About this study
Official title: The Efficacy of Topical Timolol Combined With Cryotherapy in EGFR Inhibitor-induced Paronychia - a Double-blinded, Intrapatient Left-to-right Controlled Study
Background: EGFR inhibitors (EGFRi) have been used to treat a wide variety of cancers nowadays. One of the major side effects of EGFRi is paronychia, which was not fatal but may caused huge negative impact on patient's daily activities. Current guidelines regarding EGFRi-induced paronychia suggested treatment with cryotherapy, topical corticosteroid or surgical intervention for Common Terminology Criteria for Adverse Events (CTCAE) grade 2 to grade 3 lesions. Recent studies showed that topical beta-blockers may be effective treatment for EGFRi- induced paronychia. However, the evidence was limited to case series and there was no randomized trials evaluating the efficacy.
Goal: To evaluate whether topical timolol combined with cryotherapy was more effective than cryotherapy alone in treating EGFR inhibitors-induced paronychia.
Method: In this single center, randomized, double-blinded, left-to-right comparison study, we plan to enroll 35 patients with EGFR inhibitors-induced paronychia. Patients eligible to enter this study should be over the age of 20 having at least one finger or toe involved with CTCAE grade 2~3 paronychia on each of their hands or feet. The paronychia should have no indication for surgical treatment. After enrollment, one physician will randomize the hands or feet to either timolol-plus-cryotherapy group or cryotherapy-alone group using a computer-generated random allocation scheme. The side allocated to the timolol-plus-cryotherapy group will receive topical timolol solution twice daily (since the beginning of the allocation and continue for 8 weeks) and topical cryotherapy with liquid nitrogen every other week (at the allocation day, at the 2nd week, 4th week and 6th week after the beginning of the trial). The other side allocated to cryotherapy-alone group will receive placebo (normal saline) twice daily (since the beginning of the allocation and continue for 8 weeks) and topical cryotherapy with liquid nitrogen every other week (at the allocation day, at the 2nd week, 4th week and 6th week after the beginning of the trial). In the treatment phase, patients may receive additional local or systemic antibiotics according to the dermatologist's clinical judgement, but they can not receive topical silver nitrate, trichloroacetic acid or corticosteroid ointment. Patients are evaluated at baseline, at 2, 4, 6 and 8 weeks after the initiation of treatment. Efficacy endpoints include CTCAE grade, scoring system for paronychia related to oncologic treatments (SPOT) and physician global assessment, which are evaluated by a blinded investigator based on digital photos, and pain VAS score and patient global assessment, which are evaluated by questionnaire to the patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Scoring system for paronychia related to oncologic treatments (SPOT)
The SPOT evaluates severity of each hand or foot based on four parameters, including redness, edema, discharge and granulation tissue, each measured on a 4-point scale from 0 to 3 with 0 for no presence of signs and 3 for most severe of lesions. In each parameter, the finger (or toe) with the highest score was selected to be representative of the hand (or foot), and the sum of the four parameters makes the total score of the hand or foot. The highest score of each parameter could originate from different fingers (or toes). The total score of each hand (or foot) ranges from 0 to 12.
Measured: Evaluated at baseline

Primary outcome
Scoring system for paronychia related to oncologic treatments (SPOT)
Time frame: Evaluated at baseline
The SPOT evaluates severity of each hand or foot based on four parameters, including redness, edema, discharge and granulation tissue, each measured on a 4-point scale from 0 to 3 with 0 for no presence of signs and 3 for most severe of lesions. In each parameter, the finger (or toe) with the highest score was selected to be representative of the hand (or foot), and the sum of the four parameters makes the total score of the hand or foot. The highest score of each parameter could originate from different fingers (or toes). The total score of each hand (or foot) ranges from 0 to 12.

The record says: finished, as of the sponsor's last update on 6 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Scoring system for paronychia related to oncologic treatments (SPOT) (time frame: Evaluated at baseline). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05165082, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
