Description

CANNABIDIOL FOR REDUCING A STEROID DOSE AND TREATING INFLAMMATORY AND AUTOIMMUNE DISEASES

[001] This application claims the benefit of priority from U.S. Patent Application No. 15/143,694, filed on May 2, 2016. The content of the above document is incorporated by reference in its entirety as if fully set forth herein.

FIELD OF INVENTION

[002] The present invention relates to methods and uses of Cannabidiol compositions in reducing a steroid dose and treating inflammatory and autoimmune diseases and conditions.

BACKGROUND OF THE INVENTION

[003] Steroids such as corticosteroids are useful in the management of many inflammatory diseases such as asthma for more than 50 years. Regardless of the route used, it is advisable to limit the use of these agents to patients who clearly require them and to take all precautions to minimize side effects.

[004] There is ample evidence that the HPA axis function is suppressed by exogenous corticosteroids.

[005] Several investigators have found that some patients receiving daily doses >5 mg prednisone (or of other corticosteroids in equivalent pharmacologic doses) for months to years have evidence of suppression of HPA function. This inhibition of adrenal function in the presence of stress, e.g., surgery, severe trauma, or a serious illness, may cause circulatory collapse and death if not promptly treated with supplemental hydrocortisone. As in status asthmaticus, the precise amount of hydrocortisone has not been clearly delineated and various regimens have been proposed. [006] Intravenous supra-pharmacological doses of corticosteroids are used in various inflammatory and autoimmune conditions because they are cumulatively less toxic than sustained steroid treatment at lower quantitative dosage. Their action is supposed to be mediated through non-genomic actions within the cell. Common indications for use in children include steroid resistant and steroid dependent nephrotic syndrome, rapidly progressive glomerulonephritis, systemic vasculitis, systemic lupus erythematosus, acute renal allograft rejection, juvenile rheumatoid arthritis, juvenile dermatomyositis, pemphigus, optic neuritis, multiple sclerosis and acute disseminated encephalomyelitis. Methylprednisolone and dexamethasone show similar efficacy in most conditions. Therapy is associated with significant side effects including worsening of hypertension, infections, dyselectrolytemia and behavioral effects. Adequate monitoring is essential during usage.

[007] Glucocorticoids exert a variety of immunosuppressive, anti-inflammatory and antiallergic effects on primary and secondary immune cells and tissues. Studies have shown that the cellular effects of glucocorticoids are mediated by genomic and various nongenomic mechanisms.

[008] Within the cell, glucocorticoids form complexes with specific cytosolic glucocorticoid receptors (cGCR) which is a multiprotein complex containing several heat- shock proteins (hsp70 and hsp90), and has a zincfinger motif needed for transcription function. The cGCR also interacts with immunophilins, cochaperones such as p23 and src, and several kinases of the mitogen-activated protein kinase (MAPK) signaling system. The activated glucocorticoid receptor complex moves to the nucleus, binds as a homodimer to a specific DNA sequences in the promoters of the genes that it will affect (glucocorticoid responsive elements, GRE), and activates transcription factors, thus causing inhibition or induction of transcription, translation and finally the synthesis of specific regulator proteins. [009] Induction of transcription via positive GRE i s termed "transact vati on" . Inhibition of transcription can occur via direct interaction between the GCR and negative GRE, or, transcription factors can be displaced from the positive GRE through direct protein-protein interaction between transcription factors and the GCR. These direct positive and negative gene modulations affect proteins like cytokines, chemokines, inflammatory enzymes and adhesion molecules, resulting in modification of inflammation and immune response mechanisms.

[010] In another genomic mechanism termed "transrepression", monomers of the glucocorticoid/GCR complex directly or indirectly interact with transcription factors. One example is the induction of synthesis of IkB, which decreases the amount of the proinflammatory transcription factor NF-κΒ that could translocate to the nucleus and activate transcription of genes for IL-1, IL- 6, and TNF-a.

[011] At high concentrations, glucocorticoid molecules intercalate into cell membrane, which alters cellular functions by influencing cation transport via the plasma membrane and by increasing the proton leak of the mitochondria. These result in reduced calcium and sodium cycling across plasma membranes of immune cells, which is thought to contribute to rapid immunosuppression and a subsequent reduction of the inflammatory process. Glucocorticoid receptors have been found to be expressed on cell membranes of human cells (mGCR); mGCR-mediated mechanism may be involved in the rapid induction of apoptosis, and induction of lipomodulin, which inhibits production of prostaglandins and leukotrienes.

[012] The immunosuppressive clinical effects observed when high dose glucocorticoids are administered intravenously occur too rapidly to be explained by the classic (genomic) mechanism of action alone. Evidence suggests that high in vivo levels of steroids obtained by pulse corticosteroid therapy have qualitatively different pharmacologic effects than those produced at lower doses . High doses of glucocorticoids have been shown to inhibit NFkappaB action (transrepression) only at concentrations within the cell obtainable by the highest oral or intravenous doses.30 Buttgereit et al have postulated 3 "modules" of glucocorticoid effect on cells resulting from different concentrations: (i) low concentrations mediate effects via genomic events; (ii) medium concentrations bind as well to cell surface receptors, which activate cross membrane signal transmission for genomic and nongenomic intracellular events; and (iii) at very large concentrations steroids dissolve in the cell membrane resulting in greater membrane stability and reduced non-genomic cell function generally.

[013] A single glucocorticoid application at a high dose has a strong effect due to 100% saturation of cytosolic receptors; however, the effect would last only for a short period because receptor occupation rapidly reverts to the original value unless a new dose is given. Therefore, a single high dose is unlikely to have sustained effect. Overall, the effects of corticosteroid pulses appear to include downregulation of activation of immune cells and proinflammatory cytokine production, leading to reduced expression of adhesion molecules and reduced movement of neutrophils into sites of inflammation. These effects are qualitatively like those seen with anti-TNF-alpha therapy.

Example 1: treating autoimmune Hepatitis with reduced steroid dose

[0150] Forty-one (41) patients over 18 years of age suffering from autoimmune Hepatitis with no signs of remission are recruited. Patients having history of psychosis or asthma, or consuming Cannabis during the last two months before the study are excluded from the study. 15 of the patients had Jaundice.

[0151] All patients are receiving standard treatment consisting of prednisolone in a daily dose of 40 to 60 mg/day.

[0152] On the first two weeks of trial all patients are receiving prednisolone monotherapy.

[0153] On the third week of trial all patients are receiving CBD (STI Pharmaceuticals, Brentwood, Essex, UK) dissolved in olive oil at a concentration of 2.5% and (oral) at a dose of 75 mg CBD twice a day together with prednisolone at a dose reduced by 30%.

[0154] On the fourth week of trial all patients are receiving CBD (STI Pharmaceuticals, Brentwood, Essex, UK) dissolved in olive oil at a concentration of 2.5% and (oral) at a dose of 100 mg CBD twice a day together with prednisolone at a dose reduced by 50% from the initial dose of 40 to 60 mg/day.

[0155] On the fifth week of trial all patients are receiving CBD (STI Pharmaceuticals, Brentwood, Essex, UK) dissolved in olive oil at a concentration of 2.5% and (oral) at a dose of 150 mg CBD twice a day together with prednisolone at a dose reduced by 65% from the initial dose of 40 to 60 mg/day.

[0156] During the first two weeks 75% of the patients are suffering from at least one prednisolone specific side effects. [0157] During the third week 62% of the patients are suffering from at least one prednisolone specific side effects. During the fourth and the fifth weeks there is a steady decline in the number of patients suffering from at least one prednisolone specific side effects to 53% and 36%, respectively. [0158] Importantly, no side effects due to the use of CBD are reported. On the fifth week sign of remission are appearing in 68% of the patients with normalization of aminotransferases and immunoglobulin G. These signs of remission are attributed to the steroids and not to CBD.

[0159] After total remission, the present dual CBD and low-dose steroid therapy is continued as maintenance therapy for 18 to 30 months.

[0160] These results are indicating that administration of Cannabidiol reduces the severity of steroids' side effects due to a substantial increase in the potency of a lower dose of steroid once administered with Cannabidiol. Unlike dual therapy with Azathioprine, CBD is not showing any side-effects within the current daily doses. This finding is utmost important as CBD-steroid treatment unlike azathioprine-steroid treatment is free of side effects such as: cholestatic hepatitis, pancreatitis, arthralgias, fever, vomiting, nausea, emesis, rash, opportunistic infection bone marrow suppression and malignancy which are attributed to the use of azathioprine.

[0161] Moreover, CBD unlike Azathioprine unexpectedly and dramatically reduces steroidal side effects. Example 2: Cannabidiol (CBD)/steroid for treatment of severe UC

[0162] A 42 years old male with severe relapse of Ulcerative colitis (UC) is refractory to both high-dose of oral prednisone and intravenous hydrocortisone cyclosporine for 14 days.

[0163] The patient is immediately starting dual daily treatment of 70 mg prednisone and 250 mg oral CBD. After 6 days of dual CBD/prednisone therapy the patient is in complete cessation of diarrhea, abdominal pain and fever.

Example 3: Cannabidiol (CBD/steroid for treatment of erythroderma)

[0164] A 35 years old female with is afflicted with severe erythroderma, confirmed by skin biopsy. The patient is now 10 days refractory to twice daily Triamcinolone topical treatment and complains of severe skin blistering and burning.

[0165] The patient is immediately starting dual daily treatment of once daily topical Triamcinolone and 300 mg oral CBD. After 5 days of dual CBD/ Triamcinolone therapy the patient is relieved of any steroidal side effects with dramatic remission in erythroderma.

Example 4: Cannabidiol (CBD) renders a refractory high dose of steroids and tacrolimus -effective

[0166] 63 years old female with hepatitis developed jaundice with bilirubin level of 4.2 mg%. She started tacrolimus and high-dose steroids- prednisone, and had a partial response for a short period of time. Two months later, while still given tacrolimus and steroids she developed pancreatitis and had an upsurge in bilirubin to 8.5 mg%. [0167] She started oral CBD 150 mg BID. Jaundice resolved gradually and bilirubin dropped to normal levels. Steroids could be tapered off by 50% to a low dose of 7.5 mg QD with no CBD and or steroidal side-effects.

Example 5: Cannabidiol (CBD) renders an ineffective dose of Dexamethasone - effective

[0168] 68 years old female with Rheumatoid Arthritis (RA) developed pericarditis with sudden flares of joint pain. She is immediately treated for 14 days with Dexamethasone (4 mg orally every 12 hours) with only slight improvement of joint pain and developed anemia.

[0169] She's is immediately prescribed with oral CBD 150 mg BID and the daily dexamethasone dose is decreased to 3 mg orally every 12 hours. After 10 days from the beginning of treatment the patient is relived of burning joint pain and no signs of anemia are apparent, Dexamethasone is further reduced to 2 mg orally every 12 hours. After 14 days from the beginning of treatment the patient is still relived of burning joint pain and walks more comfortably, Dexamethasone is further reduced to 1.5 mg orally every 12 hours.

Example 6: Cannabidiol (CBD) renders a refractory high dose of Prednisone - effective

[0170] A 58 years old male with refractory follicular lymphoma underwent an allogeneic hematopoietic cell transplantation. One month later he was admitted with severe late onset acute skin inflammation and upper (nausea and vomiting) plus lower gastrointestinal involvement (bloody diarrhea, crampy abdominal pain and severely inflamed and ulcerated mucosa).

[0171] He started high-dose steroids (Prednisone). Despite skin response, GIT inflammation was refractory to prolonged systemic treatment of steroids. [0172] He started oral CBD 150 mg BID, symptoms improved gradually and a very good partial response (VGPR) was attained to the steroids. Prednisone was tapered off to 20 mg QD (40%)- found to be therapeutically effective.

[0173] The present CBD treatments, unexpectedly, rendered a dangerously high dose or a refractory dose of a steroid-therapeutically effective with minimal to no steroid side effects.
