01 MAY 2023 | US | Amgen commences BPCIA proceedings against Sandoz, Novartis and Lek re 21 Prolia® and Xgeva® (denosumab) patents in NJ

On 1 May 2023, Amgen instigated proceedings in the US District Court of New Jersey against Sandoz, Novartis and Lek, alleging infringement of 21 patents relating to Amgen’s Prolia® and Xgeva® (denosumab) products.  Sandoz submitted its aBLA to the FDA in December 2022 (which was accepted on 6 February 2023) seeking approval of its anti-RANKL mAb Prolia® and Xgeva® biosimilar.

Amgen is asserting that Sandoz/Novartis/Lek failed to comply with the BPCIA 42 U.S.C. § 262(l)(2)(A) “patent dance” requirements, and is seeking declaratory judgement under § 262(l)(9)(C).

Interestingly, of the 21 patents in suit, there are 2 product patents, and 19 process patents including many to media related “inventions”.

The asserted patents (and the nature of the patent, according to Amgen) are:

  • 7,364,736 (“the ’736 Patent”) – denosumab sequence patent
  • 7,928,205 (“the ’205 Patent”) – process (reduction/oxidation reagent + (optionally) a chaotopric agent)
  • 8,058,418 (“the ’418 Patent”) – product patent;
  • 9,012,178 (“the ’178 Patent”) – methods of culturing mammalian cells to express protein in a serum free media
  • 9,133,493 (“the ’493 Patent”) – methods of culturing mammalian cells (tyrosine and cysteine feeds)
  • 9,228,168 (“the ’168 Patent”) – methods of stabilizing feed media (pyruvate)
  • 9,320,816 (“the ’816 Patent”) – methods of treating cell culture media (UV C light and filtration)
  • 9,328,134 (“the ’134 Patent”) – methods of making proteins with modified glycosylation profile
  • 9,359,435 (“the ’435 Patent”) – methods of modulating glycoform content (mannose)
  • 9,481,901 (“the ’901 Patent”) – methods of influencing high mannose glycoform content (mannose sugars)
  • 10,167,492 (“the ’492 Patent”) – methods of influencing fucosylated glycan content
  • 10,513,723 (“the ’723 Patent”) – methods of influencing high mannose glycoform content
  • 10,583,397 (“the ’397 Patent”) – systems and methods to control filtration
  • 10,822,630 (“the ’630 Patent”) – methods of influencing fucosylated glycan content
  • 10,894,972 (“the ’972 Patent”) – methods of influencing high mannose glycoform content (mannose sugars)
  • 11,077,404 (“the ’404 Patent”) – systems and methods to control filtration
  • 11,098,079 (“the ’079 Patent”) – methods of using a charged depth filter
  • 11,130,980 (“the ’980 Patent”) – methods of regulating high mannose glycoform content (monensin)
  • 11,254,963 (“the ’963 Patent”) – methods of influencing high mannose glycoform content
  • 11,299,760 (“the ’760 Patent”) – methods of regulating high mannose glycoform content (monensin)
  • 11,434,514 (“the ’514 Patent”) – methods of influencing high mannose glycoform content (mannose sugars).

Given the timing of Sandoz’s submission, in the ordinary course of events its approval will precede expiry of US patent no. 7364736 to the denosumab antibody in February 2025.

Prolia® is indicated for the treatment of osteoporosis, and Xgeva® is indicated for the prevention of skeletal-related events in patients with multiple myeloma and bone metastases from solid tumours; and treatment of giant cell tumour of bone.

01 MAY 2023 | US | Government Funded Study suggests US 340B Drug Pricing Program inhibits biosimilar uptake

A study published in Health Affairs has suggested the US 340B Drug Pricing Program has reduced biosimilar uptake in hospitals that participate in the Program.  The 340B Program offers eligible safety-net hospitals (almost one third of US hospitals) to purchase originator medicines at a significant discount.  The authors analysed figures on filgrastim and infliximab and estimated that 340B program eligibility was associated with a 22.9% reduction in biosimilar adoption.

The research was sponsored by the Commonwealth Fund.

01 MAY 2023 | EU | US | FDA accepts BMS’ sBLA and EMA validates variation application for Reblozyl® (luspatercept)

Bristol Myers Squibb announced that the FDA has accepted its sBLA, and the EMA has validated its Type II Variation Application, for Reblozyl® (luspatercept-aamt) to include treatment of anaemia (without previous use of erythropoiesis-stimulating agents in adults with very low- to intermediate-risk myelodysplastic syndromes who may require red blood cell transfusions).  The FDA granted the application Priority Review and assigned a Prescription Drug User Fee Act goal date of 28 August 2023.

In August 2021, the TGA approved Reblozyl® for transfusion dependent anaemia.

27 APRIL 2023 | US | Samsung Bioepis files IPR petition against a Regeneron aflibercept (Eylea®) patent

Samsung Bioepis filed an IPR petition against Regeneron’s US patent no. 11,253,572directed to methods of treating an angiogenic eye disorder by intravitreal injection of aflibercept via a specified dosage regime, with a specified result.

Apotex (unsuccessfully) filed an IPR against claims 1-14 of the Patent on 10 March 2023, as the PTAB denied institution of Apotex’ petition in March 2023.  Conversely, Samsung is challenging all 30 claims of the Patent.   Samsung argues that a number of the claims are anticipated by press releases and a peer reviewed publication pertaining to phase III clinical trials for aflibercept.  It is also arguing that various claims are invalid for obviousness in light of those disclosures.

This comes only two days after Samsung released its new phase III trial data for its aflibercept (Eylea®) biosimilar.

25 APRIL 2023 | US | BMS sues AstraZeneca for infringement of durvalumab and nivolumab patent

BMS has brought proceedings against AstraZeneca in the US District Court of Delaware for infringement of alleging that AstraZeneca’s Imfinzi® (durvalumab) infringes the patent relating to anti-PD-L1 antibodies.  BMS also claims that ‘899 encompasses the BMS product Opdivo® (nivolumab).

The US District Court of Delaware has already set down BMS’ patent infringement case against AstraZeneca regarding Imfinzi® (durvalumab) as a jury trial in April 2024.  It is unclear whether BMS intends to seek to have the two matters heard together.

19 APRIL 2023 | US | Claim construction order issued in Regeneron/Mylan aflibercept case

The US District Court of West Virginia has issued a claim construction order pertaining to seven claims of the four patents asserted in Regeneron’s BPCIA case against Mylan.  The four patents in suit (US Patent Nos. 10,888,60111,084,86511,253,572, and 11,104,715) are directed to Regeneron’s Eylea® (aflibercept).  The Court only adopted one of Regeneron’s proposed constructions of the terms, and adopted the remaining six terms as proposed by Mylan.  On 20 April 2023, Mylan sought summary judgment of non-infringement or invalidity of particular claims in the above four patents.  The case is set down for an expedited two-week trial beginning 12 June 2023.

Regeneron/Sanofi’s Dupixent® (dupilumab) improves EoE

A Regeneron-sponsored study presented at Digestive Disease Week 2023 in Chicago concluded that Regeneron/Sanofi’s Dupixent® (dupilumab) improves histologic, symptomatic, and endoscopic aspects of eosinophilic esophagitis (EoE).  Dupilumab was effective regardless of whether adolescent and adult patients had a history of dilation, and improved outcomes for primary and key secondary efficacy endpoints.

Last week Health Canada issued a Notice of Compliance for Sanofi’s Dupixent® (dupilumab) for the treatment of patients over 12 with EOE.

Study Shows Promise for Dupilumab in Treating Hand and Foot Dermatitis

A study published in the Journal of Allergy and Clinical Immunology: In Practice reports that Dupilumab holds promise for adults and adolescents with moderate to severe atopic hand and foot dermatits.

This comes 6 years after the FDA approved Dupixent® (dupilumab) for atopic dermatitis.

Poor Drafting and Poor Choice of Expert Brings Calix Process Patent To Boiling Point

Calix Limited v Grenof Pty Ltd [2023] FCA 378

Date:
Court:
Judges:

28 April 2023

Federal Court of Australia

Nicholas J

Highlight

Nicholas J considered for the first time, and rejected, the application of section 121A of the Patents Act which reverses the onus for infringement for process patents in certain circumstances.

Background

Australian industrial technology company Calix Limited (Calix), the proprietor of Australian patent no. 2014339743 (the patent), commenced proceedings against government-backed water treatment innovation company Grenof Pty Ltd (Grenof) and DGL subsidiary waste water solutions company Aquadex Pty Ltd in relation to the exploitation of a magnesium hydroxide slurry as “Phodine” and “Phodine Plus” in Australia.  The products are used as a neutralising agent for waste water.

Calix alleged infringement of claim 1 directed to methods of manufacture of a hydroxide slurry.  Such slurries are widely used in industrial processes including in sewerage treatment and precipitating heavy metals.  Grenof filed a cross claim seeking revocation of claim 1 on the grounds that the claim lacked novelty and inventive step, and was not clear or supported by the specification.

In this April 2023 decision regarding a post Raising the Bar (Post-RTB) patent, Nicholas J considered and rejected the application of section 121A of the Patents Act which reverses the onus for infringement for process patents in certain circumstances.  Despite s121A coming into effect in January 1995, it has not been fully considered by a Court.  The structure of s121A is such that the onus reversal will only apply in limited circumstances, and the patentee’s case fell short of the criterion of the section.

Nicholas J found that the claim in suit was not infringed, and whilst it was novel and clear, it was invalid for lack of inventive step and lack of support, his Honour finding in relation to support that “the invention as defined by claim 1 is fundamentally different from the invention disclosed in the body of the specification”. His Honour was underwhelmed by the “confused and muddled” patent specification, and was critical of the expert evidence led by the patentee providing clear examples of practices prosecutors and litigators should avoid.

Given his Honour’s finding of non-infringement and validity, he also found Calix had engaged in unjustified threats (of infringement), although he found Grenof had suffered no damage.

Calix was ordered to pay Grenof’s costs.  It has not filed an appeal.

Key issues

The Claimed Process

The process of claim 1 included mixing caustic calcinated carbonate powder or caustic calcinated hydroxide powder with water, and then the steps of (i) allowing heat of hydration to raise the temperature of the reaction mixture to near the boiling point, and (ii) allowing steam to evaporate from the reaction mixture to remove excess heat and control the maximum reaction temperature to “near the boiling point”.  The claim feature ‘near the boiling point’ was a key issue in both the infringement and validity analysis of the Court.

Rejecting the patentee’s evidence, His Honour ultimately found that ‘near the boiling point’ refers to temperatures near to but not at or above the boiling point of water (i.e. 100°C).  Ominously, Nicholas J described the patent specification as a ‘confused and muddled document, especially when regard is had to the temperature limitation (“near the boiling point”)’.  He was critical of the patentee’s evidence on this feature of the claim, and gave it little weight, finding it “contradictory and inconsistent” and “unconvincing and often inconsistent.  His Honour also commented at one point that the witness “stubbornly refused to accept the obvious implication of his own evidence”.  The Court questioned whether Professor Sorrell would qualify as the person skilled in the art, as he had insufficient practical interest, training or experience to provide evidence on the common general knowledge at the patent priority date.

Calix’s infringement case relied on the submission that the maximum reaction temperature reached during the Grenof process was near, but not at or above, the boiling point of the reaction mixture.  Pursuant to an interlocutory application by Calix, Nicholas J issued orders permitting an independent expert called by Calix to examine the equipment used in the Grenof process and observe its operation.  The experts measured the Grenof reaction mixture temperature as at least 101°C.

First Attempted Onus Reversal Under S121A for Process Patents Fails

Interestingly, in the first case of its kind, Calix sought to rely on s121A of the Patents Act 1990 (Cth) to shift the burden of proof for infringement to Grenof.  s121A provides that in the case of proceedings for infringement of a patent to a process for obtaining a product (only):

  • if the defendant alleges it has used a different process from the one claimed to obtain an identical product; and
  • the Court is satisfied that it is very likely the defendant’s product is made by the patented process, and the patentee has taken reasonable steps to find out the defendant’s process but has not been able to do so;

then in the absence of proof to the contrary (for which the onus is on the defendant) the defendant’s process is taken to have been obtained by the patented process.

Nicholas J discussed s121A:

The section is primarily aimed at circumstances in which the plaintiff has access to the defendant’s product, but not the defendant’s process (eg. because it is used by a third party overseas and is unavailable for inspection by the plaintiff)….

In the context of this dispute His Honour found:

Section 121A can only apply if the Court is satisfied (inter alia) that it is “very likely” that those products were made by the patented process (ie. the method of claim 1).  ….There is nothing about the respondents’ product which satisfies me that it is likely, much less very likely, that it was made by the method of claim 1.  In those circumstances, s121A of the Act cannot apply.”

Nicholas J held that the Grenof reaction mixture “reaches boiling point and boils” and therefore avoids infringement.

Outcome

The claims were found novel.

On obviousness, Nicholas J held that it was well known that the chemical reaction claimed was exothermic, i.e. it produced heat, and that as the powder reagents react with water, at normal pressure the steam resulting from boiling will prevent the reaction mixture from exceeding the boiling point of the excess water. He also held that controlling the mixing rate and the reagent feed rate and rations to keep the reaction mixture close to but below the boiling point would have been routine as at the priority date of the patent.  Moreover, he held this practice was in fact carried out at the priority date to avoid excessive pressure in the reaction mixture.  Given his findings on common general knowledge, he found the claims to be clear but not inventive.

Nicholas J also found the claims lacked support.  Under the post-RTB Act, the claims must be supported by the technical contribution to the art as determined from the description.  As the embodiments in the description included various procedures incorporating boiling, his Honour held that the overall disclosure in the specification was to a process in which the reaction mixture was permitted to reach boiling and therefore could not support a claim in which this was restrained.

Practical Implications for Drafting and Litigation

This decision highlights the importance of fully understanding the invention when the drafting process begins, so that the claims and the disclosure in the specification are aligned.  Where the scope of the claims is arguably narrower than the disclosure, it is not a given that the claims will be adequately supported for the purposes of the Act.  The disparity between the claims and description in this case not only left the patent vulnerable on validity, it also doomed the patentee’s infringement case.  This incongruence may have resulted from an evolution in strategies adopted during patent prosecution stage which should have resulted in a strategic audit of the entire patent family, not just the claims in isolation.

Calix will likely rue its expert selection which drew the criticism of the Court equally for his lack of appropriate technical expertise, for his self-contradiction, and for his stubborn refusal to make reasonable concessions.

It is an open question whether claim amendments, available to a patentee during Court proceedings at the judge’s discretion but not sought here, may have assisted the patentee.

Organon has published its results for Q1 2023, demonstrating biosimilars revenue increased 18% and 20% ex-FX.  The results indicate that this increase was primarily driven by Renflexis® (biosimilar to Janssen’s Remicade® infliximab-abda) which grew 34% ex-FX due to continued demand growth in the United States and Canada as well as Brenzys™ (biosimilar to Amgen’s Enbrel® etanercept) which grew 36% ex-FX as a result of timing of tenders in Brazil.  The report confirms that the ongoing competitive pressures in Europe more than offset strong US growth in Ontruzant®(biosimilar to Genentech’s Herceptin® trastuzumab-dttb).

Organon only launched Ontruzant® and Aybintio® (biosimilar to Genentech’s Avastin® bevacizumab) in Canada in November 2022.

Boan Biotech commences phase III clinical trials for Prolia®/Xgeva® (denosumab) biosimilar

Luye Pharma announced that it has enrolled its first subject in an international multi-center Phase 3 clinical study for its internally developed denosumab products (BA6101 and BA1102) to be carried out in Europe, the United States, and Japan. BA6101 and BA1102 are biosimilars to Amgen’s Prolia® and Xgeva®, respectively.   Prolia® is indicated for the treatment of osteoporosis, and Xgeva® is indicated for the prevention of skeletal-related events in patients with multiple myeloma and bone metastases from solid tumours, and treatment of giant cell tumour of bone.

BA6101 (Boyoubei®) was approved for marketing in China in November 2022, as the first approved Prolia® biosimilar in the world, and China’s NMPA has accepted Boan’s BLA for approval as an Xgeva® biosimilar.

FDA accepts BMS’ sBLA and EMA validates variation application for Reblozyl® (luspatercept)

Bristol Myers Squibb announced that the FDA has accepted its sBLA, and the EMA has validated its Type II Variation Application, for Reblozyl® (luspatercept-aamt) to include treatment of anaemia (without previous use of erythropoiesis-stimulating agents in adults with very low- to intermediate-risk myelodysplastic syndromes who may require red blood cell transfusions).  The FDA granted the application Priority Review and assigned a Prescription Drug User Fee Act goal date of 28 August 2023.

In August 2021, the TGA approved Reblozyl® for transfusion dependent anaemia.

Government Funded Study suggests US 340B Drug Pricing Program inhibits biosimilar uptake

A study published in Health Affairs has suggested the US 340B Drug Pricing Program has reduced biosimilar uptake in hospitals that participate in the Program.  The 340B Program offers eligible safety-net hospitals (almost one third of US hospitals) to purchase originator medicines at a significant discount.  The authors analysed figures on filgrastim and infliximab and estimated that 340B program eligibility was associated with a 22.9% reduction in biosimilar adoption.

The research was sponsored by the Commonwealth Fund.

Amgen commences BPCIA proceedings against Sandoz, Novartis and Lek re 21 Prolia® and Xgeva® (denosumab) patents in NJ

On 1 May 2023, Amgen instigated proceedings in the US District Court of New Jersey against Sandoz, Novartis and Lek, alleging infringement of 21 patents relating to Amgen’s Prolia® and Xgeva® (denosumab) products.  Sandoz submitted its aBLA to the FDA in December 2022 (which was accepted on 6 February 2023) seeking approval of its anti-RANKL mAb Prolia® and Xgeva® biosimilar.

Amgen is asserting that Sandoz/Novartis/Lek failed to comply with the BPCIA 42 U.S.C. § 262(l)(2)(A) “patent dance” requirements, and is seeking declaratory judgement under § 262(l)(9)(C).

Interestingly, of the 21 patents in suit, there are 2 product patents, and 19 process patents including many to media related “inventions”.

The asserted patents (and the nature of the patent, according to Amgen) are:

  • 7,364,736 (“the ’736 Patent”) – denosumab sequence patent
  • 7,928,205 (“the ’205 Patent”) – process (reduction/oxidation reagent + (optionally) a chaotopric agent)
  • 8,058,418 (“the ’418 Patent”) – product patent;
  • 9,012,178 (“the ’178 Patent”) – methods of culturing mammalian cells to express protein in a serum free media
  • 9,133,493 (“the ’493 Patent”) – methods of culturing mammalian cells (tyrosine and cysteine feeds)
  • 9,228,168 (“the ’168 Patent”) – methods of stabilizing feed media (pyruvate)
  • 9,320,816 (“the ’816 Patent”) – methods of treating cell culture media (UV C light and filtration)
  • 9,328,134 (“the ’134 Patent”) – methods of making proteins with modified glycosylation profile
  • 9,359,435 (“the ’435 Patent”) – methods of modulating glycoform content (mannose)
  • 9,481,901 (“the ’901 Patent”) – methods of influencing high mannose glycoform content (mannose sugars)
  • 10,167,492 (“the ’492 Patent”) – methods of influencing fucosylated glycan content
  • 10,513,723 (“the ’723 Patent”) – methods of influencing high mannose glycoform content
  • 10,583,397 (“the ’397 Patent”) – systems and methods to control filtration
  • 10,822,630 (“the ’630 Patent”) – methods of influencing fucosylated glycan content
  • 10,894,972 (“the ’972 Patent”) – methods of influencing high mannose glycoform content (mannose sugars)
  • 11,077,404 (“the ’404 Patent”) – systems and methods to control filtration
  • 11,098,079 (“the ’079 Patent”) – methods of using a charged depth filter
  • 11,130,980 (“the ’980 Patent”) – methods of regulating high mannose glycoform content (monensin)
  • 11,254,963 (“the ’963 Patent”) – methods of influencing high mannose glycoform content
  • 11,299,760 (“the ’760 Patent”) – methods of regulating high mannose glycoform content (monensin)
  • 11,434,514 (“the ’514 Patent”) – methods of influencing high mannose glycoform content (mannose sugars).

Given the timing of Sandoz’s submission, in the ordinary course of events its approval will precede expiry of US patent no. 7364736 to the denosumab antibody in February 2025.

Prolia® is indicated for the treatment of osteoporosis, and Xgeva® is indicated for the prevention of skeletal-related events in patients with multiple myeloma and bone metastases from solid tumours; and treatment of giant cell tumour of bone.

28 April 2023 | US | FDA advisory committee supports approval of Merck’s Lynparza® (olaparib) combination for first line treatment of prostate cancer

Merck announced that the FDA’s Oncologic Drugs Advisory Committee (ODAC) has voted to support FDA approval of Lynparza® (olaparib) plus abiraterone and prednisone or prednisolone for the first-line treatment of BRCA-mutated metastatic castration-resistant prostate cancer (mCRPC).  ODAC voted against approval for the combination beyond this patient population.

Lynparza® is currently approved in the US for patients with homologous recombination repair gene-mutated mCRPC who have progressed following prior treatment with enzalutamide or abiraterone.  It is also approved for the treatment of ovarian, breast and pancreatic cancer.  The first line combination use is approved in Europe for mCRPC patients in whom chemotherapy is not clinically indicated.

26 April 2023 | EU | New EU pharmaceutical reforms will impact biosimilars

The European Commission (EC) has adopted a proposal for a new Directive and a new Regulation which will revise and replace the existing pharmaceutical legislation, and amount to the largest regulatory reform in the EU in over 20 years.  The Directive and Regulation have been submitted to the European Parliament and the Council of the EU for discussion.  The EC confirmed that discussions will start as soon as possible, however it cannot predict the timing for adoption.  Both the Parliament and Council will need to approve the reforms.

The regulatory reforms aim at increasing patient access to affordable medicines and improving the security of supply.  EC Vice-President Margaritis Schinas has described the changes as “enormous”.

Key measures include:

  • A 2 year reduction of the baseline data protection period in order to encourage early market access of generics and biosimilars. However, additional periods of data protection may be available when certain conditions, potentially extending the period of regulatory protection beyond those currently available.
    • Companies marketing innovative medicines will have a minimum period of regulatory protection of 8 years, which includes 6 years of data protection and 2 years of market protection. However companies may benefit from additional periods of protection (total period up to 12 years, compared 11 years today).  These additional periods of protection can be obtained if the medicine is launched in all Member States (+2 years), if the medicine addresses an unmet medical need (+6 months), or if comparative clinical trials are conducted (+6 months).  A further year of data protection can be granted if the medicine can treat other disease(s) too.  The 2 year protection based on launch in all Member States is expected to increase access by 15%.
    • For rare disease medicines the standard market exclusivity will be set at 9 years. Companies may benefit from additional periods of market exclusivity if they launch in all Member States (+ 1 year), address a high unmet medical need (+1 year), or develop new therapeutic indications for an already authorised orphan medicine (up to 2 extra years). The total regulatory production periods can add to 13 years (today the maximum is 10 years).
  • Broader scope of the ‘Bolar exemption’: biosimilars will not need risk management plans as the originator will already have one.
  • An incentive for repurposing
  • Faster authorisation of new medicines:
    • The EMA will have 180 days instead of 210 to assess new medicines
    • If medicines are of major public health interest, the EMA will only take 150 days
    • The EC will have 46 days instead of 67 for authorisation
  • Regulatory ‘sandboxes’ to test new regulatory approaches for novel therapies under real world conditions.
  • The ability for governments to suspend data and market protection when a compulsory licence has been issued to tackle a public health emergency.

26 April 2023 | EU | CHMP recommends approval of Roche’s Columvi® (glofitamab) for R/R DLBCL

Roche announced that the EU’s European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended the approval of Columvi® (glofitamab) for the treatment of adults with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) as a third line therapy.  The recommendation was based on results from a phase I/II study, in which Columvi® was demonstrated to induce early and long-lasting responses in people with R/R DLBCL.

This news comes less than two weeks since the FDA approved Genentech/Roche’s Polivy® (polatuzumab vedotin-piiq) in combination with Rituxan® (rituximab) for DLBCL.

26 April 2023 | EU | CHMP recommends approval of Novartis’ Cosentyx® (secukinumab) for moderate to severe hidradenitis suppurativa

Novartis announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended the grant of marketing authorization for Cosentyx® (secukinumab) in adults with active moderate to severe hidradenitis suppurativa, an inflammatory skin disease.  The recommendation was based on results from two phase III trials which showed that patients who received Cosentyx® continued to improve beyond the primary endpoint analysis at week 16, with more than 55% of patients achieving a Hidradenitis Suppurativa Clinical Response at week 52.

Last year BioThera began phase III trials of BAT2306, biosimilar to Cosentyx®,  in patients with moderate to severe plaque psoriasis.
