Cisplatin Plus Bryostatin 1 in Treating Patients With Advanced Cancer

2014-08-27 03:58:52 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of cisplatin plus bryostatin 1 in treating patients who have advanced cancer.

Description

OBJECTIVES: I. Determine the dose limiting toxicity and maximum tolerated dose of combination bryostatin 1 and cisplatin chemotherapy in patients with advanced, incurable solid tumors.

OUTLINE: This is a dose-escalation study. The first 4 cohorts of patients receive an escalating dose of cisplatin with a fixed dose of bryostatin 1, followed by 5 cohorts receiving an escalating dose of bryostatin 1 and a fixed dose of cisplatin. In the first course, cisplatin is given as a 2 hour infusion followed by a 24 hour continuous infusion of bryostatin 1. In all subsequent courses bryostatin 1 is given first and cisplatin afterwards. Treatment continues every 21 days in patients with stable or responding disease. Dose escalation proceeds until the maximum tolerated dose (MTD) of the combination chemotherapy is determined. The MTD is defined as the dose preceding that at which 2 or more patients experience dose limiting toxicity. After the MTD is determined, an additional 10 patients are treated at this dose level. Patients are followed at 1 month.

PROJECTED ACCRUAL: Approximately 24-30 patients will be accrued for this study.

Medical and Biotech [MESH] Definitions

An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.

A solid, unencapsulated tumor of the KIDNEY composed of spindle mesenchymal cells that resemble FIBROBLASTS or muscle cells. The homogeneous mass typically extends into the renal parenchyma and replaces most of the kidney. In most cases, mesoblastic nephroma is benign and occurs in the fetus or newborn, and rarely in the older child or the adult.

A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms.

A malignant cystic or semisolid tumor most often occurring in the ovary. Rarely, one is solid. This tumor may develop from a mucinous cystadenoma, or it may be malignant at the onset. The cysts are lined with tall columnar epithelial cells; in others, the epithelium consists of many layers of cells that have lost normal structure entirely. In the more undifferentiated tumors, one may see sheets and nests of tumor cells that have very little resemblance to the parent structure. (Hughes, Obstetric-Gynecologic Terminology, 1972, p184)

A solid tumor consisting of a dense infiltration of MAST CELLS. It is generally benign.
