4. Detailed Implementation and Results
Formulation Development:
4. Enhanced Formulation Development
Development of ODT Prototypes:
- Prototype
Variants: Developed over 30 distinct prototypes with variations
in API concentration to cater to different pediatric age groups and
dosages.
- Flavor
Development: Employed advanced flavor masking techniques, using
encapsulation and complexation methods to mask the API’s bitterness
effectively. Specific flavors were chosen based on preference studies
conducted in pediatric populations, including fruity flavors like
strawberry, orange, and grape.
- Texture
and Mouthfeel: Focused on optimizing the mouthfeel to be pleasant
for children. Techniques included microencapsulation to enhance smoothness
and reduce grittiness, ensuring the tablets dissolve quickly and leave no
unpleasant residues.
Advanced Stability Testing:
- Accelerated
and Real-Time Stability Testing: Conducted comprehensive
stability studies, including accelerated (40°C/75% RH) and real-time
conditions, tracking the stability of ODTs over a 24-month period.
- API
Stability: Used high-performance liquid chromatography (HPLC) to
monitor the stability of the API in the ODT formulation, ensuring that
degradation products remained within acceptable limits.
- Moisture
Sensitivity: Employed novel packaging techniques with desiccants
to combat moisture sensitivity, a critical factor in ODT stability.
Disintegration and Release Studies:
- Rapid
Disintegration Testing: Ensured that the ODTs disintegrated
within 30 seconds in simulated saliva conditions, which is crucial for
pediatric compliance.
- In
Vitro Release Profile: Conducted dissolution studies to ensure a
consistent release profile of the API, mimicking the in vivo conditions.
Targeted a release of 80% of the API within the first 3 minutes to ensure
rapid onset of action.
Batch Consistency and Scale-Up:
- Pilot
Scale Batches: Initially, pilot-scale batches of 1000 tablets
were produced to test the scalability of the formulation. Key parameters
like weight variation, hardness, and friability were closely monitored.
- Scale-Up
to Clinical Trial Batches: Scaled up the manufacturing process to
produce batches of 5,000 to 15,000 tablets while maintaining stringent
control over quality parameters. Utilized a high-speed rotary press for
large-scale production, ensuring consistency across batches.
Regulatory Strategy:
- Preparing
detailed documentation for FDA submission, including preclinical safety
data, proposed clinical trial protocols, and manufacturing process
details.
- Engaging
with FDA representatives through pre-IND meetings to ensure alignment with
regulatory expectations.
Clinical Trial Manufacturing:
- Establishing
robust protocols for batch production, ensuring consistency and
traceability.
- Developing
child-friendly packaging that incorporates safety features and ease of
use.
- Batch
Sizes: Producing 5,000 to 15,000 tablet batches for clinical
trials.
- Packaging
Innovations: Achieving an 18% reduction in packaging costs.
Results:
- Feedback
from Initial Testing: Positive responses from pediatricians and
caregivers about the ease of administration and acceptance by children.
- Regulatory
Advancements: Received FDA’s Pediatric Study Plan (PSP)
agreement, a crucial milestone in pediatric drug development.
- Preparation
for Global Markets: Initiated discussions for regulatory
submissions in the European Union and other international markets,
anticipating global demand.
- Patient
Adherence: Improved from 50% to 85% in trials.
- Regulatory
Success: IND approved within 10 months with minimal queries.
- Cost
Reduction: 25% reduction in per-unit manufacturing cost.
