Clinical Trial to Evaluate the Safety and Analgesic Efficacy of VVZ-149 in Lumbar Radiculopathy (Sciatica)

Completed · Phase 1 · Has a placebo group

Conditions studied: Radiculopathy, Sciatica

In brief

Double-blind, crossover, randomized, 3x3 Latin square, placebo-controlled study of single intravenous dose administration of VVZ-149. To demonstrate assay sensitivity, lidocaine will be administered as a positive control. The study will take place during a single inpatient visit involving three separate treatment periods, each with a washout of (\>16-hours. Study drugs (VVZ-149 vs. lidocaine vs. normal saline, NS) will be administered intravenously.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects must have a history of persistent pain secondary to unilateral monoradiculopathy present for a minimum of 3 months prior to the study, with an average pain intensity score of at least moderate over at least 50% of the day for the 7 days prior to the screening visit and over the 7 days prior to starting study medication.
• Males or females between 18 and 70 years of age, inclusive. Females who are pregnant or breastfeeding will be excluded from the trial.
• Subjects must be in generally good health, either using no medication or using a stabilized medication regimen for chronic and well-controlled conditions such as hypertension, allergies, stable endocrinopathies (e.g. hypothyroidism), etc. Subjects with other active diseases will be reviewed on a case-by-case basis by the principal investigator.
• No concomitant therapy with any medication that is a known significant inhibitor or inducer of CYP450 2D6 and CYP3A4, at the discretion of the PI.
• Normal or clinically insignificant screening laboratory tests:
• Serum BUN, creatinine, bicarbonate, calcium, chloride, potassium, sodium, lactate dehydrogenase, inorganic phosphate, total protein, glucose, albumin, and uric acid. WBC, absolute neutrophil count, hemoglobin, hematocrit, and platelets. SGOT (AST), SGPT (ALT), total bilirubin, alkaline phosphatase, TSH/T4, urinalysis, and urine toxicology screen.
• Electrocardiogram (12-lead). Any significant laboratory abnormalities will be reviewed by the principal investigator prior to inclusion of the subject in the study.
• Willingness to restrict analgesic therapy during inpatient admission days to the allowed rescue analgesic agent permitted by the study (acetaminophen).
• Subjects must have normal cognitive function and communicative ability in the English language.
• Subjects must be able to provide meaningful written informed consent.
• Subjects must be able to maintain complete required questionnaires, and must be able to fulfill all other conditions of the protocol.

• Subjects with a previous history of multiple or severe drug allergies, including lidocaine.
• Subjects with a history of or current chronic substance abuse, including alcohol.
• Subjects who have participated in a study of an investigational drug or device within 30 days prior to screening for this study. Subjects must agree not to participate in other investigational drug or device studies during the entire course of this study (beginning with the screening visit).
• Subjects with the following abnormal clinical evaluations:
• Impaired renal function defined as BUN > 45 or creatinine >2.0 and/or impaired liver function defined as liver transaminases, alkaline phosphatase, or bilirubin greater than 1.5 x upper limit of normal laboratory values.
• Prolonged PR (>200 ms) interval on electrocardiogram (12-lead). Subjects presenting with the above laboratory abnormalities may be allowed on a case-by-case basis at the discretion of the principal investigator.
• Subjects who intend to donate blood or blood products while participating in this study, and for 30 days following completion of the study.
• Subjects with clinically significant renal, hepatic, or cardiac disease, with seizure disorders, or with a clinical history of life-threatening arrhythmias (i.e. torsades de pointes).
• Subjects with a severe neuropsychiatric disorder requiring treatment.
• Subjects with sensitivity to amide-type local anesthetics.
