PARP inhibitors have attracted considerable interest in drug discovery due to the clinical success of first-generation agents such as olaparib, niraparib, rucaparib, and talazoparib. Their success lies in their ability to trap PARP to DNA; however, first-generation PARP inhibitors were not strictly optimized for trapping nor for selectivity among the PARP enzyme family. Previously we described the discovery of the second-generation PARP inhibitor AZD5305, a selective PARP1-DNA trapper.

Background: Poly (ADP-ribose) polymerase 1 and 2 (PARP1/2) inhibitors (PARPi) are targeted therapies approved for homologous recombination repair (HRR)-deficient breast, ovarian, pancreatic, and prostate cancers. Since inhibition of PARP1 is sufficient to cause synthetic lethality in tumors with homologous recombination deficiency (HRD), PARP1 selective inhibitors such as saruparib (AZD5305) are being developed. It is expected that selective PARP1 inhibition leads to a safer profile that facilitates its combination with other DNA damage repair inhibitors.

Introduction: Antibiotic resistance poses a significant threat to public health, that can lead to reduced effectiveness of many therapies, increased morbidity, longer hospitalization times, increased deaths, and additional costs for health care systems. Unreasonable use of antibiotics may result from a lack of adequate knowledge about antibiotic therapy and a lack of knowledge of the risks associated with antibiotic resistance, both among medical personnel and patients.

Aim: The primary objective of the study was to verify the opinion of medical personnel on the risks associated with antibiotic resistance.

Article Synopsis
  • The study focuses on optimizing dosages for radiotherapy (RT) combined with immune checkpoint blockade (ICB) and DNA Damage Response inhibitors (DDRi) to enhance treatment effectiveness and reduce toxicity.
  • It introduces a mathematical model that analyzes how RT can boost the immune response, particularly through increasing cytolytic T cells targeting tumors and how DDR inhibitors can delay T cell exhaustion.
  • Results show that while the combo of RT and anti-PD-L1 is most effective, decreasing anti-PD-L1 efficacy slightly could make the ATM inhibitor AZD0156 more beneficial in tri-therapy scenarios.

Clinical trials assessing the impact of radiotherapy (RT) in combination with DNA damage response pathway inhibitors (DDRis) and/or immune checkpoint blockade are currently ongoing. However, current methods for optimizing dosage and schedule are limited. A mathematical model was developed to capture the impacts of RT in combination with DDRi and/or anti-PD-L1 [immune checkpoint inhibitor (ICI)] on tumor immune interactions in the MC38 syngeneic tumor model.

Unlabelled: PARP inhibitors (PARPi) have changed the management of patients with ovarian cancer and their effectiveness has been demonstrated especially in homologous recombination repair-deficient tumors. These first-generation drugs target PARP1, but also PARP2 and other family members potentially responsible for adverse effects that limit their therapeutic potential and restrict their use in combination with chemotherapeutic agents. We investigated ovarian cancer patient-derived xenografts (OC-PDXs) to assess whether malignant progression could be impaired by a novel inhibitor selective for PARP1 (AZD5305) and to assess the potential of its combination with carboplatin (CPT), the standard-of-care for patients with ovarian cancer.

Purpose: We evaluated the activity of AZD8205, a B7-H4-directed antibody-drug conjugate (ADC) bearing a novel topoisomerase I inhibitor (TOP1i) payload, alone and in combination with the PARP1-selective inhibitor AZD5305, in preclinical models.

Experimental Design: IHC and deep-learning-based image analysis algorithms were used to assess prevalence and intratumoral heterogeneity of B7-H4 expression in human tumors. Several TOP1i-ADCs, prepared with Val-Ala or Gly-Gly-Phe-Gly peptide linkers, with or without a PEG8 spacer, were compared in biophysical, in vivo efficacy, and rat toxicology studies.

Article Synopsis
  • - The PI3K-AKT pathway is often active in breast cancer, and inhibitors targeting this pathway, like capivasertib and AZD8186, are used in treatments, but the reasons for resistance to these therapies aren't well understood on a broad scale.
  • - CRISPR screenings identified key genes that lead to treatment resistance, revealing that reactivation of PI3K-AKT-mTOR signaling is the primary mechanism, while deletion of certain genes can either confer resistance or increase sensitivity to these drugs.
  • - Loss of Mcl-1 enhances the effectiveness of PI3K-AKT inhibitors by promoting faster cell death, and combining Mcl-1 inhibitors with PI3K-AKT inhibitors shows promise for overcoming resistance in various breast

Purpose: We hypothesized that inhibition and trapping of PARP1 alone would be sufficient to achieve antitumor activity. In particular, we aimed to achieve selectivity over PARP2, which has been shown to play a role in the survival of hematopoietic/stem progenitor cells in animal models. We developed AZD5305 with the aim of achieving improved clinical efficacy and wider therapeutic window.

Article Synopsis
  • PARP inhibitors, like olaparib, cause cell death in cancer cells with BRCA1/2 mutations by leading to DNA damage, which can also trigger an immune response against tumors.
  • When olaparib is combined with immune checkpoint blockade (ICB), it showed enhanced and longer-lasting anti-tumor effects compared to using either treatment alone in a specific mouse model.
  • The combination therapy not only boosted the number of active immune cells but also activated important immune signaling pathways, and these findings were supported by results from human patient samples, indicating a promising direction for enhancing cancer treatment strategies.

An increasing body of evidence from both academic and clinical studies shows that time-of-day exposure to antigens might significantly alter and modulate the development of adaptive immune responses. Considering the immense impact of the COVID-19 pandemic on global health and the diminished efficacy of vaccination in selected populations, such as older and immunocompromised patients, it is critical to search for the most optimal conditions for mounting immune responses against SARS-CoV-2. Hence, we conducted an observational study on 435 healthy young adults vaccinated with two doses of BNT162b2 (Pfizer-BioNTech) vaccine to determine whether time-of-day of vaccination influences either the magnitude of humoral response or number of adverse drug reactions (ADR) being reported.

Poly-ADP-ribose-polymerase (PARP) inhibitors have achieved regulatory approval in oncology for homologous recombination repair deficient tumors including BRCA mutation. However, some have failed in combination with first-line chemotherapies, usually due to overlapping hematological toxicities. Currently approved PARP inhibitors lack selectivity for PARP1 over PARP2 and some other 16 PARP family members, and we hypothesized that this could contribute to toxicity.

Alterations in KRAS have been identified as the most recurring somatic variants in the multiple myeloma (MM) mutational landscape. Combining DNA and RNA sequencing, we studied 756 patients and observed KRAS as the most frequently mutated gene in patients at diagnosis; in addition, we demonstrated the persistence or de novo occurrence of the KRAS aberration at disease relapse. Small-molecule inhibitors targeting KRAS have been developed; however, they are selective for tumors carrying the KRASG12C mutation.
