| E.2.3 | Trial contains a sub-study | No |
| 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.
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 pretreatment 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 pretreatment 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) or ≥ 1.2L/Sec 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 and female participants who are at least 18 years of age at the time of signing the informed consent.
13. If male, agree to the following during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention. The length of time required to continue contraception for each study intervention is as follows:
- Olaparib and platinum doublet: 90 days
-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
-Uses 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. Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penilevaginal intercourse or use a male condom during each episode of penilevaginal penetration.
14.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 the time needed to eliminate each study intervention 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 length of time required to continue contraception for each study intervention is as follows:
- Pembrolizumab: 120 days
- Olaparib and platinum doublet: 180 days
The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention.
• Has 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.
• Abstains from breastfeeding during the study intervention period and for at least the following period after the last study intervention:
- Pembrolizumab: 120 days
- Olaparib: 7 days
• Medical history, menstrual history, and recent sexual
activity reviewed by the investigator to decrease the risk for inclusion of a woman with an early undetected pregnancy
15.The participant (or legally acceptable representative) has provided
documented informed consent/assent for the study. The participant may also provide consent/assent for FBR. However, the participant may participate in the main study without participating in FBR. |
