Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

This is a multi-site (4 US sites) observational open-label diagnostic study of a non-significant risk medical device, PointCheckTM. Participants (N=210) with specific malignancies who are scheduled to receive antineoplastic therapy will be evaluated during their routine management before the planned cytotoxic drug administration at two-time points (baseline and nadir evaluation). This will be an event-driven study with a total number of 70 positive cases (ANC < 500 cells/mm3) and 140 negative cases (ANC >= 500 cells/mm3) has been considered sufficient to provide accurate estimates of Sensitivity and Specificity. They will have concurrent evaluations with PointCheckTM and a blood differential cell count in addition to the standard clinical visits. A subset (N=45) of patients will be evaluated for between-instrument reproducibility. Finally, a sub-study (N=30) will confirm the usability of PointCheckTM in the home setting.

Description

Inclusion Criteria:

  • Able to understand the purpose and risks of the study and to provide signed and dated informed consent and authorization to use confidential health information in accordance with national and local subject privacy regulations.
  • Male or Female aged 10 years or above.
  • Diagnosed with either Diffuse Large B Cell Lymphoma or Multiple Myeloma.
  • Scheduled treatment with any antineoplastic therapy with an associated high/intermediate risk of neutropenia according to NCCN guidelines.
  • Able (in the investigator's opinion) and willing to comply with all study requirements.

Exclusion Criteria:

  • Participants with amputations, congenital malformations or any severe abnormalities of the hands as determined by the investigator.
  • Participants with a history of vasculitis, Raynaud syndrome, scleroderma, mixed connective tissue disease or any other rheumatologic systemic condition that could produce microcirculatory changes in the nailfold.
  • Participants with circulating tumour cells in previous or current lab determinations.
  • Participants with any condition producing significant tremor (e.g., essential tremor, Parkinson´s disease, dystonic tremor).
  • Unstable participants or participants with hypotension (systolic blood pressure <90 and diastolic blood pressure < 60mmHg).
  • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
  • Other unspecified reasons that, in the opinion of the Investigator or Sponsor, make the subject unsuitable for enrolment.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PointCheck Accuracy
Time Frame: Two weeks
The main primary endpoints for this study will be the sensitivity and specificity of PointCheckTM to detect grade IV neutropenia ac cording to the CTCAE V5 definition of severe neutropenia in a standard blood analysis.
Two weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
