Focus Therapeutic Areas

Sumitomo Dainippon Pharma's goal is to create innovative pharmaceutical products. Psychiatry & Neurology as well as Oncology represent our focus therapeutic areas containing significant unmet medical needs.

In the Psychiatry & Neurology areas, Sumitomo Dainippon Pharma research and development focuses on the improvement of current treatments that do not sufficiently result in adequate symptom relief, as well as treatments to patients who are not adequately controlled by existing medical therapeutics.

In the Oncology area, under the global R&D system established by Boston Biomedical, Inc., Tolero Pharmaceuticals, Inc., and the DSP Cancer Institute, Sumitomo Dainippon Pharma aims to continually create innovative products.

In addition, Sumitomo Dainippon Pharma will apply leading-edge science, such as iPS cells to drug discovery, in order to create first-in class medicines within disease fields where no approved drugs exist and in regenerative medicine/cell therapy field.

Fundamental Technologies

Technology enhancement for improving drug discovery ability or the probability of success in the clinical development stage is indispensable for the continual creation of excellent pharmaceutical products.

Among the wide range of technical foundations and general pharmaceutical expertise possessed by Sumitomo Dainippon Pharma, in the initial stage of research, Sumitomo Dainippon Pharma is working to apply leading-edge scientific technologies, including supercomputer-assisted in silico methods and iPS cells, to drug discovery and regenerative medicine/cell therapy. Sumitomo Dainippon Pharma also proactively seeks external research collaboration with universities and other research institutions throughout the globe. During FY2016, the second term of the joint research project with Kyoto University (DSK Project), which aims to discover innovative anti-cancer drugs, was launched. Meanwhile, under the Partnership to Realize Innovative Seeds and Medicines (PRISM) framework, which is an open innovation program launched in FY2015 whereby research institutions and researchers in Japan are invited to submit ideas that meet Sumitomo Dainippon Pharma's drug discovery research needs, joint research agreements were signed on multiple ideas during FY2016.

Product Development Research

For continuously developing excellent pharmaceuticals and contributing to society, not only improvement in drug discovery ability or technology enhancement of clinical development but also enhancement of product development technology are indispensable.
We conduct research into the commercialization of promising drug candidate compounds found in drug discovery research so that they can be delivered to patients suffering from diseases as a "good medicine."

Product Development Research Process

Universal design - Orally disintegrating (OD) tablet technology

Previous OD tablets have been disadvantageous in their fragility, which often caused destruction in the middle of preparation, in spite of smooth melting in the mouth. To deal with this problem, we developed the SUITAB and PEATAB technologies for manufacturing OD tablets with excellent melting and strength and, after them, the SUITAB-NEX technology for reducing bitterness and improving stability according to drug properties.

While traditional OD tablets have been positioned as barrier-free drugs for specific cases such as infants, aged patients and those with difficulty swallowing, the new OD tablets feature a "universal" design, which is easy to take for anyone who has been taking tablets. The new technologies described above have allowed us to release the Japan-first hypertension treatment OD tablets and long-acting anti-allergic OD tablets to the market.

Nucleic acid drugs - Drug delivery system (DDS)

Nucleic acid drugs such as siRNA(*) are expected as candidates for next-generation drugs thanks to their excellent specificity and efficacy. Nevertheless, further technological innovation is required because the DDS technology for the specific introduction of the drug to the target cells is not established. At Sumitomo Dainippon Pharma, we are conducting joint research into DDS technology using atelocollagen. It is the most advanced research into practical applications for the delivery of nucleic acid drugs to the patients who need them. The atelocollagen DDS is one of the few nucleic acid DDS technologies that has been demonstrated to be effective in in vivo trials, and its high efficacy and safety have earned it a high reputation among various research institutions as well as overseas nucleic acid drug developers.

Lipiodolized drug

We developed the first platinum-based drug indicated as "adapting lipiodolization for hepatocellular carcinoma." This drug features increased suspensibility in the ethyl esters of the iodized fatty acids of poppyseed oil, thanks to the high lipophilicity of miriplatin molecules, which are its active ingredient, and its special formulation design. After having been administered in the hepatic artery, it is retained in the tumor to locally release the platinum ingredient for a long period while minimizing whole-body exposure.

Application of imaging analysis technology

To offer high-quality pharmaceuticals, we are positively tackling development and introduction of advanced analysis technologies. The imaging analysis technology that enables visual confirmation is one of such technologies. In our efforts for quality improvement, we actively use a near-infrared imaging device and X-ray CT scanner to measure and analyze the surface ingredient distribution and internal structure of a tablet without destroying it.

Drug stability prediction technology

In addition to stability prediction based on thermodynamic considerations, we are also challenging ourselves to make predictions of the future stability of drugs from the spectroscopic and physical information obtained through nonlinear analysis, represented by chemometrics, etc. For instance, with the aim of improving product quality, we are studying a stability prediction method using a near-infrared (NIR) analyzer.
