Method of preventing and treating chemotherapy-induced alopecia
Compositions and methods for treating alopecia, particularly chemotherapy-induced alopecia, using oxidizers or oxidants, pro-oxidant compounds, or activators of P53. Compositions comprising organic peroxides such as, cumene hydroperoxide, tert-Butyl hydroperoxide (t-BHP), hydrogen peroxide, benzoyl peroxide are preferred. Compositions may be applied subcutaneously, percutaneously, or topically. Most preferably, the compositions are applied to a treatment area prior to a round of chemotherapy to prevent or reduce hair loss in the treatment area.
1. A method for reducing an amount of hair loss due to alopecia induced by a chemotherapeutic agent, the method comprising the step of:
providing a composition to a subject prior to the subject receiving a dose of the chemotherapeutic agent by applying the composition subcutaneously, percutaneously, or topically at or a near a treatment area on the subject;
wherein the subject does not have alopecia at the time of the providing step;
wherein the composition comprises benzoyl peroxide in an amount sufficient to provide a 0.1% to 15% w/w peroxide concentration based on a hydrogen peroxide equivalent peroxide value; and
wherein the benzoyl peroxide is the only active ingredient in the composition.
2. The method of claim 1 wherein the providing step comprises applying the composition percutaneously at or a near a treatment area on the subject; and
wherein the providing step is the only step in the method for reducing alopecia induced by a chemotherapeutic agent.
3. The method of claim 1 wherein the providing step comprises applying the composition topically; and
wherein the providing step is the only step in the method for reducing alopecia induced by a chemotherapeutic agent.
4. The method of claim 3 wherein the composition further comprises a carrier.
5. The method of claim 1 wherein the providing step comprises applying the composition subcutaneously; and
wherein the providing step is the only step in the method for reducing alopecia induced by a chemotherapeutic agent.
6. The method of claim 3 wherein the method reduces an amount of hair loss in the treatment area by at least 25% compared to an amount of loss in a second area of non-treatment that is similarly sized to the treatment area.
7. The method of claim 6 wherein the providing step comprises applying around 0.5 to 10% by weight of the benzoyl peroxide.
8. The method of claim 6 wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives the dose of the chemotherapeutic agent.
9. The method of claim 6 wherein the subject receives the dose of the chemotherapeutic agent multiple times over a period of time and wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives each dose of the chemotherapeutic agent.
10. The method of claim 9 wherein the chemotherapeutic agent comprises Vp-16, a taxane, Adriamycin, Cytoxan, cytosine arabinoside, or a combination thereof.
11. The method of claim 5 wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives the dose of the chemotherapeutic agent.
12. The method of claim 5 wherein the subject receives the dose of the chemotherapeutic agent multiple times over a period of time and wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives each dose of the chemotherapeutic agent.
13. The method of claim 3 wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives the dose of the chemotherapeutic agent.
14. The method of claim 13 wherein the subject receives the dose of the chemotherapeutic agent multiple times over a period of time and wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives each dose of the chemotherapeutic agent.
15. A method for reducing an amount of hair loss due to alopecia induced by a chemotherapeutic agent, the method comprising the step of:
providing a composition to a subject prior to the subject receiving a dose of the chemotherapeutic agent by applying the composition subcutaneously, percutaneously, or topically at or a near a treatment area on the subject;
wherein the composition comprises benzoyl peroxide in an amount sufficient to provide a 0.1% to 15% w/w peroxide concentration based on a hydrogen peroxide equivalent peroxide value; and
wherein the benzoyl peroxide is the only active ingredient in the composition.
16. The method of claim 15 wherein the providing step is repeated at least once per day for a treatment period comprising at least 3 days before the subject receives the dose of the chemotherapeutic agent.
17. The method of claim 15 wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives the dose of the chemotherapeutic agent.
18. The method of claim 1 wherein the providing step is repeated at least once per day for a treatment period comprising at least 3 days before the subject receives the dose of the chemotherapeutic agent.
19. The method of claim 1 wherein the providing step is repeated at least once per day for a treatment period comprising at least 7 days before the subject receives the dose of the chemotherapeutic agent.
20. The method of claim 1 wherein the benzoyl peroxide is in an amount sufficient to provide a 0.1% to 5% w/w peroxide concentration based on a hydrogen peroxide equivalent peroxide value.
