简要总结
Phase 1, open label, single center, dose escalation study to evaluate the safety, tolerability and pharmacokinetic profile of dMAb-ZK190 following delivery of INO-A002 with Hylenex® recombinant delivered IM followed by EP in healthy adult Dengue naïve volunteers ages 18-60 years.
详细描述
This is a Phase 1, open label, single center, dose escalation study to evaluate the safety, tolerability and pharmacokinetic profile of dMAb-ZK190 following delivery of INO-A002 with Hylenex® recombinant delivered IM followed by EP in healthy adult Dengue naïve volunteers ages 18-60 years.
The study will apply a 3+3 design such that 3 additional subjects will be enrolled into the cohort if one DLT (Section 7.3.1) is observed in one out of the first 3 subjects dosed during the 28-day period of safety and PK assessment. If no additional DLT is observed in 3 additional subjects (i.e., 1 DLT in 6 total subjects), dosing will proceed to the subsequent cohort. However, if any additional DLT occurs (i.e., >1 DLT in 6 total subjects), then that dose will be deemed not tolerated and the prior dose will be considered the maximum tolerated dose (MTD).

排除标准
- •Administration of an investigational compound either currently or within 30 days of first dose;
- •Previous receipt of an investigational product for the treatment or prevention of Zika virus except if participant is verified to have received placebo;
- •Administration of any vaccine within 4 weeks of first dose;
- •Administration of any monoclonal or polyclonal antibody product within 4 weeks of the first dose
- •Administration of any blood product within 3 months of first dose;
- •Pregnancy or breast feeding or plans to become pregnant during the course of the study;
- •Positive serologic result for dengue virus (any serotype) or history of receipt of either dengue virus or yellow fever virus vaccination at any time in the past;
- •Positive serologic test for hepatitis B surface antigen (HBsAg); or any potentially communicable infectious disease as determined by the Principal Investigator or Medical Monitor;
- •Positive serologic test for hepatitis C (exception: successful treatment with confirmation of sustained virologic response);
- •Baseline evidence of kidney disease as measured by creatinine greater than 1.5 (CKD Stage II or greater);
- •Baseline screening lab(s) with Grade 2 or higher abnormality, except for Grade 2 creatinine;
- •Chronic liver disease or cirrhosis;
- •Immunosuppressive illness including hematologic malignancy, history of solid organ or bone marrow transplantation;
- •Current or anticipated concomitant immunosuppressive therapy (excluding inhaled, topical skin and/or eye drop-containing corticosteroids, low-dose methotrexate, or prednisone at a dose greater than 10 mg/day or steroid dose-equivalent);
- •Current or anticipated treatment with TNF-α inhibitors such as infliximab, adalimumab, etanercept;
- •Prior major surgery or any radiation therapy within 4 weeks of group assignment;
- •Any pre-excitation syndromes, e.g., Wolff-Parkinson-White syndrome;
- •Presence of a cardiac pacemaker or automatic implantable cardioverter defibrillator (AICD)
- •Fewer than two acceptable sites available for IM injection and EP considering the deltoid and anterolateral quadriceps muscles. The following are unacceptable sites:
- •Tattoos, keloids or hypertrophic scars located within 2 cm of intended administration site;
- •Implantable-Cardioverter-defibrillator (ICD) or pacemaker (to prevent a life-threatening arrhythmia) that is located ipsilateral to the deltoid injection site (unless deemed acceptable by a cardiologist);
- •Any metal implants or implantable medical device within the electroporation site.
- •Prisoner or participants who are compulsorily detained (involuntary incarceration) for treatment of either a physical or psychiatric illness;
- •Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements or assessment of immunologic endpoints; or
- •Not willing to allow storage and future use of samples for Zika virus related research
- •Any illness or condition that in the opinion of the investigator may affect the safety of the participant or the evaluation of any study endpoint.
- •Participants who plan to travel within 6 months of INO-A002 administration to a geographic location where DENV or ZIKV are currently active.
- •Participants with known bleeding diatheses or that are using blood thinners for 30 days before study enrollment including warfarin, heparin, Clopidogrel, Apixaban (Eliquis), Dabigatran (Pradaxa), Edoxaban (Savaysa), Rivaroxaban (Xarelto). The use of low dose aspirin (81 mg daily) will be acceptable.
结局指标
主要结局
Determine the maximum serum concentration (Cmax) of the monoclonal antibody dMAb-ZK190 in the serum upon administration of INO-A002 with Hylenex® delivered IM followed by electroporation.
时间窗: 52 weeks
The maximum serum concentration (Cmax) assessment will be performed by the analysis of dMAb-ZK190 levels at baseline; days 1, 3, 7 and at weeks 2, 3, 4, 5, 6, 8, 12, 16, 24 and 52. Serum concentration in micrograms/mL will be used as the measurement scale.
Evaluate the safety of escalating doses of INO-A002 with Hylenex® administered IM followed by electroporation with the CELLECTRA® 2000 device in healthy adult volunteers.
时间窗: 52 weeks
Safety will be assessed by monitoring the frequency and severity of adverse events utilizing the "Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials" with labs assessed as per site normal values.
Evaluate the tolerability of escalating doses of INO-A002 with Hylenex® administered IM followed by electroporation with the CELLECTRA® 2000 device in healthy adult volunteers.
时间窗: 10 minutes
Pain will be assessed by administration (i.e., injection) site reactions (frequency and severity) and visual analogue scale (VAS) scores.
Determine the minimum serum concentration (Cmin) of the monoclonal antibody dMAb-ZK190 in the serum upon administration of INO-A002 with Hylenex® delivered IM followed by electroporation.
时间窗: 52 weeks
The minimum serum concentration (Cmin) assessment will be performed by the analysis of dMAb-ZK190 levels at baseline; days 1, 3, 7 and at weeks 2, 3, 4, 5, 6, 8, 12, 16, 24 and 52. Serum concentration in micrograms/mL will be used as the measurement scale.
Determine the Area Under the Curve (AUC0-t) of the monoclonal antibody dMAb-ZK190 in the serum upon administration of INO-A002 with Hylenex® delivered IM followed by electroporation
时间窗: 52 weeks
The Area Under the Curve (AUC0-t) will be performed by the analysis of dMAb-ZK190 levels at baseline; days 1, 3, 7 and at weeks 2, 3, 4, 5, 6, 8, 12, 16, 24 and 52. The Area Under the Curve (AUC0-t) against time will be calculated using the trapezoidal method.
