Phase 1 Trial of Bi-shRNA STMN1 BIV in Refractory Cancer.

ABSTRACT: Stathmin1 (STMN1) is a microtubule modulator that is expressed in multiple cancers and correlates with poor survival. We previously demonstrated in vivo safety of bifunctional (bi) shRNA STMN1 bilamellar invaginated vesicle (BIV) and that systemic delivery correlated with antitumor activity. Patients with superficial advanced refractory cancer with no other standard options were entered into trial. Study design involved dose escalation (four patients/cohort) using a modified Fibonacci schema starting at 0.7 mg DNA administered via single intratumoral injection. Biopsy at baseline, 24/48 hours and resection 8 days after injection provided tissue for determination of cleavage product using next-generation sequencing (NGS) and reverse transcription quantitative polymerase chain reaction (RT-q
