Spero Therapeutics' Phase 3 PIVOT-PO trial for Tebipenem HBr (搜索) has surpassed 60% enrollment as of December 31, 2024, and is on track for completion in the second half of 2025.
The PIVOT-PO trial evaluates Tebipenem HBr (搜索)'s efficacy in treating complicated urinary tract infections (搜索) (cUTI) and acute pyelonephritis (搜索) (AP) in hospitalized adult patients.
Spero Therapeutics reported cash and cash equivalents of $52.9 million as of December 31, 2024, expected to fund operations into mid-2026.
Spero Therapeutics, a clinical-stage biopharmaceutical company, announced that its Phase 3 PIVOT-PO trial evaluating Tebipenem HBr (搜索) for complicated urinary tract infections (搜索) (cUTI) and acute pyelonephritis (搜索) (AP) has reached over 60% enrollment as of December 31, 2024. The company anticipates completing enrollment, targeting approximately 2,648 patients, by the second half of 2025.
The PIVOT-PO trial is a randomized, double-blind study comparing oral Tebipenem HBr (搜索) to intravenous imipenem-cilastatin in hospitalized adult patients with cUTI and AP. The primary endpoint is the overall clinical response at the Test-of-Cure (TOC) visit, assessing both clinical cure and favorable microbiological response. Tebipenem HBr is an investigational oral carbapenem antibiotic. If approved, it would provide an oral alternative to IV antibiotics, addressing unmet medical needs and potentially reducing hospitalizations.
SPR720 and SPR206 Updates
Spero's Phase 2a trial of SPR720 for Non-Tuberculous Mycobacterial-Pulmonary Disease (搜索) (NTM-PD), which enrolled 25 patients, did not meet its primary endpoint based on interim analysis. The company is analyzing the full data to determine the next steps. Furthermore, the FDA has cleared Spero to initiate a Phase 2 trial of SPR206, a next-generation polymyxin, for hospital-acquired or ventilator-associated bacterial pneumonia (搜索) (HABP/VABP), contingent on securing non-dilutive funding.
