In Message 20932102 , MJ says, "My memory on 2103 PK is going back to 2000/2001. It was one report-note (I found it online), but now I can not find even print copy ... Never saw complete PK data (urine content). ...".

He also provides links to PH 1 study abstracts which seem to disagree with his memory.

In the first abstract posted is the statement, "Peak concentrations of unconjugated paclitaxel in plasma varied from 0.06 to 2.48µM, but were less than the threshold concentration for toxicity of 0.1µM 24 hours after CT-2103 administration at doses up to 480mg/m2. The patient at 720mg/m2 who experienced Grade 4 toxicity had prolonged elevated plasma concentrations of paclitaxel (0.53µM at 24 hr) and remained above 0.1µM for over 48 hours.".

Is this inconsistent with the drug being active in tumours?
