The main purpose of this study is to evaluate how safe and effective LY4336619 is in adults with advanced cancer. Some participants will receive LY4336619 alone, and some will receive it with another cancer medicine. Participants will be in the study for up to 2 years, depending on how they tolerate and respond to treatment.Read full original descriptionShow less
A First-in Human, Phase 1 Trial to Assess Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of LY4336619, an Alkaline Phosphatase Placental-Like 2 (ALPPL2) T- Cell Engager Bispecific Antibody, in Adult Participants With Advanced Solid Tumors

Inclusion: Have histological diagnosis of locally advanced or metastatic solid tumor malignancy; Have a life expectancy of at least 12 weeks as judged by the investigator; Must be an appropriate candidate for study treatment. Study treatment is considered appropriate where approved measures are no longer effective or are not considered appropriate or safe in the opinion of the investigator, or the individual refuses the remaining most appropriate standard of care treatment; Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) scale or Karnofsky performance status of at least 80%.
Exclusion: Residual symptoms of neurotoxicity from prior chimeric antigen receptor-modified T cell (CAR-T) or bispecifics; Has any unresolved toxicities from prior therapy greater than National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v6.0 Grade 1 at the time of starting study treatment except for alopecia, endocrine adverse events (AEs) on replacement therapy, and Grade 2 neuropathy; Has a known or suspected history of active central nervous system (CNS) involvement; Has a history of carcinomatous meningitis; Current or history of CNS disease, such as stroke, epilepsy, CNS vasculitis, or neurodegenerative disease; Has significant cardiovascular disease; Has an active uncontrolled systemic bacterial, viral, fungal, or parasitic infection (except for fungal nail infection), or other clinically significant active disease process which, in the opinion of the investigator and the sponsor, makes it undesirable for the individual to participate in the trial. Screening for chronic conditions is not required.
