Brief Summary:
A prospective study for long-term follow-up (LTFU) to evaluate safety and efficacy in subjects who participated in the Phase 1/2 randomized placebo-controlled trial MESRIX.

Condition or disease Intervention/treatment Phase
Radiation Toxicity Xerostomia Due to Radiotherapy Dry Mouth Hyposalivation Mesenchymal Stem Cells Mesenchymal Stromal Cells Long Term Adverse Effects Biological: Autologous adipose-derived mesenchymal stem/stromal cells Other: Placebo Phase 1 Phase 2

Detailed Description:
This is a LTFU study to assess the long-term and late effects of treatment with MSCs or placebo given ultrasound-guided into the submandibular glands in subjects participating in the MESRIX trial. Study participants from the MESRIX trial will be invited for a clinical visit. The visit will include medical history, an ENT examination; measurements of the saliva production by sialometry, a Magnetic resonance imaging scan (MRI) and obtaining data on the patient-reported outcome with Xerostomia Questionnaire (XQ) and Visual-Analogue-Symptomatic scale (VAS). Subjects, who are not able or willing to attend a clinical visit, will be encouraged to fill out the Questionnaires online or on paper. If a study participant has deceased, information of the cause of death will be investigated in The Danish Register of Causes of Death

Primary Outcome Measures :
  1. Safety: Serious Adverse Events (SAEs) and new chronic diseases [ Time Frame: 5 years from randomization ]
    SAEs according to the ICH-GCP definition and new chronic diseases. For patients not attending the planned hospital visit consider searching The National Patient Register will be searched for registered SAEs. Number of patients

  2. Overall survival [ Time Frame: 5 years from randomization ]
    Overall survival is defined as the time from the intraglandular dose of the investigational product (MSCs or placebo) to the date of death or the date the subject is last known to be alive

  3. Relapse of oropharyngeal cancer [ Time Frame: 5 years from randomization ]
    Number of participants with relapse will be reported

  4. New malignancies [ Time Frame: 5 years from randomization ]
    Number of subjects who have new malignancies will be reported

  5. Zoonotic Diseases [ Time Frame: 5 years from randomization ]
    Number of subjects diagnosed Zoonotic Diseases will be reported


Secondary Outcome Measures :
  1. Patient-reported outcome measures-Health-related quality of life (HRQoL [ Time Frame: 5 years from randomization ]
    Xerostomia Questionnaire (XQ) ( Median item scores for each of the 8 questions will be reported (score range 0-10) and the XQ summary/composite score (0-100))
