Abstract

The present invention relates to methods and compositions for the prevention and treatment of keratin-based skin diseases. In particular, the application describes compositions and methods of treating a patient suffering from skin blistering comprising the use of phase II enzyme inducers.

Claims (47)

1. A method for treating or preventing skin blistering in a patient in need thereof or at risk of developing skin blistering, comprising administering to the patient a composition comprising a therapeutically effective amount of an Nrf2 inducer.

2. The method of claim 1 , wherein the patient suffers from skin blistering.

3. The method of claim 1 , wherein the Nrf2 inducer is a phase II enzyme inducer.

4. The method of claim 3 , wherein the phase II inducer is an isothiocyanate.

5. The method of claim 4 , wherein the phase II enzyme inducer is sulforaphane.

6. The method of claim 4 , wherein the phase II enzyme inducer is a sulforaphane synthetic analogue.

7. The method of claim 6 , wherein the sulforaphane synthetic analogue is exo-2-acetyl-6-isothiocyanatonorbomane.

8. The method of claim 1 , wherein the Nrf2 inducer is keratinocyte growth factor.

9. The method of claim 1 , wherein the Nrf2 inducer is oltipraz.

10. The method of claim 1 , wherein the Nrf2 inducer is ethacrynic acid.

11. The method of claim 1 , wherein the Nrf2 inducer causes the selective induction of K6, K16 or K17 in the keratinocytes in the skin of the patient.

12. The method of claim 1 , wherein the composition comprising the NRF2 inducer is topically administered to the patient.

13. The method of claim 12 , wherein the amount of Nrf2 inducer in the composition topically administered to the patient is from about 100 nmol/cm2 to about 1 μmol/cm2.

14. The method of claim 12 , wherein the composition comprising the Nrf2 inducer is a topical preparation selected from the group consisting of ointment, cream, emulsion, lotion and gel.

15. The method of claim 13 , wherein the composition father comprises one or more pharmaceutical, biological or molecular biological active agents.

16. The method of claim 1 , wherein the patient is a mammal.

17. The method of claim 16 , wherein the mammal is a human.

18. The method of claim 1 , wherein the patient suffers from Epidermolysis bullosa simplex.

19. The method of claim 1 , wherein the patient suffers from Epidermolysis bullosa simplex-Weber-Cockayne type, Epidermolysis bullosa simplex-Koebner type, Epidermolysis bullosa simplex with mottled pigmentation, Epidermolysis bullosa simplex-Dowling-Meara type, or Epidermolysis bullosa simplex with muscular dystrophy.

20. The method of claim 19 , wherein the Epidermolysis bullosa simplex is caused by a mutation at the K14 locus.

21. The method of claim 1 , wherein the Nrf2 inducer is a phase II enzyme inducer.

22. The method of claim 21 , wherein the phase II inducer is an isothiocyanate.

23. The method of claim 21 , wherein the phase II enzyme inducer is sulforaphane.

24. The method of claim 21 , wherein the phase II enzyme inducer is a sulforaphane synthetic analogue.

25. The method of claim 24 , wherein the sulforaphane synthetic analogue is exo-2-acetyl-6-isothiocyanatonorbornane.

26. The method of claim 1 , wherein said skin blistering is a keratin-based skin disease.

27. The method of claim 26 , wherein the keratin-based skin disease is selected from the group consisting of epidermolytic hyperkeratosis, ichtyosis bullosa of Siemens, pachyonychia congenita, epidermolytic or non-epidermolytic palmoplantar keratoderma (diffuse or focal) steatocystoma multiplex, Naegeli-Franceschetti4adessohn syndrome and dermatopathia pigmentosa reticularis.

28. The method of claim 26 , wherein the disease is caused by a mutation at the K14 locus.

29. The method of claim 26 , wherein the Nrf2 inducer is a phase II enzyme inducer.

30. The method of claim 29 , wherein the phase II inducer is an isothiocyanate.

31. The method of claim 29 , wherein the phase II enzyme inducer is sulforaphane.

32. The method of claim 29 , wherein the phase II enzyme inducer is a sulforaphane synthetic analogue.

33. The method of claim 32 , wherein the sulforaphane synthetic analogue is exo-2-acetyl-6-isothiocyanatonorbornane.

34. The method of claim 26 , wherein the Nrf2 inducer is keratinocyte growth factor.

35. The method of claim 26 , wherein the Nrf2 inducer is oltipraz.

36. The method of claim 26 , wherein the Nrf2 inducer is ethacrynic acid.

37. The method of claim 26 , wherein the Nrf2 inducer causes the selective induction of K6, K16 or K17 in the keratinocytes in the skin of the patient.

38. The method of claim 26 , wherein the composition comprising the Nrf2 inducer is topically administered to the patient.

39. The method of claim 38 , wherein the amount of Nrf2 inducer in the composition topically administered to the patient is from about 100 nmol to about 1 μmol/cm2.

40. The method of claim 38 , wherein the composition comprising the Nrf2 inducer is a topical preparation selected from the group consisting of ointment, cream, emulsion, lotion and gel.

41. The method of claim 39 , wherein the composition further comprises one or more pharmaceutical, biological or molecular biological active agents.

42. The method of claim 26 , wherein the patient is a mammal.

43. The method of claim 42 , wherein the mammal is a human.

44. The method of claim 15 , wherein the one or more pharmaceutical, biological or molecular biological active agents comprises jojoba oil.

45. The method of claim 41 , wherein the one or more pharmaceutical, biological or molecular biological active agents comprises jojoba oil.

46. The method of claim 1 , further comprising identifying a patient with skin blistering or pre-disposed to developing skin blistering.

47. The method of claim 1 , wherein the method comprises treating skin blistering in a patient in need thereof comprising administering to the patient a composition comprising a therapeutically effective amount of an Nrf2 inducer.
