Hoth Therapeutics advances HT-001 as promising therapy for EGFR inhibitor-related skin toxicities

Hoth Therapeutics, Inc. has announced positive findings for HT-001 treatment, positioning it as a potential breakthrough therapy for EGFR inhibitor eruptions, a common and often painful side effect experienced by cancer patients undergoing targeted therapy. The data is set to be presented at the American Academy of Dermatology (AAD) 2025 Annual Meeting, running from March 7-11, 2025. The Hoth Therapeutics findings highlight HT-001’s ability to address EGFR inhibitor eruptions, a dermatologic condition that can significantly affect patient quality of life and, in severe cases, lead to modifications in cancer treatment.

What Are EGFR Inhibitor-Associated Skin Reactions?

Epidermal Growth Factor Receptor (EGFR) inhibitors are widely used in oncology to block the EGFR pathway, which is responsible for cancer cell proliferation and survival. While these therapies have significantly improved outcomes for patients with lung, colorectal, and breast cancers, they are also known to cause EGFR inhibitor eruptions, characterized by painful papulopustular rashes, inflammation, and itching. These reactions typically appear within weeks of starting therapy and can persist throughout treatment, often requiring dose adjustments or discontinuation.

How Effective Is HT-001 in Treating EGFR Inhibitor Eruptions?

A recent case study presented by Hoth Therapeutics findings demonstrated the efficacy of HT-001 treatment in a 59-year-old patient with metastatic breast cancer who developed EGFR inhibitor eruptions while undergoing treatment with paclitaxel, trastuzumab, and pertuzumab. The patient experienced pruritic, burning red papules on the face, scalp, and upper back—common areas affected by EGFR inhibitor-related dermatologic toxicity.

After just one week of applying HT-001 treatment twice daily, the patient experienced full symptom resolution, with no recurrence in the following three weeks. These findings indicate that HT-001 may offer a rapid and effective treatment for EGFR inhibitor eruptions, addressing a major gap in supportive care for cancer patients.

How Does HT-001 Work in Reducing Skin Inflammation?

HT-001 is a topical neurokinin 1 receptor (NK1R) antagonist designed to mitigate EGFR inhibitor eruptions by blocking the inflammatory effects of the Substance P (SP)-NK1R pathway. This pathway plays a critical role in neurogenic inflammation, which is a major factor in the development of EGFR inhibitor eruptions. By targeting NK1 receptors, HT-001 treatment helps reduce inflammation, redness, and itching while promoting skin healing.

Preclinical research has also suggested that HT-001 treatment may help prevent hair loss associated with EGFR inhibitor eruptions, a secondary but distressing side effect for many patients undergoing cancer therapy. By addressing multiple dermatologic concerns linked to EGFR inhibitors, HT-001 presents a comprehensive approach to managing treatment-related skin toxicities.

Why Is There an Urgent Need for Effective Treatments for EGFR Inhibitor Eruptions?

With up to 90% of patients on EGFR inhibitors experiencing EGFR inhibitor eruptions, there is a critical demand for targeted therapies that can provide relief without interfering with cancer treatment. Current treatment approaches, such as topical corticosteroids, antibiotics, and oral antihistamines, often provide limited relief and may not fully address the underlying inflammatory mechanisms.

Severe EGFR inhibitor eruptions can lead to pain, discomfort, and infections, sometimes forcing oncologists to lower the dosage of cancer therapy or switch treatment regimens. By providing an effective and well-tolerated solution, HT-001 treatment could enable patients to continue lifesaving EGFR-targeted therapies without unnecessary disruptions.

What Are the Next Steps in Clinical Trials for HT-001?

Following the encouraging Hoth Therapeutics findings, the company is currently conducting a Phase 2A clinical trial to assess the safety and efficacy of HT-001 treatment in a larger patient population. The trial will evaluate the treatment’s impact on varying severities of EGFR inhibitor eruptions, exploring whether its anti-inflammatory properties extend to other dermatologic toxicities caused by targeted cancer therapies.

If successful, HT-001 treatment could become the first FDA-approved therapy specifically designed to manage EGFR inhibitor eruptions, addressing an unmet medical need in oncology. By providing a non-invasive, patient-friendly treatment, HT-001 could become an essential part of supportive cancer care.

How Does HT-001 Fit into Hoth Therapeutics’ Broader Research Efforts?

In addition to its research on HT-001 treatment, Hoth Therapeutics findings have also highlighted promising developments in obesity management. The company has been investigating Glial Cell Line-Derived Neurotrophic Factor (GDNF) as a potential treatment for obesity, with preclinical research suggesting that GDNF could enhance metabolism, reduce fat accumulation, and improve insulin sensitivity.

By pursuing innovative, first-in-class therapies, Hoth Therapeutics is positioning itself as a leader in dermatologic and metabolic research, developing treatments that could significantly impact both cancer patients and individuals managing metabolic disorders. The company’s expanding research pipeline reflects a strategic focus on addressing high-impact medical challenges through targeted drug development.

What Could HT-001 Mean for the Future of Cancer Supportive Care?

As cancer treatments become increasingly targeted, EGFR inhibitor eruptions and other side effects will continue to be a key concern for oncologists and patients alike. The Hoth Therapeutics findings suggest that HT-001 treatment could provide a safe, effective, and non-steroidal alternative to current supportive therapies, offering relief to patients without compromising the effectiveness of their cancer treatment.

If ongoing clinical trials confirm the drug’s efficacy, HT-001 treatment could represent a paradigm shift in how EGFR inhibitor eruptions are managed. Instead of relying on broad-spectrum anti-inflammatory treatments, oncologists could have a targeted dermatologic therapy specifically designed to counteract the effects of EGFR inhibitors, ensuring patients can continue their cancer treatments with minimal discomfort.

With a growing focus on patient quality of life, the development of HT-001 treatment aligns with the broader movement toward precision medicine in oncology, where treatments are tailored not only to target cancer cells but also to support patients’ overall well-being.
