Dose-Escalation Phase 1 Study of G-202 in Patients With Advanced Solid Tumors

2014-07-23 21:11:00 | BioPortfolio

Summary

This is an open-label, single-arm, dose-escalation Phase I study to determine the maximum tolerated dose (MTD) of G-202 when administered once daily for 3 consecutive days of a 28-day cycle in patients with advanced solid tumors. G-202 will be administered by intravenous infusion over 1 hour on Days 1, 2 and 3 of each 28-day cycle.

Description

Pro-drug chemotherapy is an approach to cancer treatment that is being investigated as a means to achieve higher concentrations of cytotoxic or biologically active agents at a tumor location while avoiding systemic toxicity. With pro-drug chemotherapy, a relatively non-toxic form of a cytotoxin, the pro-drug, is converted into the active cytotoxic agent at the tumor site or other specific location. G-202 is a thapsigargin pro-drug; it consists of a cytotoxic analog of thapsigargin coupled to a masking peptide which inhibits its biologic activity until proteolytic cleavage at the tumor site. Thapsigargin is a natural product with profound effects on cell viability. Thapsigargin is a non-cell-type specific toxin with documented ability to kill a broad spectrum of cancer cell lines as well as normal endothelial cells, fibroblasts and osteoblasts. It induces a rapid and pronounced increase in the concentration of cytosolic calcium, due to blockade of the Sarcoplasmic/Endoplasmic Reticulum Calcium ATPase (SERCA) pump to which it binds with high affinity. The increase in cytosolic calcium leads to induction of apoptosis and ensuing cell death.

The anti-tumor effect of G-202 in humans with advanced solid tumors is not yet known.

Medical and Biotech [MESH] Definitions

An alkylating agent of value against both hematologic malignancies and solid tumors.

An internationally recognized set of published rules used for evaluation of cancer treatment that define when tumors found in cancer patients improve, worsen, or remain stable during treatment. These criteria are based specifically on the response of the tumor(s) to treatment, and not on the overall health status of the patient resulting from treatment.

A smooth, solid or cystic fibroepithelial (FIBROEPITHELIAL NEOPLASMS) tumor, usually found in the OVARIES but can also be found in the adnexal region and the KIDNEYS. It consists of a fibrous stroma with nests of epithelial cells that sometimes resemble the transitional cells lining the urinary bladder. Brenner tumors generally are benign and asymptomatic. Malignant Brenner tumors have been reported.

A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.

B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
