Ketamine-assisted Therapy for Patients With Pancreatic Ductal Adenocarcinoma
This clinical trial evaluates whether it is possible to use a single dose of oral liquid ketamine (ingested by mouth) in combination with talk therapy to treat moderate to severe demoralization in patients with pancreatic ductal adenocarcinoma (PDAC) who take opioids for cancer-related pain. PDAC patients often suffer from high rates of psychosocial distress and pain. Symptoms of anxiety are highly prevalent among PDAC patients. While opioid analgesia (pain reliever) succeeds in managing some symptoms, chronic opioid therapy is associated with significant adverse effects, underscoring a need to identify alternative interventions in the treatment of PDAC-associated pain. PDAC patients frequently suffer from existential distress. Demoralization is a form of existential distress that is common among people with serious medical illnesses; it is characterized by poor coping with stressful events, and a loss of meaning and purpose in life. Talk therapy is a form of psychological treatment during which patients discuss problems, thoughts, and feelings. Ketamine has demonstrated efficacy for the treatment of depression, suicidality, and pain in non-cancer patients. This study may help researchers learn whether both ketamine and talk therapy may improve psychosocial distress and pain, as well as decreases in opioid analgesic use in patients with PDAC who take opioids for cancer-related pain.
Pilot Study of Ketamine-assisted Talk Therapy for Demoralization in Patients With Pancreatic Ductal Adenocarcinoma and Pain
- To assess the feasibility of Meaning and Purpose therapy combined with oral ketamine (K-MaP) in demoralized patients.
- To characterize the preliminary safety and tolerability of K-MaP in demoralized patients with pancreatic ductal adenocarcinoma.
II. To assess the magnitude and durability of improvement from randomization in psychosocial distress.
III. To assess the magnitude and durability of improvement from randomization in pain.
IV. To assess the magnitude of change from randomization in opioid analgesic use.
- To assess how the participant's subjective experiences with ketamine may be related to clinical outcomes.
II. To assess how participants' stage of PDAC may be related to clinical outcomes.
Adult pancreatic ductal adenocarcinoma (PDAC) participants receiving care at the Helen Diller Family Comprehensive Cancer Center (HDFCCC) will be randomized in a 1:1 ratio to one of two blinded dose cohorts consisting of a single drug treatment and several therapy sessions, for up to 7 weeks. Participants will be followed up to 35 days (+/-2 days) after ketamine administration.

- Must be able to swallow liquid oral medication.
- Clinically significant demoralization as assessed by the Demoralization Scale-II (DS-II).
- Must have used any opioid-based analgesia for cancer-related pain in the last 7 days (at time of screening).
- Must discontinue the following medications and refrain from taking them for the duration of study participation (participants who require these medications will be taken off study):
- as-needed (PRN) anxiolytics. Note: Benzodiazepine use may be allowed if used in a regular, scheduled way. Consultation with the Principal Investigator is recommended.
- Dopamine agonists
- Female-born participants of child-bearing potential with male-born partners must use highly effective contraception for at least 1 month prior to ketamine administration (on day 0) and agree to use such a method for an additional 2 months after ketamine administration.
- Male-born participants with female-born partners of child-bearing potential must use highly effective contraception for at least 1 month prior to ketamine administration and agree to use such a method for an additional 2 months after ketamine administration. Note: Highly effective contraception include:
- Intrauterine device (IUD)
- Intrauterine hormone-releasing system (IUS)
- Non-oral hormonal methods, including injected, intravaginal, implanted, transdermal
- Oral hormones plus a barrier contraception (condom, diaphragm, or spermicide)
- Double barrier method (at least two of the following: condom, diaphragm, and spermicide)
- Abstinence from penile-vaginal intercourse* *The reliability of abstinence should be evaluated carefully with the participant in relation to their general lifestyle. An additional acceptable birth control method should be discussed with the participant in case participants decide to engage in penile-vaginal intercourse during the course of the study.
- Must agree to the following life-style considerations:
- Continue receiving psychotherapy or other behavioral interventions for mental health as usual. Current interventions should not be stopped and new interventions should not be started during the study period once participants are enrolled in the study.
- Consume no more than a modest quantity (e.g., 1 cup) of caffeine or xanthine-containing products (e.g., coffee or tea) the morning of receiving ketamine (on Day 0/Visit 4).
- Abstain from alcohol for 24 hours before receiving ketamine.
- Abstain from using any nicotine-containing products (including nicotine patches) for 3 hours before receiving ketamine.
- If cannabis products are used regularly, participants will be asked to continue using regular amount, but will be asked not to use cannabis within 24 hours prior to receiving ketamine.
- If prescribed a regular dose of benzodiazepines, participants will be asked not to take medication the morning of the ketamine administration visit.
- If taking any psychostimulants (e.g., methylphenidate), participants will be asked not to take psychostimulant drugs (other than caffeine) the morning of the ketamine administration visit.
- Participants will be advised to maintain usual opioid regimen. Note: Input will be obtained from the participant's regular clinical providers on appropriate pain management for the participant during the study, particularly in the case of analgesics associated with adverse reactions of concern with ketamine (e.g., tramadol and any opioid may increase risk of respiratory depression from ketamine).
