LIXTE Launches New Study to Determine if Certain Pre-Cancerous Cells Found in an Aging Population Can Be Eliminated by LB-100

On March 31, 2025 LIXTE Biotechnology Holdings, Inc. ("LIXTE" or the "Company") (Nasdaq: LIXT and LIXTW), a clinical stage pharmaceutical company, reported it will conduct a new pre-clinical study in collaboration with Netherlands Cancer Institute (NKI) to test whether "initiated" cells that carry mutations found in cancer cells can be eliminated by treatment with LIXTE’s proprietary compound LB-100 (Press release, Lixte Biotechnology, MAR 31, 2025, View Source [SID1234651678]).

"In addition to our ongoing clinical trials in ovarian and colorectal cancer, this study represents a new opportunity in cancer prevention," said Bas van der Baan, LIXTE’s Chief Executive Officer. "Thus far in our Phase 1 clinical trials, LB-100 has shown patient tolerance, with little toxicity, making it a promising candidate as a broad and effective cancer prevention modality."

Increasing evidence indicates that as individuals age, certain mutations accumulate that are found in cancer cells. While these "initiated" cells behave essentially normally, they can propagate to form reservoirs of pre-malignant cells from which malignant cells may eventually emerge. Recent data from LIXTE’s ongoing clinical collaboration with NKI shows that LB-100 activates oncogenic signaling and that this is detrimental to cancer cells.

The new study in animal models will investigate whether "initiated" cells, harboring a mutant RAS oncogene, can be eliminated with LB-100. If successful, LB-100 could have a significant role in the elimination of initiated cells in aged individuals and could reduce the risk of developing a wide range of cancers as a person ages.

The study will be led by René Bernards, Ph.D., a global leader in the field of molecular carcinogenesis and Senior Staff Scientist at NKI, one of the world’s leading comprehensive cancer centers. Dr. Bernards also is a member of LIXTE’s Board of Directors.

"T cell engagers are an exciting area of immunotherapy that remains in the early innings of development. We believe gamma-delta T cells offer unique properties, including tissue residence, phagocytosis and low IL-6 secretion, representing a powerful modality with the potential to overcome the limitations of current CD-3 based engager therapies," said William Ho, CEO, and co-founder of IN8bio. Our novel gamma-delta T cell engager platform, presented for the first time at AACR (Free AACR Whitepaper) 2025, demonstrates how we can combine the innate tumor-recognition capabilities of gamma-delta T cells with the capacity for significant cell expansion and the specificity of bispecific engagers to drive a potent, targeted immune response against multiple target antigens. These early findings in AML and B-ALL support our broader strategy to harness the unique biology of these cells across a range of cancers."

Despite progress in cervical cancer prevention and early detection, there remains a high need for new treatment options, particularly in advanced forms of the disease. In fact, cervical cancer is the fourth most common cause of cancer death among women globally.i In the European Union, cervical cancer is the 11th most frequently occurring cancer among women.ii Up to 15% of adults with cervical cancer present with metastatic disease at diagnosisiii,iv and, for those diagnosed at earlier stages who receive treatment, up to 61%v will experience disease recurrence. For these patients, the prognosis can be poor.vi

"Recurrent or metastatic cervical cancer is a devastating disease, and patients can face a difficult treatment journey with limited options," said Ignace Vergote, M.D., Ph.D., University Hospitals Leuven, co-founder of European Network of Gynaecological Oncological Trial groups (ENGOT), and lead investigator on the innovaTV 301 clinical trial. "In clinical trials, TIVDAK demonstrated a superior overall survival benefit and manageable safety profile compared to chemotherapy, supporting its position to become a potential new standard of care in this setting with a novel mechanism of action. This approval is an important step forward in the treatment landscape for advanced cervical cancer."

The approval is supported by data from the global, randomized, Phase 3 innovaTV 301 trial (NCT04697628) that evaluated the efficacy and safety of TIVDAK compared to chemotherapy in patients with advanced or recurrent cervical cancer who were previously treated with chemotherapy. The trial met its primary endpoint of overall survival (OS), demonstrating a 30% reduction in risk of death (HR: 0.70 [95% CI: 0.54-0.89], two-sided p=0.0038) compared to chemotherapy. Median OS was 11.5 months [95% CI: 9.8-14.9] among patients treated with TIVDAK compared to 9.5 months [95% CI: 7.9-10.7] for patients who received chemotherapy. Secondary endpoints of progression-free survival (PFS) and confirmed objective response rate (ORR) were also met, further validating its clinical benefit. PFS results were statistically significant, with TIVDAK demonstrating a 33% reduction in the risk of disease progression compared with chemotherapy (HR: 0.67 [95% CI, 0.54-0.82], p<0.0001). Data from the innovaTV 204 (NCT03438396) pivotal Phase 2 single-arm clinical trial evaluating TIVDAK as monotherapy in patients with previously treated recurrent or metastatic cervical cancer was also included in the marketing authorization application (MAA).

The most common (≥25%) adverse reactions, including laboratory abnormalities, in patients receiving tisotumab vedotin were peripheral neuropathy (39%), nausea (37%), epistaxis (33%), conjunctivitis (32%), alopecia (31%), anaemia (27%), and diarrhoea (25%).

"We recognize the urgent need to accelerate science and innovate new treatment options for gynecologic cancers, including cervical cancer," said Brad Bailey, Executive Vice President and Chief Commercial Officer of Genmab. "The European Commission approval of TIVDAK marks a milestone in our work to transform the treatment paradigm and help improve outcomes for patients. As the first medicine that Genmab will bring to patients in Europe independently, we’re committed to bringing this important option to as many patients in Europe with previously treated recurrent or metastatic cervical cancer as possible."

About the innovaTV 301 Trial
The innovaTV 301 trial (NCT04697628) is a global, 1:1 randomized, open-label Phase 3 trial evaluating tisotumab vedotin versus investigator’s choice of single agent chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan or pemetrexed) in 502 patients with recurrent or metastatic cervical cancer who received one or two prior systemic regimens in the recurrent or metastatic setting.

Patients with recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma or adenosquamous histology, and disease progression during or after treatment with chemotherapy doublet +/- bevacizumab and an anti-PD-(L)1 agent (if eligible) are included. The primary endpoint was overall survival. The main secondary outcomes were progression-free survival and objective response rate.

The study was conducted by Seagen, which was acquired by Pfizer in December 2023, in collaboration with Genmab, European Network of Gynaecological Oncological Trial Groups (ENGOT, study number ENGOT cx-12) and the Gynecologic Oncology Group (GOG) Foundation (study number GOG 3057), as well as other global gynecological oncology cooperative groups. For more information about the Phase 3 innovaTV 301 clinical trial and other clinical trials with tisotumab vedotin, please visit www.clinicaltrials.gov.

About Tisotumab Vedotin
Tisotumab vedotin (approved under the brand name TIVDAK in the EU, U.S. and Japan) is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Pfizer’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Nonclinical data suggest that the anticancer activity of tisotumab vedotin is due to the binding of the ADC to TF-expressing cancer cells, followed by internalization of the ADC-TF complex and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.

Lindsay A. Rosenwald, M.D., Fortress’ Chairman, President and Chief Executive Officer, said, "The fourth quarter of 2024 was transformational for Fortress, marked by two FDA approvals — Emrosi and UNLOXCYT — as well as the FDAs’ recent acceptance of the New Drug Application for CUTX-101. Additionally, we congratulate Fortress-founded partner company, Checkpoint Therapeutics, Inc. ("Checkpoint"), as earlier this month they signed an exciting agreement that delivers FDA approved UNLOXCYT into the capable and established global commercial organization at Sun Pharma, which is expected to expedite patient access. This transaction is also a successful milestone for Fortress as we expect to receive approximately $28 million at closing in addition to a 2.5% royalty on net sales of UNLOXCYT, and up to an additional $4.8 million if the contingent value right (CVR) is achieved. These milestones continue to validate the Fortress business model. We aim to acquire and advance assets to their full potential, in this specific case, with an exit strategy that benefits patients and maximizes value for our shareholders."

Dr. Rosenwald continued, "Looking ahead, we are focused on our next key milestone: the September 30, 2025, Prescription Drug User Fee Act ("PDUFA") goal date for CUTX-101. Upon approval of the New Drug Application, our majority-owned subsidiary, Cyprium Therapeutics, may be eligible for a Priority Review Voucher. The commercial launch of Emrosi for inflammatory lesions of rosacea is underway with first prescriptions filled, and we expect continued revenue growth, portfolio milestone achievements and additional future monetization opportunities given our significant pipeline of late clinical-stage candidates and recently approved products. This is an exciting time for Fortress, and we remain committed to building shareholder value while delivering innovative treatment options to patients with unmet medical needs."

Recent Corporate Highlights1:

Monetization Updates

● In March 2025, our subsidiary Checkpoint entered into an agreement to be acquired by Sun Pharmaceutical Industries Limited (together with its subsidiaries and/or associated companies, "Sun Pharma"). Fortress owns approximately 6.9 million shares (including Class A Common on an as-converted basis) of Checkpoint’s common stock and is eligible for a 2.5% royalty on future sales of UNLOXCYT (cosibelimab-ipdl), pursuant to a royalty agreement between Checkpoint, Sun Pharma and Fortress. Upon completion of the transaction, Sun Pharma will acquire all outstanding shares of Checkpoint and Checkpoint stockholders will receive, for each share of common stock they hold, an upfront cash payment of $4.10, without interest, and a non-transferable contingent value right (CVR) entitling the stockholder to receive up to an additional $0.70 in cash if cosibelimab is approved prior to certain deadlines in the European Union pursuant to the centralized approval procedure or in Germany, France, Italy, Spain or the United Kingdom, subject to the terms and conditions in the contingent value rights agreement. The transaction is expected to be completed in the second quarter of 2025. The transaction is subject to customary closing conditions, including required regulatory approvals and approval by the holders of a majority of the voting power of outstanding shares of Checkpoint common stock, and by the holders of a majority of the shares of Checkpoint common stock that are not held by Fortress or by certain other affiliates of Checkpoint. In connection with the transaction, Fortress, which holds a majority of Checkpoint’s outstanding voting power, has agreed to vote in favor of the transaction.
● In July 2024, our majority-owned and controlled subsidiary company Urica Therapeutics ("Urica"), entered into an asset purchase agreement, royalty agreement and related agreements with Crystalys Therapeutics ("Crystalys"). Urica transferred rights to dotinurad, its URAT1 inhibitor product candidate in development for the treatment of gout, and related intellectual property, licenses and agreements to Crystalys. In return, Crystalys issued to Urica shares of its common stock equal to 35% of Crystalys’ outstanding equity and granted Urica a secured 3% royalty on future net sales of dotinurad.

Regulatory Updates

● In November 2024, the U.S. Food and Drug Administration ("FDA") approved Emrosi (Minocycline Hydrochloride Extended-Release Capsules, 40mg), also known as DFD-29. Emrosi has the potential to be the new treatment paradigm for the millions of patients suffering from inflammatory lesions of rosacea. In February 2025, we hosted a webcast to discuss the U.S. commercial launch plan for Emrosi, and in March 2025, we announced the launch of Emrosi by our partner company, Journey Medical Corporation ("Journey Medical") (Nasdaq: DERM).
● In December 2024, the FDA approved UNLOXCYT, also known as cosibelimab, our anti-PD-L1 antibody, as a treatment for patients with metastatic or locally advanced cutaneous squamous cell carcinoma ("cSCC") who are not candidates for curative surgery or radiation. UNLOXCYT was developed at our partner company, Checkpoint (Nasdaq: CKPT).
● The FDA recently accepted the New Drug Application ("NDA") submission for CUTX-101 (copper histidinate for Menkes disease) for priority review with a PDUFA goal date of September 30, 2025. In December 2023, we completed the asset transfer of CUTX-101 to Sentynl Therapeutics ("Sentynl"), a wholly owned subsidiary of Zydus Lifesciences Ltd. Sentynl completed the rolling submission of the NDA for CUTX-101 in the fourth quarter of 2024. Cyprium Therapeutics, our subsidiary company that developed CUTX-101, will retain 100% ownership over any FDA Priority Review Voucher that may be issued at NDA approval.
1 The development programs depicted in this press release include product candidates in development at Fortress, at Fortress’ private subsidiaries (referred to herein as "subsidiaries"), at Fortress’ public subsidiaries (referred to herein as "partner companies") and at entities with whom one of the foregoing parties has a significant business relationship, such as an exclusive license or an ongoing product-related payment obligation (such entities referred to herein as "partners"). The words "we", "us" and "our" may refer to Fortress individually, to one or more of our subsidiaries and/or partner companies, or to all such entities as a group, as dictated by context.

Clinical Updates

● In March 2025, we announced that full results from two Phase 3 multicenter, randomized, double-blind, parallel-group, active-comparator and placebo-controlled clinical trials, Minocycline Versus Oracea in Rosacea-1 ("MVOR-1") and Minocycline Versus Oracea in Rosacea-2 ("MVOR-2"), evaluating Minocycline Hydrochloride Extended Release Capsules, 40 mg ("DFD-29" or "Emrosi") for the treatment of moderate-to-severe papulopustular rosacea in adults were published in the Journal of the American Medical Association – Dermatology. The results demonstrated the efficacy, safety and tolerability of oral DFD-29 in rosacea. The full publication is available at View Source Information on such website is not a part of this release.
● In January 2025, we announced that the first patient was dosed in a multicenter, placebo-controlled and randomized Phase 2 clinical trial to evaluate Triplex, a cytomegalovirus ("CMV") vaccine, when administered to human leukocyte antigen matched related stem cell donors to reduce CMV events in patients undergoing hematopoietic stem cell transplantation.
● In October 2024, clinical data were presented at the 44th Fall Clinical Dermatology Conference assessing the dermal and systemic pharmacokinetics of Emrosi versus oral doxycycline 40 mg capsules (Oracea) in healthy subjects. With its extended-release formulation, Emrosi provides higher dermal concentration than doxycycline from day 1 onward at a similar dose, expected to translate into a clinically meaningful impact for treating patients with rosacea, and as demonstrated in Emrosi’s Phase 3 clinical trials.
● In September 2024, we presented longer-term data from Checkpoint’s pivotal trial of UNLOXCYT in locally advanced and metastatic cSCC during the European Society for Medical Oncology Congress 2024. The longer-term results for UNLOXCYT demonstrate a deepening of response over time, with higher objective response and complete response rates than initially observed at the primary analyses.
● In May 2024, we announced that the first patient was dosed in a multicenter, placebo-controlled, randomized Phase 2 study of Triplex in patients undergoing liver transplantation. The trial will enroll up to 416 CMV seronegative prospective liver transplant recipients and will be conducted across up to 20 nationally recognized transplant centers in the U.S. The trial is funded by a grant from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health that could provide over $20 million in non-dilutive funding. We believe this data set could ultimately be used to support the approval of Triplex in this setting.

Commercial Product Updates
