Efficacy and Safety of Nicotine-Qbeta Vaccine in Smokers
A Phase 2 study testing CYT002-NicQb in people with Smokers, run by Cytos Biotechnology AG at 3 sites in Switzerland.
Trial summary
The purpose of this study is to help smokers quitting by vaccinating them with CYT002-NicQb. Upon vaccination, the smoker will generate antibodies directed against free nicotine. The antibodies will bind nicotine and prevent its passage into the brain. Read more about this study

About this study
Official title: Evaluation of Efficacy and Safety of Nicotine-Qbeta (NicQb) Vaccine Versus Placebo in Healthy Smokers
The purpose of this study is to help smokers quitting by vaccinating them with CYT002-NicQb. Upon vaccination, the smoker will generate antibodies directed against free nicotine. The antibodies will bind nicotine and prevent its passage into the brain. The successfully vaccinated smoker will have no reward effect after smoking, thus braking the vicious circle of nicotine addiction.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CYT002-NicQbBiological
| Study group | Role | What they receive |
|---|---|---|
| NicQb vaccine | Experimental | Not described Receives: Biological: CYT002-NicQb |
| Placebo vaccine | Placebo comparator | Not described Receives: Biological: CYT002-NicQb |
What is being measured
The primary outcome is the main question the study is designed to answer.
Abstinence from smoking defined as self-reported abstinence and confirmed by measurement of carbon monoxide in exhaled air less than 10ppm
Measured: Monthly up to month 6, and during follow-up at months 9 and 12
Immunogenicity of the vaccine, by measuring specific anti-nicotine IgG antibodies by ELISA
Measured: Baseline, monthly up to month 6, and months 9 and 12
Safety and tolerability by recording adverse events, injection site examinations, vital signs, standard clinical laboratory (serum chemistry, hematology)
Measured: Baseline, and at various times up to month 12
Secondary outcomes (1)
Craving and withdrawal symptoms by Questionnaire on Smoking Urges and Wisconsin Withdrawal Scale
Measured: Baseline, monthly up to month 6

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing CYT002-NicQb in people with Smokers, run by Cytos Biotechnology AG at 3 sites in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Abstinence from smoking defined as self-reported abstinence and confirmed by measurement of carbon monoxide in exhaled air less than 10ppm (time frame: Monthly up to month 6, and during follow-up at months 9 and 12). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00369616, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Nov 2010.
