RESUMO
BACKGROUND: Pembrolizumab plus epacadostat (indoleamine 2,3-dioxygenase-1 inhibitor) was well tolerated in Japanese patients with advanced solid tumors in part A of the nonrandomized, open-label, phase 1 KEYNOTE-434 study (NCT02862457). We report results from part B, which evaluated epacadostat plus pembrolizumab and chemotherapy in Japanese patients with advanced non-small-cell lung cancer (NSCLC). METHODS: Eligible patients aged ≥ 20 years had histologically or cytologically confirmed stage IIIB or IV NSCLC with no prior systemic therapy, and ECOG performance status of 0 or 1. Patients received epacadostat 100 mg orally twice-daily, pembrolizumab 200 mg intravenously every-3-weeks for ≤ 35 cycles, and 4 cycles of chemotherapy (cohort 1: cisplatin plus pemetrexed, non-squamous; cohort 2: carboplatin plus pemetrexed, non-squamous; cohort 3: carboplatin plus paclitaxel, squamous or non-squamous). Primary endpoint was incidence of dose-limiting toxicities (DLTs). Following unfavorable results from other studies, a protocol amendment removed epacadostat from the treatment combination. RESULTS: Of 19 patients, 7 were enrolled in cohort 1, and 6 each in cohorts 2 and 3. Median follow-up was 13.7 (range, 4.2-27.8) months. Five of 17 (29%) DLT-evaluable patients experienced ≥ 1 DLT (cohort 1, n = 1; cohorts 2 and 3, n = 2 each); most commonly maculopapular rash (grade 3, n = 3) and increased alanine aminotransferase (grade 2, n = 1; grade 3, n = 2). All patients experienced treatment-related adverse events (AEs); 58% experienced grade 3 or 4 treatment-related AEs. Objective response rate was 47%. CONCLUSION: The combination of epacadostat plus pembrolizumab and chemotherapy was found to be tolerable in Japanese patients with advanced NSCLC.

BACKGROUND: Targeted therapy is now the standard of care in driver-oncogene-positive non-small cell lung cancer (NSCLC). Its initial clinical effects are remarkable. However, almost all patients experience treatment resistance to targeted therapy. Hence, chemotherapy is considered a subsequent treatment option. In patients with driver-oncogene-negative NSCLC, combined immune checkpoint inhibitors (ICIs) and chemotherapy as the first-line therapy has been found to be beneficial. However, the efficacy of ICI plus chemotherapy against driver-oncogene-positive NSCLC other than epidermal growth factor receptor mutation and anaplastic lymphoma kinase fusion is unclear. METHODS: Using the hospital medical records, we retrospectively reviewed advanced or recurrent NSCLC patients who were treated with chemotherapy with or without ICIs at Aichi Cancer Center Hospital between January 2014 and January 2023. Patients with druggable rare mutations such as KRAS-G12C, MET exon 14 skipping, HER2 20 insertion, BRAF-V600E mutations, and ROS1 and RET rearrangements were analyzed. RESULTS: In total, 61 patients were included in this analysis. ICI plus chemotherapy was administered in 36 patients (the ICI-chemo group) and chemotherapy in 25 patients (the chemo group). The median progression-free survival (PFS) rates were 14.0 months in the ICI-chemo group and 4.8 months in the chemo group (hazard ratio [HR] = 0.54, 95% confidence interval [CI] = 0.28-1.01). The median overall survival rates were 31.3 and 21.7 months in the ICI-chemo and chemo groups, respectively (HR = 0.70, 95% CI = 0.33-1.50). Multivariate Cox regression analysis of PFS revealed that HER2 exon 20 insertion mutation was significantly associated with a poorer PFS (HR: 2.39, 95% CI: 1.19-4.77, P = 0.014). Further, ICI-chemo treatment was significantly associated with a better PFS (HR: 0.48, 95% CI: 0.25-0.91, P = 0.025). CONCLUSION: ICI plus chemotherapy improves treatment efficacy in rare driver-oncogene-positive NSCLC.

BACKGROUND/AIM: The safety and efficacy of anti-angiogenic agents in patients with cancer with proteinuria and a history of proteinuria are not well established. This systematic review aimed to answer these questions. MATERIALS AND METHODS: We searched three electronic databases for articles published until June 18, 2021. The main outcomes used were "death", "renal impairment", and "proteinuria impairment". RESULTS: After screening 303 references in the PubMed, Cochrane Library, and ICHUSHI-web databases, this review included five studies on renal cell carcinoma (RCC). In patients with metastatic RCC, the hazard ratio of the presence of (or having) proteinuria (1+ or higher) at baseline was 0.82 (0.23-2.97); thus, proteinuria was not significantly associated with the outcome of death. No significant deterioration in kidney function was observed in patients with proteinuria. Although proteinuria at baseline was a significant risk factor for proteinuria progression during and after treatment, most patients maintained grade 1 or 2 proteinuria and continued treatment without dose reduction or discontinuation. CONCLUSION: While weak evidence suggests that proteinuria at the start of treatment with anti-angiogenic agents might be a risk factor for worsening proteinuria, it was not significantly associated with death or renal impairment.

Background/Aim: Hypomagnesemia is a common side effect of anti-epidermal growth factor receptor (EGFR) antibodies, which may lead to arrhythmia. However, there are no evidence-based guidelines for magnesium (Mg) supplementation in the management of hypomagnesemia in patients with anti-EGFR antibodies. Therefore, we performed a systematic review to address clinical questions regarding these cancer patients. Materials and Methods: Three electronic databases were searched for articles published until June 18, 2021. The main outcomes used were "anti-EGFR antibody" and "hypomagnesemia". Results: After screening 78 references in PubMed, Cochrane Library, and ICHUSHI-web databases, three studies were included in the review. One study revealed the effectiveness of Mg supplementation in the management of hypomagnesemia in patients receiving cetuximab. However, no studies have investigated whether correcting hypomagnesemia can lead to the suppression of arrhythmias as a clinical outcome. Conclusion: Weak evidence suggests that Mg supplementation, as a preventive measure when developing hypomagnesemia following the initiation of anti-EGFR antibody therapy, may prevent the worsening of hypomagnesemia, and subsequently prevent associated arrhythmia occurrence.
RESUMO
In patients with non-small cell lung cancer (NSCLC), pre-existing interstitial lung disease (ILD) is a risk factor for the development of pneumonitis induced by immune checkpoint inhibitors (ICIs). Anti-fibrotic agents, including nintedanib, reduce the potential for acute exacerbation of idiopathic pulmonary fibrosis (IPF). However, whether nintedanib can reduce the potential for ICI-induced pneumonitis is unknown. From among 140 patients with NSCLC treated with atezolizumab monotherapy at our institution, we retrospectively investigated 4 patients with pre-existing ILD treated concurrently with nintedanib. On computed tomography (CT), a usual interstitial pneumonia (UIP) pattern was present in one patient, probable UIP pattern in one patient, and indeterminate for UIP pattern in two patients. Of those four patients with pre-existing ILD, two achieved a partial response to ICI treatment, with response durations of 8.1 and 7.6 months. The other two patients experienced progressive disease. Notable adverse events included the development of non-symptomatic grade 1 pneumonitis in the patient with a probable UIP pattern and grade 3 lower gastrointestinal hemorrhage in another patient. None of the patients experienced a worsening of respiratory symptoms. In patients with NSCLC and pre-existing ILD, nintedanib might reduce the potential for ICI-induced pneumonitis and enhance the antitumor effect.
RESUMO
Interstitial lung disease (ILD) or pneumonitis caused by epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) or immune checkpoint inhibitors (ICI) is a major concern in the treatment of non-small cell lung cancer (NSCLC). Whether the addition of vascular endothelial growth factor (VEGF) and VEGF receptor (VEGFR) inhibitors can reduce the incidence of drug-induced ILD remains unclear. We conducted a systematic review to assess the incidence of ILD induced by EGFR-TKIs or ICIs in the presence or absence of VEGF/VEGFR inhibitors in relevant randomized trials between January 2009 and October 2023. The primary outcome was the odds ratio for the incidence of ILD in all patients worldwide and Asians. Secondary outcomes were the odds ratios (ORs) of the incidence at grade-3 or higher ILD in all patients worldwide and Asians. We identified 13 randomized studies, one sub-analysis in the EGFR-TKI group, and three randomized studies in the ICI group. In the EGFR-TKI group, the OR of ILD incidence at any grade with VEGF/VEGFR inhibitors was 0.54 (95% CI, 0.32-0.90; p = 0.02), which represented a significantly lower incidence than that without VEGF/VEGFR inhibitors. Contrarily, the OR of ILD incidence at grade ≥ 3 with VEGF/VEGFR inhibitors was 1.00 (95% CI, 0.43-2.36; p = 0.99). In all subjects in the ICI group, the OR of ILD incidence at any grade with VEGF/VEGFR inhibitors was 0.78 (95% CI, 0.51-1.21; p = 0.27). The systematic review demonstrated that the addition of VEGF/VEGFR inhibitors could reduce the incidence of drug-induced ILD at any grade caused by EGFR-TKI in patients with NSCLC but could not reduce that at grade ≥ 3. The ILD induced by ICIs remains undetermined owing to the limited number of randomized trials for which ILD data are available.

RESUMO
BACKGROUND: The combination of platinum-based chemotherapy and an antibody to PD-1 or to its ligand PD-L1, with or without an antibody to CTLA-4, has improved the survival of individuals with metastatic non-small-cell lung cancer (NSCLC). However, no randomised controlled trial has evaluated the survival benefit of adding a CTLA-4 inhibitor to platinum-based chemotherapy plus a PD-1 or PD-L1 inhibitor. METHODS: This open-label, randomised, phase 3 trial was conducted at 48 hospitals in Japan. Eligible patients were aged 20 years or older with previously untreated advanced NSCLC and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients with known driver oncogenes were excluded. Participants were randomly assigned (1:1) to receive platinum-based chemotherapy (four cycles) plus pembrolizumab (pembrolizumab group) or platinum-based chemotherapy (two cycles) plus nivolumab-ipilimumab (nivolumab-ipilimumab group). The primary endpoint was overall survival and assessed in all randomly assigned patients on an intention-to-treat basis. The trial is registered in the Japan Registry for Clinical Trials, jRCTs031210013, and is now closed to new enrolment and is ongoing. FINDINGS: Between patient accrual initiation on April 6, 2021, and discontinuation of the trial on March 30, 2023, 11 (7%) of 148 patients in the nivolumab-ipilimumab group had a treatment-related death. Because of the high number of treatment-related deaths, patient accrual was terminated early, resulting in 295 patients (236 [80%] male and 59 [20%] female) enrolled; the primary analysis was done on the basis of 117 deaths (fewer than the required 329 deaths). By May 25, 2023 (data cutoff), overall survival did not differ significantly between the nivolumab-ipilimumab group and the pembrolizumab group (median 23·7 months [95% CI 17·6-not estimable] vs 20·5 months [17·6-not estimable], respectively; hazard ratio 0·98 [90% CI 0·72-1·34]; p=0·46). Non-haematological adverse events of grade 3 or worse occurred in 87 (60%) of 146 patients in the nivolumab-ipilimumab group and 59 (41%) of 144 patients in the pembrolizumab group. The pembrolizumab group tended to have a better quality of life compared with the nivolumab-ipilimumab group. INTERPRETATION: The safety and efficacy data suggest an unfavourable benefit-risk profile for nivolumab-ipilimumab combined with platinum-based chemotherapy relative to pembrolizumab combined with platinum-based chemotherapy as a first-line treatment for patients with advanced NSCLC, although a definitive conclusion awaits an updated analysis of overall survival.
