Pharma Regulatory Services in the US: Case Studies of How Navitas Life Sciences Supports Strategic Submissions for Market Success

The United States remains a global leader in the life sciences industry, offering immense opportunities for pharmaceutical and medical device companies worldwide. As one of the most advanced and tightly regulated markets, U.S. requires strict adherence to the U.S. Food and Drug Administration’s (FDA) evolving guidelines. The complex regulatory environment shaped by ongoing changes in registration requirements, technological innovation, and GxP expectations can pose challenges for companies aiming to ensure compliant and timely market access.

Navitas Life Sciences is headquartered in the U.S. and brings deep-rooted expertise in FDA regulatory consulting services. As a trusted US regulatory partner, we support global pharmaceutical and medical device manufacturers in achieving regulatory compliance within the U.S. framework. Our clinical regulatory services encompass everything from US regulatory strategy and IND support to post approval submission support for biopharma, enabling sponsors to streamline submissions, reduce risk, and accelerate approvals across the product lifecycle. We offer specialized regulatory services for startups, provide expert clinical study report review, and deliver actionable FDA IND guidance tailored to each development stage, ensuring comprehensive and compliant regulatory outcomes.

A Strategic Partner for U.S. Market Entry

Expert Support for FDA Submission Pathways

The U.S. FDA recognizes multiple regulatory pathways based on the type and novelty of the drug product. These include:

• Investigational New Drug (IND) Applications – For drugs not yet approved for any indication and intended for clinical trials.
• New Drug Applications (NDAs) – For novel drugs seeking marketing authorization.
• Abbreviated New Drug Applications (ANDAs) – For generic equivalents of already approved reference drugs.
• 505(b)(2) NDAs – For products that bridge existing data with new data (e.g., reformulations or combination products).
• Biologics License Applications (BLAs) – For biologic products such as vaccines, monoclonal antibodies, and cell therapies.
• Drug Master Files (DMFs) – For submission of confidential information about facilities, processes, or components used in manufacturing.

Navitas Life Sciences brings proven proficiency in compiling, reviewing, and submitting these applications in eCTD (electronic Common Technical Document) format, aligned with the FDA’s structured regulatory submission requirements. Our comprehensive services also cover pre- and post-submission support, regulatory correspondence, lifecycle management, and change control with the technology support for management and tracking.

Real-World Success Stories

Case Study 1: Empowering a U.S.-Based Startup with IND CMC Authoring and Strategy

A U.S.-based startup pharmaceutical company approached Navitas Life Sciences as it prepared for its first IND submission. The sponsor was looking for a vendor that could provide high-quality CMC regulatory authoring, expert review, and FDA-aligned strategic guidance—all while staying within budget.

Our Solution

We deployed a hybrid regulatory team:

• A U.S.-based Project Manager and experienced CMC Strategist to engage directly with the client and provide scientific and regulatory insights
• A team of subject matter experts (SMEs) based in India to manage documentation, accelerate turnaround times, and drive cost efficiency

The CMC Strategist guided the client on FDA expectations specific to biologics, identified data gaps early, and proposed remediation steps. Using our in-house IND authoring template, we compiled Module 2 & 3 (Quality) with scientific justifications for any data deviations or limitations, ensuring robust regulatory alignment.

The Outcome

• Submission delivered on time with 100% SLA adherence
• Clear, data-driven messaging that aligned with FDA regulatory standards
• Proactive identification and resolution of gaps, reducing risk of post-submission RFIs
• Seamless collaboration via MS Teams for real-time updates

The client was highly impressed with the strategic value delivered. Recognizing the quality of support, they extended the scope of engagement to include medical writing services and scientific review of clinical phase study reports.

Case Study 2: U.S.-Only Regulatory Publishing and Submission Support for a Mid-Sized Pharma

A mid-sized pharmaceutical company required urgent regulatory publishing support for its US IND applications, with the unique requirement that all services be delivered exclusively from within the U.S. This meant having Publishing teams based onshore who could quickly adapt to client systems, ensure secure data handling, and maintain a high degree of responsiveness.

Our Solution

• Navitas assembled a dedicated U.S.-based delivery team, including:
• A local Project Manager/Point of Contact to ensure alignment with client stakeholders
• Deployed a ‘Ready to Go’ Publishing team trained on pharmaREADY tool
• Real-time MS Teams communication to coordinate urgent submissions and client approvals

The team successfully completed multiple submissions under tight deadlines, maintaining high accuracy, compliance, and efficiency throughout.
