Study to Investigate the Efficacy, Safety, and Tolerability of Topical HT-001 for the Treatment of Skin Toxicities Associated With Epidermal Growth Factor Receptor Inhibitors

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Acneiform Eruption Due to Chemical, Xerosis Cutis, Paronychia

In brief

The goal of this clinical trial is to learn about HT-001 Topical Gel for treatment of EGFR inhibitor-induced skin toxicities. The main questions it aims to answer are: * Determine the therapeutic effect of HT-001 for treatment of patients who develop acneiform rash undergoing Epidermal Growth Factor inhibitor (EGFRI) therapy using the acneiform rash investigator's global assessment scale \[ARIGA\] * Evaluate the safety of HT-001 during treatment Participants will apply HT-001 Gel once per day for 6 weeks, during which the effect on treating acneiform rash or other skin disorders induced by EGFRI therapy will be evaluated using different assessment tools to measure severity of rash, pain, and itching (pruritus), as well as the change in quality of life. The study will be completed in 2 periods: the first period is open-label (unblinded) and all patients will receive HT-001 topical gel with the active ingredient; the second period is blinded and patients will be randomized to receive one of three concentrations of HT-001 or placebo. Researchers will compare HT-001 to the placebo in the second period to see if HT-001 provides a significant treatment effect.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Adult participant (ie, ≥ 18 years of age at Screening/Baseline [V1]) prescribed an approved EGFRI to treat cancer (indication within the approved labeling for the EGFRI and/or on National Comprehensive Cancer Network guidelines or equivalent local standards).
• Approved EGFRIs include, but are not limited to: gefitinib, erlotinib, osimertinib, lapatinib, afatinib, dacomitinib, neratinib, vandetanib, lazertinib, cetuximab, panitumumab, necitumumab, pertuzumab, and amivantamab-vmjw.
• Administration of an EGFRI, in combination with other drugs, for treatment of cancer is acceptable as long as the other drug is identified in the approved label of the EGFRI (eg, erlotinib with gemcitabine) or part of the NCCN guidelines or equivalent local standards.
• Participant has developed a rash or symptoms of a rash (papular and/or pustular eruptions or cutaneous burning), as assessed by both Common Terminology Criteria for Adverse Events (CTCAE) grading and ARIGA scales (severity ≤ 3) with overall involvement ≤ 30% BSA.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
• Predicted life expectancy ≥ 3 months.
• Participant is able and willing to comply with contraceptive requirements
• Participant must have the ability and willingness to attend the necessary visits (telehealth and in person).
• Participant must be willing and able to provide written informed consent after the nature of the study has been explained and prior to the commencement of any study procedures.

You may not qualify if…

• Participant has severe cutaneous toxicity (severity = 4 on the CTCAE grading and ARIGA scales) or cutaneous toxicity involvement that is > 30% BSA, or other severe systemic toxicity (severity > 3 on the CTCAE v5.0 scale) as a result of EGFRI therapy.
• Participant has any underlying physical or psychological medical condition that, in the opinion of the Investigator, would make it unlikely that the participant would comply with the protocol or complete the study per protocol.
• Participant has a history of other skin disorders (eg, atopic dermatitis, psoriasis, recurrent skin infections), or history of illness that, in the opinion of the Investigator, would confound results of the study or pose unwarranted risk in administering study drug to the participant.
• Participant has abnormal laboratory values at Screening/Baseline (V1):
• Absolute neutrophil count < 1000/mm3 and WBC count < 3000/mm3
• Platelet count < 50,000/mm3
• Aspartate transaminase (AST) > 2.5 × upper limit of normal (ULN)
• Alanine transaminase (ALT) > 2.5 × ULN
• Bilirubin > 1.5 × ULN
• Creatinine > 1.5 × ULN
• Participant has a known history of QT interval prolongation.
• Participant has a prescribed cancer treatment plan that requires radiation treatment to the head, neck, or upper trunk concurrent with EGFRI therapy or has previously received radiation therapy within 4 weeks prior to Screening/Baseline (V1).
• Participant has received aprepitant or other neurokinin-1 receptor antagonist within 4 weeks prior to Screening/Baseline (V1).
• Participant has had prior treatment with an investigational drug within 4 weeks prior to Screening/Baseline (V1), or at least 8 half-lives of the drug, whichever is longer.
• Participant has an active infection (eg, pneumonia or pneumonitis) or any uncontrolled disease except for the malignancy that, in the opinion of the Investigator, might confound the result or the study or pose unwarranted risk in administering the study drug to the participant.
• Participant has received non-stable escalating doses of topical antibiotics, topical steroids, or other topical treatments within 14 days prior to Screening/Baseline (V1). Participants who have been on stable doses of topical antibiotics, topical steroids, or other topical treatments for 14 days or more are allowed to be enrolled and to stay on their current prescription. Reduction in dose due to improvement in EGFRI-related toxicities is allowed.
• Participant has used non-stable escalating doses of systemic steroids within 14 days prior to Screening/Baseline (V1) excluding low dose systemic corticosteroids as part of standard of care for prevention or treatment of chemotherapy-induced nausea and vomiting; acceptability of the steroid and dose is to be determined by the Investigator. Participants who have been on a stable dose of systemic steroids for 14 days or more are allowed to be enrolled and to stay on their current prescription. Reduction in dose due to improvement in EGFRI related toxicities is allowed. Use of steroid inhalers and nasal corticosteroids is allowed.
• Participant has received non-stable escalating dose treatment with a systemic antibiotic within 14 days prior to Screening/Baseline (V1). Participants who have been on stable doses of systemic antibiotics for 14 days or more are allowed to be enrolled and to stay on their current prescription. Reduction in dose due to improvement in EGFRI-related toxicities is allowed.
• Participant has received concomitant treatment with pimozide, moderate to strong cytochrome p450 (CYP) 3A4 inhibitors (diltiazem, ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir, nelfinavir), or strong CYP3A4 inducers (rifampin, carbamazepine, phenytoin) within 30 days of Screening/Baseline (V1).
• Participant has a history of hypersensitivity to aprepitant or any component of HT-001.
• Participant is pregnant or lactating at Screening/Baseline (V1) or planning to become pregnant (self or partner) at any time during the study, including the follow-up period.
