Dose Escalation Study of NKP-1339 to Treat Advanced Solid Tumors

• Composite of pharmacokinetics [ Time Frame: 0, 0.25, 0.5, 1, 2, 4, 6, 10 and 24 hours ] [ Designated as safety issue: No ]
  Plasma and urine samples will be analyzed to determine Cmax, Tmax, AUC, terminal elimination rate, elimination half-life, clearance,and volume of distribution.
• To report any responses to NKP-1339 in subjects with advanced tumors [ Time Frame: >8 weeks ] [ Designated as safety issue: No ]
  Tumor assessments every 2 cycles if patients continue treatment beyond 2 Cycles. Treatment is allowed beyond 2 cycles in patients who achieved at least stable disease, at the discretion of investigator and consent of the patient.
• To explore pharmacodynamic endpoints which may be of use in the further development of NKP-1339 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  Transferrin, transferrin receptor and GRP-78 in plasma.

The purpose of this study is to determine the safety and maximal tolerated dose of NKP-1339, a ruthenium containing compound administered intravenously on a weekly schedule, in patients with advanced solid tumors. The responses to treatment in this population will be evaluated. In addition, the PD and PK properties of the compound will be explored.

NKP-1339 is a novel GRP78 targeted ruthenium based anti-cancer compound which is intravenously administered. GRP78 is a key regulator of misfolded protein processing, which is unregulated in cancer cells. In nonclinical anti-tumor studies, NKP-1339 showed activity against many tumor types, including those resistant to platinum and other standard anti-cancer agents. This Phase I trial evaluates the safety, tolerability, maximum tolerated dose, pharmacokinetics, and pharmacodynamics of NKP-1339.
