How We Compare

Criterion Edge

Generalist CROs

Regulatory and scientific medical writing for pharmaceutical and biotechnology companies

Criterion Edge provides specialized regulatory and scientific medical writing for pharmaceutical and biotechnology companies. Our writers support individual documents, complex submission programs, and ongoing development portfolios from early clinical planning through marketing applications and postapproval commitments.

What We Do

Criterion Edge provides specialized regulatory and scientific medical writing for pharmaceutical and biotechnology companies. Our writers support individual documents, complex submission programs, and ongoing development portfolios from early clinical planning through marketing applications and postapproval commitments.

Our pharmaceutical writing services support:

Emerging biotechnology companies building their first regulatory submission
Pharmaceutical sponsors managing multiple studies or development programs
Clinical and regulatory teams preparing INDs, NDAs, BLAs, and global submissions
Organizations needing experienced writing leadership without adding permanent headcount
Teams facing compressed timelines, document backlogs, or inconsistent source materials
Sponsors requiring independent quality control or remediation of existing documents

The Problem It Solves

Regulatory submissions require more than technically accurate documents. Information must remain scientifically sound, internally consistent, traceable to source data, aligned across functions, and presented in a format that allows reviewers to understand the development rationale quickly.

Criterion Edge helps sponsors:

Convert complex data and multidisciplinary input into clear regulatory narratives
Maintain consistency across clinical, nonclinical, CMC, and summary documents
Coordinate reviews and resolve conflicting stakeholder comments
Identify documentation gaps before they affect submission timelines
Scale writing resources to meet changing program demands
Keep submission-critical documents moving when internal teams are at capacity

What You'll Gain

Accelerate Submission Readiness

Keep critical documents moving through structured planning, proactive timeline management, and experienced writing support.

Reduce Review Cycles

Receive focused, submission-ready drafts that reflect source documentation, regulatory expectations, and agreed messaging before broad stakeholder review.

Improve Cross-Document Consistency

Maintain aligned language, data presentation, terminology, conclusions, and key messages across the submission package.

Expand Capacity without Sacrificing Quality

Scale from one experienced writer to a coordinated writing team based on document volume, therapeutic complexity, and timeline.

Strengthen Regulatory Narratives

Present the scientific rationale, development strategy, benefit-risk profile, and supporting evidence in a clear and defensible manner.

Why Choose Us

Experienced Regulatory Writers

Projects are led by experienced medical writers with pharmaceutical, biotechnology, clinical development, and submission experience—not simply assigned based on availability.

Submission-Level Perspective

We evaluate each document within the context of the broader development program and submission package. Our writers consider how data, conclusions, terminology, and key messages carry across documents.

Flexible Team Structure

Criterion Edge can provide:

A single embedded writer
A lead writer supported by specialist contributors
A coordinated team for parallel document development
Writing leadership and review management
Independent QC support
Short-term remediation or long-term portfolio support

Therapeutic and Scientific Dept

Our team includes PhD-level scientists, experienced clinical and regulatory writers, medical librarians, and specialist consultants with experience across multiple therapeutic areas and product types.

Structured Quality Control

Quality is incorporated throughout document development rather than treated as a final formatting exercise. Each project uses defined writing, review, comment-resolution, and QC processes tailored to the deliverable.

Collaborative Approach

Our writers work directly with clinical, regulatory, safety, statistics, nonclinical, CMC, and subject matter experts to produce documents that reflect both the data and the sponsor’s development strategy.

Clear Scoping and Budgeting

Projects are scoped according to the available source documentation, document maturity, stakeholder structure, review expectations, and timeline. Clients receive clear assumptions and defined deliverables before work begins.

How it works

A writing process built for complex, cross-functional programs

Step 1: Project Scoping and Source Assessmen

We define the deliverables, objectives, regulatory context, available source documents, document dependencies, review team, and target timeline.

Key activities may include:

Step 2: Content Planning and Message Alignement

The lead writer develops the document strategy, outline, data presentation plan, and key messages before full drafting begins.

For submission programs, this step may also include:

Step 3: Document Development

The writer prepares the document using approved source materials, applicable guidance, sponsor templates, and agreed messaging.

Throughout development, the team provides:

Step 4: Collaborative Review and Comment Resolution

Criterion Edge supports a structured review process designed to prevent circular or conflicting revisions.

Support may include:

Step 5: Quality Control and Finalization

The document undergoes the agreed level of scientific, editorial, data, formatting, and consistency review before delivery.

Finalization may include:

Frequently Asked Questions

What pharmaceutical and biologics documents does Criterion Edge write

Criterion Edge supports regulatory, clinical, safety, nonclinical, CMC, and scientific documents across the product lifecycle. Common deliverables include protocols, clinical study reports, investigator’s brochures, patient narratives, briefing documents, INDs, NDAs, BLAs, CTD summaries and overviews, development safety update reports, manuscripts, abstracts, and submission responses.

Can Criterion Edge support an entire IND, NDA, or BLA?

Yes. We can support a complete submission writing program, selected CTD modules, or individual documents. The team structure depends on the number of deliverables, source-document readiness, submission timeline, and level of strategic writing leadership required.

Can you provide only one medical writer?

Yes. Criterion Edge can provide a single writer for a defined deliverable or an embedded writer who works alongside the sponsor’s internal team. We can also scale to a lead writer and coordinated document team when the program expands.

Can your writers work directly with our subject matter experts?

Yes. Our writers routinely collaborate with clinical, regulatory, pharmacovigilance, biostatistics, nonclinical, CMC, and other subject matter experts. We can participate in working meetings, lead document reviews, track action items, and help resolve conflicting comments.

Can you work from incomplete source documents?

Often, yes. During scoping, we assess which materials are available and identify gaps that could affect the document. We can begin with agreed assumptions when appropriate, but critical missing data, analyses, or strategic decisions may need to be resolved before portions of the document can be finalized.

Do you provide regulatory strategy?

Criterion Edge provides document strategy, content planning, gap assessment, and submission-focused writing guidance. When a project requires a formal regulatory opinion or agency-interaction strategy outside the writing scope, we can work with the sponsor’s regulatory lead or an appropriately qualified regulatory consultant.

Do you offer independent quality control?

Yes. We provide independent scientific, editorial, data, reference, formatting, and consistency reviews. The QC scope can be tailored to an individual document or an entire submission package.

Can you follow our templates and style guides?

Yes. We routinely work within sponsor templates, document standards, controlled terminology, and style guides. We can also create or revise templates and style guides when existing standards are incomplete or inconsistent.

Can you support accelerated timelines?

Yes. Criterion Edge uses a flexible staffing model that can support parallel drafting, dedicated writing teams, and focused review coordination. Feasibility depends on source readiness, document complexity, stakeholder availability, and the number of review cycles required.

How long does it take to complete a pharmaceutical regulatory document?

Timelines vary considerably by document type, data availability, document maturity, complexity, and review structure. A clear timeline is developed during scoping after we assess the source materials, dependencies, and required review cycles.

Can you remediate a document that another writer or vendor started?

Yes. We can assess, revise, complete, or independently review partially drafted or legacy documents. The initial assessment identifies structural, scientific, consistency, source-document, and formatting issues before the remediation scope is finalized.

How do you maintain consistency across a submission?

We establish shared terminology, source-document conventions, data presentation standards, and key messages at the beginning of the program. A lead writer or writing manager then oversees cross-document alignment, content reuse, and consistency throughout development and review.

Do you support global submissions?

Yes. Criterion Edge supports documents intended for major global regulatory authorities. During scoping, we confirm the target jurisdictions, submission format, applicable guidance, and opportunities to reuse core content while adapting documents to jurisdiction-specific expectations.
