Gedea Biotech, has reported results from a clinical study of its lead product, pHyph, a vaginal tablet for topical treatment of bacterial vaginosis (BV).
In this open-label, single-armed, multi-center study, 82% of the women were clinically cured after 7 days. The cure rate corresponds to existing antibiotic-based treatment. Gedea wishes to caution however, that whilst these results are highly promising, further studies are needed to confirm results.
“These results for pHyph are indeed highly promising, showing effectiveness equivalent to antibiotics in treating bacterial vaginosis. The cure rate and recurrence numbers gives us strong confidence to continue our pHyph program and to confirm the results in upcoming studies,” says Annette Säfholm, Gedea Biotech’s CEO.
Larger studies including recurrence data are being planned.
The vaginal tablet, pHyph acts by restoring the patient’s pH to its normal level of pH 4,0 – 4,5 which is optimal for the protective lactobacilli pHyph also breaks down the biofilm formed during bacterial vaginosis in which the infectious bacteria begin to thrive. The naturally occurring active ingredient GDA 001 in pHyph has a well-documented safety profile and is already approved as a food additive.
The pHyph study enrolled a total of 24 patients each of whom met at least three of the four Amsel criteria – a thin white yellow homogeneous discharge; clue cells on microscopy; a pH of vaginal fluid > 4.5 and release of a fishy odour on adding alkali. Patients were treated with pHyph for one week and primary endpoints were the clinical cure rate at Day 7 as well as safety and tolerability data. Patients were aged 18-49 and the median age was 33. In the Full Analysis Set (FAS, n=22) a total of 18 women (82%) were clinically cured, as defined by the absence of all the three Amsel criteria. Recurrence numbers at day 35 were found to be very low.
“Bacterial vaginosis is a common problem, and current remedies such as antibiotics are not always effective. There is need for new, effective treatments not involving antibiotics. The results of this study are promising and may lead to a much-needed treatment alternative,” says Monika Cardell, MD and senior consultant in obstetrics and gynecology at Skåne University Hospital, Lund. Monika Cardell was also the Principal Investigator of the clinical trial.
