Study of Nintedanib Plus Bevacizumab in Advanced Solid Tumors

University of Alabama at Birmingham21 enrolled

Overview

Angiogenesis, the development of new blood vessels, plays an important role in the disease development and tumor growth in many solid organ malignancies. Bevacizumab was the first anti-angiogenic drug to be approved in solid tumors and has shown advantageous activity with multiple tumor types. However, the responses from Bevacizumab are often transient due to the tumor's manipulative abilities to circumvent the usual pathways to find salvage pathways instead. Nintedanib has demonstrated anti-tumor activity in non-squamous non-small cell lung cancer, colorectal cancer, ovarian cancer, and renal cell cancer. The combination of Bevacizumab and Nintedanib are being proposed to target the tumor's manipulation processes to generate alternate pathways for angiogenesis thus creating a potential benefit to delay tumor growth.

This is an open-label, phase I dose-escalation study of Nintedanib combined with standard-dose Bevacizumab for advanced solid tumors in which Bevacizumab has an indication. The primary endpoints will be safety and tolerability of the drug combination and a determination of recommended Phase II dose for Nintedanib in combination with standard dose Bevacizumab. The first three patients will be treated with Nintedanib daily plus Bevacizumab on day one of each three week cycle. If there are no dose limiting toxicities, then three additional patients will be treated with the same drugs with Nintedanib at a slightly higher level. Finally, a third cohort of three patients will be dosed at an even higher level. Once the maximum tolerated dose of Nintedanib is reached, then an additional six patients will be treated at that dose in combination with Bevacizumab until disease progression or unacceptable toxicities.

Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures Exclusion Criteria: 1. Previous therapy with Bevacizumab is allowed, but patient who experienced serious dose-limiting toxicities while on prior Bevacizumab therapy are excluded 2. Prior treatment with Nintedanib (BIBF1120). Known hypersensitivity to Nintedanib, peanut or soya or any other trial drug, their excipients or to contrast media 3.

Radiotherapy to the target lesion within the past 3 months prior to baseline imaging 5. Persistence of clinically relevant therapy related toxicity from previous chemo and/or radiotherapy 6. History of brain involvement with cancer, spinal cord compression, carcinomatous meningitis, or new evidence of brain or leptomeningeal disease. Patients with irradiated or resected brain lesions are permitted provided the lesions are fully treated and inactive, patients are asymptomatic, and no steroids have been used for at least 28 days. 7.
