Teva and Alexza Announce Teva’s License to Market ADASUVE® in the U.S.


Loxapine (LoxapacLoxitane)

is a typical antipsychotic medication, used primarily in the treatment of schizophrenia. It is a member of the dibenzoxazepine class and structurally related to clozapine (which belongs to the chemically akin class ofdibenzodiazepines). Several researchers have argued that Loxapine may behave as anatypical antipsychotic.

Loxapine may be metabolized by N-demethylation to amoxapine, a tetracyclic antidepressant.

Eritoran is an investigational drug for the treatment of severe sepsis, an excessiveinflammatory response to an infection. It is being developed by the Japanese pharmaceutical company Eisai Co. and administered intravenously as the sodium salteritoran tetrasodium.

In a phase III clinical trial, eritoran did not perform better than existing treatments for the treatment of sepsis

Eisai and Arena Pharmaceuticals have been given the go-ahead to launch their anti-obesity drug Belviq in the USA.


lorcaserin

may8, 2013

At long last, Eisai and Arena Pharmaceuticals have been given the go-ahead to launch their anti-obesity drug Belviq in the USA.

The US Food and Drug Administration approved Belviq (lorcaserin) last June chronic weight management in adults with a body mass index of 30 or greater, or adults with a BMI of 27 who have at least one weight-related condition such as hypertension, type 2 diabetes or high cholesterol.  However, the agency said at the time that Belviq be classified by the US Drug Enforcement Administration as a scheduled drug, ie its potential for abuse needed to be evaluated.

This has held up a launch but now the DEA has placed Belviq into Schedule IV of the Controlled Substances Act, which means that the treatment has a low potential for abuse. In 30 days time, Eisai will make the drug available and the launch will trigger a $65 million milestone payment to Arena.

Arena will manufacture Belviq at its facility in Switzerland, and sell finished commercial product to Eisai for a purchase price starting at 31.5% of the Japanese drugmaker’s annual net product sales. The price increases on a tiered basis up to 36.5% exceeding $750 million and Arena is also eligible to receive $1.16 billion in purchase price adjustment payments.

Belviq can now compete against Vivus’ Qsymia (phentermine/topiramate) which was launched in September but has had disappointing sales, hit by reimbursement issues. Qsymia is also classed as Schedule IV by the DEA.

The move is clearly very good news for Arena which last week withdrew its marketing application for Belviq this side of the Atlantic. The European Medicines Agency’s Committee on Human Medicinal Products has expressed its concerns over potential cardiovascular risks and worries about tumours found in animal studies.www.arenapharm.com

Lorcaserin (APD-356, trade name upon approval Belviq, expected trade name during development, Lorqess) is a weight-loss drug developed by Arena Pharmaceuticals. It has serotonergic properties and acts as an anorectic. On 22 December 2009 a New Drug Application (NDA) was submitted to the Food and Drug Administration (FDA) in the United States. On 16 September 2010, an FDA advisory panel voted to recommend against approval of the drug based on concerns over both safety and efficacy. In October 2010, the FDA stated that it could not approve the application for lorcaserin in its present form.

On 10 May 2012, after a new round of studies submitted by Arena, an FDA panel voted to recommend lorcaserin with certain restrictions and patient monitoring. The restrictions include patients with a BMI of over 30, or with a BMI over 27 and a comorbidity like high blood pressure or type 2 diabetes.

On 27 June 2012, the FDA officially approved lorcaserin for use in the treatment of obesity for adults with a BMI equal to or greater than 30 or adults with a BMI of 27 or greater who “have at least one weight-related health condition, such as high blood pressure, type 2 diabetes, or high cholesterol”.

On 07 May 2013, the US Drug Enforcement Administration has classified lorcaserin as a Schedule IV drug under the Controlled Substances Act.

PRECLINICAL- 4-quinolone prodrugs, pP4Q-414 , potential treatment of multi-drug resistant Plasmodium falciparum malaria


Medicines for Malaria Venture is investigating 4-quinolone prodrugs including pP4Q-414 (structure shown) and pP4Q-435, for the potential treatment of multi-drug resistant Plasmodium falciparum malaria.

In April 2013, data were presented at the 104th AACR Meeting in Washington DC. Of the compounds screened, pP4Q-414 and pP4Q-435 prodrug of P4Q-146 and P4Q-158 respectively, showed potent activity against P falciparum. In vivo, of the five mice evaluable, one mouse was cured with pP4Q-414 (at po 10 mg/kg) treatment and two of the five mice were cured with pP4Q-435 (at po 50 mg/kg) treatment

Ferring Pharmaceuticals begins phase III trials of elobixibat, a new investigational compound for chronic idiopathic constipation

ELOBIXIBAT

Ferring Pharmaceuticals begins phase III trials of elobixibat, a new investigational compound for chronic idiopathic constipation

 

Ferring Pharmaceuticals today MAY 2, 2013, announced it has initiated enrolment of patients in two phase III clinical trials of the investigational compound elobixibat for the treatment of chronic idiopathic constipation (CIC), a common gastrointestinal disorder affecting approximately 14% of the general population1. The two studies, Echo 1 and Echo 2, will be conducted at close to 200 sites worldwide and will enroll nearly 1700 patients. The studies aim to demonstrate the efficacy and safety of repeated daily doses of elobixibat against placebo over a period of up to 26 weeks.

Elobixibat is a first-in-class compound with a novel physiological mechanism of action. It acts locally in the gut with minimal systemic exposure to enhance the amount of luminal bile acids in the colon by a partial inhibition of the Ileal Bile Acid Transporter (IBAT). This potentially increases colonic fluid secretion and motility. Ferring acquired the global marketing rights for elobixibat, excluding Japan and a small number of Asian markets, from Albireo AB in 2012.

“We are pleased to begin Phase III studies on elobixibat for the treatment of chronic idiopathic constipation,” said Pascal Danglas, Executive Vice President, Clinical and Product Development at Ferring. “CIC causes significant discomfort to sufferers and seriously impacts their quality of life. Studies have shown that patients are not satisfied with current treatments.”

About chronic idiopathic constipation

Chronic idiopathic constipation (CIC) is among the most common diseases throughout the world, affecting approximately 14% of the general population particularly women and the elderly1. Patients with CIC often experience hard and lumpy stools, straining during defecation and a sensation of incomplete evacuation, as well as discomfort and bloating. CIC adversely affects a person’s quality of life and is associated with significant health care expenditure2. Studies show that nearly 50% of CIC sufferers are not satisfied with available treatments3 underscoring the unmet medical need in this area.

About Ferring Pharmaceuticals:

Headquartered in Switzerland, Ferring Pharmaceuticals is a research-driven, specialty biopharmaceutical group active in global markets. The company identifies, develops and markets innovative products in the areas of gastroenterology, reproductive health, urology and endocrinology. Ferring has its own operating subsidiaries in 50 countries and markets its products in more than 90 countries. To learn more about Ferring or its products please visit www.ferring.com.

Elobixibat is an IBAT inhibitor,[1] in clinical testing as of December 2012 for the treatment of chronic constipation and irritable bowel syndrome with constipation (IBS-C). It works by blocking the enterohepatic circulation of bile acids, increasing the bile acid concentration in the gut, which accelerates intestinal passage and softens the stool.

The drug was developed by Albireo AB, who licensed it to Ferring Pharmaceuticals for further development and marketing.[2][3]

Albireo has partnered with Ajinomoto Pharmaceuticals, giving the Japan-based company the rights to further develop the drug and market it throughout Asia.[4]
