A Study of Safety, Tolerability and Immunogenicity of HPV-L2 Vaccine in Healthy Adult Male and Female Subjects

Study Description
Brief Summary:
The purpose of this study is to evaluate the safety, tolerability, and the immunological effects of adeno-associated virus-like particle human papillomavirus (AAVLP-HPV) vaccine in healthy adults.

Condition or disease Intervention/treatment Phase
Papillomavirus Infections Biological: AAVLP-HPV Drug: Placebo Phase 1

Detailed Description:

2A Pharma's AAVLP-HPV vaccine candidate is based on AAVLPs with insertion of sequences of the L2 minor HPV capsid protein. The vaccine's intended clinical use is as a vaccine for prophylaxis against HPV infection in adolescents and adults.

This is a 12 month single-center, randomized, placebo-controlled, double-blind, repeated dose, safety, tolerability, and immunological effect study. Twenty (20) healthy, adult male and female subjects will be enrolled with a minimum of 40% of each gender. Sixteen (16) subjects will be randomized to receive the active drug and 4 subjects to receive the placebo. At least 1 subject of each gender will be randomized to receive the placebo.

Subjects will receive a total of 3 doses of AAVLP-HPV or placebo: a prime on Day 1, and two boosts, one on Day 57 (±2 days) and one on Day 180 (±1 week). The volunteers will be followed until day 365 (±1 week) when they return for the final safety and serum-based immunogenicity and neutralising antibodies assessment.

Outcome Measures
Primary Outcome Measures :
  1. Percentage of Subjects Reporting Solicited Local Symptoms [ Time Frame: Day 0 and 1 after each vaccination ]
    Solicited local symptoms assessed including pain, tenderness, redness, swelling, and induration.

  2. Percentage of Subjects Reporting Solicited General Symptoms [ Time Frame: Through 365 days ]
    Solicited general symptoms assessed including fever, headache, fatigue, nausea, diarrhea, vomiting, myalgia, allergic reaction.

  3. Percentage of Subjects Reporting Unsolicited Adverse Events (AEs) [ Time Frame: Through 365 days ]
    An unsolicited adverse event is defined as any adverse event (AE) reported in addition to those solicited during the clinical study.

  4. Percentage of Subjects Reporting New Onset of Chronic Illness (NOCI) [ Time Frame: Through 365 days ]
    A NOCI is defined as diagnosis post study drug administration of a new medical condition, which is chronic in nature, including those potentially controllable by medication (e.g., diabetes, asthma)

  5. Percentage of Subjects Reporting Adverse Events of Special Interest (AESI) [ Time Frame: Through 365 days ]
    An AESI should not necessarily be classified to be a serious adverse event, even though the event may be clinically significant. If an AESI is reported, the Sponsor should be promptly informed and information relevant to the event should be promptly collected using the same process as that used for reporting serious adverse events. For this protocol, AESI includes demyelinating syndromes or neurological conditions such as complex regional pain or postural orthostatic tachycardia syndromes.

  6. Percentage of Subjects Reporting Serious Adverse Events (SAEs) [ Time Frame: Through 365 days ]
    SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above.

  7. Vital Signs - Body Temperature [ Time Frame: Through 365 days ]
    Single measurements of body temperature 35.6 ≤ Temperature ≤37.7 (C)

  8. Vital Signs - Respiratory Rate [ Time Frame: Through 365 days ]
    Measurements of respiratory rate 8≤ Respiration ≤24 (breaths/min)

    Measurements of blood pressure 90≤ Systolic ≤140 (mmHg) and 40≤ Diastolic ≤90 (mmHg

  10. Vital Signs - Heart Rate [ Time Frame: Through 365 days ]
    Measurements of 40≤ Pulse ≤99 (beats/min)

  11. Vital Signs - Body Mass Index (BMI [ Time Frame: Through 365 days ]
    Calculated as weight in kg / height in meters^2

  12. Electrocardiogram (ECG) [ Time Frame: Through 365 days ]
    Single 12-lead ECGs will be performed. Measurement type must be one of the following: HR (50≤HR≤100 [beats/min]], PR (110≤PR≤219 [ms]), QRS (QRS<110 [ms]), QT, QTcF (QTcF for Male<460 and for Female<470 [ms]), or overall interpretation.

  13. Physical examination [ Time Frame: Through 365 days ]
    A full best practice physical examination will be performed by the PI

  14. Clinical Laboratory Tests [ Time Frame: Through 365 days ]
    Measurements of clinical laboratory abnormalities


Secondary Outcome Measures :
  1. Evaluation of immunogenicity using a humoral immune function ELISA assay from serum [ Time Frame: Through 365 days ]
    Immunogenicity is measured as having generated anti-HPV type16 L2 and HPV type 31 L2 antibodies after vaccination. The antibody response is measured as a titer.

  2. Evaluation of HPV-Neutralizing Antibodies using an in vitro Pseudovirion-Based HPV-Neutralization Assay (PBNA) [ Time Frame: Through 365 days ]
    Neutralization is measured as having induced anti-HPV antibodies able to protect/neutralize HPV infection in vitro. The neutralization antibody titers are presented as the IC50 titer.
