Insights
The initiation of a Phase 2 investigator-initiated study (IIS) for RELISTOR® in head and neck squamous cell carcinoma patients holds significance in the medical community. The prospective, nonrandomized pilot study aims to assess the drug's efficacy as a potential treatment option. Given that RELISTOR® (methylnaltrexone bromide or MNTX) is primarily known for treating opioid-induced constipation, this repurposing could represent a new revenue stream if proven effective. The primary endpoint focuses on the tolerability of the drug, a critical factor in cancer treatment regimens. Secondary endpoints such as tumor viability and survival rates will provide a holistic view of the drug's impact on the disease. The study's outcomes could potentially lead to a shift in the standard of care for this patient population, pending successful results and subsequent Phase 3 trials.
Head and neck squamous cell carcinoma is a challenging disease with a need for improved treatment options. The use of MNTX in this context is intriguing, as it suggests a novel mechanism of action against cancer cells. The study's design, involving preoperative and postoperative treatment, indicates a potential for MNTX to affect tumor biology and patient recovery. Monitoring patients every 3 months for two years post-study will provide valuable data on long-term outcomes and potential benefits of the drug beyond immediate post-surgical recovery. This could influence future treatment protocols and multidisciplinary approaches in oncology.
Bausch Health Companies Inc.'s support of an IIS can be seen as a strategic move to diversify its product pipeline within its gastroenterology business. Investors should monitor the progress of the RELISTOR® study closely, as positive results could lead to an expansion of the drug's label and market potential. However, the nature of IIS studies, often smaller in scale and preliminary, means that results would need to be replicated in larger, company-sponsored trials to have a substantial impact on the company's valuation. The long-term monitoring aspect of the study suggests a commitment to thorough research, which could enhance the company's reputation in the field, but also implies that any financial benefits would be on a longer horizon.
LAVAL, QC / ACCESSWIRE / March 6, 2024 / Bausch Health Companies Inc. (NYSE:BHC)(TSX:BHC) and its gastroenterology business, Salix Pharmaceuticals, today announced that it is supporting a Phase 2 investigator-initiated study (IIS) of RELISTOR® (methylnaltrexone bromide: MNTX) in patients with resectable head and neck squamous cell carcinoma. An IIS is a study that is proposed, developed, and conducted by a qualified sponsor external to Bausch Health/Salix who assumes full responsibility for the study.
The clinical study is being led by Juan P. Cata, M.D. at The University of Texas MD Anderson Cancer Center. The trial is designed to evaluate the potential of treating oral cavity squamous cell carcinoma patients with MNTX. It is a prospective, nonrandomized pilot "proof of concept" study where patients receive subcutaneous MNTX two weeks preoperatively and two weeks postoperatively.
"The preclinical data and clinical suggestions point to potential activity against cancer," Robert Israel, M.D., Senior Vice President, Clinical and Medical Affairs, said. "Having Dr. Cata study this drug in head and neck cancer will shed light on how and if this agent could be further developed as a potential treatment option in neoplastic disease."
Upon completion of the study, participants will be monitored every 3 months during the first two years. The primary endpoint is the successful administration of MNTX for two weeks preoperatively and postoperatively without interruption due to adverse events. Secondary endpoints include tumor viability, proliferation and apoptosis index, objective response rate, survival rates, and patient-reported outcomes. https://clinicaltrials.gov/ Identifier: NCT06162377.
About RELISTOR
RELISTOR® (methylnaltrexone bromide) is an opioid antagonist. RELISTOR tablets and RELISTOR injection are indicated for the treatment of opioid-induced constipation (OIC) in adults with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g., weekly) opioid dosage escalation.
RELISTOR injection is also indicated for the treatment of OIC in adults with advanced illness or pain caused by active cancer who require opioid dosage escalation for palliative care.
IMPORTANT SAFETY INFORMATION
RELISTOR tablets and injection are contraindicated in patients with known or suspected mechanical gastrointestinal obstruction and patients at increased risk of recurrent obstruction, due to the potential for gastrointestinal perforation.
Cases of gastrointestinal perforation have been reported in adult patients with opioid-induced constipation and advanced illness with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the gastrointestinal tract (e.g., peptic ulcer disease, Ogilvie's syndrome, diverticular disease, infiltrative gastrointestinal tract malignancies or peritoneal metastases). Take into account the overall risk-benefit profile when using RELISTOR in patients with these conditions or other conditions which might result in impaired integrity of the gastrointestinal tract wall (e.g., Crohn's disease). Monitor for the development of severe, persistent, or worsening abdominal pain; discontinue RELISTOR in patients who develop this symptom.
If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their health care provider.
Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, and yawning have occurred in patients treated with RELISTOR. Patients having disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal and/or reduced analgesia and should be monitored for adequacy of analgesia and symptoms of opioid withdrawal.
Avoid concomitant use of RELISTOR with other opioid antagonists because of the potential for additive effects of opioid receptor antagonism and increased risk of opioid withdrawal.
The use of RELISTOR during pregnancy may precipitate opioid withdrawal in a fetus due to the immature fetal blood-brain barrier and should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Because of the potential for serious adverse reactions, including opioid withdrawal, in breastfed infants, advise women that breastfeeding is not recommended during treatment with RELISTOR. In nursing mothers, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
A dosage reduction of RELISTOR tablets and RELISTOR injection is recommended in patients with moderate and severe renal impairment (creatinine clearance less than 60 mL/minute as estimated by Cockcroft-Gault). No dosage adjustment of RELISTOR tablets or RELISTOR injection is needed in patients with mild renal impairment.
A dosage reduction of RELISTOR tablets is recommended in patients with moderate (Child-Pugh Class B) or severe (Child- Pugh Class C) hepatic impairment. No dosage adjustment of RELISTOR tablets is needed in patients with mild hepatic impairment (Child-Pugh Class A). No dosage adjustment of RELISTOR injection is needed for patients with mild or moderate hepatic impairment. In patients with severe hepatic impairment, monitor for methylnaltrexone-related adverse reactions and dose adjust per Prescribing Information as may be indicated.
In the clinical studies, the most common adverse reactions were:
OIC in adult patients with chronic non-cancer pain
RELISTOR tablets (≥
RELISTOR injection (≥
OIC in adult patients with advanced illness
RELISTOR injection (≥
