Brief summary
Study E7389-E044-112 is a Phase 1 study designed to assess the safety, tolerability and preliminary efficacy of eribulin-liposomal formulation (E7389-LF) in patients with solid tumors. This dose-escalation study will determine the maximum tolerated dose, dosing schedules tested, the dose schedule regimen with a more favorable tolerability profile, and a preliminary indication of efficacy.
Detailed description
This is a Phase 1 first-in-human, non-randomized (individuals will not be assigned by chance to study treatments), open-label (individuals will know the identity of study treatments), multicenter, 2-part, dose-escalation study to evaluate the safety, pharmacokinetics (study of what the body does to a drug) of eribulin-LF administered intravenously to patients with solid tumors. Each treatment cycle will be 21 days (Schedule 1) or 28 days (Schedule 1a or 2). Part 1 is the dose-escalation phase, which will be guided by pharmacokinetics and safety. Three to 6 new patients will be enrolled in sequential cohorts (first cohort will receive the starting dose and subsequent cohorts will receive increased doses of eribulin-LF). Enrollment in each cohort will be staggered; the second and third participant in every cohort will not be dosed until the first patient in that cohort completes 2 weeks of Cycle 1. If no dose-limiting toxicities (DLTs) have been observed during the first 2 week of Cycle 1 in the first patient, the second and third patients in the cohort will initiate treatment. Enrollment will be first initiated into cohort 1 of Schedule 1 (dosing on Day 1 of 21 day cycle). Interim analysis will be conducted upon completion of this cohort. The following decisions will be made based upon the results of the interim analysis 1) proceed with escalating to next dose level (cohort 2) of Schedule 1 (dosing on Day 1 of 21 day cycle) and initiate cohort 1 of Schedule 2 (dosing on Day 1 and Day 15 of 28 day cycle), or 2) discontinue plans to evaluate Schedule 2 and initiate Schedule 1a (dosing on Day 1 of 28 day cycle). After the last patient in each cohort completes Cycle 1, the safety for DLT determination will be evaluated and a decision will be made on whether to escalate the dose in a new cohort of 3 to 6 new patients. Dose escalation will halt when the maximum tolerated dose (MTD) is reached. The total number of patients to be enrolled in Part 1 will depend on the dose level at which the DLT will be achieved. After MTD for each schedule is determined, patients will be enrolled into Expansion Part of the study to confirm safety and tolerability of each dosing schedule. Nine to 12 patients will be treated with MTD for each schedule for 6 cycles. The total study duration for each participant will be approximately 18 months.

CR was defined as disappearance of all target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in short axis to less than 10 mm. PR was defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters. The null hypothesis ORR was less than or equal to 10% was tested using 1-sided exact test of a single proportion, at 1-sided 0.05 level.

The minimum duration of SD was defined as 5 weeks (or 7 weeks for Schedules 1a and 2 in the Dose Escalation Part) following the date of the first dose of study drug in order for stable disease to be considered the best overall response. The 95% CI was constructed using the method of Clopper and Pearson. DCR = CR + PR + SD |
| Percentage of Participants With Clinical Benefit Rate (CBR) | From date of treatment start until disease progression, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment, or up to data cutoff date (17 May 2016), for up to approximately 3 years 7 months | CBR was defined as the percentage of participants with BOR of CR or PR or durable stable disease (dSD) \[CR + PR + dSD\] based on RECIST v1.1. The dSD rate was defined as the percentage of participants with dSD (based on RECIST 1.1 and defined as SD lasting greater than or equal to 6 months), as determined by the site Investigator. |
| Percentage of Participants With Progression Free Survival (PFS) | From date of treatment start until disease progression, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment, or up to data cutoff date (17 May 2016), for up to approximately 3 years 7 months | PFS was defined as the time from the date of treatment start until progressive disease or death from any cause in the absence of progressive disease. Disease progression was defined as at least a 20% increase in the sum of the longest diameter of target lesions (taking as reference the smallest sum on study), recorded since the treatment started or the appearance of 1 or more new lesions as assessed by IRR using RECIST v1.1. The duration of PFS was calculated as end date minus date of first drug plus 1, based on assessments by the site Investigator. PFS was calculated using Kaplan-Meier estimate and presented with 2-sided 95% Cl. |
| Number of Participants With the Indicated Shift From Baseline Category to the Indicated Worst Post-Baseline Category | Baseline (Day -1), Schedule 1 (Cycle 1 Day 1); Schedule 2 (Cycle 1 Day 1 and Day 15) | The effects of eribulin-LF on cardiovascular repolarization were evaluated via 24-hour, 12-lead continuous Holter electrocardiogram (ECG) monitoring in Cycle 1, Day 1 for Schedule 1 and Day 1 and Day 15 of Schedule 2. Individual ECGs were extracted in triplicate from the Holter recordings at specified time points and were evaluated by a central laboratory. QT intervals were measured from Lead II and were corrected for heart rate (QTc) using Fridericia's (QTcF) and Bazett's (QTcB) correction factors. The primary QTc parameter was QTcF. Secondary parameters (QTcB, QT, QRS, and hazard ratio/heart rate (HR)) and waveforms (T-waves) were evaluated. BL= Baseline, PBL = post-Baseline, A,NCS = abnormal, not clinically significant, A, CS = abnormal, clinically significant |
| Fraction of Unchanged Eribulin-LF Excreted in the Urine (fe) | Schedule 1: Cycle 1/Day 1 and Cycle 3/Day 1; Schedule 2: Cycle 1/Day 1 and Day 15 and Cycle 3/Day 1 and Day 15 | Urinalysis was performed at Screening, Baseline, Cycle 1/Day 15, and each study visit of every cycle thereafter. If urinalysis suggested a urinary tract infection, or if clinically indicated, a urine microscopy, culture, and sensitivity was to be performed at the institution's laboratory. If urine protein was ≥ 2+ on urinalysis, then a 24-hour urine collection was to be done to quantify the 24-hour urine protein excretion. The samples were analyzed for the amount of eribulin in the urine using liquid LC/MS method of analysis. Urine PK data were analyzed using a noncompartmental analysis approach to obtain individual participant estimates of fe, which was then summarized as the mean and standard deviation for all participants and expressed in percentage of eribulin-LF. |
| Maximum Plasma Concentration (Cmax) of Eribulin-LF | Schedule 1: Cycle 1/Day 1 and Cycle 3/Day 1; Schedule 2: Cycle 1/Day 1 and Day 15 and Cycle 3/Day 1 and Day 15 | Blood samples for Schedule 1 were drawn on Cycle 1/Day 1 and Cycle 3/Day 1 predose, 15 minutes (min) after the start of infusion (SOI), 5 min after the end of infusion (EOI), 0.5, 1, 2, 4, 6, 8, and 24 hours (h) postdose, and Day 4, Day 7, Day 9, and Day 11. Blood samples for Schedule 2 were drawn on Cycle 1/Day 1 and Day 15 and Cycle 3/Day 1 and Day 15 predose, 15 min after the SOI, 5 min after the EOI, 0.5, 1, 2, 4, 6, 8, and 24 h postdose, and Day 4, Day 7, Day 9 and Day 11. Some participants followed a different pharmacokinetic (PK) assessment schedule prior to protocol amendment 3. Plasma concentrations of eribulin-LF were determined using a validated liquid chromatography-tandem mass spectrometry (LC/MS/MS) method. Plasma PK data were analyzed using a noncompartmental analysis approach to obtain individual participant estimates of Cmax, which was then summarized as the mean and standard deviation for all participants and expressed as nanograms/milliliter (ng/mL). |

Dose Limiting Toxicities at the Indicated Dose Levels, as an Assessment of Dosing Frequency
DLTs were evaluated for both Schedule 1 and Schedule 2. DLTs were defined as neutropenia grade 4 that lasted more than 5 days, neutropenia grade 3 or 4 complicated by fever and/or infection (absolute neutrophil count (ANC) less than 1.0 x 10\^9/liter, fever greater than or equal to 38.5 degrees Celsius), thrombocytopenia grade 4 of any duration, thrombocytopenia grade 3 complicated by bleeding and/or requiring platelet or blood transfusion, hypersensitivity reaction grade 3 or 4 including allergy reactions or anaphylaxis; symptomatic bronchospasm requiring parenteral medication(s) with our without urticarial; allergy-related edema/angioedema, or other grade 3 or 4 clinically significant non-hematologic toxicities (except for inadequately treated nausea and /or vomiting) considered related to study drug. Participants with two or more adverse events in the same system organ class (or with the same preferred term) was counted only once for that system organ class (or preferred term).
Time frame: Cycle 1 of Dose Escalation part in Schedule 1 and Schedule 2
Population: Dose-finding analysis set included all participants in the dose escalation part who completed Cycle 1 treatment and were evaluated for DLTs and those who discontinued during Cycle 1 due to DLTs.

Maximum Tolerated Dose (MTD) of Eribulin-LF
The MTD was defined as the highest dose level at which no more than 1/6 participants experienced a dose limiting toxicity (DLTs), with the next higher dose having at least 2 of 3 or 2 of 6 participants experiencing DLTs. MTD was determined by summarizing the number and percentage of participants with DLTs for the first cycle, by study dosing schedule, initial dosing level and overall for the dose escalation part. For participants who continued to Cycle 2, the DLTs which occurred from 1st dose up to the day before Day 1 of Cycle 2 were counted. For participants who discontinued before Cycle 2, the DLTs which occurred from 1st dose up to Day 21 (Schedule 1) or Day 28 (Schedule 2) of Cycle 1 were counted. DLTs were evaluated and graded based on the National Cancer Institutes (NCI)'s Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.
Time frame: Schedule 1: Cycle 1 (21 days); Schedule 2: Cycle 1 (28 days)
Population: Dose finding analysis set is all participants in the dose escalation part who completed Cycle 1 treatment and were evaluated for DLTs, and those who discontinued during Cycle 1 due to DLT.

Fraction of Unchanged Eribulin-LF Excreted in the Urine (fe)
Urinalysis was performed at Screening, Baseline, Cycle 1/Day 15, and each study visit of every cycle thereafter. If urinalysis suggested a urinary tract infection, or if clinically indicated, a urine microscopy, culture, and sensitivity was to be performed at the institution's laboratory. If urine protein was ≥ 2+ on urinalysis, then a 24-hour urine collection was to be done to quantify the 24-hour urine protein excretion. The samples were analyzed for the amount of eribulin in the urine using liquid LC/MS method of analysis. Urine PK data were analyzed using a noncompartmental analysis approach to obtain individual participant estimates of fe, which was then summarized as the mean and standard deviation for all participants and expressed in percentage of eribulin-LF.

Number of Participants With the Indicated Shift From Baseline Category to the Indicated Worst Post-Baseline Category
The effects of eribulin-LF on cardiovascular repolarization were evaluated via 24-hour, 12-lead continuous Holter electrocardiogram (ECG) monitoring in Cycle 1, Day 1 for Schedule 1 and Day 1 and Day 15 of Schedule 2. Individual ECGs were extracted in triplicate from the Holter recordings at specified time points and were evaluated by a central laboratory. QT intervals were measured from Lead II and were corrected for heart rate (QTc) using Fridericia's (QTcF) and Bazett's (QTcB) correction factors. The primary QTc parameter was QTcF. Secondary parameters (QTcB, QT, QRS, and hazard ratio/heart rate (HR)) and waveforms (T-waves) were evaluated.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) as a Measure of Safety and Tolerability of Eribulin-LF
Safety was assessed by the monitoring and recording of all adverse events (AEs), and serious AEs (SAEs), regular monitoring of hematology, clinical chemistry, and urine values; periodic measurement of vital signs, electrocardiograms; and the performance of physical examinations. For each row category, a participant with two or more adverse events in that category is counted only once. Treatment-related TEAEs include TEAEs that were considered by the Investigator to be possibly or probably related to study drug and TEAEs with a missing relationship to study drug.
Time frame: From date of first dose until 30 days after the final dose of study drug, up to approximately 3 years 6 months
Population: The SAS was the group of participants who received study drug and had at least 1 post-dose safety assessment.

Percentage of Participants With Best Overall Response (BOR)
BOR to treatment was assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. BOR was the best confirmed response of complete response (CR), partial response (PR), progressive disease (PD), stable disease (SD), or not evaluable (NE), recorded from the start of eribulin-LF until disease progression/recurrence or death. CR; disappearance of all target lesions for at least 1 month. PR; at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD; at least 20% or greater increase in the sum of the longest diameter of measured lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of one or more new lesions. SD; PR failed to be achieved in the overall response assessment and there was no PD observed at the end of 6 cycles or later after starting eribulin-LF.
Time frame: Baseline to first date of documented CR, PR, SD, or PD, assessed up to data cutoff date (17 May 2016), for up to approximately 3 years 7 months
Population: The SAS was the group of participants who received study drug and had at least 1 post-dose safety assessment.

Percentage of Participants With Disease Control Rate (DCR)
DCR was the percentage of the participants who had BOR of CR, PR, and SD, based on assessments by each site investigator using RECIST v1.1. The minimum duration of SD was defined as 5 weeks (or 7 weeks for Schedules 1a and 2 in the Dose Escalation Part) following the date of the first dose of study drug in order for stable disease to be considered the best overall response. The 95% CI was constructed using the method of Clopper and Pearson. DCR = CR + PR + SD
Time frame: From date of treatment start until disease progression, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment, or up to data cutoff date (17 May 2016), for up to approximately 3 years 7 months
Population: The SAS was the group of participants who received study drug and had at least 1 post-dose safety assessment.

Percentage of Participants With Objective Response Rate (ORR)
ORR was defined as the percentage of participants with BOR of CR or PR based on RECIST v1.1 criteria or target lesions assessed by magnetic resonance imaging/computed tomography (MRI/CT) scans, as determined by independent radiologic review. BOR of CR was confirmed by a subsequent CR assessment at least 4 weeks later. BOR of PR was confirmed by a subsequent CR or PR assessment at least 4 weeks later. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in short axis to less than 10 mm. PR was defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters. The null hypothesis ORR was less than or equal to 10% was tested using 1-sided exact test of a single proportion, at 1-sided 0.05 level. ORR was presented with corresponding 2-sided, 95% confidence interval (CI). ORR=CR+PR.

Percentage of Participants With Progression Free Survival (PFS)
PFS was defined as the time from the date of treatment start until progressive disease or death from any cause in the absence of progressive disease. Disease progression was defined as at least a 20% increase in the sum of the longest diameter of target lesions (taking as reference the smallest sum on study), recorded since the treatment started or the appearance of 1 or more new lesions as assessed by IRR using RECIST v1.1. The duration of PFS was calculated as end date minus date of first drug plus 1, based on assessments by the site Investigator. PFS was calculated using Kaplan-Meier estimate and presented with 2-sided 95% Cl.
Time frame: From date of treatment start until disease progression, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment, or up to data cutoff date (17 May 2016), for up to approximately 3 years 7 months
Population: PFS data was not collected as this is a Phase I dose escalation design and was not the focus of the study.
