Clinical Trial Summary

This proposed pilot study will investigate the safety and initial effectiveness of focused ultrasound lesioning of the contralateral mesencephalon for severe, opioid-resistant pain associated with head and neck cancer

Description:

This pilot study is designed as a prospective, open-label clinical trial of stereotactic FUS mesencephalotomy in 6 subjects with treatment-refractory pain from head and neck cancer. Primary safety assessments will be made throughout the study period of 6 months following the procedure. Primary efficacy outcome is determined by comparing the difference in baseline NPRS to 3 months post treatment. All subjects receiving treatment will be followed for the six month study period.

• Est. primary completion date: August 31, 2024
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 75 Years

Eligibility

Inclusion Criteria:

1. Men and women, between 18 and 75 years, inclusive

2. Subjects with head and neck cancer, including one of the following:

• Cancer that arises in the head and neck region: nasal cavity, sinuses, lips, mouth, salivary glands, throat, or larynx (typically squamous cell carcinoma)
• Cancer occurring in the nasopharynx, skin, thyroid gland, and eye
• Lymphoma
• Sarcoma

3. Craniofacial or cervical pain related to the cancer that meets all of the following

criteria:

• Severe defined by: Worst NPRS score of = 5 out of 10 at current visit and the subject reports having a similar level of pain for at least the past two months.
• Pain is medication-refractory to all three tiers of the WHO cancer pain ladder. Thus, adequate trials of at least 3 prescription medications that will include a 'weak' and a 'strong' opioid. An adequate medication trial is defined as a therapeutic dose of each medication without sufficient effect.
• Duration of greater than 6 months

4. Mesencephalon contralateral to the pain can be targeted by the ExAblate Neuro device. The region of the mesencephalon must be apparent on MRI. Additional MRI sequences including inversion-recovery and DTI may be utilized to refine the target.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Adverse Events	Number of participants with treatment-related adverse events, as assessed from adverse event reporting throughout the 6 month study period. Additional measures of safety will be made with MRI evaluation.	6 months post-intervention
Primary	Numeric Pain Rating Scale	Will compare the change of WORST pain experienced in 24 hours before (baseline) and at 3 months following unilateral FUS mesencephalotomy as determined from the 11-point numeric pain rating scale (0-10), with 0 being no pain and 10 being the worst pain imaginable.	3 months post-intervention (will also be assessed at 7 days, 1 month, and 6 months post-intervention)
Secondary	Patient Global Impression of Change	Change from baseline scores to post-intervention time points (see below), as measured by a patient questionnaire that asks patients to describe the change (if any) compared to their condition prior to treatment in activity, limitations, symptoms, emotions, and overall quality of life, related to their painful condition. The options include no change, almost the same, a little better, somewhat better, moderately better, better, and a great deal better.	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS scale v1.0 - Pain Intensity 3a	Change from baseline scores to post-intervention time points (see below). The first two items in the Pain Intensity item bank assess pain intensity utilizing a 7-day recall period (items include the phrase "the past 7 days") while the last item asks patient to rate their pain intensity "right now." The Pain Intensity instrument is available for adults (ages 18+). Scale includes range from 1-5, with 1 = "Had no pain" and 5 = "Very severe".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS scale v2.0 - Neuropathic Pain Quality 5a	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that asks about pain quality in the past 7 days, specifically asking if the pain has felt like pins and needles, tingly, stinging, electrical, or numb, on a scale from 1-5, with 1 = "Not at all" and 5 = "Very much".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS scale v2.0 - Nociceptive Pain Quality 5a	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that asks about pain quality in the past 7 days, specifically asking if the pain has felt sore, tender, achy, deep, or steady, on a scale from 1-5, with 1 = "Not at all" and 5 = "Very much".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS scale v1.0 - Pain Behavior 7a	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures self-reported external manifestations of pain in the past 7 days, including actions and reactions that can be either verbal or nonverbal, and involuntary or deliberate. Measured on a scale from 1-6, with 1 = "Had no pain" and 6 = "Always".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS scale v1.0 - Pain Interference 8a	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures self-reported consequences of pain on relevant aspects of one's life in the past 7 days. Includes the extent to which pain hinders engagement with social, cognitive, emotional, physical, and recreational activities. Also incorporates items probing sleep and enjoyment in life. Measured on scale from 1-5, with 1 = "Not at all" and 5 = "Very much".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS - Ca Item Bank v1.0 - Emotional Distress-Anxiety	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures self-reported fear (fearfulness, panic), anxious misery (worry, dread), hyperarousal (tension, nervousness, restlessness), and somatic symptoms related to arousal (racing heart, dizziness), in the past 7 days. Measured on scale from 1-5, with 1 = "Never" and 5 = "Always".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS - Ca Item Bank v1.0 - Emotional Distress-Depression	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures self-reported negative mood (sadness, guilt), views of self (self-criticism, worthlessness), and social cognition (loneliness, interpersonal alienation), as well as decreased positive affect and engagement (loss of interest, meaning, and purpose), in the past 7 days. Somatic symptoms (changes in appetite, sleeping patterns) are not included, which eliminates consideration of these items' confounding effects when assessing patients with comorbid physical conditions. Measured on a scale from 1-5, with 1 = "Never" and 5 = "Always".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS - Ca Item Bank v1.0 - Fatigue	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures a range of self-reported symptoms, from mild subjective feelings of tiredness to an overwhelming, debilitating, and sustained sense of exhaustion that likely decreases one's ability to execute daily activities and function normally in family or social roles. Fatigue is divided into the experience of fatigue (frequency, duration, and intensity) and the impact of fatigue on physical, mental, and social activities. The Fatigue short form is universal rather than disease-specific. It assesses fatigue over the past seven days. Measured on a scale from 1-5, with 1 = "Never" and 5 = "Always".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	PROMIS - Ca Bank v1.1 - Physical Function	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that measures self-reported capability rather than actual performance of physical activities. Measured on a scale from 5 to 1, with 5 = "Without any difficulty" and 1 = "Unable to do".	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	Pain Catastrophizing Scale	Change from baseline scores to post-intervention time points (see below), as assessed by patient questionnaire that asks participants to reflect on past painful experiences, and to indicate the degree to which they experienced each of 13 thoughts or feelings when experiencing pain, on 5-point scales with the end points (0) not at all and (4) all the time.	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	Daily morphine equivalents (milligrams)	Change of the amount of morphine that is used by patient daily, in daily morphine equivalents (in milligrams), from baseline through 6 months post-intervention.	Baseline, 7 days, 1 month, 3 months, and 6 months post-intervention
Secondary	Location of lesion in the x, y, z dimensions in mm	The location of the lesion will be measured in the x, y, and z dimensions, and will be reported in mm.	7 days and 3 months post-intervention
Secondary	Precision of lesion in the x, y, z dimensions and two dimensional radial vector in mm	The precision of the lesion will be measured in the x, y, and z dimensions, but also in a two dimensional radial vector, all reported in mm.	7 days and 3 months post-intervention
Secondary	Volume of lesion in mm3	The volume of the lesion will be measured in mm3.	7 days and 3 months post-intervention
