Purpose: Matrix metalloproteinases (MMPs) are involved in tumor invasion and metastasis and are over-expressed in Kaposi's sarcoma (KS) cells. The primary aim was to define the safety and toxicity of the MMP inhibitor COL-3 in patients with AIDS-related KS. Secondary aims were to evaluate tumor response, pharmacokinetics, and changes in blood levels of MMP-2, MMP-9, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF).Patients and Methods: COL-3 was administered orally once daily, and doses were escalated in cohorts of three to six subjects. Patients with symptomatic visceral KS or severe tumor-associated edema were excluded. Antiretroviral therapy was permitted but not required. Study end points were grade 3 or 4 toxicity or progressive KS. Serial blood specimens were obtained for pharmacokinetics and levels of MMP-2, MMP-9, VEGF, and bFGF.Results: Eighteen patients received COL-3 in dosing cohorts of 25, 50, and 70 mg/m(2)/d. Prior KS therapy was reported by 17 patients (94%). COL-3-related grade 3 or 4 adverse events were reported by six patients and included photosensitivity, rash, and headache. There was one complete response and seven partial responses, for an overall response rate of 44%, with a median response duration of 25+ weeks. The median COL-3 half-life was 39.3 hours (range, 4.1 to 251.1 hours). There was a significant difference between responders and nonresponders with respect to the change in MMP-2 serum levels from baseline to minimum value on treatment (P = .037).Conclusion: COL-3 administered orally once daily to patients with AIDS-related KS is reasonably well tolerated. The most common adverse event was dose-related photosensitivity. Antitumor activity was noted. Further evaluation of COL-3 for the treatment of KS is warranted.
