Abstract LB-289: A phase I dose escalation study of TKM-080301, a RNAi therapeutic directed against PLK1, in patients with advanced solid tumors.
Notice bibliographique
Résumé
Abstract Background: Polo-like kinase 1 (PLK1) is a serine/threonine kinase that regulates multiple critical aspects of cell progression. PLK1 is over-expressed in many human tumor types and its over-expression is a negative prognostic indicator of patient outcome in a variety of cancers. TKM-080301 is a lipid nanoparticle formulation of a small interfering RNA (siRNA) directed against PLK1 that has been shown to effect highly selective reductions in PLK1 mRNA in vitro and in tumor xenograft models in mice. Methods: A phase I multi-center, open-label, non-randomized, dose-escalation study of TKM-080301 is ongoing in patients with advanced solid tumors or lymphoma. Sequential cohorts of 3 to 6 patients receive TKM-080301 as a 30-minute IV infusion on Days 1, 8, and 15 of a 28-day cycle. Primary objectives include determination of safety, maximum tolerated dose (MTD) and dose limiting toxicities (DLTs). Secondary objectives include characterization of pharmacokinetics (PK) and preliminary assessment of anti-tumor activity and pharmacodynamic effects. Pre-and post-dose biopsy samples are being collected from patients treated after DLT has been established. Results: Twenty-three (23) patients, receiving a cumulative total of 128 doses, have been treated with TKM-080301 at doses ranging from 0.15 to 0.9 mg/kg/week. The most common drug-related adverse events have been mild-to-moderate infusion related reactions with delayed onset, pyrexia, chills, nausea, vomiting, and fatigue. Mild, transient increases in certain cytokines (e.g., IL-6, IL-8, MCP-1) have been observed at dose levels ≤0.75 mg/kg/week and generally correlated with the timing of delayed infusion reactions. DLTs were observed at 0.9 mg/kg/week and included hypoxia/dyspnea in one patient (with a previous history of asthma) and thrombocytopenia in another patient. The dose level was subsequently reduced to 0.75 mg/kg/week. Pharmacokinetic parameters determined after the first dose in Cycles 1 and 2 demonstrated dose proportional Cmax and AUC and no obvious accumulation. Two patients have received TKM-080301 for at least 6 months (6 cycles) with no evidence of cumulative toxicity, including one patient with stable disease (colon) and one patient with a durable confirmed partial response (carcinoid tumor) who has received 8+ cycles of treatment. Conclusions: Preliminary results from this first-in-human trial indicate TKM-080301 was generally well-tolerated by the majority of patients. Preliminary antitumor efficacy has been observed, supporting PLK1 as a therapeutic target. As two DLTs were observed at the dose of 0.9 mg/kg/week, patient accrual is continuing at the 0.75 mg/kg/week dose level. Citation Format: Ramesh K. Ramanathan, Solomon I. Hamburg, Mitesh J.
