Title:	Low concentration delivery of an ergoline derivative for treatment of a headache
Abstract:	Provided are ergoline derivative containing medicaments disposed within a preassembled, prefilled, single-use delivery device, methods for administering a medicament using a preassembled, prefilled, single-use delivery device, and systems or kits that contain one or more preassembled, prefilled, single-use devices and user instructions, such as for treatment of a migraine or other headache.
Inventor(s):	Ralph Solarski, Robert Edward Malone
Assignee:	Relevale Inc
Application Number:	US17/365,750
Patent Claims:	1. An ergoline derivative containing medicament comprising dihydroergotamine or a pharmaceutically acceptable salt thereof, wherein the medicament is disposed in an auto-injector device, the device comprising: a syringe containing the medicament; a hollow injection needle operably coupled to a distal end of the syringe; a dosing mechanism operably adjacent to a proximal end of the syringe; and a trigger mechanism operably coupled to the dosing mechanism, wherein the trigger mechanism, when actuated, causes the dosing mechanism to advance the syringe and the injection needle, discharging the medicament though the injection needle; and wherein the medicament comprises a pH of between about 3 and about 8; and wherein the ergoline derivative is present in a concentration range of about 0.3 mg/mL to about 1.5 mg/mL. 2. The ergoline derivative containing medicament of claim 1, wherein the ergoline derivative is dihydroergotamine mesylate. 3. The ergoline derivative containing medicament of claim 1, wherein the concentration of the ergoline derivative ranges from about 0.5 to about 1.4 mg/mL. 4. The ergoline derivative containing medicament of claim 1, wherein the concentration of the ergoline derivative is from about 0.8 to about 1.2 mg/mL. 5. The ergoline derivative containing medicament of claim 1, wherein the medicament further comprises one or more tonicity adjusting agents, buffers, antioxidants, stabilizers, nonionic wetting or clarifying agents, and/or viscosity modifiers. 6. The ergoline derivative containing medicament of claim 1, wherein the medicament comprises about 1.0 mg dihydroergotamine mesylate, about 49.0 mg ethanol, about 150 mg glycerin, about 800 mg water for injection, and a buffer comprising sodium hydroxide and/or methane sulfonic acid in an amount sufficient to adjust the pH of the medicament to between about 3.4 and about 4.9. 7. The ergoline derivative containing medicament of claim 1, wherein the medicament further comprises alcohol, glycerin, and water for injection. 8. A method of treating a headache in a person, comprising administering an ergoline derivative medicament using preassembled, prefilled, single use delivery device, the method comprising: placing the delivery device against an injection site; actuating a trigger mechanism of the delivery device, wherein the trigger mechanism, when actuated, causes a dosing mechanism of the delivery device to advance the syringe and the injection needle, and to discharge the medicament though the injection needle; and maintaining the delivery device against the injection site, while the injection needle penetrates the injection site, and the medicament contained in the syringe is injected though the injection needle into the injection site; wherein the medicament comprises a pH of between about 3 and about 8; and wherein the medicament comprises a concentration range of about 0.5 mg/mL to about 1.5 mg/mL of an ergoline derivative. 9. The method of claim 8, wherein the ergoline derivative medicament comprises dihydroergotamine or a pharmaceutically acceptable salt thereof. 10. The method of claim 8, wherein the ergoline derivative medicament comprises dihydroergotamine and/or dihydroergotamine mesylate. 11. The method of claim 8, wherein the medicament comprises a concentration range of about 0.5 mg/mL to about 1.4 mg/mL of an ergoline derivative. 12. The method of claim 8, wherein the medicament comprises a concentration range of about 0.8 mg/mL to about 1.2 mg/mL of an ergoline derivative. 13. The method of claim 8, wherein the concentration of the ergoline derivative is about 1.5 mg/mL. 14. The method of claim 8, wherein a dose of the ergoline derivative ranges from about 0.1 mg to 10 mg per injection. 15. The method of claim 8, wherein a dose of the ergoline derivative ranges from about 1 to about 2 mg per injection.
