Definitions
- the present invention relates to a novel method for treatment of HIV infection by using an extract from inflammatory tissue inoculated with vaccinia virus. More particularly, it relates to a combined therapy for HIV infection with anti-HIV drugs and the extract.
- AIDS Acquired Immunodeficiency Syndrome
- HAV Human Immunodeficiency Virus
- HAART highly active antiretroviral therapy
- HAART can suppress the replication of HIV in an infected patient and can prevent the progress of HIV infection.
- the discontinuation of the chemotherapy at any time following injection causes a rebound in, and repopulation of, HIV.
- a patient is required to receive the chemotherapy continuously during most of his or her lifetime.
- anti-HIV drags have a large formulation.
- many drugs must be taken at each dosage.
- the anti-HIV drugs induce various and strong side effects. If a patient does not keep the dosage schedule very strictly, the treatment meets with failure by the induction of a drag-resistant virus.
- the pharmacological activities of an extract from an inflammatory tissue inoculated with vaccinia virus include: (1) analgesic, sedative, anti-stress and antiallergic effects (Japanese Patent Laid-Open No. Sho-53-101515); (2) immuno-enhancing, anti-cancer and hepatocirrhosis suppressive effects (Japanese Patent Laid-Open No. Sho- 55-87724); (3) therapeutic effect for idiopathic thrombocytopenic purpra (Japanese Patent Laid-Open No.
- An aspect of the present invention is to provide a method for treatment of
- HIV infection to offer an alternative to the problems associated with the long term use of anti-HIV drugs, such as the decrease of QOL of patients accompanied with therapy for HIV infection including AIDS, economical burdens, strong side effects of anti-retroviral drugs, and appearance of drug-resistant viruses.
- the present invention provides a novel adjunct method for the treatment of HIV to give persisting effectiveness to suppress HIV replication.
- the present inventors have conducted various studies regarding the suppression on HIV replication for the therapy of HIV infection. As a result, the inventors found that after viral loads are lowered by the administrations of an approved anti-HIV drug, the suppressive action on HIV replication can be maintained by the administration of an extract from inflammatory tissue inoculated with vaccinia virus, during a time period during which the conventional anti-HIV drugs are terminated.
- the present invention provides an alternative to continuous treatment of
- HIV-I infected patients with conventional FDA approved anti-HIV chemotherapeutic drug regimens.
- patients can be administered the conventional anti-HIV chemotherapeutic drugs until the level of HIV in the blood is reduced to below detectable levels. Thereafter, the patients can be administered pharmaceutically effective dosages of an extract prepared from tissues that have been previously injected with vaccinia virus and demonstrate readily observable inflammatory responses.
- the extract may be administered during and after treatment with at least one anti-HIV drag.
- the administration of the extract may be initiated just prior to or after termination of treatment with the anti-HIV drag to maintain substantially reduced viral load or viral level of HIV-RNA for an extended period of time even after termination of treatment IN THE UNITED STATES PATENT AND TRADEMARK OFFICE
- the administration of the extract may be initiated when the plasma viral level of HIV-RNA is lowered to less than a detectable limit by administration of the standard anti-HIV drug.
- the extract from the inflammatory tissue prepared from rabbit skin following vaccinia virus administration is combined with the standard anti-HIV drug such as a reverse transcriptase inhibitor to reduce treatment time with the standard anti-HIV drug.
- FIG. 1 shows a graph representing the levels of plasma viral loads in rhesus macaques without anti-HIV drug therapy after SIV infection.
- FIG. 2 shows a graph representing the levels of plasma viral loads in rhesus macaques with only the standard anti-HIV drug PMPA (9-R- (2- phophorylmethoxypropyl) adenine) therapy administered following SIV infection.
- FIG. 3 shows a graph representing the levels of plasma viral loads in rhesus macaques in which the administration of an extract from inflammatory tissue inoculated with vaccinia virus was initiated just before the termination of PMPA therapy after SIV infection.
- the suppressive action on HIV replication obtained by the administration of a previously approved anti- HIV drugs may be maintained by the administration of an extract prepared from inflammatory tissue of a rabbit inoculated with vaccinia virus.
- Approved anti-HIV drugs may cause various side effects and other problems and may not be administered continuously for a long term period of time.
- the suppressive action on HIV replication from the approved anti-HIV drugs may be maintained by administration of an extract from inflammatory tissue inoculated with vaccinia virus for a certain period following the reduction stage of virus level, even after the administrations of anti-HIV drugs are terminated.
- the extract may be administered: (1) after viral loads of HIV in the blood of a patient are lowered by administration of at least one anti-HIV drug, or (2) after the plasma viral level of HIV-RNA is lowered to less than a detectable limit by administration of at least one anti-HIV drug.
- the extract used according to the present invention is a safe drug having no problems such as the side effects observed in the anti-HIV drugs which are presently used. Therefore, the method of the present invention for treatment of HIV infection provides an effective alternative form of therapy to solve the problems noted above, such as the decrease of QOL of patients accompanied with the therapy for HIV infection including AIDS, economic burdens, strong side effects of anti-retroviral drugs, and the appearance of a drug-resistant virus.

- the resulting activated charcoal was mixed with water, adjusted to pH 10 with sodium hydroxide, stirred at 60 0 C for 1.5 hours and centrifuged to give a supernatant.
- the activated charcoals precipitated by centrifugation were mixed with water, adjusted to pH 11 with sodium hydroxide, stirred at 60 0 C for 1.5 hours and centrifuged to give a supernatant.
- Both of the supernatants obtained were combined and neutralized with hydrochloric acid to give an extract from inflammatory tissue inoculated with vaccinia virus. In the following pharmacological studies, the extract was adjusted to appropriate concentrations to be used.
- HIV infection according to the present invention, namely an anti-retroviral action, was conducted.
- the pharmacological study was performed to determine the effectiveness of an extract from inflammatory tissue inoculated with vaccinia virus to influence the levels of viral rebound in SIV (Simian Immunodeficiency Virus)-infected monkeys following a standard 28 day single cycle anti-retroviral drug therapy.
- SIV Sesimian Immunodeficiency Virus
- This pharmacological study included a total of 3 groups of rhesus macaques (Macaca mulatto) of Indian origin with 4 monkeys included in each group.
- Group 1 included the monkeys (Virus control) that were not treated by an anti-retroviral drug after SlVinfection.
- the monkeys in Group 2 received a single 28 day cycle of daily administration of an anti-retroviral drug.
- the monkeys in Group 3 were administered an extract prepared from inflammatory tissue inoculated with vaccinia virus following a single 28 day cycle of daily administratoin of the same anti-retroviral drug as Group 2 monkeys.
- the studies were performed as follows:
- the supernatant fluids were ultracentrifuged, and the resulting virus was purified on a sucrose gradient and then pelleted.
- the pelleted virus was then resuspended in 1.0 mL of PBS (phosphate buffered saline) and termed virus stock.
- the level of virus was determined and the level of replication competent virus was titrated. [0034]
- the stock virus was then diluted so as to contain approximately 200 AID 50
- PMPA (9-R- (2-phophorylmethoxypropyl) adenine) is the standard drug for anti-retro viral chemotherapy of SIV infected non-human primates.
- the monkeys of Group 2 (PMPA control) and Group 3 (Extract treatment) were subcutaneously administered with PMPA at a dose of 30 mg/kg daily for 28 days soon after they reached viral load set point and the levels of plasma viral loads was determined.
- PMPA administration at a dose of 30 mg/kg daily for 28 days was decided because it was previously determined to be an effective dose regimen that leads to a reduction of plasma and cellular viral loads to almost undetectable levels.
- Example 1 An extract from inflammatory tissue inoculated with vaccinia virus produced in Example 1 was administered to the monkeys of Group 3 (Extract treatment) to determine the effectiveness of the extract to influence the level of plasma viremia following the anti-retroviral drag therapy.
- the extract from inflammatory tissue inoculated with vaccinia virus was adjusted to the appropriate concentration and sonicated for 20 minutes at 60 0 C and filtered through a 0.45- ⁇ m filter. It was then administered subcutaneously at a dose of 3.3 NU/kg daily for 60 days initiated at 2 days prior to the termination of PMPA therapy and the level of plasma viral loads were continuously monitored.
- peripheral blood mononuclear cell PBMC 13 pharmacological study, and each peripheral blood mononuclear cell (PBMC) was isolated and cultivated for defining the optimal concentration of PHA (phytohemagglutinin) that induced the maximum proliferation of PBMC.
- PHA phytohemagglutinin
- the proliferation study of PBMC was performed using 20% of the optimal concentration of PHA in the presence of various concentrations of the extract from inflammatory tissue inoculated with vaccinia virus. Then, each concentration of the chemokine such as RANTES, MIP- l ⁇ or MIP- l ⁇ in the supernatant fluid of the culture was determined.
- the plasma viral loads after infection with SIV ranged from 100,000 to 10 million viral copies per mL at peak and then reached a set point 6-8 weeks post infection.
- the viral loads in Group 1 (Virus control) without any therapy at this point stayed at the set point (FIG. 1).
- PMPA therapy led to a marked reduction in plasma viral loads to between 100 to 1000 viral copies per mL by day 28 in Group 2 (PMPA control) and in Group 3 (Extract treatment).
- chemokines production such as RANTES or MIP- l ⁇ in the preserved plasma of the above monkeys was compared with the result of the above-mentioned infection study. Consequently, the increase of chemokines was observed along with the suppression of virus load in the plasma in the animal group showing significant viral suppression. As a distinct correlation regarding RANTES was confirmed in particular, the increase of RANTES was thought to be related to the suppression of virus.
- the production of chemokines differed in individual animals in the study to evaluate the response to chemokines production prior to the infection study.
- the suppressive action on HIV replication can be maintained by the administration of an extract from inflammatory tissue inoculated with vaccinia virus for a certain period following the achievement of reduced viral loads induced by the administrations of anti-HIV drags (i.e., the anti-HIV drags were only administered daily for 28 days).
- anti-HIV drags i.e., the anti-HIV drags were only administered daily for 28 days.
- HIV drags can be maintained by use of an extract from inflammatory tissue inoculated with vaccinia virus for a short term, which has no problems such as side effects observed in the usual anti-HIV drugs, the method of the present invention for treatment of HIV
