Phase I dose-escalation study of F60008, a novel apoptosis inducer, in patients with advanced solid tumours
Abstract
Resistance of cancer cells to cytotoxic therapy can be caused by the activation of strong anti-apoptotic effectors, for example NF-kappaB. Therefore, compounds that inhibit NF-kappaB stimulation might overcome chemotherapy resistance. F60008, a semi-synthetic derivate of triptolide, is converted to triptolide in vivo and activates apoptosis in human tumour cells. We performed a phase I and pharmacological study of F60008 given intravenously as a weekly infusion for 2 weeks every 3 weeks in patients with advanced solid tumours. Twenty patients were enrolled, and a total of 35 cycles were administered. The most frequent haematological side-effect was mild grade 1-2 anaemia. Non-haematological toxicities included fatigue, nausea, vomiting, diarrhoea and constipation, all grade 1-2. Two lethal events were observed in which an increase in caspase-3 activity and overt apoptosis in monocytes and neutrophils could be seen. Pharmacokinetic studies showed high inter-individual variability and rendered F60008 a far from optimal derivate of triptolide.

Due to significant variability among patients and high toxicity in some, F60008 cannot be considered an appropriate derivative of triptolide for cancer patients.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
