반응형

Atopic Dermatitis Th2 response 분야 쪽으로 타겟해야되어 있고 topical 제제 PDE4 JAK1 inhibitor쪽이 있고

바이오의약품쪽은 많지는 않은 상황. TNFa 딱히 효과 없는것 같고 IL-4/IL-13 주류. JAK inhibitor 있는데 JAK 부작용 때문에 비주류로 우선 분류.

 

IL-4/IL-13

  • Dupilumab (IL-4Ra)
  • Lebrikizumab (IL-13)
  • Tralokinumab (IL-13)

TSLP-OX40

  • Tezepelumab (TSLP)
  • Rocantilimab (OX40)
  • Amlitilimab (OX40L)

(출처: GlobalData)

 

주요 품목들 예상 매출. Dupilumab Asthma쪽도 크고 해서 매출이 엄청나게 나오는 것으로 알고 있음.

Lebrikizumab pure AD 플레이어라고 보면 될듯.

개발중인 파이프라인 Amtelimab Rocatinlimab 있는데 두가지 다른 점은 Roca OX40 타겟 vs Amli OX40L

 

Dupilumab Common AE로는 Conjunctivitis (5-28% 발생)

IL-4인지 IL-13 원인인지는 모르겟으나, OX40쪽도 그렇고 conjunctivitis 많이 발생하는 같음.

 

 

단독 그리고 스테로이드 병용 허가용 임상에서 결과 수치 정리

 

개발중인 Amlitelimab Rocatinlimab 결과.

최근 Rocatinlimab ROCKET-Horizon 임상에서 primary endpoint met 정도로만 발표함. 세부 내역은 추후 학회 공개 예정인데, 시장에서 기대감이 낮은듯.
