Dossier Preparation & Submission Service

In the competitive landscape of global biotechnology, the technical dossier is the single most critical asset between laboratory innovation and commercial reality. At Protheragen, we recognize that a dossier is not merely a collection of data; it is a persuasive scientific narrative that must withstand the rigorous scrutiny of global health authorities like the FDA and NMPA. Our regulatory filing & dossier synthesis team delivers a holistic partnership for life sciences innovators, meticulously distilling intricate research findings into high-fidelity, submission-ready CTD and eCTD packages. By integrating regulatory intelligence with deep scientific expertise, we ensure that your candidate drug's safety, efficacy, and quality are presented with absolute clarity to minimize "Refuse to File" (RTF) risks and accelerate approval timelines.

We address critical questions such as optimal registration pathways, eligibility for priority review, and the strategic use of foreign clinical data.

• Global Strategy Formulation: Tailoring registration plans that align with NMPA, FDA, and EMA requirements, including specialized "Dual-Filing" (Sino-US) strategies.
• Feasibility & Pre-audit Assessment: Conducting gap analysis between original country data and local requirements to identify potential roadblocks early in the development cycle.
• Regulatory Intelligence Updates: Leveraging reforms such as the shortened CTA approval timeline (now 60 working days) and improved IP protection standards to benefit your project.

• Comprehensive IND/CTA & Clinical Trial Applications

Utilizing our AI-driven gap analysis engine, we manage the entire clinical trial application process, ensuring dossiers meet the highest scientific standards.

• Sino-US Dual Filing for IND: Coordinating simultaneous investigational new drug applications to streamline global development timelines.
• Center for Drug Evaluation (CDE) Engagement & Consensus Building: Facilitating high-level formal and informal consultations with the CDE to navigate intricate technical bottlenecks and secure agency alignment on pivotal trial protocols.
• Fast-track Documentation: Professional preparation of Investigator's Brochures (IB), clinical protocols, and specialized medical translations.

• Full-Scale NDA/BLA/MAA Preparation & Submission

For late-stage programs, we deploy predictive regulatory modeling to compile and manage full marketing authorization applications.

• Scientific Narrative & Dossier Compilation: Expert authoring and auditing of content through Module 5, ensuring the candidate drug's safety and efficacy profile is presented with technical precision.
• Post-Submission Liaison: Proactive tracking of the review status and rapid-response strategies for addressing deficiency letters or expert panel queries.
• On-site Audit & Inspection Support: Assisting clients in preparing for pre-approval inspections (PAI) and official laboratory testing coordination.

• Precision CMC & DMF Lifecycle Management

Our CMC specialists ensure that the chemistry, manufacturing, and controls sections are robust and compliant with global GMP standards.

• Module 3 & DMF Services: Preparation of drug master files (Type II, III, IV) and ensuring technical integrity across stability reports and batch records.
• Gap Analysis for Local Requirements: Analyzing data deficiencies between global manufacturing standards and specific regional pharmacopeia.

• eCTD Publishing & Global Market Access

Powered by our eCTD 4.0 Compliant Publishing Suite, we manage the digital lifecycle of your submissions.

• Electronic Submission Management: Seamless compilation and validation of eCTD sequences for multiple jurisdictions (NMPA, FDA, EMA).
• Lifecycle Maintenance: Managing post-approval variations, annual reports, and license renewals to ensure continuous compliance throughout the product lifecycle.
