What was measured

Tumor response was assessed by CT or MRI. PFS was defined as the time (months) from date of first dose date of study drug for participants in Part 1 until date of documented disease progression or death due to any cause, whichever occurred first. More specifically, PFS was determined using all the assessment data up until the last evaluable visit prior to or on the date of i) disease progression as defined by RECIST 1.1 or by clinical criteria as determined by the investigator; or ii) withdrawal of consent; or iii) receiving subsequent anticancer therapy, whichever was earlier. For PFS determined using response data derived programmatically, either clinical progression or progression by RECIST (whichever came first) was considered. Median and inter-quartile range of PFS were calculated using the Kaplan-Meier method.

Analysis population: The FAS included all randomized patients who received at least 1 dose of study drug (etoposide, carboplatin, or trilaciclib). Analyses using the FAS were conducted on the basis of the assigned treatment.
