New publication shows effectiveness data for weekly and monthly buprenorphine injections in treating opioid dependence in individuals using fentanyl
- Study Findings: A post hoc analysis published in JAMA Network Open shows the effectiveness of weekly and monthly subcutaneous buprenorphine injections compared to daily sublingual buprenorphine/naloxone in treating opioid dependence, particularly among fentanyl users.
- Research Results: The study involved 428 participants, with 123 using fentanyl at baseline. Those on subcutaneous buprenorphine had higher rates of negative fentanyl urine samples during the study compared to those on sublingual buprenorphine/naloxone.
- Impact on Withdrawal Symptoms: Patients using fentanyl at baseline experienced reduced withdrawal symptoms and cravings after treatment initiation with extended-release buprenorphine.
- Safety Profile: The safety profile of subcutaneous buprenorphine was similar to known profiles of buprenorphine, except for mild to moderate injection site reactions.
- Availability and Use: Buvidal, the prolonged-release buprenorphine solution, is indicated for opioid dependence treatment in adults and adolescents, with different strengths available for tailored treatment.

CAM2056 Efficacy: CAM2056 demonstrated a 9.3% weight reduction and significant A1c improvements, comparable to or exceeding the results of weekly semaglutide (Wegovy®), with a notable treatment difference of -4.1% in weight loss by Day 85.
Safety and Tolerability: The safety profile of CAM2056 was favorable, with mild to moderate gastrointestinal adverse events being the most common, and overall tolerability consistent with that of weekly semaglutide, despite higher initial doses.
Dosing Convenience: CAM2056 allows for monthly dosing with rapid initiation through biweekly doses, potentially improving patient adherence compared to weekly semaglutide.
Future Studies: Camurus plans to conduct a Phase 2b trial in 2026 to further evaluate CAM2056, focusing on longer treatment durations and higher doses.
Approval Announcement: Camurus has received marketing authorization from the UK Medicines and Healthcare products Regulatory Agency (MHRA) for Oczyesa®, a once-monthly subcutaneous octreotide treatment for adult patients with acromegaly.
Clinical Efficacy: The approval is based on results from a comprehensive clinical program, including two Phase 3 studies, demonstrating effective control of acromegaly and improved patient quality of life.
Self-Administration Feature: Oczyesa® can be self-administered using a pre-filled autoinjector pen, making it convenient for patients to manage their treatment at home.
Future Developments: Camurus plans to launch Oczyesa® in the UK in the fourth quarter of 2025 and is also developing CAM2029 for other severe diseases, including gastroenteropancreatic neuroendocrine tumors and polycystic liver disease.

New Treatment Approval: The European Commission has granted marketing authorization for Oczyesa®, a once-monthly subcutaneous octreotide treatment for adults with acromegaly who have previously responded to somatostatin analogs, marking it as the first of its kind for this condition.
Clinical Benefits: Clinical trials indicate that Oczyesa® provides effective disease control, improves symptoms and quality of life, and allows for convenient self-administration using a pre-filled autoinjector pen.

CAM2029 Study Results: The Phase 2b POSITANO study demonstrated that CAM2029 significantly reduces liver and cyst volume in patients with symptomatic polycystic liver disease (PLD) compared to placebo, while also improving symptoms.
Safety and Future Plans: CAM2029 was well tolerated with no new safety concerns, and Camurus plans to discuss a follow-up Phase 3 study with regulatory authorities in the US and Europe.
Collaboration Agreement: Eli Lilly & Co. has partnered with Swedish company Camurus to develop long-acting obesity treatments, valued at $870 million, utilizing Camurus’ drug delivery technology to enhance weight-loss medications like Zepbound.
Market Outlook: The collaboration aims to meet the growing demand for obesity medications by potentially offering less frequent dosing schedules, while Eli Lilly's stock holds a Strong Buy recommendation from analysts, indicating positive market sentiment.

Collaboration Agreement: Camurus and Eli Lilly have formed a partnership to develop long-acting incretin therapies for cardiometabolic health using Camurus' FluidCrystal technology, with potential payments totaling up to $870 million for Camurus.
FluidCrystal Technology: This proprietary technology allows for the extended release of drugs through a single injection, transforming into a gel upon contact with bodily fluids, and is already validated by market approvals in multiple regions.
