Vitalis Therapeutics Inc. — The work breakdown structure for the VitaFlow (VTX-401) program: eleven Level 2 control accounts mapping one-to-one to the budget cost pools, Level 3 decomposition of the two largest, the 109-person resource model across ten functions, and what is deliberately excluded.
1. What a WBS Is For
A work breakdown structure decomposes the total scope of a program into deliverables, and then into work packages small enough that one person can own one and be held to it.
| Rule | Statement | Why it matters |
|---|---|---|
| The 100% rule | The WBS captures 100% of the scope and nothing outside it | If work is not in the WBS it is not in the program. This is the test that makes a WBS useful rather than decorative. |
| Deliverable-oriented | Nodes are things, not activities | “Registration batches” not “manufacture batches”. Activities belong in the schedule; the WBS defines what is produced. |
| Mutually exclusive | No scope appears in two places | Overlap makes cost roll-up meaningless and creates two owners for one deliverable. |
| Decomposed to a manageable package | Assignable, estimable, trackable | Decomposition stops where a single owner can be held accountable for a discrete result. |
| Control accounts at Level 2 | Where scope, schedule and cost intersect | Each Level 2 node has one accountable owner and one budget. |
The structure captures all of the scope and only the scope. If work is not in the WBS, it is not in the program — and a program manager who finds work being done that has no WBS node has found either uncontrolled scope or an incomplete structure. Both are worth knowing about.
The second rule is the one people break most often. A WBS node is a deliverable, not an activity. “Registration batches” is a node; “manufacture the registration batches” is a schedule activity. Mixing the two produces a structure that is neither a scope definition nor a plan.
2. Level 2 — Control Accounts
| WBS | Deliverable | Control account owner | Scope | Budget | % of base |
|---|---|---|---|---|---|
| 1.1 | Nonclinical Package | Dr. M. Sørensen Nonclinical Safety & Pharmacology | Pharmacology, PK/ADME, safety pharmacology, GLP toxicology, genotoxicity | $8,500,000 | 3.9% |
| 1.2 | Chemistry, Manufacturing and Controls (CMC) — Early Development | Dr. K. Oyelaran Technical Operations / CMC | Route selection, formulation, analytical method development, clinical supply | $6,200,000 | 2.9% |
| 1.3 | Investigational New Drug application (IND) Package | G. Petrossian Regulatory Affairs | Investigator's Brochure, Module 3/4 authoring, Form 1571, submission | $3,800,000 | 1.8% |
| 1.4 | Phase 1 Clinical | Dr. S. Aldridge Clinical Development | Protocol, single site, 64 volunteers, PK/safety read-out, Clinical Study Report (CSR) | $8,500,000 | 3.9% |
| 1.5 | Phase 2 Clinical | Dr. S. Aldridge Clinical Development | Dose-ranging, 480 participants, 36 weeks, dose selection for pivotal | $38,000,000 | 17.5% |
| 1.6 | Phase 3 Clinical | Dr. R. Molyneux Clinical Operations | Two pivotals plus CV sub-study, 2,480 randomized, 260 sites, 68 weeks | $109,100,000 | 50.3% |
| 1.7 | CMC Scale-Up & Validation | Dr. K. Oyelaran Technical Operations / CMC | Technology transfer, registration batches, Process Performance Qualification (PPQ), stability, method transfer | $9,200,000 | 4.2% |

| 1.9 | Regulatory Affairs | G. Petrossian Regulatory Affairs | Strategy, agency meetings, IND maintenance, labeling negotiation | $7,600,000 | 3.5% |
| 1.10 | Program Management | T. Nakashima Program Management Office | Governance, planning, risk, reporting, gate packages, vendor oversight | $5,300,000 | 2.4% |
| 1.11 | Advisors & Other | T. Nakashima Program Management Office | Regulatory counsel, scientific advisory board, user fees, insurance | $8,400,000 | 3.9% |
| 1.12 | Launch Readiness & Market Access | L. Whitcombe Market Access & Commercial | Payer dossier, launch sequencing, field readiness and market-access execution | $1,000,000 | 0.5% |
| 1.0 Program total | $217,000,000 | 100.0% |
The fact base asserts the mapping on load. Add a WBS node without a matching pool, rename one, or change a Level 3 figure so it no longer sums to its parent, and every artifact in this suite fails to build.
The point of that construction is to remove a recurring failure mode: a WBS and a budget that were consistent when written and drifted apart afterwards, so that scope discussions and cost discussions quietly stop being about the same program.
Each Level 2 node is a control account — the level at which scope, schedule and cost intersect and where a single accountable owner sits. Below that, work packages are assignable and estimable. Above it, roll-up is to the program.
A WBS that decomposed all eleven nodes to equal depth would be a document nobody reads. Depth should follow value and risk — which is why 1.6 and 1.8 are decomposed below and the others are not.
3. Level 3 — Complete Decomposition
65 work packages across all twelve control accounts. Every node decomposes; every set of children sums to its parent. The fact base asserts both.

1.12 — Launch Readiness & Market Access · 1 packages
| WBS | Work package | Scope | Budget |
|---|---|---|---|
| 1.12.1 | Launch readiness & market access | Payer evidence dossier, pricing and reimbursement analysis, launch checklist, and the handover package to the business. Decomposed at re-baseline, not newly funded — this work was always inside this pool and always performed, but was never shown, so the WBS failed the 100% rule it prints in section 1. | $1,000,000 |
| 1.12 total | $1,000,000 |
That has a direct planning consequence. The program's dominant cost driver is participants dosed, not time elapsed. A schedule slip that does not change participant count barely moves these packages; a protocol amendment that adds a visit moves all three.
1.6.5 is the cardiovascular sub-study — scope that did not exist at Gate 4 and arrived from the End-of-Phase-2 meeting as CR-02. 1.7.2 is analytical method transfer, where I-02 originated.
Both could have been absorbed into larger packages. Keeping them discrete means the cost of a scope addition and the cost of a failed transfer stay visible for the life of the program instead of disappearing into a bigger number that nobody questions.
4. Who Owns Each Control Account, and When It Runs
A decomposition that names no one and dates nothing is an inventory, not a plan. Sections 2 and 3 establish what the work is and what it costs. This section establishes who is accountable for each control account and the window it occupies — the two questions a reader asks immediately after seeing the hierarchy.
| WBS | Control account | Control account manager | Window | Bounded by | Duration | Packages |
|---|---|---|---|---|---|---|
| 1.1 | Nonclinical Package | Dr. M. Sørensen Nonclinical Safety & Pharmacology with Dr. P. Ekstrand, Dr. R. Villanueva, Dr. A. Chukwuma | Mar 2022 – Dec 2022 | G0 → G1 | 9 mo | 6 |
| 1.2 | CMC — Early Development | Dr. K. Oyelaran Technical Operations / CMC with Dr. A. Steinhauer, R. Vandenberg, Dr. M. Okonjo | Mar 2022 – Jun 2023 | G0 → G2 | 15 mo | 5 |
| 1.3 | IND Package | G. Petrossian Regulatory Affairs with Dr. A. Whitlock, M. Tsvetkova, J. Oduya | Dec 2022 – Jun 2023 | G1 → G2 | 6 mo | 6 |
| 1.4 | Phase 1 Clinical | Dr. S. Aldridge Clinical Development with Dr. E. Kirchner, Dr. V. Ramaswamy, Dr. B. Osterlund | Jun 2023 – May 2024 | G2 → G3 | 11 mo | 5 |
| 1.5 | Phase 2 Clinical | Dr. S. Aldridge Clinical Development with Dr. C. Mwangi, Dr. T. Halvorsen, Dr. A. Beaumont | May 2024 – Jun 2026 | G3 → G4 | 25 mo | 6 |
| 1.6 | Phase 3 Clinical | Dr. R. Molyneux Clinical Operations with A. Chidambaram, P. Lindqvist, J. Okonkwo | Jun 2026 – Sep 2028 | G4 → G5 | 27 mo | 8 |

| 1.8 | NDA Preparation & Review | G. Petrossian Regulatory Affairs with E. Lindqvist-Brandt, D. Ranganathan, S. Kellerman | Sep 2028 – Oct 2029 | G5 → G6 | 13 mo | 5 |
| 1.9 | Regulatory Affairs | G. Petrossian Regulatory Affairs with R. Amankwah, P. Halvard, N. Escalante | Mar 2022 – Oct 2029 | G0 → G6 | 91 mo | 6 |
| 1.10 | Program Management | T. Nakashima Program Management Office with B. Ferreira, D. Kaufmann, R. Adesanya | Mar 2022 – Oct 2029 | G0 → G6 | 91 mo | 6 |
| 1.11 | Advisors & Other | T. Nakashima Program Management Office with B. Ferreira, D. Kaufmann, R. Adesanya | Mar 2022 – Oct 2029 | G0 → G6 | 91 mo | 5 |
| 1.12 | Launch Readiness & Market Access | L. Whitcombe Market Access & Commercial with Dr. C. Bergstrom, A. Villasenor, M. Oyelowo | Sep 2028 – Oct 2029 | G5 → G6 | 13 mo | 1 |
The distinction is worth stating because the opposite mistake is common: a resource-loaded WBS with dates typed against every package, drifting from the schedule within a month of baseline.
1.9, 1.10 and 1.11 span the whole program — regulatory affairs, program management and advisory cost are not phases, they are continuous obligations. Showing them with the same start and end as the program is not a defect in the decomposition; it is what a level-of-effort account looks like, and it is why they are measured on spend against plan rather than on milestone completion.
5. Resource Model
109 people across ten functions, 191,420 hours, representing $36,008,000 — 16.6% of base.
| Function | Function lead | Headcount | Hours | % of roster | Scope | Note |
|---|---|---|---|---|---|---|
| Clinical Operations | Dr. R. Molyneux Senior Director, Clinical Operations | 24 | 51,900 | 22.0% | Sites, monitoring, enrolment, clinical supply | Largest function. Scales with site count, not with program value — and it oversees a CRO rather than executing the trial itself. |
| Technical Operations / CMC | Dr. K. Oyelaran VP, Technical Operations (CMC) | 16 | 30,200 | 14.7% | Process, analytical methods, scale-up, validation | Peaks late, when clinical is winding down. CMC gates the filing independently. |
| Clinical Development | Dr. S. Aldridge VP, Clinical Development | 12 | 17,900 | 11.0% | Protocols, medical monitoring, clinical study reports | Small headcount, high rate — medical monitors are physicians. |
| Biostatistics & Data Management | Dr. F. Achterberg Head of Biostatistics | 12 | 22,600 | 11.0% | SAP, EDC, database lock, analysis datasets | Under-resourced in most programs relative to what the filing actually needs. |
| Regulatory Affairs | G. Petrossian Director, Regulatory Operations | 10 | 18,900 | 9.2% | Strategy, submissions, agency interaction, labeling | Highest blended rate in the program. Ten people carry every commitment made to the agency. |
| Pharmacovigilance & Drug Safety | Dr. N. Halloran Head of Pharmacovigilance | 8 | 14,200 | 7.3% | Case processing, signal detection, DSUR | Carries an expedited-reporting clock that has no tolerance band. |
| Quality Assurance (Good [Clinical/Laboratory/Manufacturing] Practice (GxP)) | Dr. I. Solberg Chief Quality Officer | 7 | 12,800 | 6.4% | Audits, Corrective and Preventive Action (CAPA), GxP compliance, inspection readiness | Independent of every function it audits; the CQO reports to the CEO, not to this program. |
| Nonclinical Safety & Pharmacology | Dr. M. Sørensen VP, Nonclinical Safety | 5 | 9,400 | 4.6% | Toxicology, pharmacology, study oversight | Front-loaded — near zero after Gate 2, which is why headcount alone misstates its importance. |
| Program Management Office | T. Nakashima VP, Program Delivery | 4 | 7,200 | 3.7% | Governance, planning, risk, reporting | 3.7% of headcount coordinating the other 96.3%. |
| Market Access & Commercial | L. Whitcombe Director, Market Access | 4 | 5,000 | 3.7% | Payer evidence, pricing, launch readiness | Joint-smallest, latest to staff, and lowest hours per head — while carrying the longest-lead assumption in the business case. |
| Total | 109 | 191,420 | 100% |
83% of the budget is external — the CRO, the contract manufacturer, the central laboratory, sites, advisors and fees. So a program manager who manages headcount tightly and vendor commitments loosely has optimized the small number.
It also means the resource plan is not primarily a staffing plan. It is a contracting plan with a staffing plan attached, which is why the CRO Oversight Plan carries more of this program's cost control than this document does.
That is not an argument for a bigger market access team. It is an observation that the function carrying the assumption with the longest lead time was the one resourced last, and that GC-03 was the governance system noticing exactly this and being unable to fix it with a condition.
6. What Is Deliberately Outside the WBS
- Commercial launch investment. Field force, marketing, distribution build. Separate authorization; not this program's scope (Charter §4).
- European filing. Explicitly out of scope. Deferred to Year 4+.
- Post-approval commitments. PMR-1 and PMR-2 report in 2034 and 2035, under permanent functions, after this program has closed.
- Second indication work. Platform option value is a benefit, not a deliverable.
- Line-function base costs. Quality systems, facilities and IT that exist whether or not this program does.
The last exclusion is the one that causes arguments. Line-function costs are real and the program consumes them, but they are not caused by the program and would not disappear if it stopped. Loading them in would make the program look more expensive than it is and make its cost per deliverable incomparable with any other program.
7. How This WBS Is Used
| Use | How |
|---|---|
| Scope control | New work must be assigned a WBS node. Work that fits no node is a change, and goes to change control rather than into someone's week. |
| Cost roll-up | Actuals are booked to work packages and roll to control accounts and to the program. The budget and this structure are the same numbers. |
| Schedule development | Activities are derived from work packages, not invented alongside them. The schedule decomposes 1.x nodes into sequenced activities with durations. |
| Responsibility assignment | Each control account has one accountable owner. The Responsible, Accountable, Consulted, Informed (RACI) matrix maps functions to nodes. |
| Risk association | Every risk in the RAIDD Log attaches to a WBS node, so exposure can be read by deliverable rather than only by register. |
| Contingency reasoning | A draw is assessed against the node it protects. CR-02 sits at 1.6.5; I-02 at 1.7. |
When a risk attaches to a node, a program manager can answer “how much of the program is exposed to this?” with a number rather than an adjective. When a contingency draw is assessed against a node, the question “is this recovery or is it new scope?” has an answer — recovery restores a node to its planned state, new scope creates or expands one.
That distinction is the whole basis of the Contingency Register's discipline about what the reserve does and does not fund.
