Indolent systemic mastocytosis (ISM), a clonal mast cell disease driven by the KIT D816V mutation, can often cause debilitating dermatologic symptoms.

The phase 3 DUO-E trial demonstrated statistically significant progression-free survival (PFS) benefit with carboplatin/paclitaxel plus durvalumab followed by durvalumab with/without olaparib maintenance versus carboplatin/paclitaxel alone in advanced/recurrent endometrial cancer. We report exploratory analyses of key biomarkers and histology in the mismatch repair proficient (pMMR) subpopulation.

Approximately 60 % of lung cancer cases occur in Asia, indicating an epidemiological disparity and need for effective therapies. Amivantamab-lazertinib is approved for first-line EGFR-mutated advanced non-small cell lung cancer (NSCLC) in many countries. In the protocol-specified final overall survival (OS) analysis of MARIPOSA (NCT04487080), amivantamab-lazertinib showed a statistically significant and clinically meaningful improvement in OS versus osimertinib (HR, 0.75; P = 0.005) among all participants. We evaluated OS for amivantamab-lazertinib versus osimertinib in Asian participants.

Epidermal growth factor receptor (EGFR) exon 20 insertions (Ex20ins) are the third most common type of EGFR mutation, occurring in up to 12% of EGFR-mutated non-small cell lung cancers (NSCLC). Ex20ins-mutated NSCLC can be resistant to most approved tyrosine kinase inhibitors (TKIs). The Phase III PAPILLON trial (NCT04538664) demonstrated that amivantamab plus chemotherapy significantly improves progression-free survival (PFS) compared to chemotherapy alone, leading to its approval as a first-line treatment for patients with Ex20ins NSCLC. PAPILLON further evaluated patient-reported outcomes (PROs) and time to symptomatic progression (TTSP).

Amivantamab is a bispecific, epidermal growth factor receptor (EGFR) and MET-proto-oncogene (MET)-targeting antibody with immune cell-directing activity. In the global Phase 3 PAPILLON trial, amivantamab plus carboplatin-pemetrexed (amivantamab-chemotherapy) significantly improved progression-free survival (PFS) vs chemotherapy alone in previously untreated participants with locally advanced/metastatic NSCLC with EGFR exon 20 insertions (Ex20ins). We evaluated clinical outcomes in Asian participants in PAPILLON (NCT04538664).

We investigated whether circulating tumor DNA (ctDNA) changes may be useful to assess clinical outcomes in patients with metastatic colorectal cancer (mCRC) randomized in the TIME-PRODIGE-28 trial comparing biweekly maintenance with cetuximab alone with observation after 4-month fluorouracil, folinic acid, and irinotecan (FOLFIRI) plus cetuximab induction chemotherapy.

Clonal hematopoiesis (CH) is a precursor state linked to risk of hematologic neoplasms and may be exacerbated by radiation exposure. We aimed to compare CH prevalence after the new radioligand therapy 177Lu-PSMA-617 versus the alternative standard-of-care cabazitaxel chemotherapy in metastatic castration-resistant prostate cancer (mCRPC).

To determine the safety and efficacy of taselisib, a selective PI3K inhibitor, in combination with tamoxifen.

Inactivating vascular endothelial growth factor receptor (VEGFR) may improve the efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in EGFR-mutant non-small cell lung cancer (NSCLC). The ATTENTION study (phase II, open-label, randomized, multicenter trial (Registration number: ChiCTR2100047453), evaluated the efficacy and safety of aumolertinib plus apatinib vs. aumolertinib alone in untreated, EGFR-mutant, advanced NSCLC. The primary endpoint was the 18-month PFS rate. Across 18 centers in China, 104 patients were enrolled to receive aumolertinib alone (n = 51) or with apatinib (n = 53). At a median follow-up duration of 19.4 months, aumolertinib plus apatinib outperformed aumolertinib alone in terms of the 18-month progression-free survival (PFS) rate (74% vs. 50%, P = 0.036), median PFS (not reached [NR] vs. 20.1 months, hazard ratio [HR] = 0.41, P = 0.017), and objective response rate (79% vs. 59%, P = 0.024). No grade 4/5 treatment-related adverse effects (TRAEs) were observed, whereas grade 3 TRAEs occurred in 38% vs. 27% of patients, with hypertension (11%) and platelet count decrease (9%) being most common in the combination arm. Exploratory analysis revealed that PFS benefits from aumolertinib plus apatinib predominantly in those with TP53 mutations. As an infusion-free option, aumolertinib plus apatinib demonstrated PFS benefits with manageable safety in patients with untreated, EGFR-mutant, advanced NSCLC.

CPX-351 was approved for the treatment of acute myeloid leukemia (AML) using now-outdated definitions of AML with myelodysplasia-related changes (AML-MRC) and therapy-related AML. We evaluated whether the overall survival (OS) benefit of CPX-351 over standard cytarabine plus anthracycline (7+3) therapy is confined to molecularly defined AML subgroups by performing DNA sequencing in 184 patients enrolled in the pivotal phase 3 randomized trial. Patients were categorized hierarchically based on gene mutations: (1) TP53-AML, (2) DDX41-AML, (3) myelodysplasia-related AML (AML-MR) defined by the World Health Organization fifth edition criteria, or (4) other-AML. TP53-AML was subclassified as single (TP53single) or multihit (TP53multi) based on the number of alleles altered via mutation, deletion, or copy neutral loss of heterozygosity. Two-year OS differed significantly across molecular subgroups: TP53-AML (7%), AML-MR (19%), other-AML (37%), and DDX41-AML (70%) (P< .001). CPX-351 improved survival in patients with AML-MR compared with 7+3 (median, 9.7 vs 6.8 months; P = .037), with no benefit in TP53-AML or other-AML. For patients undergoing transplantation, CPX-351 improved 2-year survival (76% vs 27%; P< .01), an effect primarily observed in AML-MR. Multivariable analysis confirmed the independent association with survival of both CPX-351 and hematopoietic cell transplantation in AML-MR. TP53multi demonstrated significantly worse survival than TP53single (median, 3.8 vs 7.0 months; P = .004). The OS benefit of CPX-351 observed in the trial was driven by AML-MR with no benefit of CPX-351 in TP53-AML, in which the primary prognostic factor was allelic state. This trial was registered at www.clinicaltrials.gov as #NCT01696084.

The international PORTEC-4a trial demonstrated that individualised adjuvant treatment for women with (high)intermediate risk endometrial cancer (HIR-EC), guided by a molecular-integrated-risk-profile, achieves similar high local tumour control, while nearly half of patients were spared adjuvant treatment. Although determination of the molecular-integrated-profile increases diagnostics costs due to additional immunohistochemistry and DNA-sequencing, these costs may be offset by savings on other care and improved patient outcomes.

Detection of molecular residual disease using circulating tumor DNA (ctDNA) may enable postoperative risk stratification and guide adjuvant therapy. We evaluated the prognostic value of a tissue-free, epigenomic ctDNA assay in patients with stage III colon cancer (CC) enrolled in a phase III adjuvant chemotherapy trial.

Recurrence and metastasis significantly impact the survival outcomes of gastric cancer (GC) patients. Weifuchun (WFC), a well-established traditional Chinese medicine formulation, has been widely used in clinical practice for treating gastric disorders and as an adjunctive therapy following GC surgery.

A multicenter, randomized phase II trial to compare two first-line triplet treatments for advanced pancreatic ductal adenocarcinoma (PDAC).

The interim analysis of the JUPITER-06 study reveals significantly longer progression-free survival (PFS) and overall survival (OS) in advanced esophageal squamous-cell carcinoma (ESCC) patients treated with toripalimab in combination with paclitaxel (Taxol) plus cisplatin (TP). Prior work proposed copy number alteration-corrected tumor mutational burden (ccTMB) and an esophageal cancer genome-based immuno-oncology classification (EGIC) scheme as prespecified biomarkers to predict treatment efficacy. Here, we present the final analysis of the JUPITER-06 study and further explore potential biomarkers associated with OS.

Neoadjuvant chemotherapy (NCT) has been accepted as the standard management for locally advanced rectal cancer (LARC) without high-risk factors. However, many patients experience poor pathologic response, necessitating early-prediction tools. We investigated dynamic circulating tumor DNA (ctDNA) analysis for early response monitoring in patients with LARC undergoing NCT.

The phase 3 ENESTPath study investigated treatment-free remission (TFR) rates in patients with chronic Philadelphia chromosome-positive (Ph+) and/or BCR::ABL1+ chronic myeloid leukemia who had not achieved deep molecular response (DMR) after >2 years of imatinib treatment and were switched to nilotinib 300 mg twice daily (BID). After 24 months of treatment, patients with a stable DMR were randomized to either enter the TFR phase (Arm 1) or continue nilotinib consolidation for an additional 12 months and then enter the TFR phase if in stable DMR (Arm 2). The primary endpoint was the proportion of patients who remained in TFR (≥MR4.0 [BCR::ABL1IS ≤ 0.01%]) without molecular relapse at the end of 12 months. Of the 620 patients enrolled, 239 (38.5%) achieved stable MR4.0 and were randomized to Arm 1 (n = 120) or Arm 2 (n = 119). In the TFR phase, MR4.0 rates at 12 months (Arm 1: 31.9%, Arm 2: 37.5%; p = 0.383) and 24 months (Arm 1: 29.4%, Arm 2: 30.8%) revealed no differences in TFR success between 2 and 3 years of nilotinib. Irrespective of the consolidation duration, switching to nilotinib 300 mg BID provided the opportunity to achieve TFR if patients were unable to reach stable DMR with first-line imatinib.

In this phase 2 study (NCT05047991), patients with unresectable metastatic pancreatic adenocarcinoma were randomized to receive NALIRIFOX (liposomal irinotecan, 5-FU, leucovorin, and oxaliplatin) or gemcitabine plus nab-paclitaxel. The primary endpoint was progression free survival (PFS). Secondary endpoints included other efficacy outcomes (overall survival, objective response rate, disease control rate, and duration of response), as well as safety, pharmacokinetic parameters, and evaluation of the relationship between UGT1A1*6 and UGT1A1*28 polymorphisms and safety. A total of 117 patients were enrolled and randomly assigned to NALIRIFOX (n = 78) or gemcitabine plus nab-paclitaxel (n = 39). At a median follow-up of 18.7 months (interquartile range [IQR], 7.5-22.1) for NALIRIFOX and 12.1 months (IQR: 6.4-14.8) for the gemcitabine plus nab-paclitaxel, median PFS was 7.6 months (95% CI 5.52-9.23) with NALIRIFOX versus 3.7 months (95% CI 3.38-5.32) with gemcitabine plus nab-paclitaxel (hazard ratio, 0.56; 95% CI, 0.35-0.88; P = 0.0115). ≥ Grade 3 treatment-emergent adverse events (TEAEs) occurred in 73.1% of patients receiving NALIRIFOX and 84.6% of patients receiving gemcitabine plus nab-paclitaxel, respectively. Despite the premature termination (predetermined sample size of n = 153 not reached) of the study, NALIRIFOX demonstrated improvement in PFS compared with gemcitabine plus nab-paclitaxel, with a manageable safety profile in Chinese patients with advanced pancreatic adenocarcinoma.

Savolitinib combined with osimertinib is a potential novel therapy for patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC) harbouring MET amplification after progression on EGFR tyrosine kinase inhibitor (TKI) therapy. We aimed to evaluate the efficacy and safety of savolitinib-osimertinib versus standard of care platinum-based doublet chemotherapy in this patient population.

The MARIPOSA-2 study demonstrated improved progression-free survival with amivantamab and chemotherapy compared with chemotherapy alone in patients with EGFR-mutated locally advanced or metastatic non-small-cell lung cancer (NSCLC) with disease progression on or after treatment with osimertinib. This publication describes the results of patient-reported outcomes (PROs) measures and time to symptomatic progression (TTSP) for 2 treatment arms.
