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.
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.
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.
