Clinical Development ─ Investigating effectiveness and safety

The final process of new drug development that also considers patient quality of life (QOL)

Clinical trials (drug trials) investigate the effectiveness and safety of new drug on humans to obtain approval for its manufacture and sale. This is the final and most important stage in the new drug development process. It is self-evident that clinical trials are subject to the highest ethical and scientific standards. In this context, it is also important to test the possibilities of mitigating patient load in terms of drug administration frequency and other factors. Kyorin is actively engaged in clinical trials both in Japan and abroad. Moreover, we seek to conduct effective development through joint projects with other companies and the use of contract research organizations (CROs).

  • CRO:Contract Research Organization
Clinical trials start with the exchange of opinions and coordination.

In clinical development work, it is important for other departments within a company and those with various external viewpoints such as doctors and clinical research coordinators (CRCs) to work together. Through repeated exchanges of opinions and coordination, the parties involved develop a plan for the clinical trials, select an institution and commence the clinical trials. To ensure that new drugs are introduced into medical practice as soon as possible, we focus on collecting accurate data and seek to speed up the process.

Trial Phase
Phase Major Trials Details
Phase I Clinical Pharmacology Trial
  • Trials on healthy individuals
  • Mainly looking at safety and pharmacokinetics
Phase II Exploratory Trial
  • Trials on patients (small number)
  • Looking at effectiveness and safety
  • Determination of dosage
Phase III Verification Trial
  • Trials on patients (greater sample size)
  • Confirmation of effectiveness and safety in actual clinical use through comparison trials and general trials
  • Usage and dosage for applicable diseases
Phase IV Therapeutic Trial
  • Post-marketing clinical trials
  • Surveys of actual usage
  • Special surveys

Drug Fostering Research ─ Developing easier-to-use drugs

Drug fostering research involves finding more effective methods of use and new pharmacological effects, and providing useful information on pharmaceuticals to medical practice.

Pharmaceuticals are released after clinical trials involving patients of limited ages, complications and other attributes. However, in actual medical practice, those pharmaceuticals are used on patients with various backgrounds. Drug fostering research is the process of finding more effective and safer uses or new pharmacological effects for post-marketing pharmaceuticals, and enhancing their added value. By incorporating the information gained from drug fostering research, drugs which are easier to use can be developed. We contract with universities, research institutes and medical institutions to conduct basic tests and clinical trials to build up a scientific basis. The results are made public through scientific presentations or article contributions, and the information provided to those involved with medical treatment such as doctors and pharmacists.

Drug fostering is equally important as new drug development to pharmaceutical companies

To pharmaceutical companies, the fostering of existing drugs is just as important as the development of new ones. For the purpose of drug fostering, KYORIN Pharmaceutical has established the Drug Fostering Promotion Dept. as a dedicated section. The department investigates the possibilities for existing drugs such as Mucodyne and Uritos.

Some of the results yielded by drug fostering research
Viral infection inhibitory effects of carbocisteine (Mucodyne)
Fundamental clarification that carbocisteine inhibits influenza virus and rhinovirus infection in human skin cells.
Effect of carbocisteine in inhibiting acute exacerbation of chronic obstructive pulmonary disease (COPD) (PEACE Study)
In a placebo-controlled double-blind comparison study conducted in China, carbocisteine was shown to inhibit acute exacerbation in COPD patients. The results of the study were published in the world renowned medical journal LANCET.
Beneficial effects of imidafenacin (Uritos) on nocturia
Imidafenacin was shown to improve the quality of sleep and daytime drowsiness by improving nocturia.
Epidemiological study on stroke patient QOL (OASIS Study)
Dizziness reducing the QOL of stroke patients, and ibudilast (Ketas) was shown to improve QOL by improving dizziness. A paper about this research won an award from the Society of Neurological Therapeutics.
