Researchers are evaluating a culturally-tailored, home-based physical activity program designed to improve physical fitness in Hispanic or Latino/Latina adolescent and young adult childhood cancer survivors. These survivors may face long-term effects such as weight gain, fatigue, and reduced fitness after cancer treatment, with Hispanic or Latino/Latina individuals potentially at higher risk. The study aims to increase moderate to vigorous physical activity (MVPA) through a mobile health and social media intervention. The study has two stages. Stage 1 involves developing the intervention using feedback from 20 Latinx survivors who speak either English or Spanish. Stage 2 is a randomized controlled trial comparing the intervention group with a control group that only uses a Fitbit tracker. The intervention group receives Fitbit trackers, weekly reminders, goal-setting sessions, social media peer support 2-3 times a week, badges, monthly Zoom meetings, and may choose a physical activity partner who also receives support. After 12 weeks, a 4-week maintenance phase continues these supports with less structure. The control group wears a Fitbit daily for 12 weeks without additional support. Participants wear Fitbit trackers daily, attend weekly sessions, post on social media, and complete interviews and questionnaires. Researchers measure changes in physical activity levels, sedentary time, quality of life, and cardiometabolic health indicators. Data is collected using Fitbit devices, interviews, and surveys, with follow-up over 12 weeks plus maintenance. Safety and acceptability of the intervention are also assessed throughout the study.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.

The trial investigates the use of volrustomig in participants with unresected locally advanced head and neck squamous cell carcinoma (LA-HNSCC) who have not shown disease progression after receiving definitive concurrent chemoradiotherapy (cCRT). The study aims to evaluate the efficacy and safety of volrustomig compared to observation in this patient population. Participants have tumors that express PD-L1 and the study is conducted as a Phase III, randomized, open-label, multi-center global trial. Participants are assigned to receive either volrustomig as sequential therapy following cCRT or to an observation group. The treatment period involves monitoring participants who have completed definitive cCRT but remain unresected and have no evidence of metastatic disease. The study focuses on participants with Stage III, IVA, or IVB LA-HNSCC according to AJCC criteria, who have not undergone tumor resection before cCRT and have not been treated with radiotherapy alone. During the study, participants are regularly evaluated for progression-free survival, with follow-up lasting up to approximately 8 years to assess long-term outcomes. Researchers will monitor safety and disease progression closely. The overall participation duration includes screening, treatment or observation, and extended follow-up to capture both efficacy and safety data over time.

Researchers are evaluating the effectiveness of pemigatinib in adults with advanced or metastatic pancreatic cancer that has spread to nearby tissues, lymph nodes, or distant body parts, and that have specific genetic changes in the FGFR gene. The study focuses on patients whose cancer has FGFR2 gene fusions or other FGFR alterations, aiming to see if pemigatinib can block these abnormal gene functions to stop tumor growth and possibly improve quality of life. This is a phase II trial conducted nationwide using a fully decentralized telemedicine approach to reach participants. Participants receive pemigatinib as an oral medication once daily for 14 days within each 21-day cycle. Treatment continues unless the disease progresses or unacceptable side effects occur. Alongside the drug treatment, patients undergo various imaging tests including CT scans, MRI, optical coherence tomography (OCT), and when needed, whole body bone scans and dilated eye exams (ophthalmoscopy). After finishing treatment, patients are followed up at 30 days and then every four months for one year to monitor their condition. Throughout the study, patients provide blood samples and undergo scans to evaluate treatment response and detect resistance mutations. Researchers track the overall response rate for up to 24 months and assess safety and tolerability. Patients must comply with scheduled visits, tests, and oral medication intake. The total study participation includes treatment cycles and a follow-up period lasting up to approximately 16 months after treatment completion.

Researchers are evaluating the effectiveness and safety of Datopotamab Deruxtecan (Dato-DXd) with or without durvalumab compared to the investigator's choice chemotherapy combined with pembrolizumab in patients who have PD-L1 positive locally recurrent inoperable or metastatic triple-negative breast cancer (TNBC). This Phase III, randomized, open-label, international study aims to see if adding durvalumab to Dato-DXd can help patients live longer without their cancer worsening or simply live longer compared to standard chemotherapy with pembrolizumab. The study also examines how the treatments and cancer impact patients' quality of life. Participants will be randomly assigned to one of three treatment groups: Dato-DXd plus durvalumab, Dato-DXd alone, or investigator's choice chemotherapy (paclitaxel, nab-paclitaxel, or gemcitabine plus carboplatin) combined with pembrolizumab. All treatments are given by intravenous infusion. The study design includes stratification based on geographic location, disease-free interval history, and prior PD-1/PD-L1 treatment for early-stage TNBC. During the study, participants will have regular assessments to monitor their disease status using RECIST 1.1 criteria and undergo imaging reviewed by blinded independent central review. Researchers will track progression-free survival, quality of life, safety, and other health measures over an anticipated period of up to 33 months. Participants must provide tumor samples for PD-L1 testing, and safety monitoring will continue throughout the study.

Researchers are evaluating the safety and effectiveness of HLX22 combined with trastuzumab and chemotherapy as the first treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 2, double-blind, randomized, and multiregional study compares this combination against trastuzumab and chemotherapy with or without pembrolizumab. The study aims to measure how well the treatments work in controlling the disease and improving survival for up to five years. Participants will be randomly assigned to one of two groups. One group receives HLX22 at 15 mg/kg every three weeks along with trastuzumab, chemotherapy (XELOX regimen), and possibly a placebo for pembrolizumab. The other group receives a placebo for HLX22 plus trastuzumab, chemotherapy (XELOX), and possibly pembrolizumab every three weeks. Treatment continues until the disease worsens, unacceptable side effects occur, withdrawal of consent, or other protocol-specified reasons. Throughout the study, participants will undergo regular assessments including tumor scans reviewed by an independent committee to evaluate progression-free survival and overall survival over up to five years. Other evaluations include safety monitoring and organ function tests. The study tracks how long patients live without disease progression and overall survival, aiming to better understand the benefits and risks of HLX22 combined with current standard treatments.

Researchers are investigating the best way to combine chemotherapy and radiation therapy based on how patients with localized non-germinomatous germ cell tumors (NGGCT) in the brain respond to initial chemotherapy. This phase II study aims to optimize radiation treatment for those who respond well to induction chemotherapy to reduce spinal cord relapses, and to use higher dose chemotherapy followed by conventional radiation for patients who do not respond as well. The study evaluates various chemotherapy drugs that work to stop tumor growth in different ways and uses radiation therapy with high-energy x-rays or protons to kill tumor cells and shrink tumors. Participants receive induction chemotherapy with drugs including carboplatin, etoposide, ifosfamide, and thiotepa over multiple cycles. Based on their response, patients are assigned to one of two treatment plans: those with a good response receive whole ventricular plus spinal canal irradiation (WVSCI) radiation therapy, while those with less favorable responses may receive high-dose chemotherapy with peripheral blood stem cell transplantation followed by radiation therapy. Some patients may also undergo second-look surgery depending on their tumor response. Treatments are carefully scheduled and monitored for up to six weeks for radiation and multiple cycles for chemotherapy. During the study, participants undergo regular assessments including MRI scans, cerebrospinal fluid and blood sample collections, and neurocognitive and quality of life evaluations. Researchers monitor tumor response, progression-free survival, overall survival, and treatment side effects for up to 10 years after treatment. Additional evaluations compare outcomes based on radiation type and assess growth and blood counts in younger patients. Patient safety and treatment effectiveness are closely followed throughout the study period.

Researchers are evaluating combination chemotherapy treatments for patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) and relapsed favorable histology Wilms tumors (FHWT). This phase II trial aims to assess how adding vincristine and irinotecan to standard chemotherapy regimens affects event-free survival and overall survival compared to historical data. The study also explores kidney toxicity, tumor genetics, and radiation therapy techniques to reduce side effects in children with lung and liver metastases. Two chemotherapy regimens are studied. Arm I (Regimen UH-3) involves cycles of vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan given intravenously on specific days every 21 days. Radiation therapy is given around week 7 of cycle 3 if needed. Arm II (Regimen ICE/Cyclo/Topo) includes cycles of ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan given intravenously every 21 days, with surgery and/or radiation during certain cycles. Both arms include multiple cycles in absence of disease progression or unacceptable side effects. Participants undergo various scans like CT, PET, MRI, chest x-rays, ultrasounds, and bone scans throughout the trial. Blood samples and biopsies may be collected periodically. After treatment, patients are followed up every 3 months for the first 2 years, every 6 months for years 3-4, and once at year 5. The main outcomes measured are event-free survival and overall survival up to 5 years, along with monitoring kidney health and treatment effects.

Researchers are evaluating how well elacestrant works compared to standard endocrine therapy in adults with node-positive, Estrogen Receptor-positive (ER+), Human Epidermal Growth Factor-2 negative (HER2-) early breast cancer who are at high risk of the cancer returning. This is a Phase 3 global, multicenter, randomized, open-label study focusing on participants who have had early invasive breast cancer removed and meet specific receptor and risk criteria. The study aims to understand which treatment better prevents invasive breast cancer over up to five years. Participants will receive either elacestrant or one of several standard endocrine therapies, including anastrozole, letrozole, exemestane, or tamoxifen, all given as oral tablets. Treatments will be administered according to the study plan, with careful monitoring throughout the trial. The study includes adults who have already received between 24 and 60 months of prior endocrine therapy, with or without certain inhibitors, and who have completed or stopped these treatments as required. During the study, participants will be monitored for invasive breast cancer-free survival for up to five years. Researchers will perform regular assessments to track treatment effects, side effects, and cancer recurrence. The study also includes safety monitoring and may involve additional tests or evaluations as needed to ensure participant well-being throughout the trial.

Researchers are evaluating the safety and effectiveness of a new combination treatment using Surovatamig (AZD0486), a fully human bispecific monoclonal IgG4 antibody, together with rituximab. This Phase III, global, randomized, open-label study focuses on participants with untreated follicular lymphoma (FL) to see if this combination offers added benefits compared to three standard chemoimmunotherapy regimens chosen by the investigator. The study has two parts: a safety run-in and the main Phase III comparison. The first part, the Safety Run-in, compares different dose levels of Surovatamig plus rituximab to find the recommended Phase III dose (RP3D). The second part, Phase III, involves three groups: two groups receiving different schedules of Surovatamig plus rituximab, and one group receiving one of three standard regimens (R-CVP with rituximab maintenance, R-CHOP with rituximab maintenance, or Bendamustine plus rituximab maintenance) as chosen by the investigator. Treatment schedules and doses are monitored closely through the study. Participants will be followed for up to 10 years to monitor the occurrence and severity of side effects, treatment discontinuations, dose changes, and overall safety. The main goal is to assess whether the new combination is superior to standard treatments. Regular evaluations include safety assessments and monitoring treatment effects over time, with attention to both short-term and long-term outcomes.
