New cancer drug interaction study recruits healthy volunteers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

If the mean blood pressure exceeds the limits above, 1 additional triplicate measurement may be taken. * Participant has a mean corrected QT interval using Fridericia's formula (QTcF ) of \> 450 msec on day -1. * Participant tests positive for alcohol at screening or on day -1. * Participant tests positive for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine and opiates) at screening or on day -1. * Participant tests positive for cannabinoids on day -1. * Participant has a positive serology test for hepatitis A virus (HAV) antibodies immunoglobulin M (IgM), hepatitis B (HBc) antibodies, hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies or antibodies to human immunodeficiency virus (HIV ) type 1 and/or type 2 at screening. * Participant has a positive rapid COVID-19 antigen test on day -1. * Participant has any condition that makes the participant unsuitable for study participation. * Participant has a known or suspected hypersensitivity to ASP3082 or any components of the formulation used. * Participant has a history of smoking \> 10 cigarettes (or equivalent amount of tobacco) per day within 3 months prior to day -1 or the participant tests positive for cotinine at screening or day -1. * Participant has a history of consuming \> 10 units of alcoholic beverages per week within 3 months prior to screening (Note: 1 unit = 12 ounces of beer, 5 ounces of wine, 1.5 ounces of spirits/hard liquor). * Participant has used any drugs of abuse (e.g., amphetamines, barbiturates, benzodiazepines, cocaine and/or opiates) within 3 months prior to day -1. * Participant has had significant blood loss, donated ≥ 1 unit (450 mL) of whole blood or donated plasma within 7 days prior to day -1 and/or received a transfusion of any blood or blood products within 60 days prior to day -1. * Participant has had previous exposure to ASP3082. * Participant is an employee of Astellas, the study-related contract research organizations (CROs) or the clinical unit.
