HX044,FIH Study in Patients with Advanced Solid Tumor Malignancies

Subjects will continue on study treatment until the subject develops an intolerable toxicity, withdraws consent, develops progression of disease, death, lost to follow-up, start of new anticancer treatment or up to study treatment duration of 24 months, whichever comes first.
