E.3 | Principal inclusion criteria |
1.Has pathologically (histologically or cytologically) confirmed SCLC. 2.Has LS-SCLC (Stage I-III, by AJCC 8th Edition Cancer Staging), and can be safely treated with definitive radiation doses. 3.Has no evidence of metastatic disease by whole body PET/CT scan, CT or MRI scans of diagnostic quality of chest, abdomen, pelvis and brain. The process for image collection and transmission to the central imaging vendor can be found in the Site Imaging Manual. 4.Has at least 1 lesion that meets the criteria for being measurable, as defined by RECIST 1.1, and is appropriate for selection as a target lesion, as determined by local site investigator/radiology review. 5.Has not received prior treatment (chemotherapy or radiotherapy or surgery resection) of LS-SCLC. 6.Is not expected to require tumor resection during the course of the study. 7.Must submit a pre-treatment tumor tissue sample. Any available tumor tissue sample can be submitted: histologic (ie, core, incisional, or excisional biopsy) or cytologic sample (if tissue sample unavailable). The sample should be submitted before or within 4 weeks after randomization; however, participants may be enrolled into the study before the pre-treatment tissue sample is submitted. 8.Has ECOG Performance score 0 or 1 assessed within 7 days prior to the first administration of study intervention. 9.Has a life expectancy of at least 6 months. 10.Has adequate PFT defined as an FEV1 >50% of predicted normal volume and a DLCO >40% of predicted normal value. Participants for whom DLCO measurements are not available will be deemed to have adequate oxygen transfer if pulse oximetry (O2 saturation) ≥90% room air. 11.Has adequate organ function; all screening laboratory tests should be performed within 10 days prior to initiation of study intervention. 12.Male participants are eligible to participate if they agree to the following during the intervention period and for at least 180 days after the last dose of study intervention: -Refrain from donating sperm PLUS either: -Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR -Must agree to use contraception unless confirmed to be azoospermic (vasectomized or secondary to medical cause) as detailed below: Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant.
Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. 13.A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies: -Is not a WOCBP OR -Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), during the intervention period and for at least 180 days after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention. -A WOCBP must have a negative highly sensitive pregnancy test (as required by local regulations) within 24 hours for urine or within 72 hours for serum before the first dose of study intervention. If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive. -Additional requirements for pregnancy testing during and after study intervention as located in Protocol. -The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy. -Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. 14.The participant (or legally acceptable representative if applicable) provides written informed consent/assent for the study. The participant may also provide consent/assent for future biomedical research. However, the participant may participate in the main study without participating in future biomedical research. |
