ST1968 Intravenous (Weekly) in Solid Tumors
- Registration Number
- NCT01748019
- Lead Sponsor
- sigma-tau i.f.r. S.p.A.
- Brief Summary
ST1968 is a novel camptothecin derivative which interacts with topoisomerase I-DNA complex, inducing S-Phase specific cytotoxicity. It is endowed with a potent antitumor activity and an increased Therapeutic Index with respect to the clinically used analogues (i.e.irinotecan and topotecan) in some xenograft models (ovary, colon, head \& neck, cervix). Anti-tumor activity has been also noted in platinum resistant ovarian cell xenografts and in topoisomerase I mutant prostate cell lines. The acceptable toxicity profile in animals and the activity in camptothecin-resistant cell lines make ST1968 a good candidate for clinical trials.
- Detailed Description
Multicenter, open label, uncontrolled Phase I pharmacokinetic trial to determine the Maximum Tolerated Dose (MTD) of ST1968 given intravenously (I.V.) once every week for 2 consecutive weeks every 3 weeks and the MTD of ST1968 given I.V. once every 3 weeks. A starting dose of 1.5mg/m2 given as a flat dose of 2.5mg is defined, given once on Day 1, Day 8 every 21 Days (D1, D8 Q21D schedule), over 2 h. Starting dose for the Day 1 every 21 Days (D1 Q21D schedule) has to be determined from the MTD of D1, D8 Q21D schedule.
Plasma, urine pharmacokinetics in all patients (minimum of 3 pts for each cohort) during the first cycle of treatment and in at least 6 patients at the Recommended Dose (RD).
During the study any hints of anti-tumor activity will also be evaluated by RECIST criteria.
