General information about the trial
|
|||
Main objective of the trial |
To evaluate the efficacy of a single intramuscular injection of MTX (50mg/m2) and seven days of oral gefitinib 250mg in regressing stable ectopic pregnancies with a serum human chorionic gonadotrophin level at presentation (reflects ectopic pregnancy size) of between 1000-10,000 IU/L.
It was a single arm trial that aimed to recruit 50 participants who met the inclusion criteria. It was powered to show the drug is at least 70% effective in successfully resolving ectopic pregnancies without need for surgery.
This trial also set out to further collect information on safety and tolerability of the drug.
|
||
Protection of trial subjects |
For protection of subjects
1) The trial was overseen by a Trial Steering Committee who had a member assessing safety sitting on the committee. In addition, this committee comprised of members from The University of Melbourne (2 Professors) and an independent Professor of Reproductive Biology at the University of Edinburgh.
2) The protocols had full REC approval and all participants provided written, informed consent
3) All adverse / serious adverse outcomes were formally reported to REC committees.
4) All trial subjects were aware of what to do in an event of any emergency: contact details for the hospital as well as a phone number where they could contact study investigators.
|
||
Background therapy |
All participants had the standard intramuscular methotrexate dose that is widely used to medically treat ectopic pregnancies. Thus, all were given a single intramuscular injection of methotrexate (50mg/m2), but they also then were given seven tablets of 250 mg of gefitinib (the trial medication). | ||
Evidence for comparator |
This was a single arm trial and there was no comparator arm. The thought when designing this small trial was that it was premature to embark of a formal randomised trial therefore the next step was this small single arm phase II study. | ||

Recruitment

Recruitment details |
We recruited participants between March 2012 and April 2014. Participants were recruited from 3 Australian Centres and 1 in Edinburgh. Recruitment was done in the early pregnancy units where investigators were alerted by staff of potential participants who were diagnosed with an ectopic pregnancy that may fit the criteria as per our protocol. | ||||||||||
