The aim of part 1 of this study is to determine the optimal biological dose (OBD) and maximum tolerated dose (MTD) for WX-554 and the recommended dose/dose schedules for the chronic treatment in part 2. The aim of part 2 is to further determine the safety and tolerability of chronic treatment with WX-554.

Condition Intervention Phase
Advanced Solid Tumours Drug: WX-554 Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase I/II, Open-label, Dose-escalation Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics and Clinical Activity of the MEK Inhibitor WX-554 in Patients With Solid Tumours

Further study details as provided by Wilex:

Primary Outcome Measures:
  • Part 1: Determination of the Optimal Biological Dose (OBD) by the assessment of ERK phosphorylation (pERK) in peripheral blood mononuclear cells (PBMC) and assessment of TNF-alpha in plasma. [ Time Frame: Cycle 1 (21 days) ]
  • Part 1: Determination of the Maximum Tolerated Dose (MTD) for WX-554 by the evaluation of DLTs in 3-6 patients at the end of 1 treatment cycle [ Time Frame: Cycle 1 (21 days) ]
  • Part 2: To further determine the safety and tolerability by evaluating the incidence and severity of adverse events and serious adverse events (as per CTCAE grading), changes in hematology and chemistry values, vital signs, ECGs. [ Time Frame: expected average of 3-6 months ]

Secondary Outcome Measures:
  • Assessment of PK variables maximum observed concentration (Cmax), minimum observed concentration (Cmin), time at which Cmax was present (tmax), Area Under Curve (AUC) [ Time Frame: PK profile on day 1 and day 8 ]
  • Assessment of ERK phosphorylation (pERK) in PBMC and tissue, assessment of TNF-alpha in plasma after oral intake of the OBD/MTD. [ Time Frame: expected average of 3-6 months ]
  • Tumour response evaluation using RECIST 1.1 [ Time Frame: expected average of 3-6 months ]
