Insights

Metastatic bladder cancer is a deadly disease. Repurposed drugs ramelteon, fluoxetine, dapsone, and celecoxib (UBC4 regimen) show promise in preclinical studies as an adjunct cancer treatment.

Area of Science:

  • Oncology
  • Pharmacology
  • Urology

Background:

  • Metastatic bladder cancer remains a significant cause of mortality despite extensive treatments.
  • The drug repurposing movement seeks existing medications for novel oncological applications.

Purpose of the Study:

  • To identify existing medications that can inhibit key growth drivers in metastatic bladder cancer.
  • To present preclinical data supporting the UBC4 regimen (ramelteon, fluoxetine, dapsone, celecoxib) as a potential adjunct therapy.

Main Methods:

  • Review of preclinical data on four general medical drugs: ramelteon, fluoxetine, dapsone, and celecoxib.
  • Evaluation of their potential to inhibit identified growth elements in bladder cancer.

Main Results:

  • Extensive preclinical evidence demonstrates growth inhibition of bladder cancer by each of the UBC4 drugs individually.
  • The UBC4 regimen drugs are generally well-tolerated with a low risk profile.

Conclusions:

  • The UBC4 regimen shows potential as an adjunct therapy for metastatic bladder cancer.
  • Strong preclinical data justifies a clinical pilot trial for the UBC4 regimen in patients with advanced bladder cancer.

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
Treatment Resistent Cancers02:56

Treatment Resistent Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
