The mYXpression RHEUMATOID test

mYboX kit and blood sample

Click to toggle

To determine the suitable biotherapy, it is necessary to collect a few drops of the patient’s blood to sequence their RNA. This procedure is crucial to target the right treatment.

So that the patient can carry out this simple procedure, a kit named mYboX (with the elements to carry out the self-sample) is sent to them once the order has been confirmed.

Click to toggle

mYboX contains all the elements required to perform the self blood test in total

  • An explanatory leaflet will guide the patient step by step through the self blood test process
  • A glove
  • 1 dressing
  • 1 alcohol swab
  • 2 lancets
  • 1 blood drop pack
  • Three envelopes (one with a zip, one with bubble-wrap and one for UPS shipping) in which the patient will slide the blood drop pack to send it in total safety to our genomics platform.

How is my mYboX delivered?

We will deliver it by UPS. UPS is a major parcel delivery company, known for its traceability, the large number of collection points, and the safety of parcel transportation.

As soon as mYboX leaves our logistics platform, the patient will be notified by e-mail. 

If the patient has opted for home delivery, no action will be required by them. mYboX will be delivered directly to the address indicated at the time of order.

If the patient has opted for a collection point, they will be informed by e-mail of when the mYboX has been left at the collection point selected when the order was made.

How do take the blood sample?

To take the blood sample, the patient should refer to the explanatory leaflet in the mYboX. This will guide the patient step-by-step to ensure the blood sample is taken correctly.

Please inform us via " Nor contact "

How do I return the blood sample?

Once the sample has been taken, the patient must leave the UPS envelope containing their blood sample at the collection point of their choice.

Click to toggle

Once you have received your mYboX kit , you have a period of 5 days to send back your blood sample.

Is patient notified that their blood sample has arrived at the genomics platform?

Yes, an e-mail is sent to confirm receipt of the blood sample at our genomics platform.

What happens to the blood sample?

Our genomics platform takes the blood sample when the parcel arrives. The lab technicians then remove the drops of blood from the pack. The RNA sequencing is then carried out to determine the " personal multi-genomics signature" of the patient. Once all of these steps have been completed, the patient’s blood sample is destroyed.

Customised treatment report: RITI®

Click to toggle

mYXpression RHEUMATOID offers a tool to help select the best biotherapy, based on the biological profile of a patient with rheumatoid arthritis. 

Thanks to RITI®, the rheumatologist will have all the scientific information concerning their patient. 

The doctor may then prescribe, with total objectivity and confidence, the biotherapy most suited to the patient, and that will be the most effective. 

Who is the mYXpression rheumatoid test for?

It is for any patient whose doctor has diagnosed rheumatoid arthritis, and is planning OR has already prescribed a biotherapy.

2 figures:

1.    1st initial prescription by the doctor: the patient has never taken biotherapy

2.    The patient has already been treated using a biotherapy, but:

  • the symptoms did not improve: this is primary failure
  • the symptoms of the disease decreased then rapidly worsened: this is secondary treatment failure.

How long will it take to receive my personal RITI® report?

Upon receipt of the blood sample from the patient at our genomics platform, it will take a maximum of six weeks to carry out all the complex procedures to produce the personal RITI®report.

Click to toggle

As soon as the RITI® report has been produced by our powerful computers, the patient will receive an e-mail inviting them to log on to their personal mYXpression rheumatoid space to download their RITI® report.

The patient can print out the RITI® report and send it to their rheumatologist.

How can the patient access the RITI® report?

The patient can access their RITI® report via their personal space on mYXpression rheumatoid.

To do so, the patient must visit, to log in to their personal space with their connection details and click on " History and details of orders/results ".

How does the patient send their RITI® to their rheumatologist?

To send RITI® to their doctor, the patient should download the report via their personal space, and print it out and hand it personally to their doctor. 

This latter is the only person competent to interpret the comprehensive scientific data in the RITI® report and to decide whether or not to prescribe the biotherapy recommended in the RITI®report.

Access to your RITI® report is strictly personal.

The patient can access it using their personal login details for the mYXpression rheumatoidplatform.

Precision medicine is based on the following principle: "The right treatment, at the right time, for the right patient."

This medical approach entails studying the biological profile of an individual to prescribe a targeted, suitable treatment.

However, the implementation of precision medicine is extremely complex and requires significant cutting-edge resources.

Taking into account individual genetic variability, the environment and the lifestyle of each individual, personalised medicine offers tremendous prospects for improving the therapeutic journey for a patient.

Biotherapy refers to a new generation of drugs that act precisely on the mechanisms of inflammation.

Biotherapy is a targeted therapy used as a disease-modifying treatment offered by a rheumatologist depending on the development of the rheumatoid arthritis.

To date, there are about a dozen biotherapies grouped into five therapeutic classes to treat rheumatoid arthritis.

The most used class is the anti-TNF-alpha class and others are now part of the therapeutic arsenal.

To optimise the efficacy of these revolutionary treatments for your pathology, we target the biotherapy that is the most suited to your biological profile.

The fate of symptoms and the development of your disease depend on the choice of treatment.

Indeed, the more closely matched the prescribed biotherapy is to your immunological deregulation, the greater the chances of remission.

RNA is a molecule consisting of the expression of some genes of your DNA.

There are several types RNA, but the one that holds your biological information that we sequence is your messenger RNA.

Think of the messenger RNA as "a recipe " that is very specific and short-lasting.

" This recipe " produces large number of pro-inflammatory cells that are responsible for your symptoms.

Your messenger RNA is, therefore, a very specific and unique biological indicator of the mechanisms in action related to your pathology.

When sequencing, we will quantify the "ingredients " used by your body to make these pro-inflammatory cells.

Your blood sample sequenced by mYXpression contains your unique" personal multi-genomic signature" that will be compared to our huge database on rheumatoid arthritis.

Data processing

The genomics platform that sequences your messenger RNA has existed for twenty years.

Role of mYXpression

Click to toggle

mYXpression can under no circumstances produce a diagnosis. mYXpression has no intention to take the place of your doctor and nothing can replace a clinical examination and direct dialogue.

If you notice the signs and symptoms associated with this pathology, please contact a rheumatologist, who, after a series of tests, will be able to produce a precise diagnosis.

Can mYXpression prescribe a biotherapy?

mYXpression offers a tool to help identify the best biotherapy based on your biological profile.

mYXpression cannot prescribe a biotherapy. Your rheumatologist alone chooses whether or not to prescribe the biotherapy based on the scientific and medical information available to them.
