Strategic Regulatory Pathway to Success

Obtain the expertise and the solutions you need from a dedicated, successful team who knows how to navigate the FDA’s regulatory and oversight processes.

Our team has successfully guided novel drug and biologic companies through the complex FDA approval process. Our approach is designed to overcome regulatory hurdles and minimize product development time, risk, and cost.

Each year we prepare a wide variety of agency submissions for novel small and large molecules, biosimilars, and generic drugs. Our team has achieved a 100% success rate with on-time Investigational New Drug (IND) application submissions.

Our goal is to develop strategies that align with our clients’ interests so that they may remain focused on what they do best: innovating and developing the next generation of successful therapeutics.

We offer clients a head start through our deep understanding of the regulatory expectations and the guidance required to achieve success at each milestone during the development of a novel drug. This includes a thorough assessment of your existing data, prior regulatory filings, and the latest FDA guidances.

      FDA Meeting Types

      There are five types of meetings that occur between drug sponsors or applicants and FDA staff: INTERACT, Type A, Type B, Type C, and Type D. Each meeting type is subject to different procedures, as described below.


      The INTERACT (Initial Targeted Engagement for Regulatory Advice on CBER/CDER products) Meeting is a meeting intended to facilitate IND-enabling efforts when the sponsor is facing a novel, challenging issue that might otherwise delay progress of the product towards entry into the clinic. The INTERACT meeting:

      • Provides an opportunity for preliminary informal feedback on CMC, preclinical, and clinical issues for innovative investigational products
      • Occurs early in development, prior to the stage when a pre-IND meeting might be requested
      Type A Meeting

      Type A meeting is a meeting needed to help an otherwise stalled product development program proceed. Examples of a Type A meeting include:

      • Dispute resolution meetings
      • Discussion of clinical holds
      • Special protocol assessment meetings

      Type A meetings are scheduled to occur within 30 days of FDA receipt of the written meeting request.

      Type B Meeting

      Type B meetings include:

      • Pre-investigational new drug application (pre-IND) meetings
      • Certain end-of-phase 1 meetings
      • End-of-phase 2 (EOP2) and pre-phase 3 meetings
      • Pre-new drug application/biologics (pre-NDA/BLA) license application meetings

      Type B meetings are scheduled to occur within 60 days of FDA receipt of the written meeting request. Generally, the FDA will not grant more than one of each of the Type B meetings for each potential application.

      Type C Meeting

      A Type C meeting is any meeting other than a Type A or Type B meeting between FDA CBER or CDER and a sponsor or applicant regarding the development and review of a product.

      Type C meetings are scheduled to occur within 75 days of FDA receipt of the written meeting request.

      Type D Meeting

      A Type D meeting is focused on a narrow set of issues (limited to no more than 2 focused topics) and should not require input from more than 3 disciplines or Divisions.

      Type D meetings are scheduled to occur within 50 days of FDA receipt of the written meeting request.

      CSSi LifeSciences has extensive experience in meeting-document preparation and can provide you with best practices for a successful FDA meeting.

      Integrated Project Management

      CSSi LifeSciences provides all the relevant consulting and embedded management capabilities required to support drug discovery from concept through commercialization. We offer partial or fully integrated solutions to meet your needs by blending deep subject matter expertise with many years of scientific and project management experience. Our approach is based on understanding your unique needs and challenges, then crafting an integrated development plan to meet them.

      On-Demand Development Team- A Proven, Flexible Model

      Successful integrated drug discovery and development requires a cooperative team of multiple experts from diverse fields. Assembling an expert team for product development can be prohibitively expensive for small companies forced to bring in individual consultants as the needs arise. This approach typically leads to disjointed tasks not aligned with the product strategy, or a development strategy that does not consider the numerous aspects unique to each stage of development. Therefore, many virtual and emerging growth companies are looking for the help and experience only an accomplished consulting group can provide.

      CSSi LifeSciences has a dedicated team ready to help you accelerate your product to commercialization. Our consultative, problem-solving approach is based on first understanding your unique challenges and then crafting a milestone-based and flexible plan to achieve your goals. We utilize a stepwise approach that is appropriate to each phase of product development.
