A Phase II, Multicenter, Single-Arm Study of Mipsagargin (G-202) as a Second-Line Therapy Following Sorafenib for Adult Patients with Progressive Advanced Hepatocellular Carcinoma.

: Mipsagargin (G-202) is a thapsigargin-based prodrug with cytotoxic activity masked by a peptide that is cleaved by prostate-specific membrane antigen (PSMA), a protease expressed in prostate cancer cells and the endothelium of tumor vasculature. It was hypothesized that PSMA-mediated activation of mipsagargin would result in disruption of the tumor vasculature, leading to a decrease in blood flow, and in direct cytotoxic effects on tumor cells, resulting in anti-tumor activity. : In this open-label, Phase II study, mipsagargin was administered intravenously on Days 1, 2, and 3 of a 28-day cycle to patients with hepatocellular carcinoma (HCC) who progressed on or after treatment with sorafenib or intolerant of sorafenib.

Molecular mechanisms in cancer: what should clinicians know?

Normal cells are influenced by a variety of environmental and host influences that can produce pro-carcinogenic mutations. Either a single or a series of mutations might result in cellular transformation. Like normal cells, most cancer cells use multiple redundant intracellular signaling pathways to ensure the maintenance and viability of functions critical to their survival.

A phase I/IIA trial of continuous five-day infusion of squalamine lactate (MSI-1256F) plus carboplatin and paclitaxel in patients with advanced non-small cell lung cancer.

Purpose: Squalamine is an antitumor agent that has been shown to have antiangiogenic activity in animal models. This Phase I/IIA study was designed to assess the safety, clinical response, and pharmacokinetics of squalamine when administered as a 5-day continuous infusion in conjunction with standard chemotherapy every 3 weeks in patients with stage IIIB (pleural effusion) or stage IV non-small cell lung cancer.

Experimental Design: Patients with chemotherapy-naive non-small cell lung cancer were treated with escalating doses of squalamine in combination with standard doses of paclitaxel and carboplatin.

Safety and pharmacokinetic effects of TNP-470, an angiogenesis inhibitor, combined with paclitaxel in patients with solid tumors: evidence for activity in non-small-cell lung cancer.

Purpose: Preclinical studies suggested that the antiangiogenic agent TNP-470 was synergistic with cytotoxic therapy. TNP-470 was administered with paclitaxel to adults with solid tumors to define the safety and optimal dose of the combination regimen and to assess pharmacokinetic interactions.

Patients And Methods: Thirty-two patients were enrolled chronologically onto one of two treatment arms.
