A Study of Methylnaltrexone Bromide (MNTX) in Participants With Advanced Pancreatic Cancer

May 5, 2021 updated by: Bausch Health Americas, Inc.

A Phase II/III Adaptive Study to Evaluate the Safety and Efficacy of Oral Methylnaltrexone Bromide Tablets in Subjects With Advanced Pancreatic Cancer

This is an adaptive design study. During the first phase of the study, participants will be randomized in 2:1 ratio to receive either MNTX 450 milligrams (mg) once daily (QD) or placebo. An interim analysis will be performed for futility and at that point a higher dosage regimen may be utilized for the active treatment group if the futility criteria are met. For the second stage of the study, interim analyses will be conducted for futility and sample size reassessment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Refused standard chemotherapy, or failed at least one standard of care chemotherapy regimen for pancreatic cancer and refused additional chemotherapy.
  • Must be on stable dose of opioids within 2 weeks prior to randomization.
  • At least 18 years of age on the date the Informed Consent Form (ICF) is signed and with the capacity to provide voluntary informed consent.
  • Must be able to read, understand and provide written informed consent on the Institutional Review Board (IRB)/Ethics Committee (EC) approved ICF and provide authorization as appropriate for local privacy regulations.
  • Had no radiotherapy, chemotherapy, or immunotherapy within the 14 days prior to randomization.
  • Has no continuing toxicity or potential of delayed toxicity from any prior antineoplastic therapy that can be reasonably anticipated, in the opinion of the principal investigator.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0,1, or 2.
  • Life expectancy of at least 3 months from date of informed consent.
  • Baseline laboratory results as follows: Absolute neutrophil count (ANC) greater than or equal to (≥) 1.0 * 10^9/liter; Platelets ≥50 * 10^9/liter (without platelet transfusion); Bilirubin less than or equal to (≤) 1.5 * upper limit of normal (ULN); Aspartate aminotransferase (AST) ≤5 * ULN; Alanine aminotransferase (ALT) ≤5 * ULN; Negative serum or urine pregnancy test for females of childbearing potential (premenopausal female capable of becoming pregnant).
  • Signed an informed consent/Health Insurance Portability and Accountability Act (HIPAA) form.
  • Willing and able to comply with scheduled visits, the treatment plan, and laboratory tests.

Exclusion Criteria:

  • Concurrent therapy with any other investigational or non-investigational anticancer agent within 14 days of the baseline visit.
  • Radiation therapy except for palliative care on a non-target lesion.
  • Current use of a peripherally Acting mu-opioid receptor antagonist.
  • Be a pregnant or breast-feeding woman.
  • Female participants of childbearing potential must agree to use effective contraception method, except if she is of non-childbearing potential, defined as surgically sterile (that is; has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation at least 3 months earlier) or in a menopausal state (at least 1 year without menses). Male participants must agree to use effective contraception or be surgically sterile (vasectomized for greater than 6 months).
  • Have dementia or altered mental status that would prohibit informed consent.
  • Diarrhea ≥Grade 1 (Common Terminology Criteria Version 5.0 [CTC V5.0]).

  • Moderate or severe renal impairment (that is; creatinine clearance less than 60 milliliters/minute as estimated by Cockcroft Gault)
  • Have any other unstable medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the Principal Investigator, would make the participant inappropriate for the study.

Experimental: Methylnaltrexone Bromide (MNTX)
Participants will receive methylnaltrexone bromide (MNTX) 450 mg (3 tablets of 150 mg each) QD orally. If the initial interim analysis suggests a lack of efficacy, subsequent participants will receive 450 mg MNTX twice daily (BID) or three times daily (TID). Treatment will continue until participant's death or early withdrawal from study or study completion at Day 168.

Methylnaltrexone bromide will be administered per dose and schedule specified in the respective arm.
Other Names:
  • Relistor®
Placebo Comparator: Placebo

Drug: Placebo
Placebo matching to methylnaltrexone bromide will be administered as mentioned in the respective arm.
