A Phase 1 Dose-Escalation Study in Advanced Solid Tumors, Lymphomas or Multiple Myeloma

Phase 1 study to determine safety, tolerability, dose-limiting toxicities (DLTs), and recommended Phase 2 dose of AV-299 administered IV as monotherapy to patients with relapsed or refractory solid tumors, lymphoma, or multiple myeloma. The study will also determine the safety, tolerability and DLTs of AV-299 in combination with erlotinib in patients with relapsed or refractory solid tumors.

Diagnosis and Main Criteria for Inclusion for the Multiple Myeloma Exploratory Cohort Subjects to be Included

* Diagnosis of symptomatic relapsed or refractory multiple myeloma. Note: For relapsed disease, subject must have PD after having achieved at least stable disease for ≥ 1 cycle of treatment to ≥ 1 prior regimen. For refractory disease, subject must have documented evidence of PD during or within 60 days (measured from the end of the last cycle) of completing treatment with the last anti-myeloma drug regimen used just prior to study entry.
