Design outcomes

Primary

MeasureTime frame
Main Objective: This is a randomised controlled trial. To see if taking methotrexate (MTX) in combination with gefitinib is better at reducing the need for surgery against methotrexate alone in the treatment of ectopic pregnancy. ;Secondary Objective: To see if taking MTX in combination with gefitinib is better than methotrexate alone in reducing the need for a further dose of MTX. To see if it will reduce the numbers of days until the pregnancy is resolved (pre-pregnancy hormone level of <=15 iu/l which could reduce the number of visits to the hospital. To see if the treatment is safe to use and that women can tolerate the treatment. To see if women are happy taking the treatment. ;Primary end point(s): The need for surgical intervention for treatment of EP (salpingectomy/salpingostomy by laparoscopy/laparotomy) ;Timepoint(s) of evaluation of this end point: End of treatment

Secondary

MeasureTime frame
Secondary end point(s): SECONDARY CLINICAL OUTCOMES: 1) Additional MTX 2) time to hCG resolution (days) from randomisation to hCG level of =15 iu/l 3) number of treatment-associated hospital visits until resolution or scheduled/emergency surgery 4) safety/tolerability 5) Acceptability of treatment 6) Return to menstruation ;Timepoint(s) of evaluation of this end point: Three months post treatment
