E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Infertility defined as lack of conception despite 12 months of unprotected intercourse, or three cycles of donor insemination without pregnancy or three ovulatory ovulation induction cycles without pregnancy |
|
E.1.1.1 | Medical condition in easily understood language |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Female diseases of the urinary and reproductive systems and pregancy complications [C13] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if the additional tubal flushing with oil-based contrast after undergoing Hyfosy significantly improves the occurrence rate of live birth, counting from the first day of the last menstrual cycle in which the patient conceives within 6 months after Hyfosy compared to no additional flushing after undergoing Hyfosy. |
|
E.2.2 | Secondary objectives of the trial |
• To compare reproductive outcomes
• To compare gestational age at delivery, pregnancy complications and neonatal outcomes like birth weight, neonatal mortality, major congenital anomaly and thyroid function of the child(ren) between the intervention and the control group for women achieving a pregnancy > 22 weeks
• To compare maternal thyroid function between the intervention and the control group:
• To compare number of complications during or immediately after the intervention between the intervention and the control group
• To compare pain scores of the Hyfosy between the intervention and the control group and to compare pain scores between Hyfosy and flush in the intervention group
• To compare the general quality of life (EQ-5D-5L) and disease-specific quality of life (FertiQol questionnaire) (20, 21) between the intervention and the control group
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Infertile women undergoing Hyfosy as part of the fertility workup.
Women will be eligible if they
• are ≥ 18 years and < 40 years
• have infertility defined as
o lack of conception despite 12 months of unprotected intercourse OR;
o if they are taking part in a donor sperm insemination programme: three cycles of donor insemination without pregnancy OR;
o in case of treated ovulation disorder: three ovulatory ovulation induction cycles without pregnancy
• have tubal patency of at least one Fallopian tube on Hyfosy
|
|
E.4 | Principal exclusion criteria |
Women with
• known iodine allergy
• ovulation disorders defined as less than eight menstrual cycles per year who did not have three ovulatory cycles after ovulation induction
• contra-indication to have tubal patency testing according to the site’s indication
• active thyroid disorders (other than treated subclinical hypothyroidism because these may be included)
• untreated subclinical hypothyroidism (TSH>2.5IU/L)
• uterine surgery in the past two months before Hyfosy
• a male partner (if applicable) with a post-wash Total Motile Sperm Count (TMC) < 1x106 and/or TMC < 3x106 in the native sperm analysis [TMC is defined as volume X concentration X (A (progressive) + B (non progressive) motility in %) divided by 100]
• an indication for IVF
• no Belgian national number (RRN/INS)

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the occurrence of live birth, counting from the first day of the last menstrual cycle in which the patient conceives within 6 months after Hyfosy.
The endpoint is chosen to reflect efficacy (beneficial effect of the tubal flush with 5-10mL OSCM compared to Hyfosy without additional flushing).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Reproductive outcomes: clinical pregnancy, ongoing pregnancy, ectopic pregnancy, multiple pregnancy and miscarriage
• For women achieving a pregnancy > 22 weeks:
o Gestational age at delivery
o Birth weight
o Neonatal mortality
o Major congenital anomaly
o Neonatal outcomes and thyroid function of the child(ren)
o Pregnancy complications
• Maternal thyroid function: TSH, FT4 at 4 weeks, 26 weeks for all patients and at delivery or end of pregnancy when pregnant
• Number of complications during or immediately after the intervention (embolism, anaphylactic shock, pelvic inflammatory disease)
• Pain score of the Hyfosy (as measured by VAS)
• Pain score of the additional flush (as measured by VAS) in the intervention group
• General (EQ-5D-5L) and disease-specific quality of life (FertiQol questionnaire)
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
• Reproductive outcomes: during pregnancy
• For women achieving a pregnancy > 22 weeks: Post-partum
• Maternal thyroid function: at 4 weeks, 26 weeks for all patients and at delivery or end of pregnancy when pregnant
• Number of complications during or immediately after the intervention
• Pain scores: immediately after Hyfosy and intervention
• General (EQ-5D-5L) and disease-specific quality of life (FertiQol questionnaire): 26 weeks
