An Open-label, First-in-Human, Dose-Escalation and Dose-Expansion Phase I/II Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SPR1020 in Patients With Advanced Solid Tumors

This study is a multicenter, open-label study designed to evaluate SPR1020 in adult patients with advanced solid tumors. The study aims to characterize the safety, tolerability, pharmacokinetic (PK) profile, and preliminary antitumor activity of SPR1020 monotherapy in this population. The study consists of two parts: Phase I component (dose escalation and backfill) and Phase II component (dose expansion). The primary objectives of the Phase I part are to investigate the safety, tolerability, and PK profile of SPR1020 and to determine the Recommended Phase II Dose (RP2D) and/or the Maximum Tolerated Dose (MTD), if attainable. The Phase II part will be initiated once the RP2D and/or MTD is established in the Phase I part. As a new-generation, highly selective PARP1 inhibitor, SPR1020 demonstrates a competitive clinical benefit-risk profile, combining potential intracranial activity with a differentiated safety profile. By leveraging a "synthetic lethality" mechanism, SPR1020 is expected to demonstrate significant efficacy against tumors harboring BRCA mutations or homologous recombination repair (HRR) pathway gene alterations (e.g., breast cancer, prostate cancer). Owing to its high selectivity for PARP1 over PARP2, SPR1020 may circumvent the hematological toxicities associated with PARP2 inhibition by first-generation pan-PARP inhibitors (e.g., olaparib), potentially resulting in an improved safety profile. This enhanced safety may provide greater flexibility for use in combination therapies. Furthermore, SPR1020's ability to penetrate the blood-brain barrier could offer a new treatment option for patients with advanced disease and brain metastases, addressing a high unmet medical need in this population with limited therapeutic choices. Preclinical data support this differentiated profile in terms of both efficacy and toxicity. Hypothesis: SPR1020 represents a novel anticancer therapeutic with the potential for enhanced efficacy and an improved safety profile. The overall assessment indicates that its clinical benefits outweigh the potential risks. This study has been approved by the IEC and adheres to the principles of the Declaration of Helsinki.

The HER Project: HRD in EGFR-mutated NSCLC

This observational retrospective-prospective study aims to evaluate the prevalence of homologous recombination deficiency (HRD) in metastatic EGFR mutated NSCLC and to assess its correlation with clinical and molecular features. Based on the hypothesis that HRD identifies a distinct EGFRm subgroup with prognostic value and a potential sensitivity to PARP inhibitor-based strategies, translational analysis will be performed with multiple pre-clinical models, ranging from human cancer cells to murine models.

REVITALIZE: RCT to Reduce Fatigue in Adults With Ovarian Cancer on PARP Inhibitors

The purpose of this study is to see whether a supportive intervention (REVITALIZE) reduces fatigue and its impact on daily life and activities for participants with ovarian cancer taking PARP inhibitors. The name of the study groups in this research study are: 1. REVITALIZE 2. Educational Materials

Phase I/IIa Study of Concomitant Radiotherapy With Olaparib and Temozolomide in Unresectable High Grade Gliomas Patients

The Stupp protocol is the standard treatment of glioblastoma multiform (GBM) which prognosis remains poor. The non-dividing nature of normal brain cells provides an opportunity to enhance the therapeutic ratio by combining radiation with inhibitors of replication-specific DNA repair pathways such poly(ADP-ribose) polymerase (PARP) inhibitors, thus inducing more cytotoxic effects of DNA-damage related to treatment modalities, including alkylating reagents like temozolomide (TMZ). Olaparib, a potent PARP inhibitor, overcomes apoptotic resistance and sensitizes GBM cells for death receptor-mediated apoptosis induced by TRAIL (Tumor necrosis factor-Related Apoptosis Inducing Ligand). Moreover, inhibition of PARP activity increases cellular sensitivity to ionizing radiation: it was even suggested to be more pronounced in tumors than in normal tissue. Lastly, progress in technical imaging and intensity-modulated-radiotherapy (IMRT) techniques provide new possibilities for sparing healthy tissues.

Vismodegib Combined With Atezolizumab in Platinum Resistant Ovarian, Fallopian Tube, and Primary Peritoneal Cancer

This trial will treat patients with platinum resistant ovarian, fallopian tube or primary peritoneal cancer as defined by a progression free interval within six months of completion of most recent platinum-based treatment with a combination of vismodegib and atezolizumab. Despite recent improvements in treatment of ovarian cancer with the introduction of PARP inhibitors, response rates to therapy in the platinum resistant setting remain dismal with response rates of only 10-20% reported for single agent cytotoxic therapies. Given the poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates.

PARPi and Ovarian Cancer Survival

With the widespread use of PARP inhibitors (PARPi) as maintenance therapy in ovarian cancer, there is still a lack of real-world data from large samples regarding their impact on survival outcomes in advanced and recurrent ovarian cancer. This study aims to conduct a pragmatic cohort study to evaluate the impact of first-line and second-line maintenance treatment with PARPi on survival rates in patients with advanced and recurrent ovarian cancer. The genetic status, different PARPi drugs, and the use of anti-angiogenic inhibitor maintenance therapy or not is used as confounding factors.

Safety Assessment of Concurrent Radiotherapy and Novel Systemic Therapy for Breast Cancer

Radiation therapy is a crucial part in the comprehensive treatment of breast cancer. In recent years, emerging systemic treatment regimens such as HER 2 inhibitors, CDK 4/6 inhibitors, PARP inhibitors, capecitabine and PD1 inhibitors have greatly improved the prognosis of breast cancer and has become the standard treatment for specific populations. A considerable number of patients require both radiotherapy and maintenance systemic therapy. However, it is not clear whether systemic therapy should be synchronized or suspended in radiotherapy，despite that previous basic research shows that some molecular drug therapy and radiotherapy has a clear synergy mechanism. There is an agent need for a definite evidence to evaluate the safety of synchronous treatment, to support clinical diagnosis and treatment and the next step of comprehensive treatment. The implementation of the new radiotherapy technology represented by IMRT takes into account the prescription dose homogenization and the minimization of normal tissue dosage, which provides a certain basis for the combination therapy. Based on the above conditions, this study intends to enroll patients between 18 and 70 years old with chest wall / breast ± lymphatic drainage area and requiring capecitabine, CDK 4/ 6 inhibitor, HER2 targeted therapy or immunotherapy. Radiation and novel systemic therapies would be delivered concurrently. The study aimed at evaluating the safety of combined treatments.
