A Study to Investigate the Effect of Food on the Bioavailability of Oral Paclitaxel Administered With Encequidar in Participants With Advanced Solid Tumors

The goal of this clinical trial is to learn about the effect of food on absorption of oral Paclitaxel when co- administered with Encequidar tablets in adult patients with tumours. The main questions it aims to answer are: * The effect of food and fasting on absorption of oral paclitaxel when combined with Encequidar tablets * Assessment of safety and tolerability of oral paclitaxel when combined with Encequidar tablets Participants will take Encequidar and oral paclitaxcel with a 1-hour space in between, either after an overnight fast of 10hours or after a meal three days in a row. After 10 days participants that received paclitaxel after fasting will receive the same medicine in the same way after a meal and vice versa. Some participants can elect to take part in the third part of the study which involves taking both paclitaxel and encequidar at the same time after a meal. Participants will \- For parts 1,2 and 3 participants will stay at the clinic from the day before the study starts until day 4 to receive the medicine and participate in checkups and tests. Participants will then visit the clinic on day 6 and 8 for further checkups and tests
