Anticancer Activity of Nicotinamide on Lung Cancer
A Phase 2/3 study testing Nicotinamide in people with Non-Small-Cell Lung Carcinoma, run by Il Yeong Park, Ph.D. at 1 site in South Korea.
Trial summary
Nicotinamide is an inhibitor of human sirtuins (HDAC III), and is found to re-activate epigenetically silenced tumor suppressors, RUNX3 (runt-related gene 3) and others, in cancer cells. Nicotinamide was found to be effective in several animal cancer models including lung, bladder, liver, etc. Read more about this study

About this study
Official title: Randomized Double-blinded Comparative Trial to Study the Add-on Activity of Combination Treatment of Nicotinamide on Progression Free Survival for EGFR Mutated Lung Cancer Terminal Stage Patients Being Treated With Gefitinib or Erlotinib
Nicotinamide is an inhibitor of human sirtuins (HDAC III), and is found to re-activate epigenetically silenced tumor suppressors, RUNX3 (runt-related gene 3) and others, in cancer cells. Nicotinamide was found to be effective in several animal cancer models including lung, bladder, liver, etc. The purpose of this study is to determine whether nicotinamide is also effective in the treatment of human lung cancer.
Read the detailed description
The standard therapy to the EGFR (epidermal growth factor receptor) mutation positive non-small-cell lung cancer patients who are not eligible to operation is to administer EGFR-TKIs (tyrosine kinase inhibitors, gefitinib or erlotinib). To determine the effectiveness of nicotinamide on lung cancer, nicotinamide or placebo tablet will be co-administered with gefitinib or erlotinib for two years until the event or censoring occurs. The stratified block randomization was designed with 3 covariates (EGFR mutation status, kind of EGFR-TKI, ECOG (Eastern Cooperative Oncology Group) performance status score variation). The size of lesions will be checked every other months by radiology. PD (progressive disease) will be assessed according to RECIST(Response Evaluation Criteria in Solid Tumors)1.1. After observing 36 events, an interim analysis of hazard ratio by Cox proportional hazard regression will be performed. The final analysis will be done by the same protocol after observation of 72 events. The significance level of the interim and final analysis were set to 0.0075 and 0.0209 respectively. Response rate, quality of life (measured by 10 questions at every visit), and overall survival will be analysed together. All other adverse reactions will be analysed and reported, if there.

Nicotinamide is an inhibitor of human sirtuins (HDAC III), and is found to re-activate epigenetically silenced tumor suppressors, RUNX3 (runt-related gene 3) and others, in cancer cells. Nicotinamide was found to be effective in several animal cancer models including lung, bladder, liver, etc. The purpose of this study is to determine whether nicotinamide is also effective in the treatment of human lung cancer.
Detailed description

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Nicotinamide in people with Non-Small-Cell Lung Carcinoma, run by Il Yeong Park, Ph.D. at 1 site in South Korea.
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 6 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 27 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. 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 combined 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.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Hazard ratio (PFS) of the nicotinamide arm to the placebo arm (time frame: two year). 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 NCT02416739, which also lists 18 linked publications.
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 27 Jan 2020.
