Clinical Trial Summary

The study will evaluate the pharmacokinetics (PK) and safety of a single intravenous (IV) dose of 0.3 mg/kg MB1707 in patients with advanced cancers.


Clinical Trial Description

MB1707, paclitaxel (PTX) conjugated CXC chemokine receptor 4 (CXCR4) peptide antagonist, a peptide-drug conjugate (PDC), for the treatment of cancer. MB1707 is a potent CXCR4 antagonist which inhibits tumor growth and metastasis by blocking the stromal cell derived factor 1 (SDF-1, a.k.a. CXCL12)/CXCR4 signaling pathway. MB1707 contains a conjugated drug, paclitaxel. By specific binding to CXCR4 overexpressed by the tumor cells, MB1707 has a built-in targeted delivery mechanism. The study will evaluate the PK and safety of a single intravenous (IV) dose of 0.3 mg/kg MB1707 in patients with advanced cancers. Up to 6 patients will be enrolled. Patients will be treated with a single intravenous (IV) dose of MB1707 over 3 hours on Day 1 only. Patients will be pre-medicated with an antihistamine (eg, diphenhydramine), a corticosteroid (e.g., dexamethasone), and a H2 receptor antagonist (e.g., famotidine), within 30 to 60 minutes prior to infusion at doses per institutional guidelines. Patients will be observed for 60 minutes after Cycle 1 dose administration. Patients will complete a 14-day Safety Follow-up Visit following the single dose. ;
