Dilafor initiates Phase 2b clinical trial with tafoxiparin in women planned for labor induction
STOCKHOLM, Sweden – July 9, 2019. Dilafor AB, a drug development company focusing on the development of tafoxiparin for obstetric indications, has enrolled the first subject in its Phase 2b study with tafoxiparin in pregnant women planned for labor induction.
About a quarter of all pregnant women are subject to labor induction. More than half of these inductions fail, which leads to protracted labor that entail an increased risk of complications for both mother and child. In a previous phase 2a study, subcutaneous administration of Dilafor’s drug candidate tafoxiparin has shown a significant positive effect with a shortened time to delivery and an enhanced ripening of the cervix in patients induced into labor.
Dilafor has now enrolled the first subject in a phase 2b study to investigate in a larger group whether treatment with subcutaneously administered tafoxiparin can soften the cervix and improve the outcome of labor induction, and thereby shortening the time to delivery.
The Phase 2b study is a multi-center, double blind, placebo-controlled proof of concept study in term-pregnant first-time mothers with an unripe cervix that are planned for labor induction. The pregnant women will be randomized to either subcutaneous injection of tafoxiparin or placebo once daily up to one week prior to scheduled labor induction. The treatment is then followed by induction according to clinical practice, which is usually balloon catheter or hormonal treatment. The target is to enroll 170 pregnant women in the study that is planned to be performed at delivery clinics in two countries in Europe. Sweden is the first country to be included.
“There is a huge unmet medical need within the obstetric field, and Dilafor’s tafoxiparin has the potential to become a completely new treatment option for pregnant women that have high risk of fetal and maternal complications. That the first patient now is enrolled in the Phase 2b study is an encouraging step in the development of tafoxiparin", comments Lena Degling Wikingsson, CEO of Dilafor AB.

Dilafor presents top line result from a Phase IIb study in tafoxiparin
STOCKHOLM, SWEDEN– November 1, 2018. Dilafor AB, announces today top line results from a Phase IIb study in tafoxiparin. The primary endpoint of the study - reducing time to vaginal delivery, defined as time from start of tafoxiparin treatment until delivery - was not met.
Dilafor today presents results from a Phase IIb‑study in tafoxiparin ‑ a drug candidate that targets the problem of protracted labor in a completely new way compared to treatments available today. In the study, 360 women were randomly divided into one of four treatment arms, either in one of three treatment arms with different doses of tafoxiparin or in a placebo arm. In the active dose groups the women were administered a low, medium or high dose of tafoxiparin in combination with the standard treatment for protracted labor – oxytocin.
Tafoxiparin was well tolerated amongst both women and children, but no statistically significant efficacy was observed in any of the dose levels studied. A full review of the drug candidate’s safety profile will be presented as soon as all patients have completed a follow‑up period.
“The area of protracted labor has for a long time been overlooked – the standard treatment, oxytocin, was introduced already in the 50’s. Even with this setback in the development of tafoxiparin it is important that we continue to work towards reducing the labor‑related complications that arise in connection with protracted labor”, says Gunvor Ekman Ordeberg, CMO and co-founder of Dilafor.
The full results from the study will be published in a scientific journal or at a medical congress at a later stage.

About Dilafor AB
Dilafor AB is a Swedish drug development company focusing on the development of tafoxiparin for obstetric indications. The company’s primary goal is to decrease the incidence of slow progress of labor both after induction of labor and after spontaneous onset of labor. The main owner of Dilafor is KDev Investments AB, which is jointly owned by Karolinska Development AB (publ) and Rosetta Capital IV. The other main owners are The Foundation for Baltic and European Studies (Östersjöstiftelsen) and Praktikerinvest. For more information, please visit: www.dilafor.com.
Tafoxiparin is a proprietary polysaccharide based drug developed by Dilafor. Women that experience protracted and complicated labor have deficiency in a naturally occurring submucosal molecule that plays an important role in labor. Preclinical and clinical data show that tafoxiparin fulfills the role of this molecule and works in conjunction with naturally occurring molecules important in child birth.
Slow progress of labor has an incidence of approximately 40 per cent of all pregnant women and can cause complications both during and after the labor for both the mother and child.
Examples of maternal complications are emergency caesarean sections, postpartum hemorrhages, vaginal tears, anal ruptures and an increased risk of infection in the uterus after the labor. Slow progress of labor creates a tension on the fetus and can cause lower oxygenation of the fetus but also an increased risk of an infection in the child. These complications lead to short and long term consequences for the mother and the newborn in addition to substantial health care costs.
Dilafor initiates phase IIb clinical trial with tafoxiparin in women with slow progress of labor
STOCKHOLM, SWEDEN – January 4 , 2017. Dilafor AB, a drug development company focusing on the development of tafoxiparin for obstetric indications, today announces that the first subject has been enrolled in the Phase IIb study with tafoxiparin in pregnant women who experience slow progress of labor or labor arrest after spontaneous onset.
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 term-pregnant 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.”
Gunvor Ekman-Ordeberg, CMO and co-founder of Dilafor, said: “I am delighted that my 40 years’ preclinical and clinical research within obstetrics have reached this significant milestone. There is a great medical need for new treatments to address protracted labor and I hope that tafoxiparin will make a difference for all these pregnant women.”
