Medicus Pharma Ltd. Announces Collaboration with the Gorlin Syndrome Alliance to Pursue Compassionate Use Pathway for Skinject(TM) in Patients with Gorlin Syndrome

Gorlin Syndrome, also known as Nevoid Basal Cell Carcinoma Syndrome, is a rare inherited genetic disorder affecting 1 in 31,000 people worldwide that can develop 500-1000 Basal Cell Carcinoma (BCC) lesions over lifetime

PHILADELPHIA, PENNSYLVANIA / ACCESS Newswire / October 29, 2025 / Medicus Pharma Ltd. (NASDAQ:MDCX) (“Medicus” or the “Company”), a biotech/life sciences company focused on advancing the clinical development programs of novel and potentially disruptive therapeutics assets, is pleased to announce a strategic collaboration with the Gorlin Syndrome Alliance (GSA) to advance compassionate access to SKINJECT™, the Company’s investigational doxorubicin containing microneedle arrays (D-MNA) for patients suffering from Gorlin Syndrome, also known as nevoid basal cell carcinoma syndrome.

Under the collaboration, Medicus and the GSA will jointly pursue the Expanded Access IND Program with the Food and Drug Administration (FDA) to allow patients with multiple, recurrent, or inoperable basal cell carcinomas (BCCs) to access SKINJECT™ under physician-supervised treatment protocols. The initiative aims to establish a framework for expanded access while collecting valuable real-world safety and tolerability data to inform future regulatory filings. It will also more tightly integrate patient community-led insights and data into the design, monitoring, and long-term development of SKINJECT^™ in this rare disease population.

SKINJECT™, is a novel localized immunogenic investigational precision therapy focused on non-melanoma skin diseases, especially basal cell carcinoma (BCC) of the skin.

Gorlin Syndrome is an inherited condition affecting approximately 1 in 31,000 people worldwide. Patients can develop hundreds to over one thousand basal cell carcinomas (BCCs) over their lifetime, often beginning in early childhood. The disease imposes not only a medical but also a physical, emotional and economic toll, requiring frequent scar producing surgeries, topical treatments and lifelong dermatologic care.

“Patients with Gorlin Syndrome endure a lifelong burden of recurring skin cancers that often require repeated surgeries and disfiguring treatments,” said Dr. Raza Bokhari, Executive Chairman & CEO of Medicus. “By working together with the Gorlin Syndrome Alliance, we hope to unite clinical science, regulatory leadership and advocacy to deliver hope for individuals facing lifelong burdens of Gorlin Syndrome, reinforcing our mission to deliver targeted innovation where medical need is greatest.”

“Our families live with a relentless disease, never free, in an endless cycle with cancer. This collaboration may help bridge the gap between breakthroughs in skin cancer therapy and real-world needs faced by Gorlin Syndrome patients,” said Meredith Weiss, GSA Executive Director. “It gives our community a voice in designing pathways to access novel therapies responsibly and ethically. We’re proud to partner with Medicus to explore new therapeutic options that respect the patient voice and accelerate access to innovation.”

Medicus is currently conducting a Phase 2 clinical study for SKNJCT-003 in nine (9) clinical sites across the United States which commenced randomizing patients in August 2024. SKNJCT-003 is a double blinded, placebo controlled triple arm proof of concept Phase 2 clinical study, designed to non-invasively treat basal cell carcinoma (BCC) of the skin using novel, patent protected, dissolvable Doxorubicin-containing microneedle arrays (D-MNA). In March 2025, the Company announced a positively trending interim analysis for SKNJCT-003 demonstrating more than 60% clinical clearance. The interim analysis was conducted after more than 50% of the then-targeted 60 patients in the study were randomized. The findings of the interim analysis are preliminary and may or may not correlate with the findings of the study once completed. In April 2025, the investigational review board approved to increase the number of participants in SKNJCT-003 to ninety (90) subjects. The Company is expanding its trial sites in Europe and has randomized more than 75% of the ninety (90) participants expected to be randomized in the study. In September 2025, the Company received positive feedback from the Food and Drug Administration (FDA) regarding its Type C meeting supporting the development of Skinject, indicating that the Company may follow 505(b)(2) regulatory pathway to non-invasively treat BCC using dissolvable D-MNA.

The Company also has a clinical study (SKNJCT-004) currently underway in the United Arab Emirates (UAE). The study is expected to randomize thirty-six (36) patients in six (6) sites in the UAE. Cleveland Clinic Abu Dhabi (CCAD) is the principal investigator, along with Sheikh Shakbout Medical City (SSMC), Burjeel Medical City (BMC), Rashid Hospital (RH), Clemenceau Medical Center (CMC) and American Hospital of Dubai (AHD). Insights Research Organization and Solutions (IROS), a UAE-based contract research organization, is coordinating the clinical study for the Company. IROS is a M42 portfolio company.

In August 2025, the Company completed the acquisition of Antev, a UK-based late clinical stage biotech company, developing Teverelix, a next generation GnRH antagonist, as a first in market product for cardiovascular high-risk advanced prostate cancer patients and patients with first acute urinary retention relapse (AURr) episodes due to enlarged prostate.

Antev’s flagship drug candidate is Teverelix trifluoroacetate (Teverelix TFA), a long-acting gonadotrophin-releasing hormone (GnRH) antagonist. Unlike GnRH agonists, which can cause an initial surge in testosterone levels, Teverelix directly suppresses sex hormone production without this surge, potentially reducing cardiovascular risks. This mechanism is particularly beneficial for patients with existing cardiovascular conditions. Teverelix is formulated as a microcrystalline suspension, allowing for sustained release and a six-week dosing interval, which may improve patient compliance and outcomes.

SkinJect Inc. a wholly owned subsidiary of Medicus Pharma Ltd., is a development stage, life sciences company focused on commercializing novel, non-invasive treatment for basal cell skin cancer using a patented dissolvable microneedle patch to deliver a chemotherapeutic agent to eradicate tumors cells. The Company completed a phase 1 safety & tolerability study (SKNJCT-001) in March of 2021, which met its primary objective of safety and tolerability; the study also describes the efficacy of the investigational product D-MNA, with six (6) participants experiencing complete response on histological examination of the resected lesion. The Company is currently conducting a randomized, controlled, double-blind, multicenter clinical study (SKNJCT-003) in the United States and Europe. The Company has also commenced a randomized, controlled, double-blind, multicenter clinical study (SKNJCT-004) in the United Arab Emirates.

In August 2025, the Company announced its entry into a non-binding memorandum of understanding (the “MoU”) with Helix Nanotechnologies, Inc. (“HelixNano”), a Boston Based biotech company focused on developing a proprietary advanced mRNA platform, in respect of their shared mutual interest in the development or commercial arrangement contemplated by the MoU. The MoU is non-binding and shall not be construed to obligate either party to proceed with a joint venture or any further development or commercial arrangement, unless and until definitive agreements are executed.

In August 2025, the Company completed the acquisition of Antev, a UK-based late clinical stage biotech company, developing Teverelix, a next generation GnRH antagonist, as a first in market product for cardiovascular high-risk advanced prostate cancer patients and patients with first acute urinary retention relapse (AURr) episodes due to enlarged prostate.

Antev’s flagship drug candidate is Teverelix trifluoroacetate (Teverelix TFA), a long-acting gonadotrophin-releasing hormone (GnRH) antagonist. Unlike GnRH agonists, which can cause an initial surge in testosterone levels, Teverelix directly suppresses sex hormone production without this surge, potentially reducing cardiovascular risks. This mechanism is particularly beneficial for patients with existing cardiovascular conditions. Teverelix is formulated as a microcrystalline suspension, allowing for sustained release and a six-week dosing interval, which may improve patient compliance and outcomes.

In September 2020, Antev completed a Phase 1 clinical trial in which Teverelix was shown to be well tolerated with no dose-limiting toxicities and demonstrated rapid testosterone suppression. The study included 48 healthy male volunteers. In February 2023, Antev also completed a Phase 2a study in fifty (50) patients with advanced prostate cancer (APC), where Teverelix achieved the primary endpoint of greater than 90% probability of castration levels of testosterone suppression (97.5%) but the secondary endpoint of maintaining this rate above 90% was not met with the probability dropping to 82.5% by Day 42.

In January 2023, the FDA, reviewed the Phase 1 and Phase 2a data and provided written guidance on Antev’s proposed Phase 3 trial design for Teverelix. This milestone supports the Company’s clinical plans to develop Teverelix as a treatment for advanced prostate cancer patients with increased cardiovascular risk.

In December 2023, FDA approved the Phase 2b study design in advanced prostate cancer covering 40 patients.

In November 2024, FDA approved the Phase 2b study design in acute urinary retention covering 390 patients.

About the Gorlin Syndrome Alliance: Mission, Registry, and Community Impact

Mission and Role

The Gorlin Syndrome Alliance is a U.S.-based 501(c)(3) nonprofit organization with a stated mission to “thoughtfully support, comprehensively educate, and aggressively seek the best treatments and a cure” for individuals affected by Gorlin syndrome.The GSA serves as a bridge between patients, clinicians, researchers, and industry, offering education, support networks, advocacy, and research infrastructure. It promotes awareness of the syndrome, disseminates patient- and clinician-facing resources (on dermatologic care, surveillance, comorbidity management, etc.), and organizes community engagement events.

Patient Registry & Natural History Efforts

A major pillar of GSA’s research arm is the Gorlin Syndrome Alliance Patient Registry (GSAPR), also called the natural history registry.

The registry is designed to collect standardized, longitudinal data (demographics, genotype, clinical features, treatments, outcomes, quality-of-life) from people with Gorlin syndrome or their caregivers. GSAPR is hosted on a secure platform in collaboration with the National Organization for Rare Disorders (NORD), ensuring data privacy, encryption, and controlled access.

The registry seeks to:

• Illuminate the natural history and disease progression across phenotypes (cutaneous, dental, skeletal, neurologic)

• Serve as a resource for patient identification, clinical trial recruitment, and retrospective analyses of intervention outcomes

• Help harmonize data and standard-of-care practices across clinics and investigators

• Participation in GSAPR is typically open to diagnosed individuals (or caregivers) at no cost to them, with GSA bearing administrative costs of registry maintenance.

• The registry is intended to supersede prior, smaller registries (e.g. CHORI, Stanford, BCCNS registry) to unify the data landscape.

Support, Community, and Outreach

The GSA provides support and connection services including peer networks, education about disease management, and informational resources for patients, families, and clinicians.

The organization encourages grassroots fundraising and awareness campaigns, helping supporters host local or virtual events, distributing educational materials, and promoting visibility of Gorlin syndrome.

GSA also organizes national conferences and scientific meetings to bring together patients, caregivers, clinicians, and researchers.

Contact details: GSA is headquartered at 3005 S. Lamar Blvd, Suite D109 #264, Austin, TX, with phone (267) 689-6443 and email info@gorlinsyndrome.org.
