Improving the Efficacy of Anti-Nicotine Immunotherapy (PETNic002)

The purpose of this study is to find out how vaccine-induced antibodies change the way the body processes nicotine from cigarettes. These antibodies absorb nicotine and can reduce nicotine levels in the brain. In this way, the vaccination may help to quit smoking. The central hypothesis is that anti-nicotine antibodies change kinetics of brain nicotine accumulation and distribution of nicotine between the brain and other body tissues. This vaccine is investigational which means that it is still being tested in research studies and is not approved by the U.S. Food and Drug Administration (FDA) to help people quit smoking.

11. Active ulcers in the past 30 days;
12. Lung disorder (including but not limited to chronic obstructive pulmonary disease (COPD), emphysema, and asthma);
13. Brain abnormality or other neurological disorder (including but not limited to stroke, brain tumor, and seizure disorder);
14. Recent, unexplained fainting spells;
15. Problems giving blood samples;
16. Diabetes treated with insulin; non-insulin treated diabetes (unless glucose is less than 180mg/dcl and HbA1c is less than 7%);
17. Current cancer or treatment for cancer in the past six months (except basal or squamous cell skin cancer);
18. Skin disorder;
19. Autoimmune disease;
20. Human immunodeficiency virus (HIV) or HIV risk behavior;

22. Other major medical condition;
23. Current psychiatric disease including major depressive episode, panic attack, psychosis, bipolar disorder or eating disorder;
24. Pregnant or nursing mothers;

25. Use (within the past 30 days) of:

    • Illegal drugs (or if the urine drug screen is positive),
    • Experimental (investigational) drugs;
    • Psychiatric medications including antidepressants, anti-psychotics or any other medications that are known to affect smoking cessation (e.g. clonidine);
    • Opiate medications for pain or sleep (non-opiate medication for pain or sleep will be allowed)
    • Smokeless tobacco (chewing tobacco, snuff), cigars, pipes or e-cigarettes;
    • Nicotine replacement therapy or any other smoking cessation aid.
26. Alcohol abuse - The AUDIT (Alcohol Use Disorders Identification Test) questionnaire will be used to assess alcohol abuse.
27. Previous history of negative experiences with "flu" vaccine or any other vaccine.
28. High chronic exposure to aluminum (occupational or medical);

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: NIC002 Vaccine in Aluminum hydroxide; 4 subcutaneous vaccinations were performed over the course of 3 months, with 4 weeks between each vaccination. The administered volume of 0.65 mL of sterile water contained 100 μg of NIC002 and 0.46 mg aluminum hydroxide.	Biological: NIC002 in Aluminum hydroxide (Alum); Fifty-five subjects will receive 4 subcutaneous injections of 0.1 mg Nicotine-QB (NIC002) in Alum vaccine with a 4-week interval between injections.; Other Names: CYT002-NicQb (Nicotine-Qbeta); Anti-Nicotine Vaccine
Placebo Comparator: Placebo Vaccine - Aluminum hydroxide; 4 placebo injections were administered subcutaneously over the course of 3 months, with 4 weeks between each vaccination. The administered volume of 0.65 mL of sterile water contained 0.46 mg aluminum hydroxide.	Biological: Placebo Vaccine - Aluminum hydroxide; Ten subjects will receive 4 subcutaneous injections of indistinguishable placebo (Alum alone) with a 4-week interval between injections.
