Karolinska Development portfolio company Dilafor initiates Phase IIb clinical trial with tafoxiparin in women with protracted labor
STOCKHOLM – January 4, 2017. Karolinska Development AB (Nasdaq Stockholm: KDEV) today announces that its portfolio company Dilafor AB, a drug development company focusing on the development of tafoxiparin for obstetric indications, has enrolled the first subject in its Phase IIb study with tafoxiparin in pregnant women who experience slow progress of labor or labor arrest after spontaneous onset.
Details from the Dilafor press release follow:
Tafoxiparin is in clinical development as a new treatment designed to decrease the incidence of
protracted labor (i.e labor that lasts more than 12 hours), which is the main cause of emergency
surgical deliveries such as caesarian section. The condition is often associated with complications for
both mother and child. Tafoxiparin has shown in a Phase II clinical trial encouraging evidence that it
can decrease the proportion of women with labor more than 12 hours.
The Phase IIb study is a multi-center, double blind, placebo-controlled dose-finding study in termpregnant
first-time mothers that after spontaneous onset of labor require labor augmentation due
to primary slow progress or labor arrest. The pregnant women will be randomized to receive one of
three different dosages of tafoxiparin or placebo. The treatment will be as an adjunct to standard of
care, which is intravenous infusion of oxytocin. The target is to enroll 360 pregnant women in the
Phase IIb study.
This proof of concept study is designed to demonstrate reduced time to vaginal delivery defined as
time from start of tafoxiparin treatment until delivery. Secondary endpoints include safety,
proportion of women with labor time more than 12 hours, number of women with instrumental
deliveries such as vacuum extraction and number of caesarian sections. The study is planned to be
performed in two countries in Europe including up to 14 delivery clinics. Sweden is the first country
to be included.
Lena Degling Wikingsson, CEO of Dilafor, said: “We are excited to initiate this proof of concept study
with tafoxiparin in this important indication. The only option for pregnant women who experience
protracted labor and do not respond to current clinical practice is acute caesarian sections, which
are often associated with complications for both mother and child. We have already seen
encouraging results in a completed clinical study with tafoxiparin and look forward to the results of
this new trial, which if positive, will pave the way for a pivotal trial and potentially a new treatment
option for patients.”
Viktor Drvota, Chief Investment Officer of Karolinska Development, adds: “Dilafor’s progress over
the last 12 months has been really positive. The Company recently completed a financing round to
support it through to its next value inflection point; and having recently been granted a U.S. patent
for tafoxiparin, the start of Dilafor’s Phase IIb study is yet another important development for the

Tafoxiparin is a heparan sulphate mimetic, a proprietary polysaccharide based drug developed by
Dilafor. Women that experience protracted and complicated labor have deficiency in heparan
sulphate which is a naturally occurring polysaccharide and plays an important role in labor.
Preclinical and clinical data show that tafoxiparin fulfills the role of heparan sulphate and works in
conjunction with naturally occurring molecules important in child birth. Slow progress of labor has
an incidence of approximately 40% of all pregnant women. It is associated with a number of both
long and short term maternal and fetal complications such as emergency caesarean sections,
postpartum hemorrhages, vaginal tears, anal ruptures, meconium-stained amniotic fluid and
asphyxia. These complications lead to short and long term consequences for the mother and the
newborn in addition to substantial health care costs.
