Brief summary: The primary purpose of part 1 (dose escalation) of this study is to identify the recommended dose and to characterize the safety and tolerability of Debio 0123 in combination with carboplatin and etoposide.

The primary purpose of part 2 (dose expansion) of this study is to characterize the safety and tolerability of Debio 0123 at the recommended dose when administered in combination with carboplatin and etoposide.

13. Immunization with live or live-attenuated vaccine within 28 days prior to first dose of study treatment.
14. Inability or unwillingness to swallow oral medications.
15. Chemotherapy, monoclonal antibodies/biologics, or radiotherapy with curative intent within 28 days prior to first dose of study treatment. Palliative radiation is allowed up to 1 week prior to study treatment start.
16. Unresolved AEs or toxicities due to previous treatments \>Grade 1. Note: Participants with ≤Grade 2 alopecia or endocrinopathies controlled by replacement therapy are exceptions and may qualify for the study.
17. Hypersensitivity to Debio 0123, etoposide or carboplatin, or any of the excipients found in the formulations for Debio 0123, etoposide, or carboplatin. If a prior hypersensitivity to carboplatin has been observed but a successful desensitization was performed for the participant, he or she may be eligible for the study.
18. Prior exposure to any WEE1 inhibitor

Note: Other inclusion/exclusion criteria mentioned in the protocol may apply.
