This phase I/II trial studies the side effects and best dose of a hydroxychloroquine, nelfinavir, sirolimus, metformin, and dasatinib combination (COAST) and how well it works at treating patients with prostate cancer that has spread to other parts of the body (advanced) or that has come back (recurrent) and other advanced cancers. Autophagy is a cancer cell survival mechanism that is involved in cancer growth, treatment resistance, and spreading (metastasis). Hydroxychloroquine and nelfinavir inhibit the process of autophagy. Metformin, dasatinib, and sirolimus all stress autophagy. This clinical trial tests the safety, side effects, and best dose of giving these drugs in combination for the treatment of prostate and other advanced cancers.

PRIMARY OBJECTIVES:
I. To define the recommended phase 2 dose (RP2D) of the COAST combination. (Phase I)
II. To evaluate the anti-tumor activity of the COAST RP2D combination in patients with advanced prostate cancer. (Phase II)
SECONDARY OBJECTIVES:
I. To evaluate the anti-tumor activity of the COAST combination in cancer patients with advanced disease based on: objective response rate (ORR), disease control rate (DCR), duration of response (DOR), best overall response (BOR), progression-free survival (PFS) and overall survival (OS). (Phase I)
II. To assess changes in relevant biomarkers (prostate specific antigen [PSA], carcinoembryonic antigen [CEA], CA125) during COAST therapy. (Phase I)
III. To evaluate change in quality of life (QOL) (Functional Assessment of Cancer Therapy [FACT] instruments) in patients with advanced cancer treated with COAST therapy. (Phase I)
IV. To assess the safety of the COAST RP2D in patients with advanced prostate cancer. (Phase II)
V. To evaluate the anti-tumor activity of the COAST RP2D based on: DCR, DOR, BOR, PFS and OS. (Phase II)
VI. To assess changes in relevant biomarkers (PSA, CEA, CA125) during COAST therapy at the RP2D. (Phase II)
VII. To document the change in QOL (FACT instruments) in patients treated with COAST at the RP2D. (Phase II)
OUTLINE: This is a phase I, dose-escalation study of metformin and nelfinavir followed by a phase II study.
ARM I: Patients receive hydroxychloroquine orally (PO) twice daily (BID) and sirolimus PO once daily (QD) and metformin PO QD beginning on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive hydroxychloroquine PO BID and sirolimus PO QD, metformin PO QD, and dasatinib PO QD beginning on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM III: Patients receive hydroxychloroquine PO BID and nelfinavir PO BID and sirolimus PO QD and metformin PO QD beginning on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM IV: Patients receive hydroxychloroquine PO BID and nelfinavir PO BID and sirolimus PO QD, metformin PO QD, and dasatinib PO QD beginning on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up with after 30-42 days.
