Therapeutic Efficacy of Quercetin Versus Its Encapsulated Nanoparticle on Tongue Squamous Cell Carcinoma Cell Line
Study Purpose
Squamous cell carcinoma (SCC) is the most common oral cavity carcinoma. Conventional therapeutic modalities for oral malignancy include surgery, radiotherapy and chemotherapy alone or in combinations.The major obstacle of using current anticancer drugs is; first the non-specific tissue distribution, as these drugs are unable to distinguish between normal and cancer cells.Quercetin is a bioactive flavonoid having strong antioxidant properties. .Among all the nanomaterials, polymeric nanoparticles are of significant interest for drug delivery applications due to many unique features of nanoparticle polymers.This is the first study to investigate the anticancer effects of (Quercetin) either free or encapsulated by PLGA-PEG NPs in tongue squamous cell carcinoma (TSCC) cell line.
Recruitment Criteria
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
Inclusion Criteria:
Exclusion Criteria:
- - Any use of Quercetin other than chemotherapy.
- Detection of Quercetin activities other than apoptosis or cytotoxicity/cell viabilityTrial Details
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.
Category of organization(s) involved as sponsor (and collaborator) supporting the trial.
The disease, disorder, syndrome, illness, or injury that is being studied.
Squamous cell carcinoma (SCC) is the most common oral cavity carcinoma. Conventional therapeutic modalities for oral malignancy include surgery, radiotherapy and chemotherapy alone or in combinations. The major obstacle of using current anticancer drugs is; first the non-specific tissue distribution, as these drugs are unable to distinguish between normal and cancer cells. Quercetin is a bioactive flavonoid having strong antioxidant properties. It is naturally present in a wide variety of fruits and vegetables. Among all the nanomaterials, polymeric nanoparticles are of significant interest for drug delivery applications due to many unique features of nanoparticle polymers. Polymeric nanocarriers have been fabricated from natural and synthetic polymers. Poly ethylene glycol-poly lactide-co-glycolic acid (PEG-PLGA) amphiphilic copolymer is an emergent system because it can be easily synthesized and possesses a lot of good qualities. Several previous in vitro and in vivo studies have evaluated the cytotoxic effects of quercetin and have revealed that it decreases cell viability and increases cell apoptotic rate in OSCC. However, the anti-cancer property of quercetin in tongue squamous cell carcinoma (TSCC) has not been studied yet. This is the first study to investigate the anticancer effects of (Quercetin) either free or encapsulated by PLGA-PEG NPs in tongue squamous cell carcinoma (TSCC) cell line.
