This is a multi-center, first-in-human (FIH), open-label, Phase 1a/1b dose escalation and dose expansion study to assess the safety, PK, pharmacodynamics, and antitumor activity of PHST001 monotherapy (Phase 1a) or in combination with chemotherapy (Phase 1b) in adult participants with advanced relapsed and/or refractory solid tumors (including but not limited to CNS tumors in Phase 1a only). In Phase 1b cohort expansions, the study will focus on participants with advanced relapsed and/or refractory ovarian cancer, endometrial cancer, and cholangiocarcinoma. The study's primary objective is to evaluate the safety and tolerability of PHST001 and determine the RP2D (Recommended Phase 2 dose) of PHST001 monotherapy and in combination with chemotherapy as well as assess the anti-tumor activity of PHST001 and chemotherapy in Phase 1b.

Optimal Timing of Surgery combined with Maintenance Therapy in the Front-line Treatment of Advanced Ovarian Cancer

The goal of this prospective observational study is to evaluate the role of ultrasound-guided tru-cut biopsy (in the hands of an expert certified sonographer within a gynecological center)in patients with suspected ovarian cancer. The main questions it aims to answer are: Is the material from tru-cut biopsy adequate for histopathological and immunohistochemical examination? Is the material accurate in comparison with the final pathological specimen? What are the patient experience and complications after the procedure? Participants who will undergo a standard tru-cut biopsy procedure will need to additionally answer the questionnaire.

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.

This study, the first clinical trial of AVZO-021, aims to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, maximum tolerated dose, and anti-tumor effects of AVZO-021 in patients with advanced solid tumors. AVZO-021 is an oral medication that inhibits cyclin-dependent kinase 2 (CDK 2).

This is a study to evaluate the safety and potential anti-tumor activity of an investigational agent called ARV-806 in Adults with Advanced Cancer having a specific KRAS mutation. This is an open-label study which means that participants and study staff will know that all participants will receive ARV-806. Researchers think that ARV-806 can work by breaking down a specific protein with a mutation that is present in some tumors, which might help prevent or slow tumors from growing. This will be the first time ARV-806 will be used in people. The investigational drug will be given through a vein. This is called intravenous (IV) infusion. This study will include 2 parts. In Part A (Phase 1), different small groups of participants will receive lower to higher doses of ARV-806. Adults with advanced cancers having a specific KRAS mutation will be included. In Part B (Phase 2), participants will be assigned to receive one of up to 2 dose levels decided by the information from Part A. Part B will include participants with advanced pancreatic ductal cancer having a specific KRAS mutation.

Genetic testing can alter therapy and surgical management for cancer patients and is therefore indicated as a first-line test for many newly diagnosed patients, including breast, ovarian, pancreatic, prostate and colon/GI patients. To reduce pressure on already constrained genetics clinics across Canada, some cancer centres are 'mainstreaming' genetic testing - whereby genetic testing is initiated and mediated by oncologists without traditional pre-test genetic counseling (GC) often using some form of paper-based patient pamphlets or videos. There is no standard, evidence-based approach to mainstreaming, leading to significant practice variation, a lack of coordinated care and ultimately, negative psychological impacts on patients. Digital solutions can address these gaps by providing a standardized, coordinated and patient-centered approach to deliver cancer genetic education. However, digital solutions for providing cancer genetics services are uncommon and clinical-effectiveness and service delivery outcomes have not been well-assessed. This study will test a digital mainstreaming platform called the Genetics Adviser for Mainstream care to assess its effectiveness in improving psychological outcomes and patient-centred care for mainstream cancer patients compared to standard of care.

The goal of this clinical trial is to see if timed fasting (periods of time that you don't eat) in participants who are receiving chemotherapy prior to surgery is achievable, safe and can improve quality of life, symptoms and outcomes (results) compared to participants who receive standard dietary recommendations in individuals being treated for epithelial ovarian cancer . The main questions it aims to answer are: * Is it feasible to use intermittent fasting during neoadjuvant chemotherapy? * Is it safe to use intermittent fasting during neoadjuvant chemotherapy? * Do participants find it acceptable to use intermittent fasting during neoadjuvant chemotherapy? Researchers will compare participants who receive standard dietary recommendations to see which method is more achievable, safe, and able to improve quality of life, symptoms and outcomes. Participants will: * Receive either the fasting intervention (schedule of times when you do not eat) or standard diet recommendations for 6-9 weeks prior to your surgery starting with the second cycle of chemotherapy. * All participants will be asked to complete chemotherapy and surgery, cancer imaging, baseline screening tests, nutritional assessments, food diaries, blood tests, and surveys about wellbeing. * Participants in the intervention group will be asked to follow a fasting schedule that consists of not eating for 16 hours a day followed by normal eating for the remaining 8 hours of the day for 5 days in a row followed by 2 days of regular eating each week.

This study will investigate whether the addition of Quercetin or Alpha-Lipoic Acid (ALA) to standard metformin therapy can improve symptoms, hormone levels, metabolic health, and quality of life in women with polycystic ovary syndrome (PCOS). Over 3 months, participants will be randomly assigned to one of three groups: metformin alone, metformin plus Quercetin, or metformin plus ALA. Researchers will measure changes in hormones, blood sugar, cholesterol, and antioxidant markers, as well as quality of life and medication adherence. Physical measurements and side effects will also be recorded to assess safety and overall benefit.

Background: Previous findings have indicated antineoplastic properties of tinzaparin (Innohep®), a commonly used anti-coagulant. Earlier studies have mainly investigated the antineoplastic effects of tinzaparin in animal models and in human cell-lines. In this pilot study the aim is to examine the potential antitumoral effects of tinzaparin in vivo in women with epithelial ovarian cancer (EOC). Study objectives: Primary objective: The primary objective of the study is to evaluate the effects of tinzaparin on changes in levels of CA-125 in EOC patients who receive neoadjuvant chemotherapy (NACT). Secondary objectives: The secondary objective of the study is to explore the impact of tinzaparin on the dynamic of a spectrum of immunological and coagulation factors in EOC patients who receive NACT. Besides, the compliance of tinzaparin injections and adverse events caused by tinzaparin will be described.

This observational study is to better understand how children and their families recover after the stress of major surgery for cancer so that investigators can create ways to improve resilience during recovery. The main questions it aims to answer are: 1. Can information obtained from patients and their caregivers wearing smartwatches and answering questionnaires be used to measure how patients are recovering from surgery? 2. Are there specific patterns in patients' circulating proteins and metabolites that are associated with stress after surgery? Participants, including pediatric patients undergoing surgery for cancer and their primary caregiver, will be asked to: * wear a smartwatch * complete questionnaires * allow for extra blood to be drawn for this research study when they are having their regular blood draws for clinical purposes These actions will occur at baseline prior to patients' surgery and then afterwards for up to one year. There are no changes to participants' clinical care or surgical care as a result of the study. Investigators will also collect participants' clinical information and cancer-specific outcomes. Participants will be remunerated for their time.

The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and cell-free RNA (cfRNA), are non-invasive, real-time biomarkers that can provide diagnostic and prognostic information before cancer diagnosis, during cancer treatment, and at disease progression. Cancer research scientists and clinicians at the Princess Margaret are interested in incorporating the collection of peripheral blood samples ("liquid biopsies") into research protocols as a means of non-invasively assessing tumor progression and response to treatment at multiple time points during a patient's course of disease.

This is a combined prospective and retrospective observational study aiming to validate a highly sensitive and specific blood-based method for the early diagnosis and post-treatment monitoring of multiple cancers. The study leverages a newly developed sequencing method to improve the detection of circulating tumor DNA (ctDNA) in blood, focusing on enhancing sensitivity and specificity in clinical applications. The study targets patients with ovarian, lung, pancreatic, colorectal, esophageal, breast, kidney, bladder, and gastric cancer, as well as healthy controls with asymptomatic gallstones, benign polyps, or individuals undergoing routine medical screening. Blood samples will be analyzed for cell-free DNA (cfDNA), RNA, and protein profiles. A key objective is to determine how much the newly developed method increases the sensitivity and specificity of ctDNA detection, especially in early-stage cancers and minimal residual disease (MRD) after treatment. The method evaluates the variant allele frequency (VAF) of ctDNA to detect residual disease and track tumor dynamics. Serial blood sampling will be conducted before and after surgery or chemotherapy and during follow-up outpatient visits in cancer patients, while one-time sampling will be done for controls. Additionally, tissue biopsies collected during surgery will be used to analyze concordance between tumor-specific mutations and those found in ctDNA. Primary outcome measures include quantitative differences in ctDNA or RNA levels between cancer and control groups. Secondary outcomes assess the clinical correlation between changes in ctDNA VAF and patient outcomes such as recurrence and survival. Statistical tools including ROC curve analysis, Cox regression, and log-rank tests will be used to quantify performance. This study seeks to establish a clinically robust, non-invasive diagnostic tool that enables earlier detection and more precise treatment decisions, while potentially reducing physical, psychological, and socioeconomic burdens related to cancer care.

This clinical trial compares the effect of an automated personalized physical activity intervention supported by wearable technology to standard of care on physical activity levels and quality of life in patients with stage II- IV ovarian, primary peritoneal, fallopian tube cancer or endometrial cancer that is newly diagnosed. Physical activity is a modifiable risk factor for the prevention and treatment of many diseases. In fact, increased levels of physical activity have been shown to decrease the risk of some cancers as well as increase overall survival in some cancers. Currently, standard of care guidelines include participation in at least 150 minutes of moderate exercise weekly. An automated personalized physical activity intervention may increase physical activity, enhance quality of life, and improve physical function and daily living activities compared to standard recommendations in patients with stage II-IV ovarian, primary peritoneal, fallopian tube or newly diagnosed endometrial cancer. This trial also evaluates the impact of physical activity on the gut microbiome and immune function. The microbiome is the collection of tiny organisms, like bacteria, that live in and on the body, especially places like the gut. These microorganisms play an important role in health. Information gathered from this study may help understand how the gut microbiome and physical activity influences the immune system in patients with stage II-IV ovarian, primary peritoneal, fallopian tube or newly diagnosed endometrial cancer.

About 70% of epithelial ovarian cancer patients are diagnosed at advanced stage. When primary optimal surgery is not possible, neoadjuvant chemotherapy will followed by interval debulking surgery is one treatment option. However, there is no consensus on the optimal timing of the surgery. CA125 is a well-known tumor marker in ovarian cancer. Its kinetic change has been proven to correlate with the patients' response to chemotherapy and chance of optimal resection. This study aims to utilize the kinetic change of CA125 to customize the timing of surgery for individual patients.

To find the highest tolerable dose of IACS-6274 that can be given alone, in combination with bevacizumab and paclitaxel, or in combination with capivasertib to patients who have solid tumors. The safety and tolerability of the study drug(s) will also be studied.

This is a randomized, double-blind, placebo-controlled,parallel-group preliminary verifying study about safety and efficacy of maintenance DCVAC/OvCa after first-line chemotherapy added to standard of care in patients with newly diagnosed FIGO III-IV ovarian, fallopian tube, or primary peritoneal carcinoma.

This Phase 1/2 study evaluates the safety, tolerability, and preliminary anti-tumor activity of dual-targeting chimeric antigen receptor natural killer (CAR-NK) cells in participants with recurrent or refractory epithelial ovarian, primary peritoneal, or fallopian tube cancer. At screening, each participant's tumor is assessed for expression of Mesothelin (MSLN), Folate Receptor alpha (FRalpha/FOLR1), and MUC16 (CA 125). Participants are assigned to the dual-target CAR-NK product that best matches their tumor antigen profile to reduce the risk of antigen escape.
