"We are pleased that the review procedure has been initiated. There is a high unmet medical need in chronic pain, particularly among patients with concomitant opioid use problems. If approved, Buvidal could become an important therapeutic option for the management of chronic pain, adding to the current indication of treating opioid dependence", says Dr.
Chronic pain is estimated to affect over 20% of the European population1,2, with an even higher prevalence rate of 33-55% amongst patients diagnosed with opioid dependence.3,4 Management of the condition is today regarded as one of the most difficult clinical challenges.5,6 Opioids have for long been used in the treatment of chronic pain for achieving and maintaining an optimal level of pain control. However, long-term opioid therapy is associated with increased risks of developing dependence and misuse.5,7
The regulatory submission is supported by results from a Phase 2 study of Buvidal (CAM2038) in patients with chronic non-cancer pain and opioid dependence, and a Phase 3 efficacy and safety study of CAM2038 in patients with moderate to severe chronic low back pain treated with opioid pain medications for a minimum of 3 months prior to study enrollment. The Phase 3 study also comprised an open-label extension phase over 52 weeks, assessing long-term efficacy and safety in roll-over patients from the randomized part of the study and new patients with different categories of moderate to severe, chronic non-cancer pain. Both primary and secondary endpoints were met in the randomized part of the study, demonstrating significantly lower average and worst pain scores for patients treated with CAM2038 compared to placebo at the end of the randomized treatment period compared to baseline. The safety profile was consistent with both the well-known profile of buprenorphine, and with the safety profile of Buvidal in opioid dependent patients.
A regulatory approval decision is expected in the second half of 2022.

About Buvidal
Buvidal® (buprenorphine prolonged-release solution for subcutaneous injection in prefilled syringe) is indicated for the treatment of opioid dependence within a framework of medical, social, and psychological treatment.8 Treatment is intended for use in adults and adolescents aged 16 years or over. Buvidal is designed for flexible dosing and is available in four weekly strengths (8mg, 16mg, 24mg and 32mg) and four monthly strengths (64mg, 96mg, 128mg and 160mg), enabling treatment to be tailored to the patient's individual needs.
About chronic pain
The most recent classifications define chronic pain as any somatic pain lasting longer than three months.9,10 Chronic pain has a high prevalence, affecting over 20% of the European population.1,2 It is one of the most frequent reasons to seek medical care.11 Chronic pain management is one of the most difficult clinical challenges in medicine today with a high and unmet medical need and requires a multimodal, interdisciplinary treatment approach.5,6 In chronic pain, opioid therapy can be a useful tool in achieving and maintaining an optimal level of pain control.7 However, long-term opioid therapy for chronic pain is associated with increased risks for side effects and misuse, diversion and opioid dependence.5
