The physical dependence on prescription opioids among cancer survivors remains an under-investigated area, with a scarcity of well-designed prospective studies. This single-arm, phase-2 clinical trial in Korea assessed the efficacy and safety of a transdermal buprenorphine patch TBP in managing physical dependence on prescription opioids in cancer survivors, as confirmed through the DSM-5 criteria or psychiatric consultation for opioid withdrawal. The primary outcome was the rate of successful opioid discontinuation, as measured by a negative urine-drug screening at 8 weeks. Key secondary outcomes included the resumption of prescribed opioids, changes in both the Clinical Opioid Withdrawal Scale COWS and morphine equivalent daily dose MEDD , and assessments related to the psychological and physiological aspects of dependence and safety. Thirty-one participants were enrolled. Desire to use opioids reduced from 7. Toxicities related to TBP were mild and manageable, without severe precipitated withdrawal symptoms. TBP may be considered as an alternative therapeutic option in cancer survivors physically dependent on prescription opioids, especially where sublingual formulations are unavailable. Transdermal buprenorphine patch may offer a promising approach for managing physical dependence on prescription opioids in cancer survivors, particularly where sublingual formulations are unavailable. Primary care physicians may be effectively able to initiate this treatment in patients with mild withdrawal symptoms, potentially reducing the need for immediate referral to addiction specialists and mitigating undertreatment of cancer-related pain due to concerns about physical dependence. Aberrant opioid-related behavior has become a major issue worldwide, owing to an increased usage of prescription opioids to manage chronic pain. In the United States, opioid overdose crisis has emerged as a significant social problem among patients without cancer. Deaths due to synthetic opioid-related overdoses increased by more than 6-fold between and Similarly, in Korea, the incidence of high risk for aberrant opioid-related behavior in patients with cancer was low 0. Enhanced regulations and concerns regarding the long-term use of opioids, even in patients with cancer near the end-of-life, have also contributed to this shift in practice. Another barrier in prescribing opioids to patients with cancer is that many primary care physicians, especially in Korea, are unfamiliar with proper management of opioid use disorder OUD. Behavioral therapies, such as cognitive-behavioral therapy and motivational interviewing, address the psychological aspects of addiction and help patients modify their behaviors and attitudes related to drug-use. Buprenorphine is particularly beneficial owing to its unique pharmacological properties, including a ceiling effect, which reduces the risk of overdose. Moreover, the combination of buprenorphine and naloxone in certain formulations decreases the risk of misuse, making it a safer and more controlled option for managing OUD. Therefore, buprenorphine is the preferred choice for many opioid replacement therapy programs. However, data on the role of buprenorphine in the management of OUD in patients with cancer are limited. In a qualitative study using the modified Delphi process, experts agreed on continuing treatment with buprenorphine-naloxone in patients with advanced cancer, pain, and OUD simultaneously and on adding a full opioid agonist in patients with a prognosis of weeks to months. Importantly, a sublingual formulation of buprenorphine is not available in Korea; only a transdermal patch formulation is available. In North America, among patients without cancer with chronic pain or individuals dependent on nonprescription opioids, a transdermal buprenorphine patch TBP used as a bridging therapy before sublingual buprenorphine induction therapy or as monotherapy effectively managed withdrawal symptoms related to opioids. The duration of TBP application ranged from 2 to 14 weeks. No resumption of prescribed opioids have been reported. Given these findings and the challenges of managing OUD and withdrawal symptoms associated with prescription opioids in cancer survivors, we aimed to assess and validate the efficacy and safety of TBP in managing physical dependence on prescription opioids in this population. This single-arm phase II clinical trial was performed at 12 institutions in Korea. Inclusion criteria were age 19 years and older, patients willing to discontinue prescription opioids and voluntarily participated in clinical trials, patients previously managed with prescription opioids for cancer pain, but currently not requiring opioids due to the absence of pain, patients who met the Opioid Withdrawal DSM-5 diagnostic criteria 23 or whose physical dependence on prescription opioids had been confirmed through a psychiatric consultation, appropriate bone marrow and liver functions, and failure to discontinue prescription opioids through a simple tapering process due to withdrawal symptoms. Additionally, patients whose cancer was in complete response, showed no progression, or had not relapsed for a period of 6 months or more were eligible to participate, focusing on stable cancer survivors. Treatment protocol for managing physical dependence on prescription opioids in cancer survivors. The induction phase involves discontinuing all prescription opioids responsible for physical dependence, followed by an immediate transition to transdermal buprenorphine patch TBP due to its slower onset. For doses exceeding mg morphine equivalent daily dose, TBP is combined with a reduced dose of the offending opioid. Written informed consent and urinary drug screening UDS were obtained from all participants. The process began by ceasing the use of all offending prescription opioids that had led to physical dependence. This was followed by rotation to TBP without an opioid-free interval because of the slower onset time of TBP compared to that of the sublingual formulation. The patch was attached to undamaged skin on the outer upper arm, upper chest, upper abdomen, or lateral aspect of the chest. Dosages for TBPs were 5, 10, 20, 35, The frequency of change usually depends on the patch brand. One brand was designed to be replaced every 4 days, whereas the other brand was intended for replacement every 7 days. Simultaneous application of 2 different brands of TBP was not recommended. If TBP application alone did not sufficiently alleviate withdrawal symptoms, the protocol allowed the use of adjunctive medications 27 and rescue opioids. Regular follow-ups were conducted at least every 2 weeks to assess whether the participant was stable with the current TBP dose. These criteria all of which must be met include the absence of withdrawal symptoms and cravings at the current TBP dose, no need for rescue medication, no usage of other opioids, and clear motivation from the patient to discontinue opioid use. This phase was crucial for observing the reappearance of withdrawal symptoms and resumption of prescribed opioids. Regular follow-ups were scheduled to monitor the participants for resumption of prescribed opioids, side effects from TBP, and any abnormal behaviors related to opioid use. Power analysis, performed using PASS statistical software, indicated a study power of 0. FAS comprised all participants who received at least one dose of the study treatment and had at least one post-baseline assessment, whereas PP included those assessed at the 8-week follow-up visit, aligning with the timepoint for the primary endpoint assessment. For continuous variables in the matched samples, paired t -test or Wilcoxon signed-rank test was applied based on data normality. The enrollment was closed prematurely owing to the slow recruitment rate and consensus among all researchers that there might be no additional enrollment. In this participant, UDS was considered negative if all of the following conditions were met: denial of tapentadol use, negative UDS for other opioids, and no prescription of any opioids by researchers or other health care professionals at the 8-week follow-up visit. Among the 31 ITT participants, 3 withdrew before the first follow-up visit: 2 were lost to follow up, and one withdrew consent. Consequently, 28 participants FAS population were assessed for efficacy and safety at least once after enrollment. Baseline characteristics of ITT population are tabulated Table 1. Most patients were male Among them, Cancer types represented in the study were diverse, with colorectal being the most common Most participants Mean COWS score was 6.

Table 2 describes the data for resumption of prescribed opioids, and the discontinuation or retention of TBP. None of these 11 participants experienced resumption of prescribed opioids during the study period. A male participant who had successfully stopped using long-acting oxycodone developed a physical dependence on TBP that manifested as agitation following its cessation. Of them, 4 successfully discontinued the offending opioids. However, another 4 participants were unable to discontinue their offending opioids, and one experienced resumption of prescribed opioids after initially discontinuing them. Including another case, there were consequently 2 participants who experienced resumption of prescribed opioids after discontinuing the offending opioids. Five participants received rescue opioids other than the offending opioids and TBP before the 8-week follow-up visit. Secondary efficacy endpoints were compared at baseline and 8-week follow-up visit in the PP population Figure 4. Evaluation of secondary efficacy endpoints at baseline and 8-week follow-up. The mean COWS score reduced from 5. The mean NRS score for the desire to use opioids decreased from 7. Over the 8-week study period, the total FACT-G score and its subscales increased, indicating a potential improvement in quality of life. However, these improvements were modest and did not reach statistical significance Supplementary Table S2. None of the participants, including the 5 who received TBP simultaneously with a reduced dose of offending opioids, experienced severe precipitated withdrawal by TBP that led to withdrawal from the study during the induction and stabilization phase. Other adverse events reported by 8 of the 31 participants were generally mild, primarily grade 1 symptoms, such as constipation, diarrhea, abdominal pain, dizziness, insomnia, dry mouth, nausea, and itching. Two participants experienced grade 2 symptoms. One participant with grade 2 scalp pain unrelated to TBP, discontinued TBP before the 8-week follow-up visit and continued using his offending opioid. Another patient who experienced grade 2 itching sensation related to TBP, discontinued TBP after the 8-week follow-up visit and successfully discontinued the long-acting oxycodone. This is the first clinical trial to assess the efficacy and safety of TBP in managing physical dependence on prescription opioids among cancer survivors. Secondary outcomes revealed significant reductions in MEDD, COWS, and desire to use opioids, and improvements in the willingness and distress to discontinue opioids, indicating the role of TBP in reducing the physical and psychological aspects of opioid dependence. The safety profile of TBP is generally favorable, with mild and manageable adverse events and no severe precipitated withdrawal during the induction and stabilization phases. Specifically, Despite its slower onset and lower dose flexibility than sublingual buprenorphine, TBP has compensatory advantages for managing withdrawal symptoms on prescribed opioids. The reduced risk of diversion owing to the controlled delivery system and favorable safety profile of TBP are beneficial in outpatient and long-term management settings. Continuous buprenorphine release of TBP ensures stable drug levels along with the convenience of non-daily dosing, which enhances patient compliance and adherence. Additionally, TBP does not require an opioid-free interval before rotation from the offending opioids because of its slow and steady release of medication, thus preventing precipitated withdrawal. The lower success rate in more challenging cases, such as those involving short-acting, multiple, or potent opioids, suggests that TBP might be less effective in managing severe withdrawal symptoms. These patients may require immediate flexible symptom management. Additionally, the follow-up period in our study was relatively short. This shorter follow-up duration may have limited our ability to fully assess the long-term efficacy of TBP, potentially leading to an overestimation of its success rate in discontinuing prescribed opioids and an underestimation of the rate of resumption of prescribed opioids. In our study, discontinuation of TBP was permitted according to the criteria of the study protocol. However, in the general population or patients without cancer with OUD, retention of buprenorphine is strongly recommended because discontinuation of buprenorphine is frequently associated with an increased risk of resumption of opioid use. This difference may be attributed to the relatively mild severity of the withdrawal symptoms and less frequent inclusion of cases with psychological dependence in this study. Moreover, the short-term follow-up period in our study may not have been adequate to fully assess the risk of delayed resumption of prescribed opioids. Nonetheless, our findings prompted a reevaluation of the necessity for long-term buprenorphine retention in cancer survivors with mild withdrawal symptoms on prescription opioids. Another methodological issue related to our study is the initial dose of TBP because an equianalgesic dose as applied in our study may not be the same as the dose needed to control withdrawal symptoms. Further studies are required to validate the appropriate initial TBP dose. The findings of this study should be interpreted with caution owing to several limitations. This study had a single-arm design without a control group, making it difficult to conclusively attribute the outcomes to the intervention alone. Given the low incidence of OUD in Korean patients with cancer, 3 , 4 this study faced challenges in participant recruitment, resulting in a small sample size, which impacted the reliability and generalizability of the results. Moreover, a follow-up period of Conducted exclusively in Korea, the findings of this study might not be fully applicable to regions with access to different buprenorphine formulations. The study cohort predominantly comprised participants with milder symptoms of physical dependence, which significantly limits the applicability of the findings to a broader patient population, especially those experiencing more severe forms of withdrawal symptoms. Moreover, by including participants solely based on their withdrawal symptoms and not considering the full diagnostic criteria for OUD, the study results may not be directly applicable for assessing the efficacy of TBP for treating OUD. Additionally, this consideration is crucial because the DSM-5 indicates that tolerance and withdrawal cannot be considered as criteria for diagnosing OUD in patients on long-term opioid therapy. Although a psychiatric expert reviewed our intervention protocol and developed the motivational enhancement therapy program, it was conducted by a medical oncologist for all participants, and its efficacy was not assessed. This has been criticized for representing an absence of a comprehensive multidisciplinary approach, which is crucial for managing OUD. To conclude, our research indicates that TBP could serve as an effective alternative to sublingual formulations for managing physical dependence on prescription opioids in cancer survivors, particularly where sublingual options are unavailable. Additionally, this study suggests that primary care physicians can effectively initiate TBP use in cancer survivors who have mild withdrawal symptoms and face difficulty in discontinuing their offending opioids solely through dose tapering; thereby reducing the need for immediate referral to addiction specialists. This approach has the potential to mitigate the undertreatment of cancer pain by reducing unnecessary concerns about opioid dependence. Further research involving larger and more diverse patient groups, and incorporating comprehensive multidisciplinary management with behavioral interventions, is required to validate these findings and evaluate the long-term impact of TBP in managing OUD and physical dependence on prescription opioids in cancer care.
