What is a TPP?• Key strategic planning document that:
– Provides a clear understanding of requirements and expectations of the ultimate outcome of product development
– Is driven by unmet patient, physician and payer needs at time of launch
• Roadmap of key Go/No-Go decision points • Statement of the overall intent of the product
development program– and much more than just a draft product label
![Page 5: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/5.jpg)
What is a TPP?
A differentiated value proposition Snapshot in time
Summary of studies that justify labeling claims
Dynamic & multidisciplinary document
Communication tool Starting point for annotated package insert (label)
![Page 6: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/6.jpg)
Link to FDA Guidance
The purpose of a TPP is to provide a format for discussions that can be used throughout the drug development process. The TPP embodies the notion of beginning with the goal in mind.
The TPP provides a statement of the overall intent of the drug development program, and gives information about the drug at a particular time in development.
The TPP is a dynamic summary that changes as knowledge of the drug increases.

Road Map for Development
• Focuses development • Required studies – no more, no less –
become apparent• Requires comparison with similar
products• Constant updating of indication
required– With new information from your studies
& market– Go/No-Go decision points are forced
![Page 8: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/8.jpg)
When is the TPP Needed?
• As early in development as possible– Pre-IND Meeting – IND– End-of-Phase 1 Meeting– End-of-Phase 2 Meeting – Annotated Package Insert Template– Pre-NDA or -BLA Meeting
![Page 9: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/9.jpg)
Establish the Targets Early
• Begin with the end in mind– “If you don’t know where you’re going,
you’ll be lost when you get there.” Yogi Berra• Interdisciplinary activity
– Project teams (Clinical/Nonclinical/CMC/Regulatory)
– Labeling and marketing teams• Initial interdisciplinary and senior
management input and buy-in• Decision log
– Conflict resolution system– Go/No-Go rationale
![Page 10: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/10.jpg)
Typical TPP Checklist Includes:• Scientific rationale• Preclinical support• Toxicology/ADME/PK• Acute vs. chronic indication• Unmet need• Clear diagnostic criteria• Target population or
subpopulation• Clinical plan• Anticipated safety profile, drug
interactions• Contraindications
• Regulatory plan• Endpoints (with estimate of
needed benefit)• Manufacturing/stability issues• Route of administration• Anticipated storage conditions• Desired shelf life• FDA guidelines available• International objectives• Competition• Patents

Common Pitfalls• Interdisciplinary input not sought• Late stakeholder buy-in• “Interest group”-driven targets • Lack regulatory intelligence• No prospective key decision points• Failure to revisit when new data obtained• Failure to use it as a tool for planning, development,
communication
![Page 18: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/18.jpg)
Example Starting Point: Novel antidepressant
• Currently marketed AD’s are only effective in about 50% of patients because of problems with tolerability and/or lack of efficacy
• Currently marketed AD’s have relatively few significant drug interactions
• Currently marked AD’s are generally given once-daily
• Currently marketed AD’s, when they do work, may require a few weeks for significant effect
• The world doesn’t need another expensive variation of a currently marketed antidepressant
What’s known
![Page 19: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/19.jpg)
Example: Novel antidepressant
• A once-daily antidepressant, with no significant drug interactions, and one or more of the following:• Rapid onset (placebo separation by the
end of the first week)• Good tolerability, including no sexual
dysfunction, weight gain, or sedation• Robust efficacy greater than that of
currently marketed AD’s (and not less than)

Clinical Development Plan• Phase 3
– Focus on efficacy and safety– Pivotal or confirmatory if adequate, well-controlled and agreed
with FDA– Target population & regimen for market– Generally at least 2 studies required– Major basis for marketing approval decisions and label
• Phase 2– Focus on efficacy and safety, proof-of-concept– Population - patients with target disease– Dose range finding, dose selection for phase 3– Further define outcomes/endpoints, population
• Phase 1– Focus on safety, pharmacokinetics, pharmacodynamics– First in human, SAD, MAD– Drug interactions, Thorough QT, food effect, bioavailability
![Page 35: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/35.jpg)
Nonclinical Development Plan• Comprehensive assessment of the pharmacology,
pharmacokinetics, and toxicity of the drug substance and product
• How are data used?– Dose selection for initial clinical trials– Pharmacodynamics, MOA, biomarker development– Therapeutic index– Specific safety monitoring, use in specific populations– Labeling
• GLP requirement for some studies• Dose selection is critical for safety studies
![Page 36: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/36.jpg)
Chemistry, Manufacturing, & Controls (CMC) Plan• Assure proper identification, quality, purity and
strength• Manufacture active pharmaceutical ingredient
(API)• Analytical assay development & validation• Pre-formulation/formulation development• Manufacture of Clinical trial material
– Release testing– Packaging and labeling– Comparators (active or placebo)
• Stability
![Page 37: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/37.jpg)
Regulatory Strategy• Filing Pathway
– 505(b)(1), 505(b)(2), 505(j), drug-device combination
– What data are required for each pathway– Pertinent regulatory hurdles
• Understand competition– Review labels, SBAs, EPARs, financial reports
• Awareness of region specific regulations– ICH– FDA– EMA
![Page 38: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/38.jpg)
Regulatory Strategy
• Orphan Drug Designation• Qualify for acceleration mechanisms?
– Breakthrough Therapy– Accelerated Approval – Priority Review
Know your drug to take advantage of these programs!
![Page 39: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/39.jpg)
Type B Development Meetings with FDA
• Pre-IND Meeting
• End of Phase 1 Meeting
• End of Phase 2 Meeting
• Pre-NDA Meeting

Initial Agency Interactions• Pre-IND
– Obtain Agency buy-in on: • Clinical protocol• Nonclinical safety studies• CMC program
• What is required:– IPDP in Briefing Document– Well-written questions
• No open-ended questionsWhen is the right time to schedule meeting???
![Page 41: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/41.jpg)
Avoiding Delays (e.g., Clinical Hold)• Unfocused development plans are
doomed to lead to delays• CDER receives approx. 1500 IND
submissions per year• Lapteva and Pariser (Journal of Investigative Medicine,
2016)
– In 2013, 9.0% were placed on clinical hold
– Most commonly cited reasons• CMC• Clinical • Toxicology
![Page 42: Get Your Development Program Started on the Right Foot](https://reader036.fdocuments.us/reader036/viewer/2022081604/58cf4b0c1a28aba17e8b4a15/html5/thumbnails/42.jpg)
Common Reasons for Clinical Hold• Poorly organized submission and/or insufficient information• Inadequate information to assess safety• Clinical study design too aggressive, lacks needed safety
monitoring, dose limiting toxicity is not well defined and/or stopping rules inadequate, inadequate inclusion/exclusion criteria
• Unqualified impurities, excipients in clinical batch or poorly defined impurity profile
• Drug product not stable throughout the testing program• NOAEL not determined in toxicity study(ies)
