Objective: To review the new indication of cyclin-dependent kinase (CDK4/6) inhibitor abemaciclib for the adjuvant treatment of hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2−), axillary lymph node (LN) positive early breast cancer (EBC) at high risk of recurrence and a Ki-67 ≥20%. Data Sources: A literature search was performed through PubMed, ClinicalTrials.gov, and Food and Drug Administration (FDA) website (February 1, 2018, to December 23, 2021) to identify relevant information. Study Selection and Data Extraction: Human and animal studies related to pharmacology, pharmacokinetics, efficacy, and safety of abemaciclib were identified. Data Synthesis: Addition of abemaciclib to standard of care endocrine therapy (ET) for patients with high-risk clinicopathologic features and Ki-67 ≥20% demonstrated 30% reduction in the risk of developing invasive disease and distant recurrence. At 15.5 months, abemaciclib + ET demonstrated a significant improvement in invasive disease-free survival (IDFS) vs ET alone (hazard ratio [HR], 0.75; 95% confidence interval [CI], 0.60-0.93, P = 0.01). At 27 months, IDFS benefit was maintained (HR, 0.70; 95% CI, 0.59-0.82, P < 0.0001). Diarrhea occurred in more than 80% of patients in the abemaciclib arm. Relevance to Patient Care and Clinical Practice: This review describes the clinical applicability of adjuvant abemaciclib for patients with HR+, HER2− EBC at high risk for recurrence. Conclusion: Adjuvant abemaciclib significantly reduces the risk for early development of invasive disease and distant recurrence in patients with HR+, HER2− node positive EBC. Longer follow-up is needed to determine the impact of adjuvant abemaciclib on late disease recurrence and survival outcomes.

Objective: This study is a comprehensive review of the clinical pharmacology, pharmacokinetics, efficacy, safety, and clinical applicability of amivantamab-vmjw for metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion (exon20ins) mutation. Data Synthesis: The literature search to identify clinical trials returned only the CHRYSALIS phase 1 study. In a phase I trial, amivantamab-vmjw was associated with an overall response rate (ORR) of 40% (95% CI, 29–51) in the EGFR exon20ins NSCLC patient population (n = 81) after platinum-based chemotherapy. There were 3 complete responses (CRs) and 29 partial responses (PRs). The median duration of response (DOR) was 11.1 months (95% CI, 6.9—not reached; NR). The median progression-free survival (PFS) was 8.3 months (95% CI, 6.5–10.9), and overall survival (OS) was 22.8 months (95% CI, 14.6—NR). Application to Clinical Practice: This review summarizes the pharmacology, clinical evidence, and use of amivantamab-vmjw for patients with locally advanced or metastatic NSCLC with EGFR exon20ins mutation. Conclusion: The FDA approval of amivantamab-vmjw, the first bispecific antibody to target the exon20ins mutation, represents an important advancement in the treatment of patients with NSCLC with limited effective treatment options. The initial findings of the CHRYSALIS trial demonstrate an overall tumor response benefit with an acceptable safety profile.

Despite the situation where fashion companies are struggling due to the COVID-19 pandemic, the global secondhand clothes market is showing remarkable growth. In line with this global trend, Korea's exports of secondhand clothes are steadily increasing. Unlike previous studies that have focused only on the domestic market, this study analyzed the impact of consumption values of secondhand clothes through comparative studies between countries. Ghana, a major gateway to West Africa, is an important importer of secondhand clothes and a developed brokerage trade that re-exports secondhand clothes to neighboring countries. The purpose of this study is to compare the differences between Korea and Ghana in the impact of the consumption value of secondhand clothes on the evaluation criteria and purchase intention. The results confirmed that the impact of consumption values of secondhand clothes on evaluation criteria and purchase intention differed between countries. In Korea, all three dimensions of the consumption values had direct and indirect effects, but in Ghana, environmental and functional values were only indirectly connected to purchase intention through evaluation criteria.
