Summary

The primary aim of this Phase 1 study is to evaluate the systemic safety of a novel prolonged-duration local anesthetic, Neosaxitoxin (NeoSTX), given by subcutaneous injection in combination with the commonly used local anesthetic, bupivacaine, and epinephrine.

The investigators hypothesize that a "minimal adverse effect threshold" NeoSTX dose for subcutaneous administration in combination with bupivacaine 0.2% and epinephrine 5mcg/ml respectively, can be defined for awake, young adult healthy volunteer subjects. At the same time, the pharmacokinetics of NeoSTX when delivered subcutaneously will be determined.

Conditions

  • Safety of Neosaxitoxin in Healthy Volunteers

Interventions

DRUG

Neosaxitoxin in saline

NeoSTX will be administered in sequential dose cohorts. Each subject receives one injection with bupivacaine 0.2% alone on one side (control). On the other side they receive NeoSTX in saline (test). Subjects receive NeoSTX in saline in subsequent dose escalation levels: 5 mcg, 10 mcg, 15 mcg, 20 mcg, 30 mcg, and 40 mcg of NeoSTX.

DRUG

NeoSTX + bupivacaine 0.2%

NeoSTX will be administered in sequential dose cohorts. Each subject receives one injection with bupivacaine 0.2% on one side (control). On the other side they receive NeoSTX with 0.2% bupivacaine. Subjects receive NeoSTX in 0.2% bupivacaine in subsequent dose escalation levels: 5 mcg, 10 mcg, 15 mcg, 20 mcg, 30 mcg, and 40 mcg of NeoSTX.

DRUG

NeoSTX + bupivacaine 0.2% + epinephrine 5mcg/ml

Each subject receives one injection with bupivacaine 0.2% on one side (control). On the other side they receive NeoSTX in 0.2% bupivacaine with epinephrine 5 mcg/ml. Subjects receive NeoSTX in 0.2% bupivacaine with epinephrine 5 mcg/ml in doses of 10 mcg or 30 mcg of NeoSTX.

OTHER

Saline placebo

Each subject receives one injection with bupivacaine 0.2% alone on one side. On the other side they receive saline placebo.
