Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With Complete Response (CR) or Partial Response (PR) (Objective Response Rate [ORR]) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 14 Months) ]
    ORR was the percentage of participants achieving a best overall response (BOR) of complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the longest diameters (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions.


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: From Date of First Dose until Death Due to Any Cause (Up To 27 Months) ]
    OS defined as the time from first dose date to the date of death due to any cause. For each participant who is not known to have died as of the data-inclusion cutoff date for overall survival analysis, OS time was censored on the last date the participant is known to be alive.

  2. Duration of Response (DOR) [ Time Frame: From Date of CR, PR until Disease Progression or Death Due to Any Cause (Up To 14 Months) ]
    DOR was the time from the date of first evidence of complete response or partial response to the date of objective progression or the date of death due to any cause, whichever is earlier. CR and PR were defined using the RECIST v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. If a responder was not known to have died or have objective progression as of the data inclusion cutoff date, duration of response was censored at the last adequate tumor assessment date.

  3. Progression Free Survival (PFS) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 27 Months) ]
    PFS defined as the time from the first day of therapy to the first evidence of disease progression as defined by RECIST v1.1 or death from any cause. Progressive Disease (PD) was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions. If a participant does not have a complete baseline disease assessment, then the PFS time was censored at the date of first dose, regardless of whether or not objectively determined disease progression or death has been observed for the participant. If a participant was not known to have died or have objective progression as of the data inclusion cutoff date for the analysis, the PFS time was censored at the last adequate tumor assessment date.

  4. Percentage of Participants With CR, PR or SD (Disease Control Rate [DCR]) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 14 Months) ]
    Disease Control Rate (DCR) was the percentage of participants with a best overall response of CR, PR, or Stable Disease (SD) as per Response using RECIST v1.1 criteria. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. SD was neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD for target lesions, no progression of non-target lesions, and no appearance of new lesions.

  5. Percentage of Participants With Tumor Response of Stable Disease (SD) for at Least 6 Months, Partial Response (PR) or Complete Response (CR) (Clinical Benefit Rate) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 14 Months) ]
    Clinical benefit rate defined as percentage of patients with best overall response of CR, PR, or SD with a duration of at least 6 months. CR, PR, or SD were defined using RECIST, v1.1 criteria. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the LD of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. SD was neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD for target lesions, no progression of non-target lesions, and no appearance of new lesions. Percentage of participants = (participants with CR+PR+SD with a duration of at least 6 months /number of participants enrolled) *100.

  6. Number of Participants With Categorical Change From Baseline in Brief Pain Inventory Short Form (mBPI-sf) - Worst Pain Score [ Time Frame: Cycle 6 Day 1 ]
    A self-reported scale that measures the severity of pain based on the average pain experienced over the past 24 hours. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine).

  7. Pharmacokinetics: Area Under the Concentration Versus Time Curve From Time Zero to Infinity (AUC[0-∞]) for Abemaciclib and Metabolites M2 and M20 [ Time Frame: Cycle 1 Day 1 pre dose, Cycle 1 Day 15 4 hours (h) and 7 h post dose, Cycle 2 Day 1 pre dose and 3 h post dose, Cycle 3 Day1 pre dose ]
    Area Under the Concentration versus Time Curve from Time Zero to Infinity (AUC[0-∞]) was evaluated for Abemaciclib and Metabolites M2 and M20

  8. Number of Participants With Categorical Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) - Global Health Status Score [ Time Frame: Cycle 6 Day 1 ]
    EORTC QLQ-C30 v3.0 was a self-administered questionnaire with multidimensional scales that measures 5 functional domains (physical, role, cognitive, emotional, and social), global health status, and symptom scales of fatigue, pain, nausea and vomiting, dyspnea, loss of appetite, insomnia, constipation and diarrhea, and financial difficulties. A linear transformation is applied to standardize the raw scores to range between 0 and 100 per developer guidelines. For functional domains and global health status, higher scores represent a better level of functioning. For symptoms scales, higher scores represented a greater degree of symptoms.
