Use Case

TrialPulse — Disease Burden and Endpoint Selection

Case Study

Listening to the Patient Voice to Understand Disease Burden and Inform Patient-Centric Study Design

Client Goal

Our client was in the process of developing a Phase II Parkinson’s Disease study. In order to support a truly patient-centric study design, the client wished to listen to patients impacted by PD movement disorders in order to: a) understand disease burden, and; b) inform both study endpoint selection and overall design.

Objective 1

Gain a better understanding of the disease burden and unmet needs of Parkinson’s Disease patients and caregivers

Objective 2

Obtain patient feedback and recommendations on the initial design and key study parameters of the proposed Phase 2 clinical study

The inVibe Solution

inVibe’s TrialPulse solution allowed our pharmaceutical client to quickly and efficiently deploy a voice-powered research study to better understand disease burden and unmet needs to inform study design.

1. Collect

Within a few days, inVibe screened and recruited 20 patients (and their loved ones), who were diagnosed with Parkinson’s Disease, and aligned with the inclusion/exclusion criteria of the proposed trial. The participants participated in an automated phone interview on their computers or smart phones, responding to questions by speaking.

Key Questions


Disease Burden


Please take a moment to describe how you experience {a specific symptom of Parkinson's Disease}. What words do you usually use to describe your symptoms? How frequently do they occur? Does anything make your symptoms better or worse?


What does a ‘good day’ living with Parkinson’s Disease look like for you? And what does a ‘bad day’ look like? Please share as much as you like—our goal is to understand what it’s like to walk in your shoes.

Key Questions


Study Design


During the {#} weeks of the clinical trial, you would be asked to make {#} visits to the clinic, each lasting {#} hours, as well as have {#} of check-ins with a doctor over the telephone. What are your overall reactions to these requirements, and how willing would you be to complete these responsibilities?


What do you see as potential downsides or challenges to participating in this trial (if any)? Do you imagine any difficulties with swallowing {#} capsules once every day for {#} weeks?

2. Analyze

inVibe’s analysts leveraged their language expertise and advanced NLP tools to process, evaluate and analyze multiple aspects of each response, including content, language, and emotion derived from speech-emotion recognition, allowing for deeper insights, faster.

What is Said

Summarize and categorize the content and themes.

How it’s Said

Identify the language patterns and construction.

How it Sounds

Utilize machine learning and acoustic technology to assess the emotionality.

3. Deliver

The client was provided with an interactive report via an online dashboard, along with the voice data, transcripts, and a high-level analysis. An in-house analyst walked the client through the most meaningful data, supporting each insight with specific voice data.


Clients have access to drag & drop tools to instantaneously create kinetic text animations from transcripts for internal sharing.

Key Insights & Recommendations

Based on the insights, inVibe recommended that the team take strategic actions:


Patients reported that it was more important to them (their unmet need) that a future treatment addressed {X} aspect of {a specific} Parkinson’s Disease symptom. Thus informing the client’s conceptual model of symptom impact.


Patient Reported Outcomes (PRO) assessments that include not only physical, but also emotional measurements, should be included. Thus informing study design.


Assist patients in definitively assessing whether their participation is feasible by providing robust logistical information about trial location, transportation, and compensation.

Where are they now?

Our client used the research to better understand disease burden, help inform study endpoint selection, and update their conceptual model of symptom impact — ultimately designing a truly patient-centric study.

They will also continue to engage with patients throughtout the clinical development continuum to further validate and finalize the study design, identify participation barriers, design the recruitment plan, validate patient-facing materials, and more.
