DISCLOSURE APPENDIX AT THE BACK OF THIS REPORT CONTAINS IMPORTANT DISCLOSURES, ANALYST CERTIFICATIONS, LEGAL ENTITY DISCLOSURE AND
THE STATUS OF NON-US ANALYSTS. US Disclosure: Credit Suisse does and seeks to do business with companies covered in its research reports. As a result, investors should be
aware that the Firm may have a conflict of interest that could affect the objectivity of this report. Investors should consider this report as only a single factor in making their investment
decision.
Updating Investors on Progress of Biosimilars: We are publishing the latest version of
our Biosimilars Tracker, where we provide a more comprehensive look at the latest
developments in the biosimilar market, including updates on how the regulatory, legal and
payer landscape may be evolving to help create a more vibrant biosimilar market, including
in the US.
Impact of Biosimilar Humira Most Closely Watched in the EU: As the world’s best-
selling product, there has been close scrutiny on the erosion of Humira since the entry of
biosimilar versions of the drug in the EU in October. We will get more insights on this
dynamic on ABBV’s 1Q19 earnings call on Apr 25, but they have already acknowledged
they expect a ~30% decline in total ex-US Humira sales in 2019. We look to see if the
company further adjusts its 2019 expectations on the call and, perhaps more importantly,
if they provide greater color on the rate of erosion they expect in 2020 and beyond.
Multiple Pushes and Pulls as Biosimilar Market Evolves: In recent months, we have
seen several additional biosimilar approvals, including another biosimilar Humira in the EU
and multiple biosimilar versions of Roche’s Herceptin. The FDA has also released a series
of guidances and revised guidances to help provide more clarity to biosimilar developers on
what the agency is looking for to approve biosimilar and potentially interchangeable
products. However, we have also seen continued commercial challenges with the rollout of
some biosimilars in the US market, most notably biosimilar versions of Remicade which
have only obtained about 8% of infliximab molecule share despite multiple biosimilar
versions of Remicade being on the US market for nearly two years now.
Pfizer, Novartis Best Positioned, While AbbVie, Roche Most at Risk: Pfizer and
Novartis face potential sales erosion from biosimilars in the coming years, but they are also
developing their own biosimilars that we expect to help offset some of that risk. On the
other side of the spectrum, we see AbbVie and Roche as the two companies most
exposed to biosimilar risk given the threat to their blockbusters Humira (for AbbVie) and
Rituxan, Herceptin and Avastin (for Roche).

Numerous Recent Regulatory and Commercial Developments in the
World of Biosimilars
Regulatory Developments
− US approval of Trazimera, Herzuma and Ontruzant (biosimilars of Herceptin) from Pfizer, Teva/Celltrion and
Samsung Bioepis, respectively
− EU approval of Ogivri (biosimilar Herceptin) from Mylan and Idacio (biosimilar Humira) from Fresenius
− Celltrion’s EU application for self-administered SC formulation of Remsima has been accepted in Dec 2018
and a decision is expected in 2H2019. They will launch a Phase 3 study of the product this year and plans
to launch the product in the US by 2022
− Progress on Biosimilar Action Plan – FDA issued four new guidances in Dec 2018 to provide more clarity on
scientific and regulatory considerations for the development of biosimilars and interchangeable products and
how the agency plans to implement the transition of certain products from the drug to biological pathway
− FDA released revised guidance on ‘Nonproprietary Naming of Biological Products’ where the retrospective
requirement for renaming already licensed biologics with four letter suffix has been removed
Commercial Developments
− In the US, the impact of biosimilar versions of Remicade continues to be far less than expected, with JNJ’s
brand still holding onto 92% of infliximab molecule share in 1Q19. On the other hand, Coherus pre-
announced better-than-expected net sales for Udenyca (biosimilar Neulasta) of $36-38MM in 1Q19
− In the EU, ABBV has seen greater than expected erosion of Humira to biosimilars in the US, with the
company now guiding to 30% erosion in international Humira sales in 2019, which will likely moderate in
2020 and beyond

Progress on Legal Front Remains Critical for Biosimilar Advancement,
With Some Recent Developments and More Expected Soon
Legal Developments
− In Walgreens/Kroger vs JNJ Remicade antitrust litigation, the district court in March ordered that judgement
be entered in favor of JNJ on all counts granting the argument that the plaintiff lacks antitrust standing. We
continue to believe that the PFE vs JNJ case related to Remicade will set the precedent for such cases in
future
− In Novartis vs Amgen Enbrel BPCIA case, post-trial briefing on the case was completed in December and a
decision from the court is awaited anytime now
− Pfizer and Coherus settled with AbbVie, allowing their Humira biosimilars to be launched in the US in 2023
− Six class action lawsuits were filed by unions and municipalities alleging violation by ABBV of antitrust and
consumer protection laws by extending Humira’s exclusivity with overlapping and non-inventive patents and
we expect more such suits to follow
− In a first biosimilar vs biosimilar case, Coherus sued Amgen in the US, alleging that Amgen’s Humira
biosimilar infringes on its three patents regarding formulations of adalimumab and seeks to stop
manufacturing the product in the US for sale in Europe without a license

Note: Throughout the analyses in this note, complex small molecule drugs (ex: Copaxone, Invega Sustenna) are classified under the biological category
An estimated ~$113Bn of $299Bn (based on 2022 sales) in annual global biological sales is expected to
no longer have patent protection by 2023, leaving door wide open for biosimilar competition
