An FDA Filing for Momenta’s Adalimumab Biosimilar Coming Soon?

Momenta seems to be in final preparations for its first 351(k) filing to the Food and Drug Administration (FDA). In its recent investor conference, the company disclosed that it is ready to send M923, its adalimumab biosimilar, to the agency for approval.

Despite this promising news, Momenta is facing strong headwinds. Even if it gains approval, Momenta expects that the US launch of the adalimumab biosimilar will not occur until 2023, owing to pending patent issues with Abbvie’s Humira®. The company does not yet have a marketing partner for this agent, though there appears to be plenty of time.

In addition, Momenta received a setback in November 2017 on another looming biosimilar candidate, when its biosimilar version of abatacept failed its phase 1 trial. Apparently, its M834 produced pharmacokinetic results that differed from the originator Orencia® in this early clinical study. Momenta is still studying the data and trying to come to grips with the surprising findings.

The company is also set to begin “pivotal” clinical trials on its other drug candidate M710, a biosimilar to aflibercept. The originator product is Eylea®, and it is indicated to treat wet age-related macular degeneration.

Momenta’s partnership with Mylan is moving forward with preclinical work on four other nonspecified biosimilars, according to the company. But all of this development costs money, and Momenta has acknowledged that it may need to raise cash for future development.

Momenta received approval in January for a generic form of the multiple sclerosis drug Copaxone® (glatiramer acetate). The approval of this agent, produced in partnership with Sandoz, had been delayed because of manufacturing issues. The company recognizes that the entry of Mylan (ironically) into this market may hinder its financial outlook.

As a result of these developments, Momenta stated it would entertain a sale of its adalimumab biosimilar “or other assets.”

 

The Patent Games: Another Sequel Underway

Roche/Genentech has filed suit in Delaware, citing the alleged violation of 37 patents by Amgen in its intent to market its biosimilar version of Herceptin®.  

The litigation was filed in response to Amgen’s stated intention of launching their product in October 2018, based on a May approval. Unfortunately, the Food and Drug Administration decided not to approve Amgen and Allergan’s initial 351(k) application in early June.

Roche has been engaged with Pfizer and the team of Celltrion and Teva on their trastuzumab biosimilars as well.

A Profile on Lesser-Known Player in the Biosimilar Space: Alteogen Inc

On occasion, we profile some biosimilar manufacturers about whom our readers may not be familiar. This generally refers to companies that have products that are in earlier-stage research or those who simply have not been in the news as often as their colleagues. In this post, we highlight a South Korean-based company, Alteogen Inc.

Established in 2008, Alteogen is focused on the development of bio-betters, with an emphasis on increased half-lives. It is a fairly new player in the biosiAlteogenmilar field, however, and has  partnered with Chinese, Japanese, and Brazilian companies to advance the development of at least two biosimilars.

 

 

 

Why you may be hearing more about this company: Its lead product, a biosimilar of aflibercept (originator product Eylea®) for the treatment of macular degeneration, has just completed preclinical testing. They have announced their intention to file this year with the US Food and Drug Administration to begin the clinical trial process of ALT-L9. Additionally, Alteogen is beginning the drug characterization process for a version of trastuzumab.

Whereas both agents are several years away from potential marketing, Alteogen believes that ALT-L9 may demonstrate some distinct advantages over Regeneron’s originator product. The manufacturer believes that potential benefits include better storage and transport characteristics, including longer dates to expiration and resistance to high temperatures. The company points to proprietary technology which may help it to achieve this “bio-better” status in the biosimilar space with trastuzumab. Its website says that using “an antibody drug conjugate technology conjugating the anti-cancer chemical drugs to an antibody protein… is a technology for the next generation anti-cancer therapeutics, which increase the effectiveness and reduces side effects of the anti-cancer cells directly.” It has applied this technology to trastuzumab, and this agent (ALT-02) has completed a phase 1 trial.
