Design outcomes

Primary

MeasureTime frame
Estimation of whole body dose (effective dose) with C11-HCA2969 administration (Confirm that the effective dose does not exceed 10mSv, which is the upper limit of dose constraints under international standards. For reference, the threshold values for each organ specified by the US Radioactive Drug Research Committee regulation do not exceed 30 mSv (whole body, hematopoietic organs, lens of the eye, gonads) and 50 mSv (others).) Adverse events and side effects

Secondary

MeasureTime frame
Vital signs(systolic/diastolic blood pressure, pulse rate, respiratory rate, temperature) Electrocardiography Clinical examination (hematology, bold biochemistry, urinalysis) Pharmacokinetic evaluation (chronological changes in accumulation in major organs, changes in blood concentration, urinary excretion dynamics)
