Optimize clinical trial performance and efficiency


Most sites use their CTMS to manage their portfolio of trials and create a protocol calendar based on each protocol document. This typically takes 8-20 hour per site, an effort replicated anywhere from 10 to 100 times per study. With protocols becoming increasingly complex, this isn’t just extremely inefficient, but poses a risk to patient safety.

Rather than duplicating this effort, sites can use Nimblify Protocol Calendars (previously known as the Calendar Exchange) for centrally pre-built calendars released through integration with their CTMS.

  • Downloads immediately into your CTMS
  • Generates subject-specific schedules to identify deviations and out-of-window study visits
  • Ensures each patient gets his or her planned care and procedures at the right time

Why use Nimblify Protocol Calendars?

Learn why 100% of our customers would recommend Nimblify Calendars to other organizations in the industry.

Get time back

Without the bandwidth to take on calendar creation, many sites end up with a backlog of protocols that need to be built. Nimblify Protocol Calendars helps sites boost productivity and reassign resources.

Integrates with your CTMS

Calendars import into the site CTMS, pulling in all treatment arms immediately. Sites can use the same calendar as the source of truth for downstream activities – from subject visit tracking to budgeting.

Fast turnaround time

With a 100% satisfaction rate on turnaround time by our customers for the 4,397 unique calendars we’ve built so far, using Nimblify Protocol Calendars is much faster than building internally.

Ensure accuracy

Sites don’t have to rely on staff to make judgment calls on the protocol independently, eliminating confusion and misinterpretation while increasing protocol compliance and minimizing deviations.

How to get started with Nimblify Calendars

  1. Fill out this form to get started.
  2. Get your pre-integrated CTMS (OnCore or Allegro) connected.
  3. Send Nimblify your protocol.
  4. If the protocol calendar is already built, Nimblify will make it available for download. If not, Nimblify builds it within three to seven business days.
  5. Receive the calendar build notes from Nimblify and access the calendar in your CTMS, or receive the spreadsheet representation of the protocol calendar via email.

Dave Mulvihill, IT Project Manager
Washington University School of Medicine

“We worked with the Calendar Team for a period of nine months to build out over 600 study calendars. Providing clear guidelines for how details from protocol documents would be extracted, interpreted and applied toward the creation of calendars allowed us to enjoy extremely fast turnaround times. As such, local study teams’ review cycles were expedited which ultimately led to shortened activation timelines. Working with the Calendar Team always felt like a collaborative effort and never like a vendor just providing services.”

Magdalene Lindenbaum, Project Manager, Clinical Trials Administration Office

“The Calendar Team is very good at picking up visits in complicated cancer studies where visits are not in one straight flow.”

Paul Park, Manager, Clinical Research Systems
Thomas Jefferson University

“We absolutely appreciate the turnaround time and quality of builds. The Calendar Team’s quick suggestions on Treatment Arm Setup is very helpful.”

Martin Braun, Budget Specialist
UVA Cancer Center

“I would recommend this service as it was an efficient and beneficial way to have calendars made for the OnCore system. The turnaround time is minimal and calendars are essential for patient data and financials to be entered into the system.”

Michelle Medeiros, Clinical Research Manager
University of Maryland Greenebaum Cancer Center

“Using the Protocol Calendar Exchange has been money well spent. The Build Team has been very responsive, efficient and extremely helpful. The turnaround times are great and often sooner than expected. We also really enjoy build documents –they are carefully drafted, outlining each element on the calendar with the reasoning behind it.”

Seth Luty, Clinical Research Analyst II
Yale University

“The build summary (notes) have been very helpful. The overall quality has been very good.”

Is my CTMS integrated?

For a direct calendar download into a CTMS, OnCore and Allegro from Forte Research Systems are currently available. If you use a different system, please encourage your CTMS vendor to contact us if they’re interested in interfacing.

Who has access to calendar information?

As part of the calendar build process, you will share protocol documents with the Nimblify Calendar Build team. We take precautions to ensure confidentiality of any information shared with Nimblify. Your documents are not shared beyond the Nimblify team involved in your calendar build. Calendar builds are available only to sites that are participating in the protocol. In the instance that the calendar you are requesting has already been built, we still require that you provide us a copy of the protocol documents to demonstrate that you have authorized access to the protocol details.

What types of calendars can I order?

There are no restrictions on the types of calendars that you can request. This includes all disciplines supported by OnCore and Allegro, such as oncology, cardiology, and psychiatry. Nimblify will build each calendar according to a set of guidelines. Once a calendar is imported, you can make organization-specific changes.
