 (submitted: December 14, 2017)
Number of Participants With KB004 Treatment-Related Adverse Events as Assessed using CTCAE v4.0. To determine the maximum tolerated dose (MTD). [ Time Frame: 0-24 months ]
Three patients are recruited per dose level, 3 dose levels. Dose limiting toxicity (DLT) defined as Grade 4 neutropenia > 7 day duration Grade 3 or 4 febrile neutropenia Grade 3 or 4 thrombocytopenia > 7 day duration Grade 4 anaemia > 7 day duration Grade 3 or 4 non-hematologic adverse events which do not resolve within 48 hours with maximal supportive care. Grade 4 or recurrent Grade 3 infusion reactions despite maximal supportive care and dose reductions Significant intracranial haemorrhage not reasonably attributed to other cause More than 14 days of treatment delay due to attributable toxicity Other toxicities as determined by the investigators. In the absence of any dose limiting toxicity in a cohort, escalate to the next dose level. If one DLT is seen in the first three patients of a cohort, an additional three patients will be recruited to that cohort. If two or more DLT's are seen in any cohort, that cohort will be deemed the maximum tolerated dose.

Brief Summary

This is a study of drug KB004 in patients with recurrent glioblastoma (GBM). Eligible patients with measurable tumours will receive an initial trace (5mg) dose of zirconium labelled KB004 (89ZrKB004) on day 1 followed by sequential Positron emission tomography (PET) imaging over 1 week to determine its biodistribution into GBM and normal tissues. Safety assessments and pharmacokinetic (movement of drug) sampling will also be undertaken over this time. On Day 8, patients commence weekly KB004 infusions over 2 hours with standard premedications. Three cohorts are planned in this study (3.5mg/kg, 5.25 mg/kg, 7.9 mg/kg; additional dose levels may be explored based on toxicity, efficacy and biodistribution data as determined by the safety monitoring committee). On day 36, patients receive both 89ZrKB004 and KB004, allowing assessment of receptor occupancy to guide recommended phase two dose (RPTD) determination. Response rate (RANO) and survival data will be collected and patients benefiting may continue KB004 treatment until disease progression. Primary objective: to determine the toxicity and recommended phase two dose (RPTD) of KB004 in patients with advanced Glioblastoma (GBM).

Secondary objectives: to determine the biodistribution and pharmacokinetics of 89ZrKB004; to determine frequency of EphA3 (ephrin receptor A3) positive glioblastoma in archival specimens and by 89ZrKB004 scans, and correlate with known biomarkers; to describe response rates per RANO criteria (Response Assessment in Neuro-Oncology Criteria) and pharmacodynamics following KB004 infusion; Exploratory objectives: to perform exploratory analysis between clinical outcomes and biodistribution/Pharmacokinetics (PK)/pharmacodynamics (PD) data, including from matched biopsies.

Study Arms  ICMJE Experimental: KB004 dose escalation
Patients will be entered at each KB004 dose level sequentially until 3-6 patients are evaluable for safety. Three sequential cohorts are planned in this study (3.5mg/kg, 5.25 mg/kg, 7.9 mg/kg) Additional dose levels may be explored based on the emerging data in the study.
