  • 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.”

  • Dilafor announces patent grant in the U.S. for its Phase II development drug tafoxiparin

    STOCKHOLM, SWEDEN – December 2 , 2016. Dilafor AB, a drug development company focusing on the development of tafoxiparin for obstetric indications, today announced it has been granted a U.S. patent protecting its proprietary compound tafoxiparin.

    Tafoxiparin is in clinical development as a new treatment designed to decrease the incidence of protracted labor both after induction of labor and after spontaneous onset of labor. Protracted labor (i.e labor that lastsmore than 12 hours) 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 12hours.

    The U.S. patent granted by the United States Patent and Trademark Office (USPTO) provides key intellectualproperty protection in the U.S. for Dilafor’s proprietary development compound tafoxiparin until at least April 2033, with the possibility of up to five years’ additional patent term extension. In addition to compound protection, claims have also been granted in the U.S. to a manufacturing method as well as to a number of medical uses of tafoxiparin. Patent applications in a broad range of additional territories including Europe, Asia and Latin America, are pending.

    Lena Degling Wikingsson, CEO of Dilafor, said: “The grant of this U.S. patent is a major milestone for Dilafor and the result of a focused IP strategy within Dilafor to build a comprehensive patent estate around our lead product. The patent will be an essential IP asset for tafoxiparin and its potential use in treating different important obstetrical indications with high unmet medical need.”

    Dilafor recently announced the successful completion of a SEK 51 million financing round, which will enable the company to facilitate a Phase IIb dose finding trial with tafoxiparin in Northern Europe, planned to start before the year end 2016. The study will include women with slow progress of labor after a spontaneous onset.

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 shorten labor time.

    The successful completion of the financing round enables Dilafor to facilitate a Phase IIb dose finding trial with tafoxiparin trial in Northern Europe, which is planned to start before the year end 2016. The study will include women with slow progress of labor after a spontaneous onset.

    Lena Degling Wikingsson, CEO of Dilafor, said: “This planned clinical study is an important event in the clinical development program for tafoxiparin. There is no available treatment today to help these women that have high risk of fetal and maternal complications as a consequence of slow progress and protracted labor. With support of long-term investors, Dilafor has now secured the financial resources needed to reach this next crucial milestone in the development of this promising candidate, and to identify a dose to takeforward into the final stages of clinical development.”

    Jason Chow, CFO of Lee’s Healthcare Industry Fund, said: “"We are delighted to strengthen our partnership with Dilafor by becoming a shareholder as well. Woman Health is one of our focused areas and we look forward to the advancement of Dilafor's lead program Tafoxiparin into the final stages of clinical development."

  • Dilafor announces positive results from a multi dosing safety and pharmacokinetic clinical study.

    STOCKHOLM, SWEDEN – February 5, 2015. Dilafor AB announced today completion of a safety and pharmacokinetic multi dosing phase I study with their lead product tafoxiparin. The purpose of the study was to evaluate different clinical administration routes and different dose levels of tafoxiparin in healthy female volunteers. The results will give guidance on the dosages to be used in the phase II trial in Asia in Labor induction expected to start in end year 2015. Dilafor is a Karolinska Development portfolio company.

The study demonstrated tafoxiparin to be safe and well tolerated and with a predictive pharmacokinetic profile. The outcome of the study will be used in the planning of the global clinical trial program in two major indications; Labor induction and Labor arrest. As a next step and aspart of the clinical development program in Asia together with Lee’s Pharmaceuticals, tafoxiparin will beused in a phase II clinical trial in pregnant women that are induced into labor. Initiation of the study is expected in end of 2015. Decision on the study start is depending on approval from Chinese FDA. Meanwhile during 2015, a phase I clinical safety study is planned in Asian women to support the start of the phase II study and to support the use of Asian clinical data in global clinical development.

    Including this study, tafoxiparin has been used and shown to be safe in totally three clinical trials involving 335 subjects of whom 263 were term pregnant women.

    “This study is an important milestone in the clinical strategy for development of tafoxiparin for obstetricalindications.
