                                                                             regulatory affairs business process expertise

Downers Grove, IL, February 19th, 2019 – Celegence, a global regulatory affairs services and solution provider, today announced a strategic partnership with Performance Development Group (PDG), a managed learning solution company providing end-to-end learning solutions. The partnership combines Celegence’s regulatory business process expertise with PDG’s learning solution knowledge, delivering clients the skills, quality and commitment to innovation needed to train global users on RIMS (regulatory information management systems).

Celegence’s in-depth knowledge of regulatory business processes and expertise in managing data in RIMS on behalf of clients combined with PDG’s unique tailored learning methodology creates a unique and winning combination. The expertise of both companies was underscored recently when a top-five global pharmaceutical company selected Celegence and PDG to design, develop, and deliver RIMS training to more than 5000 global users.

“Celegence’s expertise in regulatory affairs make them an obvious choice for a partnership with Performance Development Group,” says PDG’s Managing Partner David Manning. “They have a strong and proven record in both solution and business operations expertise, and our capabilities will complement theirs in providing RIMS training.”

Celegence and PDG will work with life sciences companies to help them maximize the ROI of their RIMS investment by ensuring that users are fully prepared to leverage their systems’ benefits. Through the partnership, the companies will also help clients to harmonize the data in their systems so can be leveraged for reporting and analytics. In addition, the global RIMS training program helps clients clarify roles and responsibilities to multiple user communities.

“Celegence and PDG are partnering with the long-term objective to support both mid and large life sciences companies to achieve continuous process improvement for regulatory affairs throughout their global RIMS journey,” says Sonia Veluchamy, CEO of Celegence. “We are confident in our ability to support the industry by combining our subject matter expertise and investment in technology innovations.”

The following is the first in the series of blogs related to the recent updates to EU MDR.

Recent updates to the European Union Medical Device Regulations (MDR) brings about a very important topic for the medical device industry – how to adequately demonstrate equivalence between the device under evaluation and a similar, currently marketed device.

When a medical device Premarket Notification (510k) is filed with the U.S Food and Drug Administration (FDA), the goal is for the agency to determine that the device under evaluation is substantially equivalent to a legally marketed (predicate) device. This substantial equivalence finding conveys that the new device is at least as safe and effective as the predicate device. The new device is then cleared to be legally marketed and is bound to the same classification and regulatory requirements as the predicate device. The message to the public is that the FDA does not have any concerns related to the new device’s safety or effectiveness.

Recently, the CE Marking process for medical devices has incorporated a similar but more strict approach to demonstrating equivalence between medical devices. As you may know, the regulatory submission for a medical device to achieve the CE Mark is a compilation of technical documentation focused on the device under evaluation and does not incorporate a mandatory comparison to any current CE Marked device. It is evaluated as a stand-alone submission. However, a demonstration of equivalence to a medical device with a current CE Mark may be used (optionally) to satisfy one aspect of the regulatory submission – the clinical data requirement. The Revision 4 update to MEDDEV 2.7/1 includes very specific and more strict requirements for a demonstration of equivalence, as compared to the requirements by FDA to support a finding of substantial equivalence.

The below tables summarize the differences in the way the FDA and the European Commission evaluate the clinical, technical and biological characteristics when comparing the device under evaluation and the proposed equivalent device.

For many companies, it is a challenge just to find adequate regulatory resources to compile this exhaustive list of medical device characteristics for both the device under evaluation and the proposed equivalent device. An adequate demonstration of medical device equivalency that meets the requirements of the regulations and passes review by your notified body or the FDA will require a substantial investment of both time and specialized expertise.

Celegence can provide you with subject matter experts, including both regulatory professionals and medical doctors, with relevant device expertise to complete this work for you or to supplement your internal team as needed.

1 The comparison is risk-based and there is flexibility in a finding of “similarity”. When changes between the indications for use raise a new safety or effectiveness issue or have the potential to significantly increase a safety or effectiveness concern, equivalence is not supported.
2 The flexibility in differences of materials or biological contact profile is dependent on FDA’s conclusions on what constitutes a significant difference to safety or effectiveness, based off industry meta-data (all relevant pre-market and post-market data).


A global top 5 pharmaceutical company was looking to evaluate an IDMP solution including core application functionalities, complexities involved in current data readiness, source systems and business processes for data collection and processing.


The organization wanted to leverage the data in existing systems for IDMP compliance and maximize usage of the current functional systems through harmonized business processes.

Celegence was awarded a contract to help the customer with the business process related activities, including process definition & evaluation of the following activities:

  • Data Gathering
  • Submission Management
  • End-to-End Operational Data Management
  • Definition and evaluation of business strategy based on PoC findings
  • Validation & Compliance Analysis from business process perspective

While the technology vendor was responsible for the system implementation and integrations, Celegence managed and will continue to manage the IDMP data services for each iteration as they are defined going forward:
