TREATMENT OF NEUROPATHY WITH DNA CONSTRUCT EXPRESSING HGF ISOFORMS WITH REDUCED INTERFERENCE FROM GABAPENTINOIDS
The present invention relates to methods of treating neuropathy patients who have been administered a gabapentinoid. In particular, the methods involve administering a nucleic acid construct encoding human HGF proteins after discontinuing gabapentinoid. The present invention provides a novel method for a specific patient population to achieve a better therapeutic outcome by avoiding interference of therapeutic effects by gabapentinoids.
1 . A method of treating neuropathy, comprising the steps of:
selecting a patient with neuropathy who has been administered a gabapentinoid,
discontinuing gabapentinoid administration to the patient, and
administering VM202 to the patient.
2 . The method of claim 1 , further comprising the step of:
withholding gabapentinoid administration for at least a week after the step of administering VM202.
3 . The method of claim 1 , further comprising the step of:
withholding gabapentinoid administration for at least 10 days after the step of administering VM202.
4 . The method of any of claims 1 - 3 , wherein the step of discontinuing gabapentinoid administration comprises tapering gabapentinoid administration.
5 . The method of any of claims 1 - 4 , wherein the step of administering VM202 is performed after a complete cessation of gabapentinoid administration.
6 . The method of claim 5 , wherein the step of administering VM202 is performed at least 1, 2, 3, 5, 7, 14, 21, 30, 60, or 90 days after a complete cessation of gabapentinoid administration.
7 . The method of any of claims 1 - 6 , wherein the neuropathy is diabetic peripheral neuropathy.
8 . The method of any of claims 1 - 6 , wherein the neuropathy is post-herpetic neuropathy.
9 . The method of any of claims 1 - 8 , wherein the gabapentinoid is gabapentin or pregabalin.
10 . The method of any of claims 1 - 9 , wherein the step of administering VM202 comprises administering 8 mg of VM202 per affected limb of the patient, equally divided into a plurality of intramuscular injections and plurality of visits, wherein each of the plurality of intramuscular injections in any single visit is performed at a separate injection site.
11 . The method of claim 10 , wherein VM202 is administered at a dose of 16 mg equally divided into 64 intramuscular injections,
wherein 16 intramuscular injections are administered to separate injection sites on a first calf on a first visit,
wherein 16 intramuscular injections are administered to separate injection sites on a second calf on the first visit,
wherein 16 intramuscular injections are administered to separate injection sites on the first calf on a second visit,
wherein 16 intramuscular injections are administered to separate injection sites on the second calf on the second visit, and
wherein each of the 64 intramuscular injections is performed with 0.25 mg of VM202 in a volume of 0.5 ml.
12 . A method of treating neuropathy by administering VM202, the improvement comprising:
selecting a patient with neuropathy who has been administered a gabapentinoid;
discontinuing gabapentinoid administration to the patient; and then
administering VM202 to the patient.
13 . A method of treating neuropathy, comprising the steps of:
determining whether a patient with neuropathy has been administered a gabapentinoid within the preceding week;
if the patient has been administered a gabapentinoid within the preceding week, discontinuing gabapentinoid administration to the patient, and thereafter administering VM202 to the patient; and
if the patient has not been administered a gabapentinoid within the preceding week, administering VM202 to the patient.
