Two Phase 2b clinical trials led by LMU University Hospital Munich demonstrated that sutezolid and delpazolid, both oxazolidinone antibiotics, offer safer alternatives to linezolid for tuberculosis treatment with no cases of nerve damage or blood toxicity observed.
The SUDOCU and DECODE trials, conducted in South Africa and Tanzania, tested these drugs in combination with bedaquiline, delamanid, and moxifloxacin, marking the first studies to evaluate these specific four-drug combinations.
Delpazolid at 1200 mg once daily achieved optimal drug levels and was well tolerated over 16 weeks, while sutezolid showed strong antibacterial activity across all tested doses.
The findings, published in The Lancet Infectious Diseases, address the urgent need for safer TB treatments as linezolid's prolonged use frequently causes serious adverse events including anemia and optical neuropathy.
