Amikacin

What is Amikacin?

CAS No: 37517-28-5

Amikacin is a semi-synthetic aminoglycoside antibiotic that is derived from kanamycin A. Amikacin is synthesized by acylation with the l-(-)-γ-amino-α-hydroxybutyryl side chain at the C-1 amino group of the deoxystreptamine moiety of kanamycin A. Amikacin’s unique property is that it exerts activity against more resistant gram-negative bacilli such as Acinetobacter baumanii and Pseudomonas aeruginosa. Amikacin also exerts excellent activity against most aerobic gram-negative bacilli from the Enterobacteriaceae family, including Nocardia and some Mycobacterium (M. avium-intracellulare, M. chelonae, and M. fortuitum). M. avium-intracellulare (MAC) is a type of nontuberculous mycobacteria (NTM) found in water and soil. Symptoms of this disease include a persistent cough, fatigue, weight loss, night sweats, and shortness of breath and the coughing up of blood. Several forms of amikacin are used currently, including an intravenous (IV) or intramuscular (IM) injection. In September 2018, a liposomal inhalation suspension of this drug was approved by the FDA for the treatment of lung disease caused by Mycobacterium avium complex (MAC) bacteria in a small population of patients with the disease who do not respond to traditional treatment.

To derive PDE/ADE, OEL, and OEB values, Masuu Global follows a scientifically justified, risk-based toxicological assessment approach in accordance with internationally recognized guidelines and industry best practices that are widely accepted by regulatory authorities, including European Medicines Agency (EMA), Pharmaceutical Inspection Co-operation Scheme (PIC/S), and Agência Nacional de Vigilância Sanitária (ANVISA).

Assessment Methodology

Masuu Global follows a scientifically justified, risk-based toxicological approach aligned with internationally recognized guidelines accepted by EMA, PIC/S, and ANVISA.

EMA – Guideline on Setting Health-Based Exposure Limits (HBELs)

Provides the framework for establishing scientifically justified PDE/ADE values for use in shared manufacturing facilities.

PIC/S – Shared Facilities and Contamination Control Guidance

Supports the application of HBEL-based approaches for cross-contamination prevention and cleaning validation.

ICH Q9 – Quality Risk Management

Provides a structured methodology for risk identification, assessment, control, communication, and review.

ICH M7 – Assessment and Control of DNA-Reactive (Mutagenic) Impurities (where applicable)

Applied for compounds with potential mutagenic or genotoxic concerns.

Risk-Based Toxicological Assessment

Comprehensive evaluation of available toxicological and pharmacological data, including NOAEL, LOAEL, BMDL, pharmacological potency, carcinogenicity, reproductive and developmental toxicity, sensitization potential, and target organ toxicity.

Weight-of-Evidence (WoE) Approach

Integration and critical review of all relevant data sources, including non-clinical studies, clinical studies, human exposure data, pharmacological information, post-marketing safety data, and structure–activity relationship (SAR/QSAR) assessments.

Report Preparation Process

Every assessment moves through a rigorous five-stage workflow — from data gathering to regulatory-ready delivery.

01

Comprehensive Data Review

Assessment of pharmacology, toxicology, clinical data, literature, and available regulatory information.

02

Scientific Evaluation

Identification of critical endpoints and selection of appropriate exposure limits.

03

PDE / HBEL Derivation

Transparent and scientifically justified calculations aligned with global toxicological principles.

04

Ex-Agency Expert Review (Our Differentiator)

Reports are reviewed with an ex-agency perspective, bringing regulatory expectations, inspection readiness, and practical implementation into every assessment.

05

Final Report Delivery

Regulatory-ready reports with scientific rationale, calculations, and clear recommendations by certified toxicologists (ERT, UKRT and DABT).
