. In the United States, an additional clinical site is expected to be activated, further accelerating patient enrollment and data generation.

"The achievement of these interim results, combined with strong patient-reported outcomes and the ability to maintain uninterrupted cancer therapy, represents a meaningful advancement for HT-001," said Robb Knie Chief Executive Officer of Hoth Therapeutics. "With over 65% of patients reporting reductions in pain and itching, along with a favorable safety profile and expanding global clinical footprint, we believe HT-001 is well positioned as a differentiated therapy addressing a critical unmet need in oncology supportive care."

Dermatologic toxicities remain a significant challenge for patients undergoing cancer treatment, often leading to discomfort, reduced quality of life, and in some cases treatment modification or discontinuation. HT-001’s ability to demonstrate primary endpoint achievement, meaningful symptom improvement, and zero disruption to EGFR inhibitor therapy may represent a compelling advancement over existing treatment options.
