inhaled CGRP antagonist Preventive Migraine partner: Amgen?

MC on 9/9/19:
“we look at migraines the chronic space is growing rapidly with the new CGRP and we believe there's opportunities for renewed interest in acute treatment, and so our migraine will be progressing in the Tox studies very shortly, and we feel very strong about moving that forward as soon as possible.”
Erenumab and CGRP antagonists as a whole significantly reduce the average number of migraine days experienced in migraine sufferers. CGRP antagonists appear to significantly improve treatment outcomes in patients who suffer from episodic and chronic migraines. Erenumab is the first CGRP antagonist to be FDA approved for public use.
In early 2019, the FDA approved three CGRP monoclonal antibody drugs for the treatment of migraines. The medications are known by the brand names Aimovig, Ajovy, and Emgality. Migraine is a common medical condition, affecting as many as 37 million people in the US. Jun 25, 2019
Aimovig™ (erenumab) is an injectable human monoclonal antibody (mAb) co-developed by pharmaceutical companies Novartis and Amgen.
FDA has approved the calcitonin gene–related peptide (CGRP) antagonist galcanezumab-gnlm (Emgality, Eli Lilly and Co) for the prevention of migraine in adult patients.
FDA has approved the humanized monoclonal antibody fremanezumab-vfrm (Ajovy, Teva Pharmaceuticals) for migraine prevention in adults, the manufacturer has announced.
How are these drugs administered?
The first three of the treatments are going to be by patient self-injection with a subcutaneous auto-injector at home. Two of them will always be monthly, and one of them will be either monthly or quarterly self-injection. The fourth one is going to be available by an intravenous infusion, which will be given every quarter, but patients would have to come into the doctor’s office to receive the fourth one, which we would expect at the end of next year or in 2020.
How much relief can patients expect to receive?
For patients with episodic migraine, that is less than 15 headache days per month, the new drugs dropped the number of migraine days per month by two to four days, generally around four days. If you multiply four days per month of no migraine times 12 months, then you have 48 days of no migraine per year, that otherwise would have been migraine days. That’s roughly a month and a half of no migraine per year compared to no treatment.
For the chronic migraine patients, those who have headache 15 or more headache days per month, these drugs dropped the number of migraine days by six to eight days per month. Of course, people with chronic migraine have more headache days per month to begin with, but six to eight days per month multiplied by 12 means that people could be expected to have at least two and a half months of no migraine, even three months of no migraine per year that they previously had migraine. That’s a pretty dramatic drop in the number of days of no migraine in a year and per month. That’s why we’re very, very excited.
Are there any reasons, another question, for pre-existing health condition or another medicine that would prevent somebody from receiving the treatments?
Erenumab, the drug that was approved, has been studied in patients with angina and heart disease. In that study, there was no impact on the angina in patients with pretty frequent angina. Erenumab has also been studied in people with risk factors for coronary disease and vascular disease without problems noted. There don’t seem to be any drug interactions that we know of with these monoclonal antibodies and other treatments. People would still be able to use their acute treatments when a migraine breaks through because for most people, these are not going to completely eliminate migraines. They’re going to help with frequency, severity, and duration.

U.S. top court rejects Helsinn over anti-nausea drug patent in win for Teva
1/22/19
WASHINGTON (Reuters) - The U.S. Supreme Court on Tuesday refused to revive Swiss drug company Helsinn Healthcare S.A.'s patent on the lucrative anti-nausea drug Aloxi in a victory for Teva Pharmaceutical Industries, which launched a generic version of it last year.
The nine justices unanimously upheld a lower court ruling that had canceled Helsinn's patent on Aloxi for violating a provision in U.S. patent law that forbids sales of an invention before applying for a patent. Teva began selling its generic version of the drug in March 2018 after convincing the lower court to invalidate the patent.
Aloxi is used to prevent nausea and vomiting in patients receiving chemotherapy. The high court's decision comes after it previously refused Helsinn's request to block the lower court ruling while it considered the company's case, which allowed Israel-based Teva to bring its Aloxi generic to market.
The ruling could make it easier to cancel key patents, especially among smaller drugmakers, widening the patent law provision prohibiting the patenting of an invention if it has been on sale or offered to the public more than a year before the patent application was filed.
The dispute centered on a licensing and purchase agreement that Helsinn, a small, family-owned pharmaceutical company, struck with another pharmaceutical firm in 2001 to distribute the drug in the United States and defray its own costs. The deal had been announced in regulatory filings and a press release.
Teva said the patent was invalid because the deal was reached nearly two years before Helsinn first applied for a patent and constituted a public sale. Helsinn, backed by President Donald Trump's administration, said that the distribution deal did not constitute a sale to the public because its drug formulation was kept secret.
Helsinn sued in 2011 over Teva's plans for a generic version of Aloxi. In 2017, the U.S. Court of Appeals for the Federal Circuit, a Washington-based specialized patent court, agreed with Teva and invalidated the patent, finding that a commercial offer or contract to sell a product makes it available to the public.
Helsinn said the appeals court's decision hindered small companies that often need partners to develop and bring drugs to the market, and would dissuade them developing new medicines.
Before Teva's generic was launched, Aloxi accounted for hundreds of millions of dollars in annual sales for Helsinn, the "overwhelming majority" of its worldwide revenue, according to court filings
