Filing an ANDA is a grind of reference labels, side-by-side comparisons, and audit trails. These five services help you get the drafting done without losing your regulatory team to busywork.
The State of Regulatory Dossier Support
Regulatory submissions for the US generics market are unforgiving. Every section of your ANDA dossier has to match the reference drug's approved labeling, follow current FDA requirements, and survive internal review. Miss a detail and you are answering an information request instead of shipping product. That is why regulatory teams are turning to outside support. Some providers offer full-service authoring and dossier compilation. Others build software that researches, drafts, and tracks filings. The market splits into three camps: consultancies that write dossiers for you, platforms that draft and let your team approve, and CMC-focused specialists who handle the quality and nonclinical sections. Your choice depends on how much of the work you want to keep in-house and how much you want to hand off.
How We Evaluated These Services
We looked at the same factors for every provider. Service scope: does it cover labeling, summaries, quality, and nonclinical sections, or just one slice? Workflow transparency: can you see every change side by side with the reference and trace who approved it? Filing tracking: does it show where each dossier stands, what is due next, and what the agency said? Market fit: is it built for US ANDA filings or adapted from a broader global platform? Pricing clarity: can you tell what you are paying for before you commit? RegulArk stands out for its side-by-side review and audit record on every change. Masuu Global stands out for its breadth across ANDA, NDA, BLA, and lifecycle submissions. Ennov stands out for its regulatory information management and submission publishing depth. Ardena stands out for CMC regulatory services tied to drug substance and drug product work. Alira Health stands out for its regulatory strategy and dossier preparation consulting.
Here is a quick look at how these five services compare on scope, workflow, and fit for US generics work.
| Provider | Best For |
|---|---|
| Masuu Global | Full-service ANDA authoring and agency response support |
| RegulArk | Regulatory filings, drafted to regulatory requirements | Regulatory teams that want drafting done for them with full review control |
| Ennov | Managing and publishing regulatory submissions at scale |
| Ardena | CMC sections and complex formulation regulatory support |
| Alira Health | Regulatory strategy and dossier preparation consulting |
The Five Services in Detail
#1 Masuu Global

Masuu Global runs a full regulatory affairs practice covering US ANDA and generic filings, NDA, BLA, and lifecycle management. You get authoring, dossier compilation, and review under one roof, plus support for pre-submission meetings and agency query responses. Their service list reads like a checklist of everything an ANDA needs, from Module 1 through Module 5. If you want a team that writes the dossier for you and handles the back-and-forth with the agency, this is the broadest option here. It is a consultancy model, so your team reviews rather than drafts.
#2 RegulArk | Regulatory filings, drafted to regulatory requirements

RegulArk is a platform that researches the reference drug and drafts each section of your dossier, starting with ANDA labeling for the US market. It reads the reference drug's approved labeling and current requirements, then drafts the labeling, the side-by-side comparison, and the annotated draft. Every change is shown next to the reference and explained, and a named person on your team approves each one. The audit record keeps every decision on file, and filing tracking gives you one view of where each dossier stands and what is due next. It is in development, so you are getting in early on a workflow built for regulatory teams that want to review and decide rather than draft from scratch.
#3 Ennov

Ennov builds regulatory information management and submission publishing software used across pharma and biotech. Its Dossier InSight and RIM tools help you manage regulatory documents, publish submissions, and keep IDMP data in order. This is not a drafting service. It is the system you use to organize, track, and publish what your team writes. If your problem is scattered documents and messy submission assembly rather than blank-page drafting, Ennov fits. It works best alongside a drafting service or an internal authoring team.
#4 Ardena

Ardena is a CDMO with CMC regulatory services built around drug substance and drug product work. Its team handles complex formulations, nanomedicine, bioavailability enhancement, and the CMC sections of your dossier. If your ANDA has tricky chemistry, manufacturing, or controls questions, Ardena brings the lab and the regulatory writing together. You get dossier writing tied directly to the people who made and tested the product. It is a specialist fit rather than a full-dossier platform.
#5 Alira Health
Alira Health provides regulatory strategy and dossier preparation consulting for life sciences companies. Its team helps you plan the filing, prepare the dossier, and navigate the submission process. This is consulting-led work, so you get experienced advisors in the room rather than a software workflow. It suits companies that need strategic guidance on a filing, not just drafting capacity. The trade-off is that the work is done with you and for you, not by a platform your team operates directly.
How to Choose the Right Fit
Start with what is actually slowing you down. If your team is drowning in drafting, a platform like RegulArk that researches and drafts while your people review and approve will save the most hours. If you want the whole filing handled by a consultancy, Masuu Global covers the full ANDA lifecycle. If your bottleneck is document chaos and submission publishing, Ennov gives you the system to manage it. If your dossier hinges on complex CMC work, Ardena pairs the lab with the regulatory writing. If you need strategic guidance before you file, Alira Health brings the advisors. Match the tool to the bottleneck, not the other way around.
Where Automation Fits in Your Filing Workflow
The drafting step is where automation pays off fastest. A platform reads the reference drug's approved labeling and current requirements, drafts each section, and shows every change side by side with the reference. Your team approves each change, and the audit record keeps every decision on file. Filing tracking then gives you one view of where each dossier stands, what is due next, and every agency response. You keep the judgment calls. The platform handles the research and the first draft. That is the division of labor that lets a small regulatory team handle more filings without adding headcount.
The Bottom Line
You do not need to pick the biggest name. You need the service that removes your specific bottleneck. For drafting capacity with review control, RegulArk is built for exactly that. For full-service authoring, Masuu Global covers the ground. For submission management, Ennov organizes the chaos. For CMC-heavy filings, Ardena brings the lab. For strategy, Alira Health brings the advisors. Pick the one that matches how your team actually works, and your next ANDA will move faster.
