- •Patient needs to be surgically sterile, post-menopausal or pre-menopausal with a negative urine pregnancy test before administration of 6qc-ICG. Premenopausal patients who are not surgically sterile have to agree to use an effective method of contraception for at least 30 days after their last dose of study treatment. (part B)
- •Patient has a 12-lead ECG and clinical laboratory test results that are within normal limits, or if any are outside of normal limits they are considered clinically insignificant at the discretion of the investigator. (part B)

- •Subject is in good general health, according to the investigator’s judgement based on vital signs, medical history, physical examination, and laboratory tests performed (part A).
- •Subject has a body mass index between 18-32 kg/m2 (inclusive) and with a minimum body weight of 50 kg at screening (part A)
- •Subject needs to be surgically sterile, post-menopausal or pre-menopausal with a negative urine pregnancy test at screening and before administration of 6qc-ICG. Premenopausal subjects who are not surgically sterile have to agree to use an effective method of contraception (part A)
- •Subject’s screening ECG and clinical laboratory test results are within normal limits, or if any are outside of normal limits they are considered to be clinically insignificant (part A).
- •Subject has negative test results for drug and alcohol screening. (part A)
- •Subject has sufficient application area of healthy intact skin of the back (>100 cm2). (part A)
- •Written informed consent must be given prior to any study activities, according to ICH/GCP and national/local regulations. (part A and B)
排除标准
- •(A history of) any clinically significant medical condition or abnormalities, as judged by the investigator, in physical examination, laboratory test results (including chemistry panel with hepatic and renal panels, complete blood count, and urine dipstick) or electrocardiography (ECG) at screening. In the case of uncertain or questionable results, tests performed during screening may be repeated to confirm eligibility or judged by the investigator to be clinically irrelevant for healthy subjects. (part A)
- •Subject has taken anticoagulant medication, such as heparin, low molecular weight (LMW)-heparin, warfarin, antiplatelets (except low-dose aspirin ≤81 mg which will be allowed), within 2 weeks prior to Day 1, or has a contraindication to skin biopsies. (part A)
- •Subjects that are lactating or pregnant. (part A)
- •The subject has a positive screening test for hepatitis B, hepatitis C, or human immunodeficiency virus. (part A)
- •Use of any prescription medication and any other substance that in the opinion of the investigators may influence the outcome of the study within 7 days prior to study drug administrations, or less than five half-lives (whichever is longer, and during the course of the study). (part A)
- •Previous inclusion in this study. (part A)
- •Participation in a clinical trial within 3 months or 5 half-lives (if half-life is known), whichever is longer. (part A)
- •Use of alcohol during the 24 hours prior to screening and/or an unwillingness to abstain from alcohol consumption during the stay at the clinical unit, and for at least 24 hours prior to each study visit; (part A)
- •Positive urine drug screen or alcohol test at screening and/or at first study day. (part A)
- •History of anaphylactic reactions to a prescription drug, over-the-counter drug, or herbal supplement. (part A)
- •Loss or donation of blood over 500 mL within four months prior to screening. (part A)
- •Subject has a history of skin disease or presence of skin condition that, in the opinion of the investigator, would interfere with the study assessments. (part A)
- •Any other condition that in the opinion of the investigator would complicate or compromise the study or the well-being of the subject. (part A)
- •Patient has a radiologic complete response of the primary tumor (rCR) after neoadjuvant therapy. (part B)
- •Patient has a history of surgery and/or radiation on the ipsilateral breast. (part B)
- •Patient has a history of clinically significant allergies or anaphylactic reactions. (part B)
- •Patient has any condition that in the opinion of the investigators could potentially jeopardize the patient’s well-being or the study objectives. (part B)
- •Patient has hyperthyroidism defined as TSH < 0.15 mU/l and free T4 > 24.0 pmol/l. (part B)
- •Patient has an impaired renal function defined as eGFR<50 ml/min/1.73m
- •Patient has an impaired liver function defined as values greater than 3x the upper limit of normal (ULN) for ALT, AST, or 2x the upper limit of normal for total bilirubin (part B)
- •Patient participates in another clinical trial for which the patient receives a fluorophore perioperatively. (part B)
- •Patient is lactating or pregnant. (part B)
- •Subject has presence of any tattoos, scratches, open sores, excessive hair, or skin damages in the target treatment area(s) that, in the opinion of the investigator, may interfere with study evaluations. (part A)
- •Patient has any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial. (part B)
- •Subject has a Fitzpatrick’s Skin Phototype ≥
- •Subject has had excessive sun exposure, is planning a trip to a sunny climate, or has used tanning booths within 4 weeks prior to Day 1 or is not willing to minimize natural and artificial sunlight exposure during the study. Use of sunscreen products (except on application areas) and protective apparel are recommended when sun exposure cannot be avoided. (part A)
- •Subject has received laser treatment, electrolysis on the application areas within 4 weeks prior to Day 1 or is planning to during the study period. (part A)
- •Subject has shaved the application area 72 hours prior to Day 1 or is planning to do so during the study period. (part A)
- •Subject has used a topically applied treatment on the targeted application area(s) within 1 week prior to Day
