Preclinical Development: Overview01:28

Preclinical Development: Overview

5.7K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Clinical Trials: Overview01:11

Clinical Trials: Overview

4.5K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Drug Discovery: Overview01:26

Drug Discovery: Overview

10.9K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Drug Administration and Therapy Phases: Overview

1.1K
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

In Vitro Drug Release Testing: Overview, Development and Validation

279
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Drug Regulation01:25

Drug Regulation

2.7K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Area of Science:

  • Neuroscience
  • Neurology
  • Pharmacology

Background:

  • Dementia with Lewy bodies (DLB) is a common dementia characterized by alpha-synuclein aggregates, causing cognitive, psychiatric, and sleep disturbances.
  • DLB presents significant care costs, and lacks FDA-approved treatments, prompting increased interest from drug developers.
  • Patient-Focused Drug Development (PFDD) meetings aim to integrate patient experiences into drug development.

Purpose of the Study:

  • To capture the lived experiences, treatment needs, and preferences of individuals with DLB and their care partners.
  • To inform drug developers and regulatory agencies about patient priorities for future DLB therapies.
  • To guide the development of effective and patient-centered treatments for DLB.

Main Methods:

  • An externally-led PFDD (EL-PFDD) meeting on DLB was co-hosted by the Lewy Body Dementia Association (LBDA) and Alzheimer's Association (ALZ).
  • Public comments were solicited on lived experiences and treatment values prior to the meeting.
  • Attendees, including people with DLB, care partners, and industry/regulatory representatives, shared experiences and participated in live polling.

Main Results:

  • The most impactful symptoms included cognitive impairment, fluctuations, neuropsychiatric features, and sleepiness, varying with disease progression.
  • Future concerns centered on progressive cognitive decline, behavioral changes, and care costs.
  • Current treatment limitations involve a lack of FDA-approved options and side effects/inefficacy of off-label medications.

Conclusions:

  • The EL-PFDD meeting successfully gathered crucial patient insights for DLB drug development and regulatory considerations.
  • Priorities for future treatments include symptomatic relief, disease-modifying therapies, improved accessibility, and minimized side effects.
  • A comprehensive 'Voice of the Patient' report will be published on the LBDA website.
