How to Get a Senior Regulatory Opinion Fast
There is a particular kind of regulatory question that does not need a project. It needs an answer. A specific, expert, well-reasoned answer from someone who has dealt with exactly this type of issue before, and who can give you a clear steer within hours or days, not weeks.
The problem is that the traditional consultancy model is not built for this. Scoping calls, statements of work, onboarding processes, account management overhead: the machinery required to engage a consultancy formally is often entirely disproportionate to the question being asked.
This article is for the regulatory leads, CMC directors, heads of development, and biotech founders who know what they need and simply want to know how to get it, quickly and without unnecessary process.
1. The Questions That Fall Through the Gap
Most organisations have a reasonable handle on their planned regulatory workload. Submission timelines, agency meeting preparation, dossier development: these are managed, resourced, and tracked. What is harder to manage is the unplanned question, the one that arrives mid-programme and demands an informed answer before you can move forward.
These questions take many forms:
You are preparing a Type B meeting request and want a sense-check on your proposed questions before you submit.
A CMC change has arisen during development and you need to understand whether it triggers a variation, and if so, what level.
Your clinical team is questioning whether the current dosing rationale will withstand regulatory scrutiny at end of Phase II.
You have received a regulatory query from a partner or licensor and need an expert second opinion before you respond.
You are considering a development strategy change and want to understand the regulatory risk before you commit.
Your in-house regulatory resource is strong on submissions but less experienced in a specific therapeutic area or market, and you need someone who knows that territory well.
None of these require a project. All of them require expertise. And the gap between those two things is where programmes lose time.
2. Why the Traditional Consultancy Model Often Does Not Fit
The formal consultancy engagement model exists for good reasons. It provides structure, accountability, and a clear framework for managing complex, extended pieces of work. For large projects, it is the right approach.
For a focused expert opinion, it creates friction at every stage.
The scoping problem
A formal engagement typically begins with a scoping exercise. This is designed to protect both parties, but it adds time and introduces an initial conversation about cost and scope before any substantive work has been done. When the question is specific and bounded, this process can feel like being asked to complete a procurement exercise before being allowed to ask a question.
The mobilisation problem
Once a project is scoped and agreed, there is typically a mobilisation period before a senior consultant is actively engaged. Depending on the firm and the complexity of the setup, this can run from a few days to a few weeks. For a time-sensitive regulatory question, that lag is often unacceptable.
The relationship problem
In a large consultancy, the person who sells the project is rarely the person who does the work. The senior expert whose opinion you actually want is frequently several layers removed from the initial engagement. What you receive may be the considered view of a competent junior consultant, reviewed and signed off by a senior, rather than a direct conversation with the most experienced person in the room.
The cost problem
Formal projects carry overhead: project management, reporting, account management, administration. For a bounded expert opinion, you are paying for infrastructure you do not need. The cost is rarely proportionate to the work.
The Core Issue
The traditional consultancy model is optimised for projects. Most regulatory questions are not projects. They are questions. The two require different approaches.
3. What a Senior Regulatory Opinion Actually Looks Like
When the model is right, getting a senior regulatory opinion quickly is straightforward. It looks like this:
You have a specific question. You speak directly with a senior consultant who has relevant experience in the therapeutic area, the regulatory market, and the type of question you are asking. That conversation is substantive from the first minute. You come away with a clear expert view, the reasoning behind it, and a sense of the key risk or uncertainty factors you need to manage.
In some cases, the opinion is delivered verbally in a single call. In others, it is followed up with a short written summary. Either way, the total elapsed time from first contact to informed answer is measured in days, not weeks.
What it is not: a lengthy report, a formal deliverable with an executive summary and a methodology section, or a document that has been produced by someone junior and reviewed by someone senior. It is direct access to expertise, applied to your specific situation.

4. The Situations Where This Approach Adds Most Value
Not every regulatory question is suited to an informal expert opinion model. Some situations genuinely do require a structured project with formal deliverables, accountability frameworks, and extended engagement. But a significant proportion of time-sensitive regulatory questions do not, and recognising the difference is important.
The approach works particularly well in the following situations:
Strategic inflection points
When a programme is at a decision point and the regulatory dimension is a key input, a fast senior opinion can be the difference between a well-informed decision and one made in the absence of expert input. This is especially true in smaller organisations where the internal regulatory function may not have deep experience across all relevant markets or modalities.
Pre-meeting preparation
Agency meetings are high-stakes interactions. An expert review of your proposed questions, your briefing document, or your anticipated agency responses can materially improve the quality of your meeting. This kind of focused input is well suited to the rapid opinion model and does not require a full meeting preparation project.
Responding to unexpected agency feedback
When the agency responds to a submission or raises a query outside the expected scope, the clock starts immediately. Understanding what the agency is really asking, what the appropriate response looks like, and what the strategic implications are is exactly the kind of expert input that needs to arrive in hours, not after a formal scoping exercise.
Licensing and partnering due diligence
Regulatory risk is a material factor in any licensing or partnering transaction. A fast expert opinion on the regulatory profile of an asset, a development strategy, or an agency relationship can inform a negotiating position or flag a risk that changes the shape of a deal.
Cross-market questions
An organisation with strong regulatory expertise in one market will sometimes face questions about a second market where their internal knowledge is thinner. Whether that is a question about PMDA expectations, Health Canada requirements, or the regulatory implications of a post-Brexit UK strategy, a direct conversation with someone who knows that market in depth is often all that is required.
5. How to Get the Most From a Focused Expert Engagement
The quality of a rapid expert opinion is directly related to the clarity of the question being asked. This is worth investing time in before the conversation begins.
Define the question precisely
There is a significant difference between ‘we have a CMC question’ and ‘we have made a manufacturing site change during Phase III and need to understand whether this requires a prior approval variation or a notification, and what the implications are for our planned NDA submission timeline.’ The second question enables a much more useful answer.
Provide relevant context upfront
A senior consultant can give a sharper opinion when they have the relevant background: the regulatory history of the programme, the current development stage, the markets in scope, and any prior agency feedback that is pertinent. This does not require a comprehensive briefing document. A concise summary shared before the call is usually sufficient.
Be clear about what you need from the output
Do you need a verbal steer to inform an internal decision? A written opinion you can share with your board or partner? A recommended course of action with the associated risk profile? Being clear about the intended use of the opinion allows the consultant to calibrate their response appropriately.
Know when to escalate
A focused expert opinion is the right tool for a bounded question. If the conversation reveals that the question is more complex than initially understood, or that the answer has implications that require broader analysis, the right response is to recognise that and commission the appropriate level of work. A good consultant will tell you clearly when a rapid opinion is sufficient and when it is not.
A Note on Quality of Access
The value of a rapid expert opinion depends entirely on the seniority and relevance of the expert. When evaluating whether to use this model, the question to ask is not only how quickly can I get an answer, but who will I actually be speaking to, and do they have direct experience of this type of question.
6. Building Rapid Expert Access Into Your Operating Model
Organisations that manage regulatory risk well tend to have established relationships with expert advisors they can call on quickly, without process overhead, when the need arises. This is not an accident. It is a deliberate operating model decision.
The alternative is to build the relationship at the point of need, which almost always means the first conversation is partly about establishing credibility and context rather than immediately addressing the question. Time is lost, and the quality of the initial input is lower than it would be with an established advisor.
There are practical ways to build this kind of readiness:
Identify two or three regulatory advisors with relevant expertise before you need them. Understand their availability model, their areas of deepest knowledge, and how they prefer to work.
Have an initial conversation that is genuinely exploratory rather than project-specific. Understanding how a consultant thinks before you need their opinion on a live question is valuable.
Use smaller, focused engagements to build the relationship over time. An advisor who has given you three or four focused opinions on earlier questions will be significantly more useful on a high-stakes question than one you are engaging for the first time.
Maintain clear documentation of your regulatory history and programme context so that a new conversation with an expert can begin at the substantive level immediately.

7. The Broader Point: Regulatory Agility as a Competitive Advantage
Speed of regulatory decision-making is increasingly a differentiating factor in pharmaceutical development. Organisations that can assess a regulatory question quickly, make an informed decision, and move forward without waiting for the next scheduled review or the conclusion of a lengthy consultancy engagement are faster, more adaptive, and less exposed to the kind of regulatory uncertainty that delays programmes.
Access to rapid senior expertise is one component of that agility. It sits alongside well-maintained regulatory intelligence, strong internal regulatory capability, and established relationships with the agencies themselves. None of these elements replaces the others. Together, they create an organisation that is genuinely equipped to navigate a regulatory environment that is complex, evolving, and unforgiving of slow decision-making.
The question is not whether you will need expert regulatory input at short notice. You will. The question is whether you have the relationships and the access model in place to get that input when the need arises, or whether you will find yourself starting from scratch at the worst possible moment.
Final Thought
Senior regulatory expertise is not a commodity. Finding someone with the right combination of therapeutic area knowledge, agency experience, and strategic judgement to answer a specific question well takes time if you are starting from scratch. The organisations that access it most effectively are those that have invested in those relationships before the urgent question arrives.
If you have a question that needs a fast, expert answer, the right first step is a direct conversation with someone who has genuinely dealt with this type of question before. Not a scoping call. Not a proposal. A conversation.
That is what good regulatory advisory access looks like. And it is available, if you know where to find it.
