Outcomes

Primary Outcomes

Percentage of Participants Who Prefer Pembrolizumab Plus Berahyaluronidase Alfa Subcutaneous (SC) As Assessed By Patient Preference Questionnaire (PPQ) Question 1

The PPQ is an instrument that has been developed from participant interviews and includes questions to evaluate directly from participants their preference regarding mode of administration, as well as the strength of the preference, and the reason for the preference. The PPQ does not have any pre-defined scale or associated numerical scoring and answer choices are qualitative. Question 1 in the PPQ evaluates participants' preferred method of administration with response options of IV, SC or "no preference". As pre-specified by the protocol, the percentage of participants who preferred SC administration (participant preference rate \[PPR\]) was reported out of all randomized participants who received all 3 doses of Pembrolizumab IV and Pembrolizumab SC during treatment crossover period and answered at least question 1 of the PPQ on Cycle 6 Day 1 (Day 106).

Time frame: Day 106

Secondary Outcomes

Percentage of Participants Who Preferred SC Administration According to Most Frequent Reasons of Preference As Assessed by PPQ Question 3

The PPQ is an instrument that has been developed from patient interviews and includes questions to evaluate directly from participants their preference regarding mode of administration, as well as the strength of the preference, and the reason for the preference. PPQ Question 3 evaluated 2 main reasons for participants' preference for one of the administration methods (SC or IV), with response options including "feels less emotionally distressing", "requires less time in the clinic", and "lower level injection-site pain". As pre-specified by the supplemental statistical analysis plan (sSAP), the most frequent reasons for preferring SC administration as assessed by PPQ Question 3 were reported among all participants preferring SC in each treatment arm. Treatment arms A (Pembrolizumab Plus Berahyaluronidase alfa SC followed by Pembrolizumab IV) and B (Pembrolizumab IV followed by Pembrolizumab plus Berahyaluronidase alfa SC) were defined as treatment sequence arms in the protocol.

Time frame: Day 106

Percentage of Participants That Were Satisfied or Dissatisfied With the SC Method of Administration According to Level of Satisfaction, As Assessed by Therapy Administration Satisfaction Questionnaire - Subcutaneous (TASQ-SC) Question 1

The TASQ SC is a 12-item questionnaire that asks questions regarding different aspects of participants' satisfaction with SC administration, experiences related to administration, convenience, and time. The TASQ SC does not have any pre-defined scale or associated numerical scoring and answer choices are qualitative. Question 1 in the TASQ SC evaluates participants' satisfaction or dissatisfaction with SC administration. As pre-specified by the sSAP, the percentage of participants was reported for each response to TASQ-SC Question 1 according to level of satisfaction, for each treatment arm. Treatment arms A (Pembrolizumab Plus Berahyaluronidase alfa SC followed by Pembrolizumab IV) and B (Pembrolizumab IV followed by Pembrolizumab plus Berahyaluronidase alfa SC) were defined as treatment sequence arms in the protocol.

Time frame: Up to approximately Day 106

Percentage of Participants That Were Satisfied or Dissatisfied With the IV Method of Administration According to Level of Satisfaction, As Assessed by Therapy Administration Satisfaction Questionnaire -Intravenous (TASQ-IV) Question 1

The TASQ IV is a 12-item questionnaire that asks questions regarding different aspects of participants' satisfaction with IV administration, experiences related to administration, convenience, and time. The TASQ IV does not have any pre-defined scale or associated numerical scoring and answer choices are qualitative. Question 1 in the TASQ IV evaluates participants' satisfaction or dissatisfaction with IV administration. As pre-specified by the sSAP, the percentage of participants was reported for each response to TASQ-IV Question 1 according to level of satisfaction, for each treatment arm. Treatment arms A (Pembrolizumab Plus Berahyaluronidase alfa SC followed by Pembrolizumab IV) and B (Pembrolizumab IV followed by Pembrolizumab plus Berahyaluronidase alfa SC) were defined as treatment sequence arms in the protocol.

Time frame: Up to approximately Day 106

Percentage of Participants Who Chose Pembrolizumab (+) Berahyaluronidase Alfa SC or Pembrolizumab IV for the Treatment Continuation Period on the Participant Choice Questionnaire

The Participant Choice Questionnaire offered participants SC or IV treatment administration choices for the Treatment Continuation Period of the study, and was administered on Day 106 after study intervention administration. As pre-specified by the sSAP, the percentage of participants who chose either SC or IV treatment for the Treatment Continuation Period in the study was reported out of all randomized participants who chose to receive treatment intervention in the Treatment Continuation Period.

Time frame: Day 106

Number of Participants Who Experience an Adverse Event (AE)

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. As pre-specified by the protocol, the number of participants who experience an AE will be reported for the overall study according to treatment arm, defined as a treatment sequence arm in the protocol (i.e., "Pembrolizumab Plus Berahyaluronidase alfa SC followed by Pembrolizumab IV" and "Pembrolizumab IV followed by Pembrolizumab plus Berahyaluronidase alfa SC").

Time frame: Up to ~27 months

Number of Participants Who Discontinue Study Drug Due to an AE

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. As pre-specified by the protocol, the number of participants who discontinue study drug due to an AE will be reported for the overall study according to treatment arm, defined as a treatment sequence arm in the protocol (i.e., "Pembrolizumab Plus Berahyaluronidase alfa SC followed by Pembrolizumab IV" and "Pembrolizumab IV followed by Pembrolizumab plus Berahyaluronidase alfa SC").

Time frame: Up to ~24 months
