<qa>  How many patients will be treated at a higher level?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.
