Gradientech Reports Promising Interim Performance Data Including Cefiderocol for Expanded QuickMIC Gram-Negative Panel
The study, almost halfway completed, includes patient samples from three hospitals and covers six additional antibiotics, including cefiderocol, meropenem-vaborbactam, aztreonam-avibactam, and ceftolozane-tazobactam—key reserve antibiotic treatments for severe infections.
Intermediate results indicate performance exceeding regulatory requirements across all tested antibiotics. Successful validation of cefiderocol would position QuickMIC® as the only automated AST system capable of testing this antibiotic, which is currently limited in clinical use due to complex and non-standardised AST testing methods.
“We are encouraged by the strong interim results, particularly for cefiderocol, and the potential to expand access to testing of critical last-resort antibiotics with QuickMIC®,” says Sara Thorslund, CEO and co-founder of Gradientech.
QuickMIC® is the fastest IVDR approved solution for phenotypic AST directly from positive blood cultures, delivering results in an average of 2–4 hours and enabling early treatment decisions in the critical management of sepsis patients. The evaluation of cefiderocol is conducted in collaboration with Shionogi. Final clinical study results are expected in Q2 2026.
QuickMIC® and its Gram-negative panel are CE marked and commercially available in Europe. QuickMIC is classified as a Breakthrough Device by the U.S. Food and Drug Administration and available for Investigational Use Only in the U.S., but not 510(k) cleared.
