  • Discontinued all prior treatment for cancer at least 14 days prior to initial dose of study treatment.
  • Adequate organ function.
  • allow alanine aminotransferase (ALT) or aspartate aminotransferase (AST) up to 5x upper limit of normal (ULN) if liver metastases.
  • allow bilirubin up to 2.5 times ULN if elevation is not associated with other signs of liver toxicity or can be explained by mechanical obstruction - requires clinical research physician approval.

Exclusion criteria

  • Have a personal history of any of the following conditions: syncope of either unexplained or cardiovascular etiology, ventricular arrhythmia (including but not limited to ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. Exception: Participants with controlled atrial fibrillation for >30 days prior to study treatment initiation are eligible.

Primary outcomes

  1. Stage 1: Disease Control Rate (DCR): Percentage of Participants With a Best Overall Response of Complete Response (CR), Partial Response (PR) or Stable Disease (SD)

    Time frame: Baseline to Measured Progressive Disease or Start of New Anticancer Therapy (Up to 6 Months)

    Disease control rate (DCR) is the percentage of participants with a best overall response of CR, PR or SD as defined by RECIST v1.1. CR is defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) for target lesions, no progression of non-target lesions, and no appearance of new lesions. PD is defined as 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.

  2. Stage 2: Progression Free Survival (PFS)

    Time frame: Baseline to Measured Progressive Disease or Death Due to Any Cause (Up to 6 Months)

    PFS was defined as the time from the date of randomization until first observation of objective progressive disease as defined by RECIST v1.1 or death from any cause, whichever comes first. PD is defined as 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 patient does not have a complete baseline disease assessment, then the PFS time will be censored at the randomization date, regardless of whether or not objectively determined disease progression or death has been observed for the patient; otherwise, if a patient is not known to have died or have objective progression as of the data inclusion cutoff date for the analysis, the PFS time will be censored at the last complete objective progression-free disease assessment date.

Secondary outcomes

  1. Stage 1: Objective Response Rate (ORR): Percentage of Participants With a Best Overall Response (BOR) of CR or PR

    Time frame: Baseline to Measured Progressive Disease or Start of New Anti-Cancer Therapy (Up to 6 Months)

    Objective response rate (ORR) is the percentage of participants with a BOR of CR or PR as defined by RECIST v1.1. CR is defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR is 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.

  2. Stage 1: Pharmacokinetics (PK): Mean Steady State Exposure of Abemaciclib and Its Metabolites (LSN2839567 (M2), LSN3106726 (M20))

    Time frame: Cycle(C)1 Day(D)14: 0 hour(h),0.5h,1h,2h,4h,6h,8h post dose

    Mean steady state exposure was reported as measured by maximum observed plasma concentration (Cmax).

  3. Stage 1: PK: Area Under the Curve (AUC) (AUC[Tau]) of LY3023414

    Time frame: Cycle 1 Day 1 through Cycle 4 Day 1 (28 Day Cycles)

  4. Stage 1: PK: Maximum Concentration (Cmax) at Steady State of LY3023414

    Time frame: Cycle 1 Day 1 through Cycle 4 Day 1 (28 Day Cycles)

  5. Stage 2: Disease Control Rate (DCR): Percentage of Participants With a Best Overall Response of CR, PR, and SD

    Time frame: Baseline to Measured Progressive Disease or Start of New Anticancer Therapy (Up to 6 Months)

  6. Stage 2: Clinical Benefit Rate (CBR): Percentage of Participants With Best Overall Response of CR, PR, or SD With Duration of SD for at Least 6 Months

    Time frame: Baseline to Disease Progression or Start of New Anticancer Therapy (Up to 6 Months)

    Clinical benefit rate (CBR) is the percentage of participants with a BOR of CR or PR, or SD ≥6 months. CR is defined as the disappearance of all target and non-target lesions & no appearance of new lesions. PR is 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 is 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. PD is defined as 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.

    No participants were enrolled to stage 2; however, results for stage 2 outcomes are reported from the data collected for participants enrolled to stage 1.

  7. Stage 2: Duration of Response (DoR)

    Time frame: Date of CR or PR to Date of Disease Progression or Death Due to Any Cause (Up to 6 Months)

  8. Stage 2: Overall Survival (OS)

    Time frame: Baseline to Death from Any Cause (Up to 10 Months)

    OS duration is measured from the date of randomization to the date of death from any cause. for participants who is not known to have died as of the data-inclusion cutoff date, OS was censored at the last known alive date.

    No participants were enrolled to stage 2; however, results for stage 2 outcomes are reported from the data collected for participants enrolled to stage 1.

  9. Stage 2: Change From Baseline in Carbohydrate Antigen 19.9 (CA 19-9) Level

    Time frame: Baseline, 6 Months

    No participants were enrolled to stage 2; however, results for stage 2 outcomes are reported from the data collected for participants enrolled to stage 1.

  10. Stage 2: Change From Baseline in Pain and Symptom Burden Assessment on the Modified Brief Pain Inventory-Short Form (mBPI-sf)

    Time frame: Baseline, 6 Months

    mBPI-sf is an 11-item instrument used as a multiple-item measure of cancer pain intensity. In addition to pain intensity (4 items), the mBPI-sf is designed for participants to record the presence of pain in general, pain relief, and pain interference with function (general activity, mood, ability to walk, ability to perform normal work, relations with others, sleep, and enjoyment of life). Responses for the mBPI-sf items are captured through the use of 11-point numeric rating scales anchored at 0 (no pain or does not interfere) and ranged through 10 (pain as bad as you can imagine or completely interferes). The mBPI-sf recall period is 24 hours, and typical completion time for this instrument is less than 5 minutes.

    No participants were enrolled to stage 2; however, results for stage 2 outcomes are reported from the data collected for participants enrolled to stage 1.

  11. Stage 2: Change From Baseline in Symptom Burden on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30)

    Time frame: Baseline, 6 Months

    The EORTC QLQ-C30 self-reported general cancer instrument consists of 30 items covered by 1 of 3 dimensions:

    • Global health status/quality of life (2 items) with scores ranging from 1 (Very Poor) to 7 (Excellent).
    • Functional scales (15 total items addressing either physical, role, emotional, cognitive, or social functioning), each item scores ranging from 1 (not at all) to 4 (very much)
    • Symptom scales (13 total items addressing either fatigue, nausea/vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, or financial impact), each item scores ranging from 1 (not at all) to 4 (very much).

    Raw scores are linearly converted to a 0-100 scale with higher scores reflecting higher levels of function/QOL or higher levels of symptom burden.

    No participants were enrolled to stage 2; however, results for stage 2 outcomes are reported from the data collected for participants enrolled to stage 1.

  12. Stage 1: PK: Steady State Trough Pre Dose Concentration of LY3023414

    Time frame: C2D1: 0h, C3D1: 0h, C4D1: 0h

    Mean steady state exposure was reported by trough pre-dose plasma concentrations.

  13. Stage 1: PK: Mean Single Dose Concentration of LY3023414 at 2h Post-dose

    Time frame: C1D1: 2h Post dose

    Mean single dose exposure was reported by plasma concentrations collected approximately 2 hours post-dose.
