Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 to 36 years
  • Women only
  • Adult

Who may be able to join

  • Pre-menopausal woman aged 21 to 36 years, inclusive, at time of consent
  • Infertile woman who justified IVF-ET or ICSI-ET treatment and who wished to conceive
  • A history of at least three ART cycles resulting in a transfer of at least two apparently healthy embryos and no evidence of implantation menstruation and/or beta hCG < 10 IU/L at the end of the cycle)
  • Had regular ovulatory spontaneous menstrual cycles lasting 25 to 35 days

Show all 15Show fewer
  • A body mass index (BMI) of ³ 20 and £ 30 kg/m2, calculated according to the following formula: BMI (kg/m2) = Body Weight (kg) / Height * Height (m2)
  • The presence of both ovaries
  • A uterine cavity without abnormalities which, in the investigator's opinion, could impair embryo implantation or pregnancy outcome, as assessed by ultrasound (US) examination performed within six months prior to beginning GnRH-agonist therapy
  • Normal cervical cytology within three years prior to beginning GnRH- agonist therapy.
  • At least one wash-out cycle (defined as ³ 30 days since the last dose of clomiphene citrate or gonadotrophin treatment) since the last ART cycle and/or clomiphene citrate or gonadotrophin treatment, prior to beginning GnRH-agonist therapy
  • Male partner semen analysis within the six months prior to starting GnRH agonist therapy

  • Willingness and ability to comply with the protocol for the duration of the study
  • Written informed consent given prior to any study related procedure not part of the patient's normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

Who cannot join

  • Known to be positive for Human Immunodeficiency Virus
  • Known to be positive for Hepatitis B or C Virus
  • Known allergy to E. coli derived pharmaceutical product
  • Any clinically significant systemic disease (e.g. insulin-dependant diabetes mellitus, epilepsy, severe migraine, intermittent porphyria, hepatic, renal or cardiovascular disease, severe corticosteroid-dependent asthma) or any significant allergic disease (excluding rhinitis, hay fever or sinusitis of ENT origin)
  • Presence of an uncontrolled clinically significant medical condition (including infection) as determined by the investigator
  • Persistent tachycardia defined as heart rate > 90 bpm confirmed by ECG
Show all 17Show fewer
  • Any medical condition, which in the judgement of the investigator may interfere with the absorption, distribution, metabolism or excretion of the drug. In case of doubt, the patient in question was to be discussed with Serono's Study Director
  • More than one previous failed ART cycle, where "failed" is defined as cancellation of administration of hCG due to a poor response to gonadotrophin stimulation (defined as retrieval of three oocytes or less)
  • Any history of difficulties in ET procedure (i.e. requiring general anaesthetic e.g. due to position of cervix)
  • Hyperprolactinaemia, defined as prolactin levels of ³ 1000 mIU/L and/or the patient remained anovulatory despite appropriate dopamine agonist treatment
  • Abnormal undiagnosed gynaecological bleeding
  • Any contraindication to being pregnant and/or carrying pregnancy to term
  • Presence of any medical condition for which the use of gonadotrophin preparations or progesterone was contra-indicated
  • Known allergy or hypersensitivity to gonadotrophin preparations
  • Known intolerance or allergy to paracetamol (acetaminophen)
  • Active substance abuse
  • Previous entry into this study or simultaneous participation in another clinical drug trial

About this study

Official title: A Randomised, Double-blind, Placebo Controlled, Proof of Concept Study to Assess the Efficacy, Safety and Acceptability of r-hLIF for Improving Embryo Implantation Following in Vitro Fertilisation (IVF) and Embryo Transfer (ET) in Women With Recurrent Implantation Failure.

This study was designed to obtain pilot clinical evidence of the efficacy, safety and acceptability of r-hLIF administered during the luteal phase after IVF/intra-cytoplasmic sperm injection (ICSI) and ET for improving embryo implantation in infertile women with a history of at least three implantation failures following ART. Based on LIF expression patterns and experimental data from animal research a role of LIF in embryo implantation is anticipated.

Being tested
Emfilermin, recombinant human leukemia inhibitory factor (r-hLIF)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Emfilermin, recombinant human leukemia inhibitory factor (r-hLIF) in people with Infertility Implantation Failure, run by Merck KGaA, Darmstadt, Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement of embryo implantation and Safety (time frame: Various). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00504530, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jan 2017.
