SPI-1005 for Prevention and Treatment of Tobramycin Induced Ototoxicity

Summary

The primary objective of this study is to determine the safety and efficacy of SPI-1005 treatment in CF patients with active pulmonary exacerbation that are receiving an IV course of tobramycin, determined by comparing hearing assessments, spirometry, Pharmacokinetic (PK), Physical Exam, Adverse Events (AEs) and Labs baseline to post-treatment. The secondary objectives of this study are to determine Pharmacogenomics and Pharmacodynamics of SPI-1005.
