Clinical Trial Summary

Eligible male and female subjects with renal impairment (aged 18-78 years) and healthy control subjects (aged 35 to 78 years) will be enrolled in the study. Subjects with renal impairment will be enrolled and entered into three groups based on their renal function: Mild Impairment, Moderate Impairment, and Severe Impairment(not requiring dialysis). Control subjects will have normal renal function.

The screening visits will occur within 14 days prior to plerixafor administration on study day one. Subjects will be monitored for 10 hours following administration of the study drug. In addition, subjects will return to the clinic at 24 and 48 hours after plerixafor administration for blood samples and safety assessments.

Description:

This is a phase I, open label, multi-center study in which up to eighteen subjects with renal impairment and six healthy control subjects with normal renal function will receive a single dose of plerixafor (240 µg/kg) administered by subcutaneous (SC) injection.

Eligible male and female subjects with renal impairment (aged 18-78 years) and healthy control subjects (aged in the upper age range of the renal impairment subjects) will be enrolled in the study. Subjects with renal impairment will be enrolled and stratified into three cohorts using their Screening 24 hour urine collection to measured creatinine clearance (CLcr) values (an estimate of Glomerular Filtration Rate): Mild Impairment (CLcr = 51-80 ml/min), Moderate Impairment (CLcr = 31-50 ml/min), and Severe Impairment (CLcr <31 ml/min, not requiring dialysis). Control subjects will have normal renal function (CLcr >90 ml/min), as determined by a Screening 24 hour urine collection.

The screening visits will occur within 14 days prior to plerixafor administration on study day one. Subjects will be monitored for 10 hours following administration of the study drug. In addition, subjects will return to the clinic at 24 and 48 hours after plerixafor administration for blood samples and safety assessments.

Exclusion Criteria:

• Known sensitivity to plerixafor or any of its components.

• Pregnant or breast-feeding.

• Actual body weight exceeds 175% of ideal body mass index.

• Subjects judged by the investigator to be at significant risk of failing to comply with the requirements of the protocol.

• Any subject who has started new medication within 14 days prior to study drug administration.

• Treatment with an investigational product within 30 days prior to trial entry.

• Any significant untreated or newly diagnosed medical condition other than renal impairment that in the opinion of the investigator may interfere with the conduct of the study.

• Abnormal electrocardiogram with clinically significant rhythm disturbance,(ventricular arrhythmias), or other conduction abnormality that in the opinion of the investigator warrants exclusion of the subject from the trial.

• History of clinically significant thrombocytopenia.

• Received blood transfusions within 30 days prior to trial entry.

• Any subject who requires therapeutic intervention within the 30 days prior to administration of study medication in order to meet the inclusion/exclusion criteria.

• Active malignant/neoplastic disease requiring treatment of any kind.

• Active infection requiring antibiotics

• Renal impairment requiring any method of dialysis

• History of kidney transplant

• Subjects having clinical status or laboratory parameter deterioration between the time of enrollment and dosing with plerixafor (such that they no longer meet entry criteria) may be removed from the study at the discretion of the treating physician, principal investigator, or sponsor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose-Normalized Maximum Concentration of Plerixafor (Cmax)	Evaluation of Cmax following a single dose of 240 µg/kg plerixafor administered on Day 1. Cmax was normalized by dose.	Pre-dose of plerixafor to 24 hours post-plerixafor	No
Primary	Dose-Normalized Area Under the Plerixafor Concentration Time Curve From Time 0 to 24 Hours Post-dose (AUC0-24h)	Evaluation of AUC0-24 hour following a single dose of 240 µg/kg plerixafor administered on Day 1. AUC0-24 was normalized by dose.	Pre-dose of plerixafor to 24 hours post-plerixafor	No
Secondary	Change From Baseline in Absolute CD34+ Cell Counts at Day 2	Change in circulating CD34+ cells from baseline to Day 2 (24 hours post-plerixafor) following a single dose of plerixafor. Change from baseline = CD34+ cell count at 24 hours post dose - CD34+ cell count at Baseline.	Baseline, Day 2	No
Secondary	Change From Baseline in Absolute White Blood Cell (WBC) Counts at Day 2	Change in absolute white blood cells from baseline to Day 2 (24 hours post-plerixafor) following a single dose of plerixafor. Change from baseline = absolute white blood cells at 24 hours post dose - absolute white blood cells at Baseline.	Baseline and Day 2	No
Secondary	Number of Participants in Overall Safety Summary of Adverse Events (TEAE)	Number of participants with adverse events (AEs) collected from Day 1 (post plerixafor administration) to Day 3. AEs were graded by the investigator using the World Health Organization (WHO) Adverse Event Grading Scale and were assessed for severity (mild, moderate, severe, life-threatening) and relatedness to study treatment (5 point scale from 'not related' to 'definitely related').	up to Day 3	Yes
