Brief Summary

The objective of this Phase 1 trial is to assess the safety, tolerability and pharmacokinetics of AER-271 in health subjects.

Detailed Description

This is a double-blind, randomized, placebo-controlled, sequential-group study to assess the safety, tolerability and pharmacokinetics of single ascending dose and multiple ascending doses of intravenously (IV) administered AER-271 in healthy human subjects. AER-271 is an Aquaporin-4 inhibitor designed to prevent brain swelling in severe ischemic stroke. The study will be conducted in 2 parts: Part A is a single ascending dose, sequential group study. The subsequent Part B is a multiple ascending dose, sequential group study. Both Parts A and B will follow an adaptive design including the use of Sentinel Dosing.

The primary objectives of this study are to assess the safety and tolerability of single and multiple IV doses and continuous infusion of AER-271 in healthy subjects. Secondary objectives include: determining the pharmacokinetics of AER-271 and AER-270 following administration of AER-271, determining the dose proportionality for AER-270 and 271, and comparing the effects of continuous infusion versus multiple bolus doses on AER-271 exposure and adverse events. An additional exploratory objective of this study is to evaluate the effects of AER-271 on electrocardiogram parameters including QT interval corrected for heart rate. Data from this trial will also be used to develop a protocol for a subsequent Phase 2 clinical trial in stroke patients.

Study Groups

AER-271

The experimental drug AER-271 will be administered in this Arm. In Part A single ascending doses will be administered by IV bolus infusion of AER-271 formulated in phosphate buffered normal saline over a 30-min period. In Part B multiple ascending doses of AER-271 will be administered by IV 30-min bolus infusion BID for 72 hours. AER-271 will also be administered as an initial bolus dose over 30-min then continuous infusion over 72 hours.

Placebo

A placebo control will be administered in this Arm. In Part A phosphate buffered normal saline will be administered over a 30-min period. In Part B multiple doses of phosphate buffered normal saline will be administered by IV 30-min bolus infusion BID for 72 hours. This placebo will also be administered as an initial bolus dose over 30-min then continuous infusion over 72 hours. In both Parts, the volume of placebo administered will be the same as the Experimental Arm.

Eligibility Criteria

Inclusion Criteria

1. Males or females, of any ethnic origin, between 18 and 45 years of age, inclusive, at Screening.

2. Body mass index between 18.0 and 32.0 kg/m2, inclusive, at Screening.

3. In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital sign measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, suspected Gilbert's syndrome, as determined by total bilirubin and indirect bilirubin] is acceptable) at Screening and/or Check-in, as assessed by the Investigator.

4. Male subjects must be surgically sterile for at least 90 days or, for males capable of fathering children who are sexually active with female partners of childbearing potential, will use the required contraception methods, and will refrain from donating sperm from the time of the first dose until 90 days after the final dosing occasion.

5. Female subjects must be:

• postmenopausal, defined as at least 12 months post cessation of menses (without an alternative medical cause) with a screening serum follicle-stimulating hormone (FSH) level > 40 mIU/mL, or
• permanently sterile following hysterectomy, Essure procedure, bilateral salpingectomy, bilateral oophorectomy, or confirmed tubal occlusion (not tubal ligation).

6. Venous access sufficient for IV infusions.

7. Able to comprehend and willing to sign an Informed Consent Form (ICF) and to abide by the study restrictions.

Exclusion Criteria

1. Female subjects who are pregnant or lactating.

2. Have any clinically significant abnormal physical examination finding at Check-in.

3. Have any clinically significant medical history, as determined by the Investigator.

4. History of seizure disorder, even if currently not receiving anticonvulsant medications.

5. Part B only: Have acute suicidality, as evidenced by answering "yes" for Question 4 or Question 5 on the C-SSRS, indicating active suicidal ideation with any intent to act at Screening and Check-in.

6. Part B only: Have a history of suicidal behavior such that a determination of "yes" is made on the Suicidal Behavior section of the C-SSRS for "Actual Attempt," "Interrupted Attempt," "Aborted Attempt," or "Preparatory Acts or Behavior" at Screening and Check-in.

7. History or clinical manifestations of clinically significant metabolic (including diabetes mellitus, hypercholesterolemia, or dyslipidemia), hematologic, pulmonary, cardiovascular, gastrointestinal (cholecystectomy and appendectomy are acceptable), neurologic, hepatic, renal, urologic, immunologic, or psychiatric disorders (a history of mild depression, currently not receiving therapy, is acceptable), as determined by the Investigator.

8. Have any clinically significant allergic condition (excluding non-active hay fever), as determined by the Investigator.

9. Have a significant history of drug allergy, as determined by the Investigator.

10. Have a clinically significant abnormality in oral temperature, respiratory rate, or supine pulse rate or blood pressure at Screening and prior to first dose that, in the opinion of the Investigator, increases the risk of participating in the study.

11. Electrocardiogram findings that meet any of the following criteria at Screening or Day-1 (if out of range, ECG may be repeated twice, and the triplicate average will be used):

• QTcF >450 msec confirmed by repeat measurement,
• QRS duration > 120 msec,
• PR interval >220 msec,
• findings which would make QTc measurements difficult or QTc data uninterpretable.
