Abstract

Purpose

SJG-136 is a pyrrolobenzodiazepine dimer that forms DNA crosslinks and has demonstrated broad antitumor activity. We undertook this trial to determine the maximum-tolerated dose (MTD), toxicities and pharmacokinetic (PK) profile of SJG-136 in patients with an advanced solid tumor.

Patients and methods

In this phase I study, patients were treated with SJG-136 on days 1, 8 and 15 of a 28-day cycle. Dose levels studied were 10, 20, 40 and 60 μg/m2. PK parameters of SJG-136 were assessed following the intravenous administration of SJG-136 on days 1 and 15 of cycle 1.

Results

Twenty-one patients with advanced solid tumors were treated. Patients had a median of two prior chemotherapy regimens. Fatigue was dose-limiting with SJG-136 60 μg/m2/day administered on days 1, 8 and 15 of a 28-day cycle. Grade 3 thrombocytopenia and delayed onset liver toxicity were seen in one patient each. PK parameters of SJG-136 indicated dose-proportional increases in systemic exposure with increasing doses. No objective responses were seen.

Conclusion

For patients with advanced solid tumors, the MTD of SJG-136 is 40 μg/m2/day administered on days 1, 8 and 15 of a 28-day cycle. The major dose limiting toxicity was fatigue. Alternative dosing strategies are now being evaluated.

Patienten mit metastasiertem hormonsensitivem Prostatakarzinom sollten nicht mehr mit einer alleinigen Androgendeprivationstherapie (ADT) behandelt werden, mahnt ein US-Team nach Sichtung der aktuellen Datenlage. Mit einer Tripeltherapie haben die Betroffenen offenbar die besten Überlebenschancen.

Auch myeloide Immunzellen lassen sich mit chimären Antigenrezeptoren gegen Tumoren ausstatten. Solche CAR-Fresszell-Therapien werden jetzt für solide Tumoren entwickelt. Künftig soll dieser Prozess nicht mehr ex vivo, sondern per mRNA im Körper der Betroffenen erfolgen.
