Eligibility

Recruits 903 Vulnerable population flag is selected in the trial record. Study enrols adults (Male or female participants aged 18 years or older).

Pregnancy Exclusion
Treatment phase: Females who are known to be breastfeeding or pregnant as determined by a serum pregnancy test (β-HCG) prior to the administration of any trial treatment (once during the treatment phase). Since β-HCG over expression can be also elevated in some tumor types, a positive result should be confirmed with a validated alternative test (e.g., ultrasound).
