Skinject Clinical Development Program SKNJCT-003 & SKNJCT-004 Progress:

The Company is currently conducting a Phase 2 clinical study for SKNJCT-003 in nine (9) clinical sites across the United States. SKNJCT-003, which commenced randomizing patients in August 2024, 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 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 the FDA's 505(b)(2) regulatory pathway to non-invasively treat BCC of the skin using dissolvable D-MNA.

In October 2025, the Company treated its first patient in the 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 with Cleveland Clinic Abu Dhabi (CCAD) as the principal investigator. 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 November 2025, the company received full regulatory and ethical approvals in the United Kingdom to expand its ongoing Phase 2 clinical study (SKNJCT-003) evaluating D-MNA to non-invasively treat BCC of the skin. The approvals were issued by the Medicines and Healthcare products Regulatory Agency (MHRA), the Health Research Authority (HRA) and the Wales Research Ethics Committee (WREC). The MHRA approval followed a comprehensive scientific review of the Investigational Medicinal Product Dossier (IMPD) and protocol. The WREC issued a favorable ethical opinion, and the HRA granted study-wide governance approval, confirming compliance with U.K. Good Clinical Practice and National Health Service capacity and capability standards.

Skinject Platform Expansion:

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, to explore co-development of thermostable infectious disease vaccines.

Pipeline Expansion-Acquisition of Antev

In August 2025, the Company completed the acquisition of Antev Limited ("Antev"), a U.K.-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, 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.

Patient Access & Advocacy-Gorlin Syndrome Alliance Collaboration

In October 2025, the Company announced 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 FDA to allow patients with multiple, recurrent or inoperable BCCs of the skin 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.

About Medicus Pharma Ltd.

Medicus Pharma Ltd. (Nasdaq:MDCX) is a precision-guided biotech/life sciences company focused on accelerating the clinical development programs of novel and potentially disruptive therapeutics assets. The Company is actively engaged in multiple countries, spread over three continents.

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 U.K.-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.

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.

In October 2025, the Company announced 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.
