What is the purpose of this trial?The purpose of this study is to investigate the study drug, OKN4395, administered alone and in combination with pembrolizumab.
The overall objectives of this study are to determine the safety and tolerability (degree to which side effects of a drug can be tolerated) of OKN4395 alone and in combination with pembrolizumab, OKN4395 and metabolites (broken-down substances) of OKN4395 levels in the blood, and antitumor activity of OKN4395 alone and in combination with pembrolizumab.
This study will be split into 2 parts. Part 1a will look at multiple doses of OKN4395 either alone (monotherapy) or with pembrolizumab (combination therapy) administered on day 1 of each 21-day cycle in patients with solid tumors until the participant has disease progression or discontinues for any reason. The dose of OKN4395 will be increased, after each group of 3 or more patients completes their first 3 weeks of treatment and their data is evaluated for safety, with a planned dose range from 10 mg twice a day to 450 mg twice a day through 13 dose levels. Part 1b will evaluate OKN4395 alone and in combination with pembrolizumab administered on day 1 of each 21-day cycle in patients with selected cancer types. Part 1b will comprise 4 cohorts: cohort 1 in sarcoma (OKN4395 alone), cohort 2 in non-small cell lung cancer (NSCLC), cohort 3 in mesothelioma, and cohort 4 in head \& neck squamous cell carcinoma (HNSCC), with cohorts 2 to 4 in combination with pembrolizumab. The monotherapy expansion cohort (Cohort 1) will also be used to choose the optimal dose for further development and to explore the effect of food on the levels of OKN4395 in the blood. The overall study will enrol approximately 166 participants with up to 54 participants to receive OKN4395 alone and 12 participants to receive OKN4395 in combination with pembrolizumab in Part 1a, and 100 participants in Part 1b split: 40 on monotherapy and 60 on combination therapy. The study will be conducted in the US, in the UK and in the EU.
Will I have to stop taking my current medications?The trial protocol does not specify if you must stop taking your current medications. However, certain medications like systemic steroids, NSAIDs, and drugs affecting gastrointestinal pH or specific enzymes must be stopped before starting the trial. It's best to discuss your current medications with the trial team.
What data supports the effectiveness of the drug OKN4395 + Pembrolizumab for solid tumors?Research shows that pembrolizumab, one of the drugs in this treatment, has been effective in treating various cancers like advanced melanoma and non-small-cell lung cancer by helping the immune system attack cancer cells.
12345 Is the combination of OKN4395 and Pembrolizumab safe for humans?Pembrolizumab has been studied in various cancers like ovarian, lung, and bone cancer, showing a safety profile that is generally acceptable, but it can have side effects like fatigue, rash, and diarrhea. However, specific safety data for the combination of OKN4395 and Pembrolizumab is not available in the provided research.
12467 What makes the drug OKN4395 + Pembrolizumab unique for treating solid tumors?This treatment combines OKN4395 with pembrolizumab, an immune checkpoint inhibitor that helps the immune system attack cancer cells. Pembrolizumab is already used for various cancers, but combining it with OKN4395 may enhance its effectiveness, especially in tumors that are less responsive to immunotherapy alone.
