Acthar Gel in African Americans versus Non-African Americans with Symptomatic Sarcoidosis: Physician Assessment of Patient Medical Records

Introduction

Sarcoidosis is common among African Americans in the United States. Acthar® Gel is a viable option for the treatment of advanced symptomatic sarcoidosis. This study examined patient characteristics, Acthar Gel utilization, co-medication use, and treatment response based on physicians' assessments among African Americans versus non-African Americans with advanced symptomatic sarcoidosis.

Methods

Data from the medical charts of patients were used. During data collection, patients had either completed ≥1 course or received treatment with Acthar Gel for ≥6 months.

Results

This study comprised 168 African Americans and 104 non-African Americans. On average, the time since the first diagnosis of sarcoidosis was slightly longer among African Americans than non-African Americans (5.2 versus 4.3 years). Skin, heart, eyes, and joints were the most common extrapulmonary sites involved among both race groups. Shortness of breath, fatigue, bone and joint pain, and wheezing/coughing were the most frequent symptoms among both race groups. A higher proportion of African Americans versus non-African Americans were first-time Acthar Gel users and had not completed treatment during data collection. Patients in both race groups with higher starting doses of Acthar Gel therapy had a shorter treatment duration and vice-versa. A significantly lower proportion of patients among both race groups were on any co-medication after Acthar Gel initiation (p<0.0001). Further, a higher proportion of African Americans versus non-African Americans had a reduction in any co-medication use after Acthar Gel initiation. The mean daily dose of prednisone decreased among African Americans (18.5 to 10.1 mg) and non-African Americans (17.6 to 10.0 mg) after Acthar Gel initiation. Improvement in patient health status and overall symptoms was similar for both race groups.

Conclusion

Findings suggest that Acthar Gel improves health outcomes for patients with sarcoidosis, which could help to alleviate health disparities among African Americans, who are disproportionately affected by this disease.

Real-world outcomes in non-small-cell lung cancer patients with MET Exon 14 skipping mutation and brain metastases treated with capmatinib

Aim: To assess real-world clinical outcomes in patients with non-small-cell lung cancer with MET exon 14 skipping mutation and brain metastases (BM) who received capmatinib, a recently approved MET inhibitor, in routine US clinical practice. Materials & methods: Patient data were collected using a retrospective medical record review, led by participating oncologists. Eligible patients initiated treatment with capmatinib in any line, after BM diagnosis, between May 2020 and June 2021. Data on real-world overall response rate (rwORR) and real-world progression-free survival (rwPFS) were descriptively analyzed. Results: 68 eligible patients were analyzed. In patients treated with first-line (1L) capmatinib (n = 55), the rwORR was 90.9% systemically and 87.3% intracranially; median systemic rwPFS was 14.1 months. Among radiation-naive patients on 1L capmatinib (n = 20), rwORR was 85.0%, both systemically and intracranially; median systemic rwPFS was 14.1 months. Conclusion: This study showed substantial systemic and intracranial effectiveness for capmatinib in real-world setting; findings were consistent for RT-naive patients.

Characterization of Severity in Zellweger Spectrum Disorder by Clinical Findings: A Scoping Review, Meta-Analysis and Medical Chart Review

Zellweger spectrum disorder (ZSD) is a rare, debilitating genetic disorder of peroxisome biogenesis that affects multiple organ systems and presents with broad clinical heterogeneity. Although severe, intermediate, and mild forms of ZSD have been described, these designations are often arbitrary, presenting difficulty in understanding individual prognosis and treatment effectiveness. The purpose of this study is to conduct a scoping review and meta-analysis of existing literature and a medical chart review to determine if characterization of clinical findings can predict severity in ZSD. Our PubMed search for articles describing severity, clinical findings, and survival in ZSD resulted in 107 studies (representing 307 patients) that were included in the review and meta-analysis. We also collected and analyzed these same parameters from medical records of 136 ZSD individuals from our natural history study. Common clinical findings that were significantly different across severity categories included seizures, hypotonia, reduced mobility, feeding difficulties, renal cysts, adrenal insufficiency, hearing and vision loss, and a shortened lifespan. Our primary data analysis also revealed significant differences across severity categories in failure to thrive, gastroesophageal reflux, bone fractures, global developmental delay, verbal communication difficulties, and cardiac abnormalities. Univariable multinomial logistic modeling analysis of clinical findings and very long chain fatty acid (VLCFA) hexacosanoic acid (C26:0) levels showed that the number of clinical findings present among seizures, abnormal EEG, renal cysts, and cardiac abnormalities, as well as plasma C26:0 fatty acid levels could differentiate severity categories. We report the largest characterization of clinical findings in relation to overall disease severity in ZSD. This information will be useful in determining appropriate outcomes for specific subjects in clinical trials for ZSD.

Real-world treatment of patients with palbociclib for HR+/HER2-advanced/metastatic breast cancer: the Europe IRIS study

Aim: To report the Europe Ibrance Real World Insights study findings. Methods: Physicians abstracted demographic/clinical characteristics, treatment and outcomes data for women with HR+/HER2- locally advanced breast cancer (ABC) or metastatic  breast cancer (MBC) receiving palbociclib + aromatase inhibitor (AI) or palbociclib + fulvestrant. Kaplan-Meier analysis estimated progression-free rates (PFRs) and survival rates (SRs). Results: 238 physicians abstracted data for 1723 patients. For patients (>90%) initiating at 125 mg/day, dose was reduced in 18.9% of palbociclib + AI and 12.3% of palbociclib + fulvestrant patients. At 12 months, PFR for palbociclib + AI was 88.1%, and SR was 97.3%; PFR for palbociclib + fulvestrant was 79.8%, and SR was 97.5%. Conclusion: Low dose-reduction rates and favorable PFRs and SRs suggest that palbociclib + AI/fulvestrant is well tolerated and effective for HR+/HER2- ABC/MBC in real-world clinical practice.

Real-World Palbociclib Use in HR+/HER2- Advanced Breast Cancer in Canada: The IRIS Study

BACKGROUND

Palbociclib is a selective cyclin-dependent kinase (CDK) 4/6 inhibitor used in combination with aromatase inhibitors or fulvestrant for patients with hormone receptor-positive (HR+) human epidermal growth factor receptor 2 (HER2)-negative advanced/metastatic breast cancer (ABC/MBC). Palbociclib was the first CDK 4/6 inhibitor approved for HR+/HER2- ABC/MBC treatment in Canada in combination with letrozole (P+L) as an initial endocrine-based therapy (approved March 2016), or with fulvestrant (P+F) following disease progression after prior endocrine therapy (approved May 2017). The Ibrance Real World Insights (IRIS) study (NCT03159195) collected real-world outcomes data for palbociclib-treated patients in several countries, including Canada.

METHODS

This retrospective chart review included women with HR+/HER2- ABC/MBC receiving P+L or P+F in Canada. Physicians reviewed medical records for up to 14 patients, abstracting demographic and clinical characteristics, treatment patterns, and clinical outcomes. Progression-free rates (PFRs) and survival rates (SRs) at 6, 12, 18, and 24 months were estimated via Kaplan-Meier analysis.

RESULTS

Thirty-three physicians examined medical records for 247 patients (P+L, n = 214; P+F, n = 33). Median follow-up was 8.8 months for P+L and 7.0 months for P+F. Most patients were initiated on palbociclib 125 mg/d (P+L, 90.2%; P+F, 84.8%). Doses were reduced in 16.6% of P+L and 14.3% of P+F patients initiating palbociclib at 125 mg/d. The PFR for P+L was 90.3% at 12 months and 78.2% at 18 months; corresponding SRs were 95.6% and 93.0%. For P+F, 6-month PFR was 91.0%; 12-month SR was 100.0%.

CONCLUSIONS

Dose reduction rates were low and PFR and SR were high in this Canadian real-world assessment of P+L and P+F treatments, suggesting that palbociclib combinations are well tolerated and effective.
