Study summary

The goal of this clinical research study is to evaluate the safety and tolerability of injecting certain cells that you produce in your bone marrow called mesenchymal stem cells (MSCs) into your salivary glands.

Participants will have head and neck cancer that was treated with radiation therapy, and in this study will:

  • Undergo a collection of bone marrow using a needle;
  • Donate saliva;
  • Undergo a salivary gland ultrasound; and,
  • Complete questionnaires that ask about dry mouth

Participants can expect to be in this study for up to 30 months.

There is no expanded access program available per this protocol.

Interventions

  • DrugMSC

    Injection of MSCs into submandibular glands at pre-specified dose level: * Dose -1: 5 (4 - 6) x10\^6 MSCs (to be used only if Dose level 1 is not tolerated) per gland (0.5 ml) * Dose 0: 10 (8 - 12) x10\^6 MSCs per gland (1 ml) * Dose 1: 20 (16 - 24) x10\^6 MSCs per gland (2 ml)

What researchers measure

Primary outcomes

  1. Safety and Tolerability: Determination of Recommended Phase 2 Dose (RP2D)

    RP2D (also called the maximum tolerated dose) of MSCs determined by the proportion of subjects experiencing dose limiting toxicity (DLT)

    Time frame: Up to 1 month post-injection

  2. Safety and Tolerability: Number of subjects with pain >5 on a 0-10 point scale

    Incidence of pain assessed as greater than 5 on standard 0-10 point pain scale (0=not at all to 10=worst pain imaginable)

    Time frame: 1 month post-injection

  3. Safety and Tolerability: Number of Serious Adverse Events

    Incidence of any serious adverse event

    Time frame: Up to 1 month post-injection

  4. Safety and Tolerability: Number of Treatment-Emergent Pre-Specified Adverse Events

    Incidence of pre-specified adverse events

    Time frame: Up to 1 month post-injection

Secondary outcomes

  1. Change in Quality of Life

    Efficacy of MSC assessed through University of Michigan Xerostomia Related Quality of Life (XeQOL) scale, which is a 15-item assessment scale with 4 domains. The score is the average of all responses of all domains and can range from 0 to 4, where higher scores indicate increased xerostomia burden.

    Time frame: Baseline to 24 months post-injection

  2. Change in Quality of Life

    Efficacy of MSC assessed through the MD Anderson Dysphagia Index (MDADI), which is a 20-item questionnaire designed for evaluating the impact of dysphagia (swallowing ability). Scores range from 20 (extremely low functioning) to 100 (high functioning).

    Time frame: Baseline to 24 months post-injection

  3. Change in Quality of Life

    Efficacy of MSC assessed through VAS xerostomia questionnaire, which is an 8-item questionnaire that measures the perception of dry mouth. Scores range from 0-10, with 0 being low dryness and 10 being high dryness.

    Time frame: Baseline to 24 months post-injection

  4. Change in salivary production

    Saliva production will be measured by having participants chew inert gum base to the pace of a metronome (70 beats per minute) while expectorating saliva (without swallowing) into the saliva collection aid for 5 minutes total40. Cryovials will be weighed before and after collection and the difference in weight (g) will represent the amount of saliva produced in 5 minutes for each condition.

    Time frame: Baseline to 24 months post-injection

  5. Shear wave velocity with acoustic radiation force impulse

    Assess imaging characteristics of submandibular glands after MSC, measured by ultrasound

    Time frame: 3, 6, and 12 months post-injection
