The Forgotten Keys to Bio-Pharma Transactions – Regulatory, Clinical & Quality Challenges in Due Diligence and Contracting CHI Bridging the Business Development/Alliance Management Interface November 2008 Boston
3 Standard Disclaimers Views expressed here are solely my own and do not necessarily reflect those of my firm or any of our clients. These slides support an oral briefing and may not be relied upon solely on their own to support any conclusion of law or fact.
Todays Focus Through the Regulatory, Preclinical, Clinical & Quality lenses, we will examine these keys to successful alliances: Due Diligence – what you need to do to make sure you dont have to rely on … Contract Clauses – language you need to back up your due diligence A Couple Tales of Deals Gone Awry Deal Drivers – drying pipelines lead to partnering in one form or another – from joint ventures to outright buys
DUE DILIGENCE – What to Look At to Minimize FDA Regulatory, PreClinical, Clinical, and Quality Challenges
Basics Impacting Product Selection Regulatory environment Specific issues regarding guidance or other precedence Regulatory history Understanding how similar products were handled by regulatory bodies FDA Europe – may be different (e.g., medical device regulatory hurdles generally lower)
Diligence: Whats Due Varies by Deal Many types, many sizes Depth of diligence dependent on complexity of the deal and stage of development – Key – your due diligence team must understand what should have been done at the stage of development to which the product/company corresponds Types of Alliances Co-promotion of a product Acquisition of a license Acquisition of all product rights Joint Venture Merger Acquisition of a business unit Complete company acquisition
Due Diligence Structure Focus on areas of greatest criticality – each due diligence will be unique – vary per stage of development Who will be involved -- will vary per product, but is essential to obtain qualified personnel Regulatory U.S. FDA expertise E.U. and other foreign agencies, as applicable Fallacy #1 – if its good enough for FDA, the rest of the world will accept it Preclinical Clinical Quality Internal vs. External – skin in game vs. less bias
Key FDA Diligence Issues Early Stage – still in the lab Is product subject to a written regulatory strategy plan vetted by an outside expert? Is the current strategy sound or will changes be required? What types of proof of concept/principle studies have been done? Are they validated animal models? Product approved abroad? If so, what learned from that? Preclinical Stage How were the tox studies designed? Are they appropriate for the intended population and dosing (e.g., chronic vs. acute) Facility – reputable and GLP compliant? Studies – monitored?
Key FDA Diligence Issues … IND Stage – gone from bench to bedside? Pre-IND meeting held? Results View briefing packages, minutes, FDA correspondence Actual filing Review Clinical hold – verify File being maintained properly? Compare protocols sent to investigators to those sent FDA Did firm have and conduct robust program for handling AEs?
Key FDA Diligence Issues … Pivotal Studies Stage Was there an End of Phase 2 meeting? What was agreed? Was it followed? Statistical power of studies -- sufficient Study design Pressure vs. non-inferiority studies Appropriate arms and controls used?
Key FDA Diligence Issues … Pivotal Studies Stage, cond Did the CRO monitor studies correctly? GCP compliance IRB involvement correct Use of foreign data – acceptable, but … GMP compliance – appropriate to the clinical phase? Scale-up validated Formulation changes documented and validated – FDA wont approve product if commercial scale does not relate to clinical study supply Contract labs – did they meet GLP? Example: MDS Montreal
Key FDA Diligence Issues … NDA/BLA Stage Pre-filing meeting held? Electronically filed Who handled – company or contractor -- e.g., Neurocrine – severe problems in filing; had to be redone Advisory Committee needed – all NCEs now must go to A.C. Risk Management Does the product require a R.E.M.S.? Might it require a post-approval study If so, how big? Has the firm tracked AEs appropriately? Financial bias – adequately addressed; rare, but is a powerful public issue today
Key FDA Diligence Issues FDA Enforced Competitive Restrictions – aka Exclusivity Orphan – 7 years Waxman-Hatch 5-year -- NCE 3-year 180-day – ANDA Marketed Products Changes handled via NDA/BLA supplements Quality – GMP – audits are the answer Example – Ranbaxy Import Alert AE Monitoring – what did they know and when did they know it? Example -- Vioxx
Unique FDA Diligence Challenges Criminal investigations Fraud Application Integrity Policy Debarment – using debarred persons Changing regulatory/legal milieu – e.g., BioSimilars – very difficult to predict right now
Examples of FDA Issues Impacting Deals Alza/Abbott – the buyers (Abbott) regulatory issues, revealed after deal announced, cut share price, sinking deal based substantially on stock exchange Guidant – while not explicitly stated, AE issues kept J&J bid down, allowing Boston Scientific to get firm (but, was it worth it remains to be seen) Gliatech/Guilford – Guilford pulled out when FDA legal issues revealed
THE CONTRACT Key Clauses – Beyond Reps & Warranties -- to Manage the Regulatory, Preclinical, Clinical & Quality Challenges
Contract Clauses … Buyers right to audit seller or contract partner (and sellers key suppliers) without notice at any reasonable time during operations vendor to cooperate fully with audit access to records and personnel to be spelled out Why audit? Right is a check on partner sliding toward non-compliance Good sense – and required by FDA regs (at least on devices)
Contract Clauses … Advance notice of changes in sellers processing – so … Buyer can assess what regulatory action it must take to keep its approval/submission current Buyer can assess if change might change nature of product e.g., carbamazepine – change in synthesis led to different crystalline structure – met spec, but flunked dissolution – API maker did not tell company – massive recall
Contract Clauses … Seller to cooperate, at no [or $___] additional expense, with Buyers needs to take action to continue to comply with FDA requirements (e.g., vendor to provide data to support filing of supplements to make changes to approved applications)
Contract Clauses … Partners relations with FDA... Provide copies of 483s, EIRs Prompt notice to buyer of initiation of FDA inspections Prompt transmission/notice to buyer of any FDA regulatory correspondence or other regulatory action Right of partner to have a representative at other partner during an FDA inspection
Contract Clauses … Timely notice of other problems encountered by partner in its manufacturing process Example: problems in making similar products for others – duty to notify you Timely notice of any adverse reactions or complaints reported to vendor Caveat: define timely Case study – Lilly/Icos Jt. Venture on Cialis – approval delayed about a year due to quality problems at Lilly plant
Contract Clauses … Recalls -- duty of responsible partner to cooperate with recalls initiated by other partner (if applicable) IDE/IND Related – if delegate to a CRO, must specify in contract what duties are delegated Problem – really doesnt insulate sponsor from liability on the business side
Contract Clauses … Active Pharmaceutical Ingredient (API) Sourcing DMF Maintenance – Notice of updates Duty to file at FDA Specify GMP level compliance (U.S. v. EU v. WHO v. ??) IP Compliance – that they are not violating any process patents How DMF file will be updated and who bears the burden of cost to ensure done correctly
Contract Clauses … Pre-approval inspections Notice to Buyer when scheduled Handling Ownership of formulation Allocation of NDA related duties Preparing batch records Preparing labeling IND Formulations – type of equipment and extent of GMP controls applied (varies by phase) Ensuring scale-up and validation done properly
Specific Problems … Two unique ones…. Back-up Manufacturing Plant When needed: whenever manufacturing is contracted out for IND or approved Example: Lilly – 7/18/02 public announcement on 2 nd Quarter results and plant problems not being cured until 2003 What clause says: lets non-mfg. party seek a backup contractor under appropriate circumstances (e.g., Lilly had GMP problems holding up NDA approvals)
Specific Problems … Two unique ones…. Who Owns the Data? When needed: whenever studies of any sort are farmed out Example: Client has major study done at University; contract is ambiguous on who controls the data, although clear client can use in FDA product approval filing What clause says: makes clear who owns both raw data and results and the right to authorize publications and references
