Description

METHOD FOR THE PREVENTION OR REDUCTION OF CARDIOVASCULAR EVENTS ASSOCIATED WITH CORONARY INTERVENTION
Field of Invention
The present invention relates to a method for the prevention or reduction of cardiovascular events associated with coronary intervention.
More particularly, the method comprises administrating to a mammal, particularly a human patient, after coronary intervention an oral or parental dose of N-(3',4 '- dimethoxycinnamoy anthranilic acid (N-51) (Tranilast) represented by the following formula (I) or a pharmaceutically acceptable salt thereof as an active ingredient.

BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
Coronary intervention is a percutaneous procedural approach to the treatment of ischemic heart disease such as angina pectoris and myocardial infarction. Coronary intervention technically involves mechanical revascularization of a stenosed lesion in a coronary artery by means of a balloon catheter, stent placement, an atherectomy catheter and the like. As a consequence, coronary intervention often causes restenosis due to damaged intima and media cells. Patients who experience restenosis may require revascularization procedures to correct the condition. Other cardiovascular events associated with coronary intervention include myocardial infarction and death.
Up to the present time, there has not been any effective drug for the prevention or reduction of cardiovascular events associated with coronary intervention.
2. DESCRIPTION OF THE RELATED ART
Tranilast is sold commercially as a drug for the treatment of allergic diseases, e.g., allergic bronchitis, allergic asthma, atopic dermatitis, and the like, based on the activity exhibited by the drug for inhibiting release of chemical mediators [The Journal of Allergy and Clinical Immunology, Vol. 57, No. 5, pp. 396-407, (1976)].
More recently, in Biochemical Pharmacology, Vol. 36, No. 4, pp. 469-474 (1987), it was reported that Tranilast inhibits fibroblast proliferation and collagen accumulation. United States Patent No. 5,385,935 (935) claims the use of Tranilast in the inhibition of restenosis associated with coronary intervention and indicates that a treatment period of at least three consecutive months is required for efficacy. The requirement of a three plus month treatment period was premised, in part, upon a publication in the Japanese College of Cardiology (1988), cited in the 935 patent. This publication discloses the treatment of patients subjected to the PTCA procedure with Tranilast in a daily oral dose of 300 mg for 30 consecutive days after the PTCA procedure. The clinical data obtained from this study did not indicate any significant efficacy for inhibiting a restenosis effect associated with the PTCA procedure at the tested dosage and duration.
The 935 patent demonstrated that an extended period of Tranilast treatment was effective for lowering the incidence of post-surgery restenosis associated with PTCA. It was found that dosing patients with Tranilast for a period of at least about three months (i.e., a term of at least about 90 consecutive days of treatment, as used herein the phrase "at least three consecutive months" means at least 90 days) reduced the incidence of restenosis associated with the PTCA procedure. In one clinical study, when patients were administered Tranilast in a daily oral dose of 600 mg for three consecutive months after the PTCA procedure, the incidence of restenosis was less than about 20%. As reported in the 935 patent, the incidence of restenosis associated with the PTCA procedure usually is about 40%. The 935 patent does not contain any disclosure regarding the ability of Tranilast to effect cardiovascular events as defined herein.
Additionally, in Nobuyoshi M. et al., J Am Coll. Cardiol. 1988; 12: 616 to 623, it was observed that most cases of restenosis after successful coronary angioplasty occur within 6 months after the procedure, particularly between 1 and 3 months after coronary angioplasty.
Notwithstanding, the percent diameter stenosis measurement is reported to correlate poorly with the physiologic significance of lesions (Harrison D.G. et al. Circulation 1984; 69:1111-9). Furthermore, because significant changes sometimes occur in the adjacent normal coronary segment after coronary angioplasty (Brayden G.P. et al. Clin. Res. 1983; 31: 702A), use of percent stenosis in a restenosis study has shortcomings. As such, a treatment that demonstrates efficacy in the prevention or reduction of restenosis does not correspond or lead one to anticipate with any degree of certainty that the treatment would have a beneficial or therapeutically significant effect on the prevention or reduction of cardiovascular events associated with coronary intervention.
Numerous advantages would be realized if Tranilast could be efficaciously administered for the prevention or reduction of cardiovascular events associated with coronary intervention. It has now surprisingly been discovered that Tranilast can be suitably administered in the prevention or reduction of cardiovascular events associated with coronary intervention.
