Advanced Solid Tumors With and Without Brain Metastases
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
|Official Title:||A Phase 1, Open-Label, Dose Escalation Study of ANG1005 in Patients With Advanced Solid Tumors and Metastatic Brain Cancer|
- To characterize the safety and tolerability of intravenously administered ANG1005 in patients with advanced solid tumors and metastatic brain cancer. [ Time Frame: On-going ]
- To identify the maximum tolerated dose (MTD) of ANG1005 in patients with advanced solid tumors and metastatic brain cancer. [ Time Frame: End of dose escalation ]
- To examine the pharmacokinetics (PK) of ANG1005. [ Time Frame: End of study ]
- To confirm the safety and tolerability of ANG1005 at the MTD. [ Time Frame: End of dose escalation ]
- To assess the immunogenicity of ANG1005. [ Time Frame: End of study ]
- To obtain preliminary information on the antitumor activity of ANG1005 in patients with advanced solid tumors with brain metastases. [ Time Frame: On-going ]

This is a phase 1, multi-centre, sequential cohort, open-label, dose-escalation study of the safety, tolerability, and PK of ANG1005 in patients with solid tumors (with or without brain metastases). ANG1005 will be given by IV infusion once every 21 days (1 treatment cycle). Each patient will participate in only 1 dose group and will receive up to 6 cycles. Patients may receive additional cycles of ANG1005 if there is no evidence of tumor progression, there is recovery to ≤Grade 1 or baseline nonhematologic, ANG1005-related toxicity (except alopecia), the absolute neutrophil count is ≥1.5 x 109/L, and the platelet count is ≥100 x 109/L.
Initially, cohorts of 1 - 3 patients will be enrolled into each dose group. Dose escalation by dose doubling will be done for the first 3 dose groups followed by a modified Fibonacci dose escalation scheme with increases of 67%, 50%, 40% and 33% thereafter. If 1 or more patients in a cohort experience an emergent ≥ Grade 2 drug-related toxicity during the first treatment cycle, then a minimum of 3 patients will be enrolled into that, and all subsequent cohort(s) and dose doubling will be stopped if applicable.
If > 1 patient in a cohort experience a dose limiting toxicity (DLT) during the first treatment cycle, defined as any of the following that are both treatment-emergent and at least possibly related to ANG1005: i) Any Grade 3 or 4 nonhematologic toxicity, ii) Febrile neutropenia, iii) Grade 4 neutropenia of ≥7 days duration, and/or iv) Any Grade 4 thrombocytopenia, then dose escalation will stop and prior doses will be explored as the maximum tolerated dose (MTD), that dose-level at which ≤1 of 6 patients in a cohort develop an emergent DLT).
Once the MTD is established, approximately 14 patients will be enrolled at that dose-level in order to further assess the safety and tolerability of ANG1005, the PK profile of ANG1005 at the MTD, and the preliminary anti-tumor activity of ANG1005 in patients with solid tumors (with or without brain metastases).
