Trial overview
NCT04674683 is an interventional Phase 3 study in people with metastatic or unresectable melanoma.[1] The trial status is Authorised, and the planned enrollment is 325 participants.[1]
This study is looking at Tucidinostat as part of a treatment plan for a serious form of skin cancer.[1] The trial is focused on whether the study treatment can improve progression-free survival, which means the time before the cancer gets worse or the patient dies.[1]
Who can participate
The trial is for patients with metastatic melanoma or unresectable melanoma.[1] Metastatic means the cancer has spread to other parts of the body, and unresectable means it cannot be removed with surgery.[1]
The source data does not list other eligibility details, such as age limits, test results, or previous treatments.[1]
Treatments being tested
The study compares two treatment arms.[1] The test arm uses Tucidinostat with nivolumab, and the control arm uses placebo with nivolumab.[1]
In the trial record, nivolumab is listed as OPDIVO 10 mg/mL concentrate for solution for infusion, given by infusion, while Tucidinostat is listed as an oral drug.[1] The study summary also describes the comparison as HBI-8000 plus nivolumab versus placebo plus nivolumab.[1]
Study phase and design
This is a randomized study, which means participants are assigned to a treatment group by chance.[1] Randomization helps make the two groups more similar so the results are easier to compare.[1]
The trial is in Phase 3, which usually means the treatment is being tested in a larger group and compared against another treatment or placebo.[1] In this study, the comparison is against placebo plus nivolumab.[1]
Outcomes being measured
The primary endpoint is progression-free survival (PFS).[1] PFS is defined as the time from randomization to the first documented disease progression, or death from any cause, whichever happens first.[1]
Disease progression is assessed using RECIST 1.1, a standard way to measure whether tumors have grown, shrunk, or stayed the same.[1] The progression event is determined by BIRC, an independent review group that checks the study results in a neutral way.[1]
What this means for patients
For patients, this trial is testing whether adding Tucidinostat to nivolumab may help keep metastatic or unresectable melanoma from getting worse for longer.[1] The main result the researchers will watch is how long people stay free from progression or death.[1]
Because the study is in Phase 3 and includes 325 participants, it is designed to give a more reliable comparison between the study treatment and the control treatment.[1] The trial record provided does not include other outcomes beyond PFS.[1]
