A Study Of Avelumab Alone Or In Combination With Pegylated Liposomal Doxorubicin Versus Pegylated Liposomal Doxorubicin Alone In Patients With Platinum Resistant/Refractory Ovarian Cancer (JAVELIN Ovarian 200)

OS is defined as the time from the date of randomization to the date of death due to any cause. OS time was summarized by treatment arm using the Kaplan-Meier method.

PFS is defined as the time from date of randomization to the date of the first documentation of progression of disease (PD) or death due to any cause, whichever occurs first. PFS time was summarized by treatment arm using the Kaplan-Meier method. PFS based on BICR assessment was evaluated for this endpoint.

Percentage of participants achieved objective response (OR) based on BICR assessment is presented for this endpoint. OR is defined as a complete response (CR, disappearance of all target lesions) or partial response (PR, >=30% decrease under the baseline of the sum of diameters of all target measurable lesions) according to the RECIST (version 1.1) recorded from randomization until disease progression or death due to any cause. Both CR and PR must be confirmed by repeat assessments performed no less than 4 weeks after the criteria for response are first met and before the first documentation of disease progression. Only tumor assessments performed on or before the start date of any further anti-cancer therapies are considered in the assessment of best overall response.

Percentage of participants achieved OR based on investigator assessment is presented for this endpoint. OR is defined as a CR (disappearance of all target lesions) or PR (>=30% decrease under the baseline of the sum of diameters of all target measurable lesions) according to the RECIST (version 1.1) recorded from randomization until disease progression or death due to any cause. The ORR on each randomized treatment arm were estimated by dividing the number of participants with OR (CR or PR) by number of participants randomized to the respective treatment arm.

PFS is defined as the time from date of randomization to the date of the first documentation of PD or death due to any cause, whichever occurs first. PFS time was summarized by treatment arm using the Kaplan-Meier method.

DR is defined, for participants with an OR per RECIST version 1.1, as the time from the first documentation of objective tumor response (CR [disappearance of all target lesions] or PR [>=30% decrease under the baseline of the sum of diameters of all target measurable lesions]) to the first documentation of objective tumor progression or death due to any cause, whichever occurs first.

DR is defined, for participants with an OR per RECIST version 1.1, as the time from the first documentation of objective tumor response (CR [disappearance of all target lesions] or PR [>=30% decrease under the baseline of the sum of diameters of all target measurable lesions]) to the first documentation of objective tumor progression or death due to any cause, whichever occurs first.

Percentage of participants achieving DC based on BICR assessment is presented in this endpoint. DC is a best overall response of CR (disappearance of all target lesions), PR (>=30% decrease under the baseline of the sum of diameters of all target measurable lesions), non-complete response/non-progressive disease or stable disease (SD) according to the RECIST version 1.1.

Percentage of participants achieving DC based on investigator assessment is presented in this endpoint. DC is a best overall response of CR (disappearance of all target lesions), PR (>=30% decrease under the baseline of the sum of diameters of all target measurable lesions), non-complete response/non-progressive disease or SD according to the RECIST version 1.1.

An adverse event (AE) is any untoward medical occurrence in a clinical investigation patient administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect; progression of the malignancy under study. Treatment emergent AEs are those events with onset dates occurring during the on-treatment period for the first time, or if the worsening of an event is during the on-treatment period.

The number of participants with following laboratory abnormalities meeting any of the Grades 1 to 4 classified according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) toxicity grading version 4.03 were summarized: hematology (anemia, lymphocyte count decreased, neutrophil count decreased; and platelet count decreased) and chemistry laboratory tests (creatinine increased; serum amylase increased and lipase increased).

Vital signs included blood pressure and pulse rate. Changes from baseline in sitting diastolic blood pressure (DBP) and systolic blood pressure (SBP) were summarized.

Vital signs included blood pressure and pulse rate. Changes from baseline in sitting pulse rate were summarized.

Categorical summarization ECG criteria were as follows: 1) QT interval, QTcB, QTcF and QTcP: increase from baseline >30 ms or 60 ms; absolute value > 450 ms, >480 ms and > 500 ms; 2) heart rate (HR): change from baseline >=20 bpm and absolute value <=50 bpm or >=120 bpm; 3) PR interval: absolute value >=220 ms and increase from baseline >=20 ms; 4) QRS: >= 120 ms.

LVEF decrease was summarized by multiple-gated acquisition (MUGA)/ echocardiogram (ECHO) parameter. Participants with a LVEF% >=10 points and >= 15 points decrease from baseline during the on-treatment period were summarized.

PD-L1 expression was assessed by immunohistochemistry. Participants were considered positive for PD-L1 if their baseline tissue sample demonstrated PD-L1 expression on >=1% of tumor cells or >=5% of immune cells.

Tumor infiltrating CD8 positive (CD8+) T lymphocytes was assessed by immunohistochemistry. Participants were considered positive for CD8 T cells if their baseline tissue sample demonstrated presence of >=1% CD8+ cells across the area of the tumor.

The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30) is a 30 question survey and includes 5 functional domain subscales, global health status/quality of life, disease/treatment related symptoms, and the perceived financial impact of disease. Higher scores are reflective of a greater presence of symptoms.

The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Ovarian Cancer 28 (EORTC QLQ-OV28) is a 28 item instrument with 7 functional domain subscales. Time to deterioration was defined as the time from randomization to the first time the participant's score showed a 15-point or higher increase in the score of the abdominal/GI symptom subscale of the EORTC QLQ-OV28.

The EuroQol- 5 Dimensions- 5 Levels (EQ-5D-5L) questionnaire consists of the EQ-5D-5L descriptive system and a visual analogue scale (the EuroQol-visual analogue scale [EQ-VAS]). The respondent's self-rated health is assessed on a scale from 0 (worst imaginable health state) to 100 (best imaginable health state) by the EQ-VAS.

Ctrough was defined as predose concentration during multiple dosing, and can be observed directly from data.

Cmax was defined as maximum observed serum concentration, and can be observed directly from data.

Cmax was defined as maximum observed serum concentration, and can be observed directly from data.

AUC24 was defined as area under the concentration time profile from time zero to 24 hours.

AUC336 was defined as area under the concentration time profile from time zero to 336 hours.

AUClast was defined as area under the concentration time profile from time zero to the time of the last quantifiable concentration (Clast).

Treatment-boosted ADA was defined as a positive ADA result at baseline and the titer ≥ 8×baseline titer at least once after treatment with avelumab.

Treatment-induced ADA was defined as participant who was ADA-negative at baseline and has at least one positive post-baseline ADA result; or if participant did not have a baseline sample, the participant had at least one positive past-baseline ADA result.

Treatment-induced nAb was defined as participant who was not nAb positive at baseline and had at least one positive post-baseline nAb result; or if participant did not have a baseline sample, the participant had at least one positive past-baseline ADA result.
