Karen McGuire, CEO and Co-FounderThat stark reality is what drives BioMendics—a biotechnology company with a clear and urgent mission to develop therapies that go beyond symptom management and truly change the course of the disease. At the heart of its work is TolaSure®, a topical gel created using the company’s proprietary MTORX™ liquid crystal platform.
“Unlike existing treatments, which focus on bandaging and soothing wounds, TolaSure® is designed to address the root cause of EBS—mutated keratin proteins that weaken the skin’s structural integrity,” says Karen McGuire, CEO and co-founder.
TolaSure® embodies BioMendics’ commitment to tackling EBS at its source. Formulated on the company’s proprietary MTORX™ liquid crystal platform, this topical gel is designed to reduce both the frequency and severity of blistering by targeting mutant keratin aggregates that compromise the skin’s structure. Easy to apply and non-invasive, it brings hope—particularly to pediatric patients and their families—by offering a practical way to strengthen skin, especially in high-friction areas like the hands and feet.
Yet scientific innovation is only half the story. From the very first human tests, BioMendics set out to create a trial experience founded on empathy and respect. In its Phase I study, every participant received comprehensive support—travel, lodging, and meals were fully covered, and clinic visits were scheduled to minimize disruption to daily life.
One adult volunteer, who had endured severe EBS for years, reported that after using TolaSure®, they were finally able to wear dress boots without pain or blistering—an outcome that had once seemed unimaginable, and one that renewed hope not only for themselves but also for their child living with the same condition. These personal victories are far from exceptions; they are the lifeblood of BioMendics’ mission, as CEO Karen McGuire reflects on a guiding principle shared by many in the EB community: “Because the cost of doing nothing is too great.”
Building on that early success, the team is now preparing for the Phase II TAMES-02 trial, which will enroll participants at Stanford and Northwestern under the leadership of two of the world’s foremost EB experts, Dr. Joyce Teng and Dr. Amy Paller. By combining rigorous scientific methodology with a patient-first ethos, BioMendics continues to push the frontier of what’s possible—working not just to manage symptoms, but to restore strength, dignity, and real change to those living with EBS.

Equally important are the relationships BioMendics has cultivated with patient advocacy organizations such as debra of America, the EB Research Partnership, and community groups like Kisses for EB. Through these partnerships, the company ensures that patient voices inform research priorities, trial design, and long-term planning. Recently, BioMendics was honored with the Partners in Progress Award from debra of America, recognizing its commitment to advocacy and accessibility
Looking ahead, the company sees opportunities well beyond EBS. Its MTORX™ technology holds promise for other rare dermatologic disorders, including epidermolytic ichthyosis and pachyonychia congenita. As its pipeline expands, so does its vision: to lead a new era in dermatology—one where rare skin conditions are no longer a life sentence.
BioMendics is not just developing drugs—it’s working to redefine what’s possible for a group of patients who have waited far too long. Its work reflects not only a belief in the power of medicine but also a deep respect for the people it serves. And in a field where progress can feel painfully slow, BioMendics is moving with purpose—because for patients living with diseases like EBS, every step forward matters.
Deep Dive
Advancing Rare Dermatologic Therapies with Scientific and Clinical Discipline
Rare dermatologic diseases create a very different set of challenges from larger therapeutic markets. Patient populations are small, symptoms are often severe and development programs usually move forward with far less commercial certainty than more common disease areas. For life sciences executives evaluating development-stage therapies or potential partners, the decision cannot rest on scientific novelty alone. The stronger programs are the ones that combine credible biology, practical clinical development and a realistic understanding of what patients and caregivers actually experience day to day.
That balance matters because rare skin disorders are deeply disruptive conditions, not simply cosmetic problems. Patients may live with chronic blistering, pain, infection risk, mobility limitations and ongoing wound care that affects nearly every part of daily life. In many cases, families have also spent years navigating limited treatment options and uncertain clinical progress. As a result, companies entering these areas need to demonstrate not only scientific ambition, but also a development strategy grounded in practical patient benefit.
The most credible therapies tend to focus on the biological mechanisms driving the disease rather than only managing visible symptoms. In rare dermatology, a treatment may appear promising on the surface, but long-term value depends on whether it can meaningfully interrupt the underlying process that causes recurring skin damage. Buyers should look closely at whether the science, formulation strategy and clinical endpoints all connect back to that core biological rationale. Treatments that are easier to apply consistently and better tolerated on fragile or damaged skin also tend to have a more realistic path toward everyday clinical use.
Patient access and trial design are equally important in this field. Rare disease studies often struggle because participation can place a significant burden on patients and caregivers, especially when pediatric populations are involved. Travel demands, frequent site visits, school disruption and physical discomfort can all affect enrollment and retention. Development programs that account for those realities early are generally better positioned to generate meaningful evidence. Collaboration with advocacy groups, experienced clinical investigators and patient-centered trial structures often makes a significant difference in whether studies can move forward efficiently.
For executives assessing rare dermatology programs, evidence strategy ultimately becomes the key differentiator. Small patient populations leave very little room for poorly chosen endpoints, weak study execution or unclear development priorities. The strongest programs usually stay tightly focused on a specific indication and a clearly defined mechanism instead of trying to position themselves too broadly too early. In rare disease development, credibility often comes from disciplined execution more than expansive vision.
BioMendics is developing therapies focused on disorders linked to mutant keratin biology and persistent skin fragility. Its MTORX™ small-molecule liquid crystal platform supports TolaSure Gel, also known as BM-3103, a patented topical therapy currently being studied for epidermolysis bullosa simplex. The company’s ongoing TAMES-02 study includes patients aged four and older and involves collaboration with Stanford Dermatology and Northwestern University Dermatology. The study design also appears structured to reduce unnecessary site-visit burden while focusing on plantar blistering, an area that significantly affects mobility and quality of life for patients. For executives evaluating rare dermatology development programs, BioMendics presents a focused approach that combines mechanism-driven science with practical clinical design and patient-centered trial planning.
