Pregnancy
- Pregnant or breast-feeding women will not be entered on this study because there is not yet available information regarding human fetal or teratogenic toxicities. Pregnancy tests must be obtained in females who are post-menarchal.
- Males or females of reproductive potential may not participate unless they have agreed to practice 1 highly effective and 1 additional effective (barrier) method of contraception at the same time during the entire study treatment period and through 3 months after the last dose of study drug, or agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. Patients who themselves or their partners have undergone female or male sterilization do not require 2 methods of contraception. Highly effective methods are defined as those with <1% failure rate with perfect use and include: oral contraceptive pills (combined or progesterone only), intrauterine devices (IUD), hormonal implant or injection, contraceptive patch, and vaginal ring.
Concomitant medications:
- Anti-hypertensives: Patients requiring more than one antihypertensive medication to control blood pressure, or have baseline blood pressure > 95th percentile for age are not eligible (see Appendix VIII).
- Corticosteroids: Patients receiving systemic corticosteroids are not eligible. > 14 days must have elapsed since last systemic corticosteroid. Note: patients using topical or inhaled corticosteroids are eligible.
- Investigational Drugs: Patients currently receiving another investigational drug are not eligible.
- Anti-cancer agents: Patients currently receiving other anti-cancer agents are not eligible.

Patients who require treatment with enzyme inducing anticonvulsants are not eligible (see Appendix III).
- Medications that prolong QTc: Patients who require treatment with medications known to prolong QTc are not eligible

Experimental: Dose Escalation and Expansion
Part 1: This is a study escalating doses (Dose level 1-3) of losartan on a continuous daily dosing schedule and sunitinib (escalating on dose level 4) on a daily dosing with 4 weeks on, 2 weeks off. A cycle of therapy is 6 weeks (42 days).Dosing will be performed based on body surface area (BSA). This portion of the study uses a 3+3 design (i.e. cohort sizes of 3 patients for the first and second cohort at each dose level). Part 2: Once the Maximally Tolerated Dose (MTD) has been determined, 12 patients will enroll to the expansion cohort. These patients will receive the MTD as long as less then 33% of patients experience dose-limiting toxicities. |
Losartan will be administered orally daily on days 1-42 (6 weeks) with dose level assignments per Table 1 of the protocol.
Dosing will be performed based on weight in kilograms and rounded to the nearest 12.5 mg (half of 25 mg tablet).
Dose level 1 dosing will not exceed 50 mg daily and dose levels 2 and 3 dosing will not exceed 100 mg daily.
Doses should be taken at approximately the same time daily and patients should fast for > 4 hours prior to dosing
Sunitinib will be administered orally daily on days 1-28 (4 weeks), followed by 14-day rest period (2 weeks).
Dosing will be performed based on body surface area (BSA) in mg/m2 per Table 1 of the protocol.
Doses should be taken at approximately the same time daily.
