Otsuka Pharmaceutical Co., Ltd. Key Developments

Otsuka Pharmaceutical Co., Ltd.’s JINARC Treatment Approves in Europe for Adults Living with ADPKD

Otsuka Pharmaceutical Co., Ltd. announced that the European Commission has granted marketing authorization for JINARC for the treatment of ADPKD in adults who have chronic kidney disease stage one to three at initiation of treatment with evidence of rapidly progressing disease. In receiving this marketing authorisation, tolvaptan becomes the first pharmaceutical therapy to be licensed in Europe for the treatment of the underlying pathophysiology of ADPKD. The marketing authorisation for tolvaptan is based on the findings of the pivotal Phase III randomised, double-blind and placebo-controlled TEMPO 3:4 trial the large clinical study conducted in ADPKD to date.1 In the three-year study, the rate of TKV increase over 3 years was significantly less for tolvaptan-treated subjects than for subjects receiving placebo: 2.80% per year vs 5.51% per year, respectively in ADPKD. Tolvaptan is a potent vasopressin V2 receptor antagonist that has been proven to slow cyst growth and renal function decline in patients with ADPKD in CKD stage one to three with evidence of rapidly progressive disease. The formation of cysts associated with ADPKD can lead to significant kidney damage, even when kidney function is not affected10 and cause complications that include chronic and acute pain, hypertension and kidney failure. In addition to the physical symptoms, ADPKD causes a profound psychological and emotional burden for those living with the disease, their families and loved ones. By selectively blocking vasopressin from its V2 receptor, tolvaptan decreases cyst cell proliferation and fluid secretion, ultimately reducing cyst development and renal clinical events associated with disease progression.

One pack contains three drugs for the first eradication of H. pylori, namely, TAKECAB® (generic name: Vonoprazan fumarate, hereinafter “TAKECAB”) — developed by Takeda for treating acid-related diseases through a novel mechanism of action using potassium-competitive acid blockers (P-CABs) — amoxicillin (Japanese brand name: AMOLIN®), and clarithromycin (Japanese brand name: Clarith®). Another contains three drugs for the second eradication of H. pylori, namely, TAKECAB, amoxicillin, and metronidazole (Japanese brand name: Flagyl®).
