Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Open, multicenter phase I with gradual increase in dosage to evaluate the safety and tolerability of orally administered nintedanib plus letrozole orally (2.5 mg / day) for patients with breast cancer. Nintedanib is administered twice a day orally for 28 consecutive days (Days 1-28) in 4-week cycles.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Phase 0 / I:

At level 1 it includes three patients. If any patient suffers dose limiting toxicity (DLT), it proceeds to the increase in dose to the next level. If 2/3 patients experience DLT, he will close the increased dose and extended / investigate the previous dose level with 3 additional patients.

If the level 2, but less than 1/3 the minimum of 6 patients experience TLD is reached, the phase I be suspended because not expected another rise above Level 2.

Dose levels:

* Level 1: Nintedanib 150 mg twice daily + oral letrozole 2.5 mg / day orally, in a cycle of 28 days.
* Level 2: Nintedanib 200 mg twice daily via oral + letrozole 2.5 mg / day orally, in a cycle of 28 days.
* At least the first cycle will be administered during Phase I. A total of six four-week cycles were administered at the discretion of the investigator.
