Method Development
1. Related substances are impurities in drugs except the main components. They may be raw materials, intermediates, reagents, decomposition products, by-products, polymers and isomers brought in during the synthesis of APIs, and degradation products produced during storage, transportation and use. As the content of related substances is generally small, it is very important to choose a detection method featuring good specificity, high sensitivity and great reproducibility.
2. For drugs beyond standards, the methods of related substances shall be developed according to drug properties, product characteristics, FDA, pharmacopoeias of various countries, relevant materials, and optimized to meet the requirements of ICH and pharmacopoeias of various countries for related substances.
3. For drugs within national standards, it is not acceptable to refer to existing national standards mechanically. The principle shall be “follow the category not the standard”, i.e., in the research of drugs within existing national standards, the safety and effectiveness of the developing products should be consistent with those of the products available on the market, and specific standards shall be set for specific categories.

Stability Study:
Verification of analytical methods provides scientific basis for the determination of production, packaging, storage, transportation conditions and validity period of pharmaceutical products by investigating the laws of the changes of the properties of APIs and preparations with time under the influence of temperature, humidity and light, so as to ensure the safety and effectiveness of clinical medication. Stability study is one of the main contents of drug quality control research. It is closely related to drug quality research and the establishment of quality standards.

Laboratory-scale Preparation and Pilot-scale Preparation
Equipped with Tofflon's freeze dryers, Thermo Fisher Scientific's hot melt extruder and Yamato's spray dryers, Rochi Pharma is capable of laboratory-scale test for oral administration, injection, external use and various preparations.
Based on the concept of Quality by Design (QbD), the laboratory-scale test aims to conduct design of experiment (DOE) and research targeting at medium/high risks, after the early determination of quality target product profile (QTPP) and critical quality attributes (CQA) and preliminary risk assessment based on CQA. With understanding and control strategy based on the critical material attributes (CMA) and critical process parameters (CPP), the formulation process can be determined and the risks can be lowered.
If the samples for laboratory-scale tests are approved for batch tests, facilities for pilot-scale tests, such as rotary tablet presses and hopper mixers, are recommended to avoid scale-up failure caused by facilities featuring different principles (such as the difference of dwell time between the single punch tablet press and the rotary tablet press).
We verify our understanding of formulation process by preparing samples for laboratory-scale tests to determine whether the CQA of products of such formulation process can be guaranteed.
During laboratory-scale tests, we not only focus on the quality of finished products, but also establish draft quality standards for intermediates. We also pay attention to the mixing uniformity, particle fluidity, and the possibility of delamination during tableting or filling.
In the meantime, for 1~3 months, we will conduct influencing factor & acceleration tests based on samples for laboratory-scale tests to explore the stability of such samples, so as to provide reference for the improvement of formulation process, the development of quality standard draft and the stability of subsequent pilot-scale test samples.

Pilot-scale Preparation Testing:
For oral solid preparations, we can conduct laboratory-scale production and preliminary stability study. After the determination of the formulation process, the preliminary stability of samples and the proposed inner packaging materials, we will prepare relevant documents and materials for pilot-scale tests.
Preparation of documents for pilot-scale tests
1.Scheme of pilot-scale tests
2.Records for batch production & packaging
3.Draft quality standard for finished products
4.Draft quality standard for intermediates
Preparation-making for pilot-scale tests:
1.Collection of APIs
2.Procurement of ingredients and packaging materials
3.Determination or customization of tableting, capsule filling and aluminum-plastic molds
The preparation of documents and materials shall be made during the pre-stability period of laboratory-scale test to meet the requirements of the new drug project for the schedule and time limit.
The sample production for pilot-scale test includes:

1.Pretreatment of raw materials (mechanical crushing, airflow crushing, etc.)
2.Mixing - box-type mixing or high shear mixing
3.Granulating - wet granulating, dry granulating and fluidized bed granulating
4.Drying - fluidized bed drying and oven drying
5.Sieving -fast sieving equipment
6.Tableting - high-speed tablet press
7.Capsule filling - capsule filling machine, available for granules, powders or pellets at the same time
8.Coating - efficient coating machine with digital display of key parameters
9.Packaging - aluminum-plastic packaging and bottle packaging
The documents for pilot-scale test shall be released after being drafted and taken into effect, and implemented under a sound management system.
As a transition between laboratory-scale batches and clinical batches, pilot-scale batches shall be produced based on the risk control strategy in process research and the production experience of multiple drug varieties. As the equipment basically corresponds to GMP-based workshop, seamless connection with later GMP-based batches and the successful production of clinical samples can be both guaranteed.
Samples for pilot-scale tests are mainly used for the verification of analytical methods and the research on stability.
GMP-based Clinical Sample Production & Packaging:
