Specialty pharmaceutical company Hatchtech Pty Ltd today announced
positive results from its two pivotal Phase 3 clinical studies
evaluating Xeglyze™ Lotion (formerly DeOvo Lotion) as a potential
treatment for head lice infestation. Both studies achieved the
pre-defined primary and secondary endpoints and were conducted according
to a Special Protocol Assessment (SPA) agreement with the U.S. Food and
Drug Administration (FDA).
Hatchtech conducted two Phase 3 studies, enrolling a total of 704
subjects across 14 clinical study sites in the United States. The
studies were double-blind, randomized, multi-center, vehicle-controlled,
parallel-group and treated subjects with an active head lice infestation
aged six months and older. The studies were designed to assess the
efficacy, safety and tolerability of a single application of Xeglyze™
Lotion compared to a vehicle lotion, when applied to the scalp and hair
for ten minutes at home. The results were assessed in follow up visits
to the clinical study sites 1, 7 and 14 days following application.
The Phase 3 studies demonstrated that a single, ten minute application
of Xeglyze™ Lotion results in a statistically significant increase in
the proportion of subjects who are cleared of lice compared with the
vehicle lotion. They showed 81.5%1 of patients who received
only one application of Xeglyze™ Lotion and without nit-combing remained
lice free at all follow up visits through to the day 14 visit, which was
the primary efficacy endpoint as agreed with the FDA. The secondary
efficacy endpoint was the proportion of subjects who were lice free at
the Day 1 visit and the Day 7 visit. The studies showed 90% of subjects
were lice free after just one day following treatment with Xeglyze™
Lotion, and 88% were lice free fter 7 days.
Based on research conducted at the University of Melbourne by
Hatchtech's founder Dr Vern Bowles, the active ingredient of Xeglyze™
Lotion, abametapir, was selected in 2005 as a lead compound, targeting
key biological pathways of the lice life cycle, including the lice egg.
Xeglyze™ Lotion is different to other head lice treatments by treating
both eggs and the lice, meaning repeat applications and nit combing are
not required. In addition, Xeglyze™ Lotion has a different mechanism of
action with no known resistance. There is a need for novel treatments
given that head lice have developed resistance to many currently
"The successful eradication of a head lice infestation involves treating
the lice as well as the eggs. Nit combing has traditionally been the
only truly effective way of controlling the eggs and thus reinfestation.
The results of these studies demonstrate that Xeglyze™ Lotion is
effective at eliminating a head lice infestation in 81.5% of subjects,
but most importantly with only one application and without nit combing"
commented, Dr Lydie Hazan, CEO of Axis Clinical Trials in Los Angeles,
and a Principal Investigator on one of the Phase 3 studies. Dr Hazan is
a respected head lice expert and has been involved in the development of
a number of head lice products.
Hatchtech CEO, Hugh Alsop said: "This is a very exciting result,
providing clear evidence in support of the safety and efficacy of
Xeglyze™ Lotion, as well as the superior commercial potential of the
product. Success with these studies now places Hatchtech in a strong
position to seek marketing approval in the US as well as accelerate our
plans for the commercialisation of Xeglyze Lotion. The company remains
on track to file a New Drug Application with the US Food and Drug
Administration in the first half of 2015."
