Description
Inclusion Criteria:
- Signed informed consent including willingness to undertake 3 MRI investigations in one day.
- Females with endometriosis or suspected endometrial lesions at transvaginal ultrasound examination.
- At least 18 years of age when signing the informed consent.
Adequate renal and hepatic function:
eGFR ≥ 50 mL/min/1.73 m2, bilirubin <1 x upper limit of normal (ULN), creatinine <1 x ULN, ASAT and ALAT < 1 x ULN, Bilirubin ULN: 25 µmol/L, creatinine ULN: 90 µmol/L, ASAT ULN: 0.60 µkat/L and ALAT ULN: 0.75 µkat/L) at the screening visit.
Females of child-bearing potential* must agree to the use of effective contraception** or practice abstinence during the study and for 30 days after the IMP administration.
*A female of child-bearing potential is a sexually mature female who 1) has not undergone a hysterectomy or bilateral oophorectomy, or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e. had had menses at any time in the preceding 24 consecutive months).
**Effective contraception is defined as contraceptive methods with a failure rate of < 1% to prevent pregnancy (combined [oestrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD]or intrauterine hormone-releasing system [IUS]).
- Adequate haematological function: haemoglobin (Hb) ≥90 g/L, absolute neutrophil count (ANC) ≥1.3x109 /L and platelet count ≥ 100 x 109 /L.
Exclusion Criteria:
- Female participants who are pregnant or who are currently breast feeding.
- Conditions contraindicating MRI including, but not limited to, BMI > 40 kg/m2 at screening claustrophobia, metallic implants or internal electrical devices (e.g., cochlear implant, nerve stimulator, gastric pacemaker, bladder stimulator, pacemaker, defibrillator, artificial valves in heart, aneurysm clips, etc.), and permanent makeup or tattoos which in the Investigator's opinion might jeopardise the patient's safety or interfere with the imaging measurements. The Investigator is encouraged to contact the MR clinic for advice on which implants, tattoos, etc may be unsuitable.
- Moderate to severe hypertension as judged by the Investigator.
- History of significant cardiovascular disease such as myocardial infarction, congestive heart failure, stroke, serious cardiac arrhythmias, history of angina within 6 months prior to screening.
- Clinically diagnosed obstruction of bile duct as judged by the Investigator.
- Electrocardiogram (ECG) abnormalities in the standard 12-lead ECG (at screening) which, in the opinion of the Investigator is clinically relevant, or will interfere with the ECG analysis.
- Abnormalities detected during examination at screening and admission, which in the opinion of the Investigator, may either put the patient at risk because of participation in the study or influence the results or the patient's ability to participate in the study.
- Active infection requiring systemic treatment within one week prior to agent administration.
- History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the patient at risk because of participation in the study, or influence the results or the patient's ability to participate in the study.
- Known human immunodeficiency virus (HIV) infection, active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection requiring treatment. Participants with chronic HBV or HCV infection are eligible at the Investigator's discretion provided that the disease is stable and sufficiently controlled under treatment.
- Any use of alcohol within 24 hours of admission to the clinic.
- Plasma donation within 1 month of screening or any blood donation or corresponding blood loss during 3 months prior to screening.
- Use of investigational agent within four weeks before Visit 1 or plans to initiate treatment with an investigational agent during the study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
MRI enhancing effect
Time Frame: Day 1
|
MRI enhancing effect will be evaluated by assessing changes between pre-dose images and post-dose images acquired using longitudinal relaxation time (T1)-weighted imaging sequences, analysing contrast-to-noise in endometriosis lesions vs reference tissue, signal-to-noise in endometriosis lesions.
Additional MR-scan characteristic parameters may be calculated if deemed appropriate.

Measure Description |
Time Frame |
---|---|---|
Diagnostic Value Evaluation for endometriosis lesions.
Time Frame: Day 1
|
Compare the number, size and site of endometriosis lesions obtained by SN132D imaging to transvaginal ultrasound (TUS) and clinically used non-contrast MRI
|
Day 1
|
Diagnostic Value Evaluation for deep pelvic endometriosis lesions.
Time Frame: Day 1
|
Compare the number, size and site of deep pelvic endometriosis lesionsobtained by SN132D imaging to transvaginal ultrasound (TUS) and clinically used non-contrast MRI
|
Day 1
|
Number of treatments related adverse events (AEs)
Time Frame: Day 1 up to 2 weeks
|
Day 1 up to 2 weeks
