Drug Safety Evaluation Services
Protheragen provides specialized preclinical drug safety evaluation services for rare neurodegenerative disorders. Our team combines advanced technologies with scientific expertise to deliver reliable data, supporting the development of safer and more effective therapies.
The Role of Drug Safety Evaluation in Rare Neurodegenerative Diseases
Rare neurodegenerative diseases, such as ALS, Huntington's disease, and spinal muscular atrophy, involve progressive neuronal degeneration and severe functional decline. Their low prevalence and biological complexity pose significant challenges for therapeutic development. Rigorous drug safety evaluation is essential to ensure candidate therapies are both safe and effective before advancing to clinical trials.
Key Considerations
- The Necessity of Safety Evaluation
Safety assessment is a mandatory step before clinical testing and regulatory approval. For rare diseases, this process is particularly critical due to small patient populations and complex trial designs. Traditional methods often lack the speed and precision required, driving demand for innovative approaches to identify toxicity risks and establish safety profiles efficiently. - Applications of Safety Evaluation
- Toxicity Threshold Identification: Determine acute and chronic toxicity doses to establish safe exposure limits.
- Safe Dose Range Definition: Identify dosage levels that balance efficacy with minimal adverse effects.
- Target Organ Toxicity Analysis: Pinpoint organs or tissues affected by drug toxicity to guide monitoring and structural drug optimization.
- Toxicity Reversibility Assessment: Evaluate whether drug-induced damage is reversible and estimate recovery timelines.

We employ in vitro assays, animal models, and advanced analytics to address these priorities, ensuring robust safety data that aligns with regulatory standards. Our workflows are designed to identify risks early, reduce late-stage failures, and accelerate the translation of promising therapies into clinical testing.
Our Services
At Protheragen, our drug safety evaluation services are structured to facilitate preclinical development for therapies targeting rare neurodegenerative diseases. We prioritize rigorous assessment of treatment safety and efficacy prior to clinical trial progression, delivering actionable data to support development decisions.
Core Services
General Toxicity Studies
Our toxicity assessments evaluate systemic drug effects across organ systems using standardized animal models (rodent and non-rodent). Key phases include:
- Acute Toxicity: Single-dose exposure analysis with clinical symptom monitoring
- Subchronic/Chronic Toxicity: Multi-dose regimens (≥90 days) with histopathological and physiological evaluations
- Carcinogenicity: Long-term tumorigenicity risk profiling
Genetic Toxicity Studies
We assess mutagenic and clastogenic risks through validated methodologies:
- In Vitro Models: Bacterial and mammalian cell systems for gene mutation and chromosomal damage detection
- In Vivo Models: Rodent-based micronucleus assays to evaluate genomic instability
Safety Pharmacology Studies
Functional impact on vital systems is analyzed via:
- Cardiovascular: Continuous telemetric monitoring of hemodynamic parameters (heart rate, blood pressure, ECG)
- Respiratory: Plethysmography-based quantification of pulmonary function
- Central Nervous System: Behavioral observation and neurotoxicity screening
