New hope for tough lung cancer: tarlatamab trial targets advanced disease

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

Prior/Concomitant Therapy * Currently or previously enrolled in a tarlatamab study. * Prior therapy with any selective inhibitor of the DLL3 pathway. * Prior anti-cancer therapy within 21 days prior to first dose of study treatment, with certain exceptions. * Receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug, with certain exceptions. * Treatment with live virus, including live-attenuated vaccination, within 14 days prior to the first dose of study drug. Inactive vaccines (eg, non-live or non-replicating agent) and live viral non-replicating vaccines (eg, Jynneos for mpox infection) within 3 days prior to first dose of study drug. Prior/Concurrent Clinical Study Experience • Currently receiving treatment in another investigational device or drug study, or less than 30 days since ending treatment on another investigational device or drug study(ies). Other investigational procedures while participating in this study are excluded. Other Exclusions * Female participants of childbearing potential unwilling to use protocol-specified method of contraception during treatment and for an additional period of time after the last dose of study drug as specified in the study protocol. * Female participants who are breastfeeding or who plan to breastfeed while on study and for an additional period of time after the last dose of study drug as specified in the study protocol. * Female participants planning to become pregnant or donate eggs while on study and for an additional period of time after the last dose of study drug as specified in the study protocol. * Female participants of childbearing potential with a positive pregnancy test assessed at screening by a highly sensitive serum pregnancy test. * Male participants with a female partner of childbearing potential who are unwilling to practice sexual abstinence (refrain from heterosexual intercourse) or use contraception during treatment and for an additional period of time after the last dose of study drug as specified in the study protocol. * Male participants with a pregnant partner who are unwilling to practice abstinence or use a condom during treatment and for an additional period of time after the last dose of study drug as specified in the study protocol. * Male participants unwilling to abstain from donating sperm during treatment and for an additional period of time after the last dose of study drug as specified in the study protocol. * Participants has known sensitivity to any of the products or components to be administered during dosing. * Participants likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures. * History or evidence of any other clinically significant disorder, condition, or disease that, in the opinion of the investigator or medical monitor if consulted, would pose a risk to participant safety or interfere with the study evaluation, procedures, or completion.
