Iterative Drug Discovery Cycle for LeadGeneration & Lead Optimization
Lead GenerationGoal of ‘Hit-to-Lead’ ProcessIdentify a Lead Chemical Series that meets target product profile:• Demonstrate a reproducible concentration-response curve in primary assays (biochemical & cellular)• Works via desired mechanism of action• Selectivity over closely related counter targets• Devoid of undesirable structural features• Possess drug-like properties• Biological activity is responsive to structural changes at multiple sites in the molecule• Tractable SAR for drug target(s) and drug properties• Strong potential for development of new intellectual property space• Demonstrates acceptable pharmacokinetics and efficacy in animal model

Lead OptimizationGoal: Identify Preclinical Development candidate with desirable Target Profile• In vitro potency & selectivity toward primary drug target(s)• Minimal off-target activity• Acceptable physicochemical properties• Acceptable drug properties• Drug metabolism & pharmacokinetic profile suitable for route of administration• Acceptable safety margin, no genetic toxicity, acceptable hERG and CYP Inh.• Efficacy in animal models• Target Engagement, biomarker or surrogate marker for efficacy• Acceptable margin of safety at efficacious dose• Patentable• Robust chemistry to deliver large quantity of compound for preclinical studies• Identify final form of drug substance
Moving from in vitro to in vivo………. What are you trying to achieve?1. Does the in vitro data translate into in vivo actions?2. Are the in vivo models predictive of the disease?3. Are the models confirming an action at the target site?4. Are the in vivo effects due to ‘target engagement’?5. Can we demonstrate good PK/PD relationship?6. Translatability to studies in man.
Outsourcing in vivo studies• Many providers offer in vivo efficacy testing. How do you select the right one? • What is the question you are trying to answer? • Can the provider do both efficacy and PK? • Minimize number of providers • Every time a new provider is involved, new variables are introduced. • Vehicles, formulation preparation etc.• When it comes to in vivo efficacy testing, specialist niche providers have a key role.• Efficacy testing requires therapeutic area expertise • You don’t want your xenograft measured by a behavioral pharmacologist! • And you don’t want your behavioral experiment run by an oncology expert!• Toxicology / Safety testing • Large GLP accredited Tox / Safety CROs. • Cost effective outsourcing. • Have they the experience of running regulatory studies. • Who carries out the pathology, reads the slides? • Do they have the board certified pathologists?

$$ Cost of Outsourcing $$• Cost a significant barrier to direct use of CRO services• Academic drug discovery centers• Non-profits, Foundations and Government Agencies, like the NINDS are making translation of academic innovation into drug therapies possible by providing the financial means for the universities, the NINDS and CROs to work together.

Advancing Preclinical Therapy Development for Alzheimer’s Disease: Funding Opportunities and Services at the NIA 6th ADDF Drug Discovery for Neurodegeneration Conference Feb 12-14, 2012 Suzana Petanceska PhD Division of Neuroscience National Institute on Aging
Alzheimer’s Disease: a Public Health Crisis Currently ~5 million people are affected in the US alone; this numberis projected to triple by 2050. An additional 5.4 million are estimated to be suffering from MCI. Approximately 10% of these will progress to AD each year. The therapeutic needs of patients with Alzheimer’s Disease remain unmet.
NIA’s AD Translational Research Program (2005-present)Goal: To seed early drug discovery and preclinical drug development projects inacademia and in the small business community and in doing so increase thenumber of drug candidates against a variety of therapeutic targets that can beclinically developed by industry or through various clinical trial programs at theNIH.
Target Discovery Basic Research Alzheimer’s Disease Translational Research Program (2005 – present) -from Target Identification to Clinical Trials- SBIR/STTR Clinical DevelopmentIND-enabling Toxicology AD Pilot Clinical Trials, PAR -11-100 (R01) Successful TherapeuticNIA Contract IND AD Cooperative Study (U01) Intervention for AD Investigator Initiated Clinical Trials (R01) Industry
Portfolio Summary The availability of set-aside funds together with specialized review enabled the relatively rapid creation (FY 2006-present) of a diverse portfolio of preclinical AD therapeutics for a variety of therapeutic targets. -~50 early drug discovery projects -15 preclinical drug development projects -13 supplemental awards to existing NIA grants Amyloid beta Tau neurogenesis cdk5 HSP90 neuroinflammation neurotransmitter receptors phosphodiesterases ApoE hormonal signaling neurotrophin receptor signaling

Current NIA Funding Opportunities and Services for AD Drug Discovery and Preclinical Drug Development cntd. R21s and R01s are reviewed at the Center for Scientific Review by the Drug Discovery for the Nervous System review panel. -Scientific Review Officer: Mary Custer, PhD U01 applications are reviewed at NIA’s scientific review branch by the Drug Development review panel. -Scientific Review Officer: Alexander Parsadanian, PhD Requests for access to IND-Enabling Services are reviewed by NIA program staff and two NIA external advisors.
Alzheimer’s Disease Preclinical Drug Development: PAR 12-015 (U01) Milestone Driven Program Supports the pre-clinical development of drugs, biologics, as well as repurposing of drugs already in use for other conditions. For entry into the program, projects must have one or more identified therapeutic leads and convincing proof-of-principle of efficacy in animal model(s) relevant to AD, MCI or age related cognitive decline against a defined therapeutic target. Activities supported: chemical optimization, pre-clinical efficacy testing, predictive ADMET (absorption, distribution, metabolism, excretion, and toxicology) testing, good manufacturing practices (GMP) synthesis and formulation, pre-IND meeting with the FDA, IND-enabling toxicology/safety pharmacology and IND submission. Does not support hypothesis driven mechanistic research, or early-stage drug discovery activities such as high throughput screening. The research plan must include annual quantitative milestones with specific criteria for go/no-go decision making. The milestones are subject of a special review criterion and they are used by NIA program staff to assess progress on the project and to recommend further funding.

How to Apply for Contract Services: Contact the project officer:-Neil Buckholtz PhD email@example.com Provide the project officer with supporting material/data justifying the request for the contract services.
What Follows? The project officer sends the material for review to two external expert advisors. If the request is approved the project officer will put the investigator in touch with the principal investigator (PI) at SRI International: -Karen Steinmetz, PhD, DABT firstname.lastname@example.org The PI at SRI prepares a protocol based on the information provided by the academic/biotech investigator. Once the protocol is approved by the NIH contracting office, SRI will carry out the agreed upon studies. Time between submission of request and approval of protocol for IND- enabling services: 4-6 months.
How to Decide Which Funding Opportunity is Best for Your Project? Send a brief summary (one page) of your prospective project outlining the aims anddeliverables to the appropriate program officer(s).-Suzana Petanceska PhD, email@example.com Program staff will set up a teleconference and discuss the best funding venue(s) at the NIAor refer you to another Institute (NINDS), a trans-NIH funding opportunity, or a non-federalfunding agency (i.e. ADDF). If the project is mature enough to enter the U01 program, program staff willrequest preliminary milestones and budget and will work with the investigator toformulate the quantitative milestones for the application.-Lorenzo Refolo, firstname.lastname@example.org If the project is at late preclinical development stage and needs only IND-safetypharmacology and toxicology, program staff will advise you to submit a request for accessto these services.-Neil Buckholtz PhD, email@example.com
