R&D strategy

Raphas’ DEN manufacturing technology has been quickly recognized in the derma cosmetics market, and its competitiveness has been increased by verifying its convenience and stability. Raphas is conducting further research with its partners in order to apply it to medical devices, specialized drugs, and vaccines.

Rapid commercialization strategy
for improved new drugs applying microneedle

Bioequivalence can be verified by changing the formulation of an existing drug.
Based on the verification, a manufacturer can omit phases 2 and 3 of the clinical trials and mass produce a drug for rapid commercialization.

  1. High performance and high consumer convenience
    compared to existing licensed formations .
  2. Relatively low
    development cost
  3. Rapid commercialization
    with a high clinical trial
    success rate
Rapid commercialization with proven bioequivalence

R&D outcome

Raphas has completed 42 human application tests such as clinical efficacy tests and skin irritation tests to prove the safety and efficacy of all its products.
Raphas has signed a partnership with a global vaccine manufacturer based on its DEN manufacturing technology, and is conducting joint R&D of candidate strains with the aim of developing new vaccines.

Medical device :
Drug absorption inducer

  • Brand : Therapass
  • Development background
    Coating drugs that re widely used in the treatment of skin diseases tend to have the disadvantage of having to administer too much of the drug or take it for too long as human skin's absorbance of the drug is low. To solve this problem, Raphas has developed a medical device designed to promote the absorption of coating drugs.
  • Partnership
    MIAT and Samoh Pharmaceutical
  • Development output
    1. Class 3 medical device licensed by the MFDS
    2. Completion of clinical study on drug absorption inducement for psoriasis patients
    3. Completion of clinical study on drug absorption inducement for prurigo nodularis patients
