Project description:In the adjuvant setting for malignant melanoma, interferon (IFN)-α-2b and pegylated (PEG) IFN-α-2b were approved in several countries including the USA before these were approved in Japan. To resolve the "drug-lag" issue, this phase I study was designed to evaluate the safety and tolerability in Japanese patients with stage II or III malignant melanoma who had undergone surgery, by treating with PEG IFN-α-2b. As with a previously reported phase III study, patients were to receive PEG IFN-α-2b 6 μg/kg per week s.c. during an 8-week induction phase, followed by a maintenance phase at a dose of 3 μg/kg per week up to 5 years. Dose-limiting toxicity and pharmacokinetics were assessed during the initial 8 weeks. Of the nine patients enrolled, two patients had dose-limiting toxicities that resolved after discontinuation of treatment. The most frequently reported drug-related adverse events (DRAE) included pyrexia, decreased neutrophil and white blood cell counts, and arthralgia. Grade 3 DRAE included decreased neutrophil count. No deaths, serious adverse events and grade 4 adverse events were reported. Distant metastasis occurred in one patient. No apparent differences in area under the concentration-time curve and maximum observed serum concentration were observed between Japanese and historical non-Japanese pharmacokinetic data, suggesting no marked racial differences. No neutralizing antibody was detected in these patient samples. PEG IFN-α-2b was tolerated in Japanese patients, and eventually approved in Japan in May 2015 for adjuvant therapy in patients with stage III malignant melanoma. Because the number of patients was limited, further investigation would be crucial.

Project description:PurposeInterferon alpha 2b (IFN-α2b) has been used as an adjunctive agent to treat conjunctival melanoma (CM), however its efficacy is unproved due to a paucity of data. We present 5 cases of incompletely excised CM lesions to inform clinical decision making regarding the adjunctive use of IFN-α2b.ObservationsWe identified all biopsy proven CM cases treated between 1997 and 2017 at the University of Iowa. Of these, we analyzed cases in which topical IFN-α2b drops were prescribed after the initial excision to treat surgical margins that were positive for primary acquired melanosis [PAM] with or without atypia or invasive CM. We noted the origin of CM (nevus, PAM, or de novo), presence and location of margins positive for residual melanoma, duration of IFN-α2b treatment, recurrences, time to recurrence, and outcome at last follow-up. Topical IFN-α2b drops (1 million IU/mL 4 times daily for 3-6 months) were used as adjunctive therapy in 5 cases following incomplete surgical excision of CM. The preceding lesion was PAM in 4 cases and compound nevus in 1 case. In 2 cases, margins were positive for PAM with atypia and both resulted in remission of melanoma at 54 and 33 months, respectively. However, in 3 cases, margins were positive for invasive melanoma and all 3 developed recurrence of melanoma despite IFN-α2b use.Conclusions and importanceThere are limited data regarding the efficacy of IFN-α2b as adjunctive therapy for incomplete excision of CM lesions. In this series, adjunctive topical IFN-α2b did not prevent recurrence in cases with surgical margins positive for invasive melanoma. Our results indicate that caution should be exercised when considering adjunctive IFN-α2b to treat CM lesions not excised completely.

Project description:Retinopathy is a rare side effect of interferon α-2b treatment. The goal of this study was to prospectively investigate the clinical characteristics of Chinese patients with melanomas who developed retinopathy following high doses of interferon α-2b (HD-IFN) therapy. The study included 56 melanoma stage I-III patients that were treated with HD-IFN. Fourty-three patients developed HD-IFN-induced retinopathies. Forty-three melanoma patients (76%) developed retinopathy after being treated with HD-IFN. Among these patients, 49% had cotton-wool spots, 19% had retinal hemorrhage, and 30% had retinal hemorrhage. The median time of occurrence of retinopathy was 4 weeks after treatment, and the median time of duration was 4 weeks. No patient showed other symptoms except one who had blurred vision. A comparison of clinical characteristics (age, gender, primary site, stage, and ulceration) and laboratory examinations (white blood cell and platelet counts, hemoglobin, serum lactate dehydrogenase, alanine transaminase, aspartate aminotransferase, triiodothyronine, thyroxine, thyroid-stimulating hormone, and lipid) between the HD-IFN-induced retinopathy patients and nonretinopathy patients did not show any significant differences (P > 0.05). Although all patients that developed retinopathy had diabetes or hypertension, an equal percentage of patients were without retinopathy had diabetes or hypertension. HD-IFN therapy in patients with melanomas may induce mild retinopathy. Our results; however, do not necessarily suggest to discontinue the HD-IFN treatment because retinopathy is a reversible disorder.

Project description:BackgroundAdjuvant ipilimumab was found to improve the overall survival and reduce toxicity compared to high-dose interferon (HDI) in patients with resected, high-risk melanoma. However, the cost of ipilimumab is substantially higher than HDI. This study evaluates the cost-effectiveness of ipilimumab as an adjuvant treatment in melanoma from a healthcare perspective.MethodsWe designed a Markov model simulating resected, high-risk melanoma patients receiving either ipilimumab or HDI. Transition probabilities, including risks of survival, disease progression, and toxicity, were ascertained from clinical trial data. Costs and quality of life measurements (health utilities) were extracted from the literature. Incremental cost-effectiveness ratios (ICERs), defined as incremental costs divided by incremental quality-adjusted life-years (QALYs), assessed cost-effectiveness. ICERs <$100,000/QALY were deemed cost-effective. We measured model uncertainty with one-way and probabilistic sensitivity analyses.ResultsIn our base case model, ipilimumab increased costs by $107,100 and increased effectiveness by 0.43 QALY, yielding an ICER of $392,600/QALY. Our model was moderately sensitive to the costs of ipilimumab, though the cost of ipilimumab would need to decrease by 44% for ipilimumab to become cost-effective compared to HDI. The model was not sensitive to survival, toxicity, or other costs. Probabilistic sensitivity analysis showed that HDI would remain the cost-effective treatment option 96.2% of the time at a willingness-to-pay threshold of $100,000/QALY.ConclusionsAdjuvant ipilimumab increases the survival and decreases the toxicity compared to HDI in resected, high-risk melanoma patients, though this would not be considered cost-effective due to the high price of ipilimumab.

Project description:PurposeHigh-dose pegylated interferon ?-2b (peginterferon ?-2b) significantly decreased disease recurrence in patients with resected stage III melanoma in a clinical study. We investigated the pharmacokinetics (PK) and safety of high-dose peginterferon ?-2b in patients with high-risk melanoma.MethodsFor PK analysis, 32 patients received peginterferon ?-2b 6 ?g/(kg week) subcutaneously for 8 weeks (induction) then 3 ?g/(kg week) for 4 weeks (maintenance). PK profiles were determined at weeks 1, 8, and 12. Exposure-response relationships between peginterferon ?-2b and absolute neutrophil count (ANC) and alanine aminotransferase (ALT) level were also studied.ResultsPeginterferon ?-2b was well-absorbed following SC administration, with a median T (max) of 24 h. Mean half-life estimates ranged from 43 to 51 h. The accumulation factor was 1.69 after induction therapy. PK parameters showed moderate interpatient variability. PK profiles were described by a one-compartmental model with first-order absorption and first-order elimination. Toxicity was profiled and was acceptable; observed side effects were similar to those previously described. Dose reduction produced proportional decreases in exposure and predictable effects on ANC in an Imax model; however, a PK/pharmacodynamic (PK/PD) relationship between peginterferon ?-2b and ALT could not be established with high precision.ConclusionsPeginterferon ?-2b was well-absorbed and sustained exposure to peginterferon ?-2b was achieved with the doses tested. These data confirm and extend previous PK observations of peginterferon ?-2b in melanoma and solid tumors. Our PK/PD model of exposure and ANC effect provides useful information for prediction of peginterferon ?-2b-related hematologic toxicity.

Project description:Combination immunotherapy can overcome the limited objective response rates of PD-1 blockade. Interferon alpha (IFN-α) has been proven to be effective in modulating immune responses and may enhance the clinical responses to PD-1 blockade. According to clinical practice guidelines, IFN-α was recommended as adjuvant therapy for stage IIB/C melanoma patients. However, the impact of prior IFN-α therapy on the efficacy of subsequent PD-1 blockade in melanoma has not been previously reported. Therefore, we performed a retrospective analysis for melanoma patients and addressed whether prior IFN-α therapy enhanced adjuvant pembrolizumab as later-line treatment. Fifty-six patients with resectable stage III/IV melanoma who received adjuvant therapy with pembrolizumab were retrospectively enrolled in this study. Notably, 25 patients received adjuvant pegylated IFN-α (PEG-IFN-α) in the prior line of treatment while 31 patients did not receive prior PEG-IFN-α therapy. Cox regression analysis showed that prior PEG-IFN-α therapy was associated with the efficacy of later-line adjuvant pembrolizumab (hazard ratio=0.37, 95% CI 0.16-0.89; P = 0.026). The recurrence rates after treatment with adjuvant pembrolizumab were significantly reduced in the prior PEG-IFN-α group (P < 0.001). The Kaplan-Meier analysis also showed that recurrence-free survival (RFS) after adjuvant pembrolizumab therapy was prolonged by prior PEG-IFN-α treatment (median RFSPem 8.5 months vs. 4.5 months; P = 0.0372). These findings indicated that prior PEG-IFN-α could enhance the efficacy of adjuvant pembrolizumab. The long-lasting effects of PEG-IFN-α provide a new rationale for designing combination or sequential immunotherapy.

Project description:PurposeTrial E1609 demonstrated superior overall survival with ipilimumab 3 mg/kg (ipi3) compared to high-dose interferon (HDI) for patients with resected high-risk melanoma. To inform treatment tolerability, we compared health-related quality of life (HRQoL), gastrointestinal (GI), and treatment-specific physical and cognitive/emotional symptoms. We also compared treatment-specific concerns between all arms.MethodsWe assessed HRQoL using the Functional Assessment of Cancer Therapy-General, physical and cognitive/emotional concerns using the FACT-Biologic Response Modifier subscale, and GI symptoms with the Functional Assessment of Chronic Illness Therapy-Diarrhea subscale pre-treatment and every 3 months. The primary outcome was the difference in HRQoL at 3 months between ipi3/ipi10 vs. HDI.Results549 patients (n = 158 ipi3; n = 191 ipi10; n = 200 HDI) were analyzed. 3-month completion was 58.7%. Compared to HDI, ipilimumab patients reported better HRQoL (ipi3 = 87.5 ± 14.6 vs. HDI = 74.7 ± 15.4, p < .001; ipi10 = 84.9 ± 16.5 vs. HDI, p < .001) and fewer physical (ipi3 = 22.3 ± 4.6 vs. HDI = 17.1 ± 5.4, p < .001; ipi10 = 21.8 ± 5.0 vs. HDI p < .001) and cognitive/emotional (ipi3 = 18.6 ± 4.4 vs. HDI = 15.0 ± 5.3, p < .001; ipi10 = 17.7 ± 4.8 vs. HDI p < .001) concerns, but worse GI symptoms (ipi3 = 40.8 ± 5.0 vs. HDI = 42.2 ± 2.9, p = .011; ipi10 = 39.5 ± 7.0 vs. HDI, p < .001). Fewer ipilimumab patients reported worsening treatment-specific concerns (e.g., 52% of ipi3 and 58% of ipi10 reported worsening fatigue vs. 82% HDI, p's < .001).ConclusionPROs demonstrated less toxicity of ipi3 compared to HDI and ipi10. Priorities for symptom management among patients receiving ipilimumab include GI toxicities, fatigue, weakness, appetite loss, arthralgia, and depression.Trial registrationNCT01274338, January 11, 2011 (first posted date) https://clinicaltrials.gov/ct2/show/NCT01274338?term=NCT01274338&draw=2&rank=1 .

Project description:The possibility that cytokine administration could enhance the antitumor effects of proteasome inhibition was explored. It was found that coadministration of bortezomib and interferon-α (IFN-α) induced synergistic apoptosis in human melanoma cell lines and prolonged survival in a murine model of melanoma. A phase I study was conducted to determine the tolerability and the maximum tolerated dose of bortezomib when administered in combination with IFN-α-2b to patients with metastatic melanoma. Patients were treated on a 5-week cycle. In week 1 of cycle 1, patients received 5 million U/m(2) IFN-α subcutaneously thrice weekly. During weeks 2-4 of cycle 1, bortezomib was administered intravenously weekly along with IFN-α thrice weekly. There was a treatment break during week 5. After cycle 1, bortezomib was administered in combination with IFN-α. Bortezomib was administered in escalating doses (1.0, 1.3, or 1.6 mg/m) to cohorts of 3 patients. Sixteen patients were treated (8 women, 8 men; median age 59 y). Common grade 3 toxicities included fatigue (5), vomiting (3), and diarrhea (3). Grade 4 toxicities included fatigue (3) and lymphopenia (1). The maximum tolerated dose for bortezomib was 1.3 mg/m(2). One patient had a partial response, and 7 had stable disease. Progression-free survival was 2.5 months, and overall survival was 10.3 months. Bortezomib administration did not augment the ability of IFN-α to induce phosphorylation of STAT1 in circulating immune cells; however, it did lead to reduced plasma levels of proangiogenic cytokines. The combination of bortezomib and IFN-α can be safely administered to melanoma patients.

Project description:IntroductionMultiple agents are approved in the adjuvant setting of completely resected high-risk (stages IIC-IV) malignant melanoma. Subgroups may benefit differently depending on the agent used. We performed a systematic review and meta-analysis to evaluate the efficiency and tolerability of available options in the post interferon era across following subgroups: patient age, stage, ulceration status, lymph node involvement, BRAF status.MethodsThe PubMed and Cochrane Library databases were searched without restriction in year of publication in June and September 2020. Data were extracted according to the PRISMA Guidelines from two authors independently and were pooled according to the random-effects model. The predefined primary outcome was recurrence-free survival (RFS). Post-data extraction it was noted that one trial (BRIM8) reported disease-free survival which was defined in the exact same way as RFS.ResultsFive prospective randomized placebo-controlled trials were included in the meta-analysis. The drug regimens included ipilimumab, pembrolizumab, nivolumab, nivolumab/ipilimumab, vemurafenib, and dabrafenib/trametinib. Adjuvant treatment was associated with a higher RFS than placebo (HR 0.57; 95% CI= 0.45-0.71). Nivolumab/ipilimumab in stage IV malignant melanoma was associated with the highest RFS benefit (HR 0.23; 97.5% CI= 0.12-0.45), followed by dabrafenib/trametinib in stage III BRAF-mutant melanoma (HR 0.49; 95% CI= 0.40-0.59). The presence of a BRAF mutation was associated with higher RFS rates (HR 0.30; 95% CI= 0.11-0.78) compared to the wildtype group (HR 0.60; 95% CI= 0.44-0.81). Patient age did not influence outcomes (≥65: HR 0.50; 95% CI= 0.36-0.70, <65: HR 0.58; 95% CI= 0.46-0.75). Immune checkpoint inhibitor monotherapy was associated with lower RFS in non-ulcerated melanoma. Patients with stage IIIA benefited equally from adjuvant treatment as those with stage IIIB/C. Nivolumab/ipilimumab and ipilimumab monotherapy were associated with higher toxicity.ConclusionAdjuvant therapy should not be withheld on account of advanced age or stage IIIA alone. The presence of a BRAF mutation is prognostically favorable in terms of RFS. BRAF/MEK inhibitors should be preferred in the adjuvant treatment of BRAF-mutant non-ulcerated melanoma.
