Immunostimulatory effects of PARP inhibitors could increase sensitivity to immune checkpoint inhibitors. The previous Phase II trial (MEDIOLA) reported clinical benefits of durvalumab and olaparib (D + O) in patients with germline BRCA-mutated (gBRCAm) HER2-negative metastatic breast cancer. Yet, the clinical activity of D + O in germline BRCA wild-type (gBRCAwt) triple-negative breast cancer (TNBC) remains unknown.

Measurable residual disease (MRD) can predict relapse in patients with advanced myelodysplastic neoplasms (MDS) or acute myeloid leukemia (AML). We report the long-term efficacy and safety of MRD-guided preemptive azacitidine treatment to prevent relapse in the phase 2 Relapse Prevention With Azacitidine (RELAZA2) trial. Patients with MDS or AML after either intensive chemotherapy only or consecutive allogeneic stem cell transplantation were prospectively screened for imminent relapse by molecular MRD assessment. Patients who became MRD positive (MRDpos) during screening received azacitidine for up to 2 years to prevent relapse. The primary end point was the proportion of patients alive and relapse-free 6 months after azacitidine start. Of 357 patients screened, 119 (33.3%) became MRDpos, of whom 95 (79.8%) were eligible for azacitidine treatment. The primary end point was met; 60 (63%) patients were relapse free (95% confidence interval, 54-71; P< .0001) 6 months after azacitidine initiation with no new safety signals. Of 60 patients achieving MRD response during the first 6 cycles of azacitidine, 31 (52%) maintained response without hematological relapse for ≥2 years after azacitidine initiation. The median treatment-free duration after azacitidine discontinuation was 20.8 months; the longest ongoing response was 104 months. After a median follow-up of 6.6 years, 15 initial responders (25%) remained alive and in remission. Among screened patients who remained continuously MRD negative, 60-month overall survival and relapse-free survival were 88% and 79%, respectively. Patients with continuously negative MRD display a very favorable prognosis. Most patients with MRD positivity can be effectively treated with azacitidine with potential long-term remission even after termination of azacitidine. This trial was registered at www.clinicaltrials.gov as #NCT01462578.

Treatment of chronic lymphocytic leukemia (CLL) currently consists of two main approaches - continuous therapy with Bruton's tyrosine kinase inhibitors and fixed-duration regimens combining venetoclax with either CD20 antibodies or Bruton's tyrosine kinase inhibitors. Comparisons of these two therapeutic approaches are lacking.

Consolidation durvalumab following no progression on concurrent chemoradiotherapy (cCRT) is standard of care for unresectable stage III non-small-cell lung cancer (NSCLC). However, in clinical practice many patients receive sequential CRT (sCRT). The PACIFIC-5 trial aimed to evaluate the efficacy and safety of consolidation durvalumab for unresectable stage III NSCLC following no progression on cCRT or sCRT.

Mismatch repair-deficient (dMMR) colorectal cancer (CRC) is characterized by poor response to traditional chemotherapy but heightened sensitivity to immune checkpoint inhibitors (ICIs). However, it is unclear whether envafolimab, a subcutaneous programmed death-ligand 1 inhibitor, provides comparable efficacy and safety as a neoadjuvant treatment in these patients compared to programmed cell death-1 inhibitors.

Ceralasertib is an oral, selective, and potent inhibitor of ATR serine/threonine kinase, a key protein involved in cell cycle checkpoint regulation and DNA damage response. We report preliminary safety, tolerability, and pharmacokinetic data of ceralasertib monotherapy in Japanese patients with advanced solid tumors.

Cholangiocarcinoma is a rare, aggressive cancer often driven by FGFR2 fusions, which are targetable with inhibitors such as pemigatinib and futibatinib. However, resistance frequently develops due to acquired FGFR2 mutations. In this study, we aimed to evaluate the efficacy and safety of tinengotinib in previously treated patients with advanced cholangiocarcinoma.

TOURMALINE-MM3 (NCT02181413) and -MM4 (NCT02312258) were phase 3 studies of fixed-duration, single-agent ixazomib maintenance in post-transplant (TOURMALINE-MM3)/transplant-ineligible (TOURMALINE-MM4) patients with newly diagnosed multiple myeloma (NDMM) that demonstrated improved median progression-free survival (PFS) for ixazomib vs placebo. We present the final overall survival (OS) analyses for each study separately. In both studies, eligible patients were randomized 3:2 to receive ixazomib maintenance (3 mg [cycles 1-4], 4 mg [from cycle 5 if tolerated]) or matching placebo for ≤26 cycles, or until progressive disease/unacceptable toxicity. At median follow-up of approximately 8 years (TOURMALINE-MM3) and 5 years (TOURMALINE-MM4), median OS was not reached in either arm in MM3 (hazard ratio [HR], 1.025; 95% confidence interval [CI], 0.789-1.332; p = 0.850), and was 64.8 (ixazomib) vs 69.5 (placebo) months in MM4 (HR, 1.090; 95% CI, 0.861-1.381; p = 0.473). No new safety signals were identified in either study; incidence of new primary malignancies was low. Despite meeting their primary endpoints (PFS), neither final OS analysis of TOURMALINE-MM3/-MM4 showed statistically significant differences between fixed-duration ixazomib maintenance and placebo in patients with NDMM. The growing number of available, highly effective salvage treatments with novel mechanisms of action make demonstrating an OS advantage in front-line myeloma studies increasingly challenging.

Salivary gland cancer (SGC) is rare and has various histological types. This rarity and heterogeneity have hindered elucidation of the therapeutic contribution of systemic therapy, including immune checkpoint inhibitors, to recurrent or metastatic SGC (RM-SGC). The purpose of this trial was to investigate the efficacy and safety of nivolumab for platinum-refractory RM-SGC.

The adenosinergic pathway represents a critical immunometabolic checkpoint within the tumor microenvironment of non-small cell lung cancer (NSCLC), contributing to immune suppression and therapeutic resistance. PBF-1129, an oral, selective A2B adenosine receptor (A2BAR) antagonist, was evaluated in a phase 1, open-label, dose-escalation trial (NCT03274479) in patients with advanced/metastatic NSCLC who had progressed on standard therapies. All patients had previously received chemotherapy and immune checkpoint blockade. Twenty-one patients received escalating doses (40-320 mg once daily), with no dose-limiting toxicities observed. The most frequently reported treatment related adverse events of any grade were lymphocytopenia (n = 8, 38.1%), vomiting (n = 8, 38.1%), anorexia (n = 6, 28.5%), and fatigue (n = 6, 28.5%). PBF-1129 showed dose-proportional pharmacokinetics and maintained plasma concentrations above the 90% maximal inhibitory concentration (IC90) of A2BAR at 320 mg for 24 h, which was determined to be the recommended phase 2 dose (RP2D). Best response was stable disease in 3 out of 21 patients including 2 of 6 treated at RP2D. Immunophenotyping revealed post-treatment reductions in programmed cell death protein 1 (PD-1) expression on CD8⁺ T cells, which correlated with improved survival. The reduction of PD-1 expression on CD4⁺ T cells and decreased myeloid-derived suppressor cells were also associated with better outcomes. These findings suggest PBF-1129 is safe and modulates the systemic immune parameters, warranting further evaluation in combination with immune checkpoint blockade.

Programmed cell death protein-1 (PD-1) blockade has shown promising clinical efficacy in hepatocellular carcinoma (HCC), yet the underlying immunological mechanisms governing response and resistance remain unclear. This study aimed to delineate the temporal and spatial dynamics of T-cell clonotypes and their relationship with pathological response in neoadjuvant PD-1 blockade therapy in HCC. By integrating T-cell receptor (TCR) repertoire analysis with transcriptomic profiling, we sought to elucidate the immune landscape alterations associated with treatment outcomes.

Metastatic pheochromocytoma and paraganglioma (MPP) currently lack definitive curative therapies. The treatment of MPP presents a formidable challenge. Anlotinib hydrochloride, characterized as a multi-targeted tyrosine kinase receptor inhibitor, has demonstrated potential in this domain. This study, a phase 2 trial (NCT04860700), aimed to evaluate the efficacy and safety profiles of anlotinib hydrochloride in patients suffering from MPP. The primary objective was to determine the disease control rate (DCR) and objective response rate (ORR) as determined by the RECIST 1.1 criteria. Secondary objectives were to evaluate the biochemical response, progression-free survival (PFS), and safety. Twenty-nine patients with MPP were enrolled. We found that 24.1% (7/29) of patients discontinued the treatment after 1-2 cycles because of a significant increase in hormone levels or adverse events. Among 22 patients who could be evaluated by the RECIST 1.1 criteria, the overall DCR was 95.5% (21/22), and the ORR was 31.8% (7/22). The PFS was calculated to be 22.6 ± 3.2 months. There is no significant difference in ORR or PFS between patients with and without germline mutations. The most common adverse events included arterial hypertension (24/29, 82.8%), subclinical primary hypothyroidism (11/29, 37.9%), hyperlipidemia (10/29, 34.5%), rash (8/29, 27.6%), and fatigue (8/29, 27.6%). We conclude that among the evaluable patients, anlotinib showed promising efficacy with high DCR. Close monitoring remains essential because of treatment-related adverse events.

SG001 is a humanized, IgG4 monoclonal antibody against human PD-1. This phase 1b study aimed to evaluate efficacy and safety of SG001 in advanced solid tumors.

Aims of this first-in-human clinical trial were to evaluate the safety and efficacy of sonodynamic therapy (SDT) using a newly developed trigger pulse high-intensity focused ultrasound (HIFU) device, MS-2, and micellar nanoparticle-encapsulated epirubicin, K-912, in patients with unresectable refractory abdominal cancers.

Several menin inhibitors are in development targeting menin dependent leukemias, however available preclinical results show variable level of activity. We report the phase 1 portion (to establish a recommended phase 2 dose [RP2D]) and pharmacokinetic analysis of a phase 1/2 first-in-human clinical trial of DS-1594b menin inhibitor. Eligible patients included adults (≥ 18 years of age) with relapsed/refractory (R/R) acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) including but not restricted to those with KMT2A-rearrangement (r) or NPM1 mutation. Seventeen patients at a median of age 56 years (range, 19-82 years) were treated, 15 (88%) had R/R AML, and 2 (12%) had R/R B-ALL; 9 (53%) had a KMT2A-r but none had an NPM1 mutation. The median prior lines of therapy was 3 (range 1-8) and 5 patients (29%) had received prior menin inhibitors. Five dose escalation cohorts were evaluated; no RP2D was established, and the trial was stopped at phase 1 due to a decision by supporting company due to lack of efficacy at studied dose levels and portfolio realignment. Differentiation syndrome (DS) was seen in 5 patients (29%); 2 in cohort 1 (70 mg twice daily, n = 4) 1 each had grade 1 and grade 4 DS, 3 patients in cohort 2 (50 mg twice daily/100 mg daily, n = 4) of whom 2 had grade 2 and 1 patient had grade 3 DS (considered as dose limiting toxicity). No DS was noted at cohort 3 (20 mg/day), and in subsequent dose-escalation cohorts (cohorts 4 and 5) a lead-in ramp-up dosing starting at 20 mg/day was instituted to improve tolerability. Other relevant treatment emergent adverse events of grade ≥ 3 included infections; pneumonia and febrile neutropenia in 7 patients each (41%), and sepsis in 6 patients (35%). No study drug related deaths were noted. No patient achieved a response, however 4 patients (23%) had > 25% bone marrow blast reduction. Pharmacokinetic analysis showed DS-1594b reached maximum concentration approximately in 2 h with total exposure increasing with escalating doses and reached stead-state by Cycle 1 Day 8. DS-1594b showed limited efficacy at the doses tested but appeared safe with a lead-in dosing approach.

Brain-infiltrating tumour cells from high-grade glioma remain shielded from drug treatments by the blood-brain barrier, leading to inevitable recurrence. Microbubble-enhanced transcranial focused ultrasound (MB-FUS) enables controlled blood-brain barrier opening (BBBO), permitting localised drug delivery. We aimed to assess safety and feasibility of MB-FUS plus standard-of-care chemotherapy for individuals with high-grade glioma.

In the primary report of the SYSUCC-001 trial, 1 year of metronomic capecitabine improved 5-year disease-free survival in patients with operable triple-negative breast cancer. Here, we provide updated 10-year disease-free survival and overall survival data from extended follow-up, together with an exploratory analysis of FOXC1 as a potential predictive biomarker.

Addition of anti-angiogenic inhibitors has the potential to enhance the efficacy of poly(ADP-ribose) polymerase (PARP) inhibitors; however, clinical evidence for their use in breast cancer is scarce. The FABULOUS study assessed fuzuloparib (an oral PARP inhibitor) with or without apatinib (an oral angiogenesis inhibitor) for breast cancer.

This study was designed as a randomized controlled trial (RCT) with a pretest-posttest design to investigate the effects of mandala art therapy on nausea, vomiting, pain, and anxiety in children and youth undergoing outpatient chemotherapy.

Fimepinostat, an oral dual inhibitor of histone deacetylase (HDAC) and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K), has shown activity in preclinical models of Myc-driven pediatric malignancies. This Phase 1 trial aimed to determine the recommended pediatric Phase 2 dose (RPP2D), describe the toxicity profile, and evaluate the pharmacokinetics of fimepinostat in children with relapsed and refractory solid and central nervous system (CNS) tumors.
