Udenyca to Launch January 3, Same WAC as Mylan’s Fulphila

Coherus Biosciences surprised many on its third-quarter earnings call late yesterday. It will rely not on a lower price than its biosimilar competitor to gain marketshare after Coherus’ Udenyca launch, but on its ability to pull through on its patient and provider services and supply chain to gain significant marketshare for its biosimilar version of Neulasta®.

This is not to imply that Coherus will not offer contracts to group purchasing organizations (GPOs), hospitals, and payers.  The company intends to do so. However, the wholesale acquisition cost (WAC) for Udenyca® will match that of Mylan’s Fulphila®—$4,175 per vial, or a 33% discount from Amgen’s reference product. Denny Lanfear, CEO of Coherus added that the company’s contracting plans “will deliver additional value to payers.”

AWAITING HCPCS CODING

Unlike other biosimilar manufacturers, this is their first product to reach the market. Not only was manufacturing and production a priority, but company infrastructure had to be ready for launch. Although Coherus pointed out that the sales force for Coherus is fully in place, they are holding back the Udenyca launch until the Center for Medicare and Medicaid Services (CMS) designates a Q code for claims and billing purposes. Therefore, the goal is a Udenyca launch date of January 3, 2019.

Jim Hassard, Vice President for Marketing and Market Access, emphasized that “Our overall launch strategy goes beyond pricing, to reliable supply and services. We’re committed to world-class execution and salesforce effectiveness.” The company’s Coherus Complete, patient and provider service site, is operational, and this will include copay support for eligible patients. Mr. Hassard stated, “This price is attractive to payers without diminishing our value proposition. We can deliver significant savings to the health system versus Neulasta.”Coherus Biosciences

CAN UDENYCA GRAB SOME ONPRO MARKETSHARE?

One interesting statement made during the call was the expectation that Coherus will go after some of Neulasta Onpro’s share of the market. Amgen’s on-body injector accounts for about 60% of all Neulasta utilization today, “but this growth has flattened out,” Chris Thompson, Vice President of Sales, emphasized. “We’re looking at the whole market, not just prefilled syringe market,” he said. “We think we’ll be able to sell through the Onpro market,” meaning that their pricing and services will attract some of this marketshare. In fact, Coherus executives believe that biosimilars may eventually garner nearly 70% of the pegfilgrastim market.

Coherus believes that there is pent-up demand for the biosimilar in the hospital segment today, which is why GPOs may represent promising contracting opportunities. They are seeking parity positioning at the payer and pharmacy benefit manager level.

This sounds fairly reasonable. Yet the vast majority of biosimilar consultants and payers with whom I had communicated had anticipated that Coherus would launch with at least a modest WAC discount relative to Mylan’s Fulphila. On the conference call, the investment banking participants wanting information on the Udenyca launch seemed caught off guard as well.

UDENYCA REVENUE TO SUPPORT COHERUS FOR NOW

Perhaps this strategy gives Coherus ample room for contracting while retaining a respectable net cost. Mr. Thompson said, “We’ll roll out a comprehensive contracting strategy for GPOs in the next week or two. It will be competitive and designed to win.”

It may need to be. Relying on better services and perhaps even a better supply chain (albeit one that is brand new) may not be sufficiently persuasive to hospital and payer P&T Committees. And Coherus needs to generate revenue from its sole product to feed its new sales team, new product development, and hungry investors.

Coherus Gets FDA Approval for Its Pegfilgrastim Biosimilar

With the Food and Drug Administration (FDA) approval today of Coherus Bioscience’s Udenyca™ (pegfilgrastim-cbqv), the second pegfilgrastim to compete with Amgen’s Neulasta®, much attention will be now focused on the company’s November 8 earning call.

The FDA approved Udenyca on the basis of a supportive analytical similarity package, but with phase 1 data only. Over 600 healthy subjects were given the agent to test its pharmacokinetic, pharmacodynamic, and immunogenicity safety.

We should learn a great deal by the end of the week about the nature of the competition for the injectable pegfilgrastim marketplace into 2019. In the press release announcing the approval, the company said it will reveal its launch plans, including pricing, during its week’s call. On Monday, November 5, we should hear the first information about whether Mylan’s first-to-market entry, Fulphila®, has gained some traction against the injectable form of Neulasta. Mylan launched Fulphila at the end of July.

In a previous post, we discussed how Amgen’s Neulasta Onpro® patch has already captured upwards of 80% of the pegfilgrastim business. Because of the convenience of the patch formulation, it would be surprising if Onpro’s share of market eroded significantly. However, Amgen must ensure that the net cost difference between the biosimilars and Neulasta Onpro is not noteworthy. Otherwise, payers’ can be expected to try to disadvantage Onpro through step edits or greater patient cost sharing. That would take a sizable bite out of Amgen’s large slice of the $4 billion pegfilgrastim pie.

The FDA approved Udenyca for the following indication: to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia. It was not approved for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation. This indication language does not differ from that for Fulphila. Neulasta has the additional indication of increasing survival in patients acutely exposed to myelosuppressive doses of radiation.

Undenyca was also approved for sale in the EU, although Coherus has not launched there, awaiting a marketing partner.

Fresenius Kabi and Celltrion Get Good News

A German manufacturer is considering its options after the successful completion of two clinical studies involving a pegfilgrastim biosimilar (MSB11455).

Fresenius Kabi, which completed its purchase of the biosimilar business from Merck KGaA in September 2017, announced its investigational biosimilar agent had proved sufficiently similar to the reference product Neulasta® in these phase 1 investigations (conducted in healthy participants). These may serve as pivotal investigations for the manufacturer, which said in its release, “Both studies are designed to enable the application for marketing authorization in the EU and US.” This may be the first indication that Fresenius Kabi seeks to be a player in the US.

Fresenius Kabi does not yet have an approved biosimilar on the European market. It hopes that MSB11455 may propel its fortunes on both sides of the Atlantic.

Food and Drug AdministrationIn its first study, the company reported that its biosimilar “met all primary pharmacokinetic endpoints, [maximum plasma concentration], and area under the curve, as well as the primary pharmacodynamic endpoints of absolute neutrophil count (ANC).” Fresenius Kabi added that there were no meaningful differences in the frequency of adverse events in these healthy volunteers. The second study focused on the biosimilar’s potential for immunogenicity, and this was also determined to be no different between the reference drug and the biosimilar. In addition, neutralizng antibodies were not found.

If Fresenius Kabi proceeds with an application for approval in either market, it will find a good deal of competition for pegfilgrastim biosimilars. In Europe, up to 5 biosimilars may be approved (2 already are). In the US, Mylan’s product is the only one to be approved, but another (Coherus Biosciences) is expecting a decision from the Food and Drug Administration (FDA) in early November. Two others (Sandoz and Apotex) are seeking US drug approval.

In other biosimilar news…The Food and Drug Administration’s Oncology Drug Advisory Committee voted unanimously (16-0) today to recommend Celltrion’s CT-P10 rituximab biosimilar for approval. If the biosimilar is approved by the FDA, it will be marketed by Teva….Mundipharma purchased European biosimilar maker Cinfa, which has a pegfilgrastim that has received a CHMP recommendation for approval in the EU.

Tidal Wave of Pegfilgrastim Biosimilars About to Hit Europe

We had mentioned the upcoming deluge of adalimumab biosimilars aiming to hit the European market in mid-October, but another biosimilar tidal wave may actually precede this.

The European Medicines Agency (EMA) has had an extremely busy week in the pegfilgrastim biosimilars arena. In addition to granting marketing authorization to Coherus Biosciences for its pegfilgrastim biosimilar, it has also approved the marketing of Pelgraz®, a pegfilgrastim produced by Accord Healthcare. In addition, the EMA’s Committee for Medicinal Products for Human Use has also recommended approval for three pegfilgrastim biosimilars—from Sandoz, Cinfa, and Mylan.

Mylan is the only drug maker with a marketed biosimilar version of pegfilgrastim in the United States. Its product Fulphila® hit the US market in early July. Coherus’ product, Udenyca™, is awaiting a November 2 decision from the Food and Drug Administration. Coherus is reportedly looking for a partner to market its pegfilgrastim biosimilar overseas, while it intends to market the product internally in the US. This means that Accord may have the first pegfilgrastim biosimilar to reach patients in the EU, though this advantage will be short lived should Mylan in particular gain approval.

In other biosimilar news…Boehringer Ingelheim announced positive results in its clinical study of Cylteza® versus Humira® in patients with moderate-to-severe plaque psoriasis. The study results were announced at the European Society of Dermatology and Venereology.

Samsung Bioepis Co., Ltd. announced that the FDA has accepted its 351(k) application for SB5, a biosimilar to adalimumab. Samsung is the fourth manufacturer seeking to enter the biosimilar market for Humira. Two have been approved (Amjevita® by Amgen and Cyltezo® by Boehringer Ingelheim) but are not yet marketed. A decision on Sandoz’s application is expected later this year.

Mylan Rethinking Its US Business Strategy?

In reporting lower earnings on its second-quarter revenues, Mylan may have surprised industry observers by offering the possibility of some changes in strategic direction. Although Mylan executives sounded hopeful notes on the company’s biosimilar portfolio, the hints CEO Heather Bresch provided may affect the marketing of the biosimilars as well as its other pharmaceutical business.

Mylan CEO
Heather Bresch

Chief Executive Officer Heather Bresch said that Mylan’s generic drug business was the main reason for the declines in overall revenues, with adjusted gross profit from US business down 6% from the previous quarter last year. Sales revenues from North America as a whole were down 22% compared with an increase of 10% for the rest of the world.

On a conference call to announce the earnings, she noted that “our efforts to serve patients in the U.S. have been shaped by the industry’s transformation there, and our results and guidance for 2018 are directly correlated with the ongoing rebasing of the US healthcare environment.”

According to Rajiv Malik, President of Mylan, “This past quarter, Mylan continued to execute on its commitment to expand access to medicine through the advancement of our complex product portfolio across our global diversified platform. For example, we launched Fulphila™, our pegfilgrastim biosimilar, in the US, and CHMP issued a positive opinion for our biosimilar of Humira in Europe.”

The Board of Directors released its own statement, however, indicating that it may take a number of actions that could dramatically change the picture (though not specified, these could include selling off assets, seeking a merger, or restructuring the organization). In a press release, the Board said, “we believe that the US public markets continue to underappreciate and undervalue the durability, differentiation and strengths of Mylan’s global diversified business, especially when compared to our peers around the globe. Therefore, while we will continue to execute on our best-in-class, long-term focused sustainable strategy, the Board has formed a strategic review committee and is actively evaluating a wide range of alternatives to unlock the true value of our one-of-a-kind platform. The Board has not set a timetable for its evaluation of alternatives and there can be no assurance that any alternative will be implemented.”

Observers will be greatly interested in how Fulphila performs in the third quarter and beyond, particularly around the deep discount offered by Mylan. This could be a considerable shot in the arm to Mylan’s US revenues or simply a ratification of its opinion that the US health system is incentivized by higher prices.

 

Mylan’s Fulphila Pegfilgrastim Biosimilar Launches at Big Discount

The first pegfilgrastim biosimilar Fulphila Pegfilgrastim Biosimilar Launchedlgrastim (Fulphila™) in the US has begun marketing, and Mylan/Biocon are offering a 33% discount to the wholesale acquisition cost (WAC) of the originator product Neulasta®. The Center for Biosimilars reported a communication from Mylan confirming the action. This is a watershed moment for the pegfilgrastim category and could signal the beginning of large savings opportunities for payers and patients.

At a WAC of $4,175 per syringe, the pegfilgrastim biosimilar may be very attractive to health plans and insurers. It is also assumed that this will effectively drive down the average sales price (ASP) of the category over time. The ASP includes the WAC as well as any rebates or discounts given by the manufacturers.

The pegfilgrastim biosimilar, like the reference drug, Amgen’s Neulasta, is approved to decrease the incidence of infection as manifested by febrile neutropenia in patients receiving myelosuppressive chemotherapy.

Although patent litigation between the partners and the maker of the originator product (Amgen), Mylan/Biocon have decided to launch at risk. This means that if the District Court sides with Amgen, Mylan’s could face large financial penalties, including profits on the sales of the biosimilar.

Pfizer Gets FDA’s Green Light on Its Filgrastim Biosimilar

On July 20, the US Food and Drug Administration (FDA) approved the second biosimilar version of filgrastim. Pfizer’s filgrastim biosimilar is named Nivestym™ (filgrastim-aafi).

The originator product, Amgen’s Neupogen®, has steep competition from two other products (Sandoz’s Zarxio® [filgrastim-sndz] and Teva’s Granix® (tbo-filgrastim]). Granix was approved as a follow-on biologic, before the biosimilar pathway was implemented.

The FDA granted Nivestym the following indications:

  • To decrease the incidence of infection, as manifested by febrile neutropenia, in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a significant incidence of severe neutropenia with fever.
  • For reducing the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML).
  • To reduce the duration of neutropenia and neutropenia-related clinical sequelae, e.g., febrile neutropenia, in patients with nonmyeloid malignancies undergoing myeloablative chemotherapy followed by bone marrow transplantation (BMT).
  • For the mobilization of autologous hematopoietic progenitor cells into the peripheral blood for collection by leukapheresis.
  • For chronic administration to reduce the incidence and duration of sequelae of severe neutropenia (e.g., fever, infections, oropharyngeal ulcers) in symptomatic patients with congenital neutropenia, cyclic neutropenia, or idiopathic neutropenia.

Although a launch date was not announced for Pfizer’s filgrastim biosimilar, the company’s press release stated that “Nivestym is expected to be available in the US at a significant discount to the current wholesale acquisition cost (WAC) of Neupogen.”

Rather than competing aggressively for the filgrastim market, Amgen seems to be focusing its efforts on its pegfilgrastim brand, a longer-lasting version. Specifically, it is seeking to move its utilization to the Onpro formulation of Neulasta®. The first biosimilar to pegfilgrastim was approved in June (Mylan and Biocon’s Fulphila™).

Mylan and Biocon Land First Pegfilgrastim Biosimilar Approval

The race to bring a pegfilgrastim biosimilar to market officially started on December 17, 2014. The checkered flag fluttered 3½ years later on June 4, 2018, with the Mylan/Biocon team winning on a slow track. The partners earned approval from the US Food and Drug Administration (FDA), becoming the first biosimilar to challenge for this $4 billion market.

Mylan will market the product in the US, and it is assumed that the product will be launched shortly,= to take advantage of their window of opportunity. The drug will be called Fulphila™, and the FDA assigned a formal name of pegfilgrastim-jmdb. The next likely competitor, Coherus, is expected to receive word from the FDA by November 2. Mylan will have the chance to quickly grab marketshare if they produce attractive deals for payers.

Convincing Two Main Providers the Key to Pfizer’s Retacrit® Success

An unusual market situation awaits Pfizer’s new biosimilar epoetin, one that few approved medications has to face. Not only does Retacrit® need to pass muster with payers like health plans and insurers, which we assume it will, but Retacrit will need to be accepted by the two 800-pound gorillas of the kidney dialysis field as well.

epoetin use in kidney centersRetacrit and Dialysis Centers

The different part of this discussion is that providers are not usually so concentrated except in the treatment of the rarest diseases. Cancer medications are utilized by independent treatment centers throughout the country. Biosimilar agents like infliximab are also used throughout the nation by hospitals, large medical groups, and solo practices. In the case of epoetin, its primary use is in anemia related to kidney dialysis. The vast majority (85%) of kidney dialysis centers are owned by one of two networks, Fresenius Medical Care North America and DaVita Kidney Care. According to a report by Healio, Fresenius accounted for 42.6% of the total patient market in 2017, and DaVita is just behind, with 42.0% of the 453,000 patients receiving dialysis services. In other words, get buy-in from these companies and the payers, and Pfizer would have a chance to gain significant share of the epoetin market.

Nephrologists seem to be onboard, in general. The results of national survey of nephrologists conducted in March 2018 confirm this. According to the research, only one in five respondents would be averse to switching to the biosimilar. One barrier to use may exist, however, on the provider side. The long-acting agents may be preferred by some. These include Amgen’s darbepoetin alfa (Aranesp®) and Roche’s Mircera® (methoxy polyethylene glycol-epoetin beta). To the extent that nephrologists may be less willing to use short-acting biosimilar instead of the more expensive long-acting brand may define Pfizer’s success with Retacrit. This is somewhat similar to the situation brewing with the use of injectable biosimilar pegfilgrastim (once approved and available) and the Neulasta® Onpro® delivery system. The share of use of the long-acting erythrocyte-stimulating agents has been increasing.

On May 15, 2018, Pfizer’s epoetin biosimilar Retacrit was approved by the Food and Drug Administration (FDA), the first biosimilar competitor to Epogen® and Procrit®. Retacrit is not officially available yet.

In other related biosimilar newsPfizer announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended marketing approval for its biosimilar version of trastuzumab.

Apotex and its Apobiologix division has claimed a significant prize—the first pegfilgrastim biosimilar approval in Western markets. None have been approved in the US or EU to date. Health Canada granted marketing authorization to the company on June 1. The new drug will be called Lapelga™.

What Is the Biosimilar Pegfilgrastim Market Opportunity?

We’ve covered the contest to bring a biosimilar pegfilgrastim to market, with considerable depth. The progress and setbacks of Mylan/Biocon, Coherus Biosciences, Sandoz, and Apotex have been tracked. Other drug makers are also working on plans towards 351(k) applications for approval. Eventually—likely sooner than later—one or two will hit the market.

Biosimilar Pegfilgrastim, Neulasta®, and Onpro®

Amgen, maker of the originator product Neulasta®, disclosed in its first-quarter financial report that the total sales for the product in the US is $1.0 billion, $146 million for the rest of the world, for a total of $1.15 billion. This means a US market of approximately $4 billion for one year of sales. Amgen also noted that 62% of its first-quarter Neulasta sales are associated with its Onpro® kit. Although the major patents for pegfilgrastim have expired, Onpro is still protected by patent. Onpro does have some significant advantages in that the patient does not need to go to the doctor’s office for an injection after receiving chemotherapy. The sales figures indicate that doctors prescribe it in preference to the injectable form of pegfilgrastim.

Neulasta OnproAt a current 62% marketshare for Neulasta Onpro, the initial total slice of the pie available for biosimilars may only be $1.5 billion (not considering WAC discounts). If we assume a 20% discount, this may be closer to $1.2 billion. It may not seem logical for Amgen to make great efforts to defend its share of injectable pegfilgrastim because of its successful conversion to Onpro. Also, Onpro does have marketable advantages over the injectable form.

The list price of Neulasta is upwards of $7000 per injection, and Amgen does not charge additionally for the Onpro kit. This stance may prove an incentive to health plans and insurers to not encourage biosimilar use over Onpro.

Will Physicians Resist Moving From Onpro to a Biosimilar Pegfilgrastim Injection?

The $1.2 billion to $1.5 billion estimate also assumes that Amgen cannot convert more patients to Onpro prior to approval of a new biosimilar. That would further shrink the revenue opportunity. Physicians may also resist payer efforts and not prescribe the injectable form if they favor the Onpro kit. To the extent that payers may prefer the biosimilar (or otherwise restrict the use of a more expensive originator agent) when it becomes available, that slice of the pie could increase quite a bit. Furthermore, the picture could also change in a few years as biosimilar manufacturers develop delivery systems that gain the same advantages as Onpro.

In its earnings report, Amgen indicated the sales of Neulasta have been decreasing, by 5% from the same quarter last year. This may be the result of movement to other, less-toxic cancer chemotherapies or other treatments to prevent neutropenia and its related infections.

The Onpro market for the rest of the world may be given a boost soon, as Amgen also announced that the European Medicines Agency issued a positive opinion for the drug maker to include the Onpro Kit in its EU label.

As reported in BR&R, Coherus CEO Denny Lanfear thought the pegfilgrastim market may be split in a manner similar to that for filgrastim (i.e., 30%/30%/40% shares for 2 biosimilar makers and the originator). That may possibly mean 30% of a $1.2 billion US market (not $4 billion), if payers do not emphasize the use of the biosimilar over Onpro.
