With the exception of Bevacizumab treatment, which must be completed 30 days prior to registration for protocol therapy.
Prior radiation therapy to < 25% of the bone marrow [see bone marrow radiation chart in the study procedure manual (SPM)] allowed if completed within 30 days prior to registration for protocol therapy.

No clinically significant infections as judged by the treating investigator.
No liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis.
No collecting duct, medullary or sarcomatoid histology.
No prior treatment with temsirolimus or everolimus in the phase II component of the study. NOTE: Prior treatment with these agents is permitted in the phase I component of the study.
No use of full dose, therapeutic anti-coagulation with warfarin or related anti-coagulants or unfractionated or low molecular weight heparins.
No uncontrolled hypertension (BP >150/100mmHg despite full doses of 1 anti-hypertensive medication).

Phase II: 6-month Progression Free Survival (PFS) With the Addition of BNC105P to Everolimus.

Improvement in 6-month PFS with the addition of BNC105P to everolimus. Progression is defined using RECIST criteria as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions

Phase I: Response Rate of BNC105P in Combination With Everolimus.

Number of objective responses per RECIST criteria. Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD. Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
