Abstract

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a transglutaminase (TGM) polypeptide (e.g., a Transglutaminase-1 (TGM1) polypeptide); viruses comprising the recombinant nucleic acids; compositions comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

Claims (36)

1. A pharmaceutical composition comprising:

(a) a herpes virus comprising a recombinant herpes virus genome, wherein the recombinant herpes virus genome comprises one or more polynucleotides encoding a transglutaminase 1 (TGM1) polypeptide; and

(b) a pharmaceutically acceptable excipient.

2. The pharmaceutical composition of claim 1 , wherein the recombinant herpes virus genome is replication competent.

3. The pharmaceutical composition of claim 1 , wherein the recombinant herpes virus genome is replication defective.

4. The pharmaceutical composition of claim 1 , wherein the recombinant herpes virus genome is selected from the group consisting of a recombinant herpes simplex virus genome, a recombinant varicella zoster virus genome, a recombinant human cytomegalovirus genome, a recombinant herpesvirus 6A genome, a recombinant herpesvirus 6B genome, a recombinant herpesvirus 7 genome, a recombinant Kaposi's sarcoma-associated herpesvirus genome, and any derivatives thereof.

5. The pharmaceutical composition of claim 1 , wherein the recombinant herpes virus genome is a recombinant herpes simplex virus type 1 (HSV-1) genome.

6. The pharmaceutical composition of claim 5 , wherein the recombinant HSV-1 genome comprises an inactivating mutation in a herpes simplex virus gene selected from the group consisting of Infected Cell Protein (ICP) 0, ICP4, ICP22, ICP27, ICP47, thymidine kinase (tk), Long Unique Region (UL) 41, and UL55.

7. The pharmaceutical composition of claim 1 , wherein the TGM1 polypeptide is a human TGM1 polypeptide.

8. The pharmaceutical composition of claim 1 , wherein the TGM1 polypeptide has at least 80% sequence identity to the amino acid sequence of SEQ ID NO: 5.

9. The pharmaceutical composition of claim 1 , wherein the herpes virus has reduced cytotoxicity as compared to a corresponding wild-type herpes virus.

10. The pharmaceutical composition of claim 1 , wherein the herpes virus is selected from the group consisting of a herpes simplex virus, a varicella zoster virus, a human cytomegalovirus, a herpesvirus 6A, a herpesvirus 6B, a herpesvirus 7, and a Kaposi's sarcoma-associated herpesvirus.

11. The pharmaceutical composition of claim 1 , wherein the herpes virus is a herpes simplex virus type 1 (HSV-1).

12. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is suitable for topical, transdermal, or intradermal administration.

13. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is suitable for topical administration.

14. A method of providing prophylactic, palliative, or therapeutic relief to one or more signs or symptoms of TGM1-deficient autosomal recessive congenital ichthyosis (ARCI) in a subject in need thereof, the method comprising administering to the subject an effective amount of a pharmaceutical composition comprising:

(a) a herpes virus comprising a recombinant herpes virus genome, wherein the recombinant herpes virus genome comprises one or more polynucleotides encoding a transglutaminase 1 (TGM1) polypeptide; and

(b) a pharmaceutically acceptable excipient;

wherein the pharmaceutical composition is administered topically, transdermally, or intradermally to the subject; and

wherein administration of the pharmaceutical composition affects a measurable improvement or prevention of the one or more signs or symptoms of TGM1-deficient ARCI.

15. The method of claim 14 , wherein the subject is a human.

16. The method of claim 14 , wherein the one or more signs or symptoms of TGM1-deficient ARCI are selected from the group consisting of an abnormal stratum corneum, incomplete thickening of the cornified cell envelope, defects in the intercellular lipid layers in the stratum corneum, generalized scaling with variable redness of the skin, formation of large plate-like scales, accelerated epidermal turnover, palmoplantar hyperkeratosis, defective barrier function, recurrent skin infections, exposure keratitis, hypohidrosis, heat intolerance, corneal perforation, rickets, nail abnormalities, dehydration, respiratory problems, ectropion, eclabium, hypoplasia of joint and nasal cartilage, hypotrichosis, scarring alopecia, renal insufficiency, sepsis, and any combinations thereof.

17. The method of claim 14 , wherein the subject suffers from lamellar ichthyosis (LI).

18. The method of claim 14 , wherein the pharmaceutical composition is administered topically to the subject.

19. The method of claim 18 , wherein the skin of the subject is abraded prior to administration.

20. The method of claim 14 , wherein the recombinant herpes virus genome is selected from the group consisting of a recombinant herpes simplex virus genome, a recombinant varicella zoster virus genome, a recombinant human cytomegalovirus genome, a recombinant herpesvirus 6A genome, a recombinant herpesvirus 6B genome, a recombinant herpesvirus 7 genome, a recombinant Kaposi's sarcoma-associated herpesvirus genome, and any derivatives thereof.

21. The method of claim 14 , wherein the recombinant herpes virus genome is a recombinant herpes simplex virus type 1 (HSV-1) genome.

22. The method of claim 21 , wherein the recombinant HSV-1 genome comprises an inactivating mutation in a herpes simplex virus gene selected from the group consisting of Infected Cell Protein (ICP) 0, ICP4, ICP22, ICP27, ICP47, thymidine kinase (tk), Long Unique Region (UL) 41, and UL55.

23. The method of claim 14 , wherein the TGM1 polypeptide is a human TGM1 polypeptide.

24. The method of claim 14 , wherein the TGM1 polypeptide has at least 80% sequence identity to the amino acid sequence of SEQ ID NO: 5.

25. The method of claim 14 , wherein the herpes virus has reduced cytotoxicity as compared to a corresponding wild-type herpes virus.

26. The method of claim 14 , wherein the herpes virus is selected from the group consisting of a herpes simplex virus, a varicella zoster virus, a human cytomegalovirus, a herpesvirus 6A, a herpesvirus 6B, a herpesvirus 7, and a Kaposi's sarcoma-associated herpesvirus.

27. The method of claim 14 , wherein the herpes virus is a herpes simplex virus type 1 (HSV-1).

28. The method of claim 14 , wherein the recombinant herpes virus genome is replication competent.

29. The method of claim 14 , wherein the recombinant herpes virus genome is replication defective.

30. The method of claim 14 , wherein the one or more signs or symptoms of TGM1-deficient ARCI is defective barrier function.
