A Clinical Study of Nanocrystalline Megestrol Acetate in Concurrent Chemoradiotherapy for Locally Advanced Cervical Cancer

Locally Advanced Cervical Cancer Cachexia

Cervical cancer, ranking as the fourth most prevalent malignancy in women globally, presents significant challenges in nutritional management. Approximately 31% of patients develop cancer-related malnutrition/cachexia, with 10-20% of deaths directly attributable to nutritional depletion. The disease process and its treatment - particularly concurrent chemoradiotherapy (CCRT) - create a destructive cycle through multiple mechanisms. Tumor-derived factors (including activins and myostatin) and inflammatory cytokines (such as TNF-α and IL-6) actively promote muscle and fat catabolism. CCRT toxicity, especially from platinum-based drugs, worsens this condition by inducing mitochondrial dysfunction and accelerating protein degradation, leading to clinically significant sarcopenia. This metabolic disruption has dire consequences, with studies showing severe weight loss during CCRT correlating with a 2.37-fold increase in mortality risk (HR 2.37, p=0.036). Nanocrystalline megestrol acetate (MA) emerges as a promising therapeutic intervention with dual mechanisms of action. Centrally, it modulates D2 receptors to upregulate neuropeptide Y (NPY), effectively stimulating appetite. Peripherally, it suppresses key inflammatory cytokines (IL-6 and TNF-α), thereby reducing systemic inflammation and muscle wasting. Its efficacy is well-established, with endorsement from major oncology guidelines (ASCO, NCCN, ESMO) for cancer cachexia management. A comprehensive meta-analysis of 35 clinical trials involving 4,234 patients demonstrated MA's superiority over placebo, showing significant improvements in appetite (RR 2.2), weight gain (RR 1.6), and quality of life (RR 1.8). The nanocrystalline formulation represents a substantial pharmacological advancement over conventional MA. While traditional preparations have limited solubility (2 µg/mL) and require high-fat meals for adequate absorption, the nanocrystalline version (with particles reduced to 26.6 nm) demonstrates 22% greater bioavailability. This translates to clinically meaningful differences: fasting-state peak concentrations increase from 187 ng/mL to 1,133 ng/mL, the time to observable effect shortens from 14 days to just 3 days, and 12-week weight gain improves from 3.5 kg to 5.4 kg (with 40% being lean mass). Dose optimization studies confirm 800 mg/day as the optimal conventional MA dose, with the nanocrystalline equivalent being 625 mg/day due to its enhanced bioavailability. The proposed clinical investigation will evaluate this intervention in FIGO IB3-IVA cervical cancer patients (n=5) undergoing CCRT. The study employs a two-arm design comparing nanocrystalline MA (625 mg/day) plus CCRT against CCRT alone. Primary endpoints focus on BMI changes at 8 weeks, with secondary assessments of nutritional status, inflammatory markers, and quality of life measures. This research aims to establish nanocrystalline MA as a means to break the cachexia cycle in cervical cancer treatment, potentially improving both treatment tolerance and survival outcomes.

Neoadjuvant Inhaled Azacytidine With Platinum-Based Chemotherapy and Durvalumab (MEDI4736) - a Combined Epigenetic-Immunotherapy (AZA-AEGEAN) Regimen for Operable Early-Stage Non-Small Cell Lung Cancer (NSCLC)

Non-small Cell Lung Cancer (NSCLC) Carcinoma, Non-Small Cell Lung Non-Small Cell Lung Carcinoma Non Small Cell Lung Cancer +1

Background: Lung cancer is the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Surgery to remove the tumors is the standard treatment for people diagnosed with early stages of NSCLC. Despite complete removal of these tumors, many recur (happen again). An FDA-approved drug combination to treat early-stage NSCLC prior to the surgery is durvalumab plus standard chemotherapy. The FDA approved infusion drug azacytidine \[AZA\] is used to treat several diseases because it can rapidly kill dividing cells (including cancer cells) but it is not approved for NSCLC. An inhaled (aerosolized) form of AZA is also not approved for NSCLC. However, researchers want to know if an inhaled version of AZA can help improve treatment of people with NSCLC because inhaled AZA goes directly into the lungs with limited absorption into the bloodstream. Objective: To find the safest and most effective dose of inhaled AZA in participants with early-stage non-small cell lung cancer (NSCLC) that can still be removed by surgery. Eligibility: Adults aged 18 and older with operable early-stage NSCLC. Participants will be required to also enroll in NIH protocol 06C0014 which allows for pre- and post-treatment biopsies and bloodwork to be obtained for additional research studies. Design: Participants will be screened. They will have a physical exam with blood tests. Their medical records will be reviewed. They will have imaging scans and tests of their heart and lung functions. Participants will be required to have a tissue sample (biopsy) taken of their tumor prior to receiving study drug and again during surgery after Cycle 3; airway tissue biopsies and collection of collect bronchial (lung) fluid may also be done. Participants will receive the study treatment for 3 cycles. Each cycle is 21 days. They will need to come to the NIH Clinical Center (CC) on days 1-4 of Cycles 1-3. AZA will be given as a drug mist that can be inhaled (like the type of mist in an asthma inhaler) using a nebulizer at the NIH Clinical Center (CC) for 3 days in a row (consecutive days) during the first week of each cycle. The participant will inhale the AZA drug mist for 20 to 30 minutes each time. Participants will also receive durvalumab and a specific 2-drug assigned chemotherapy by intravenous (IV) infusion on day 4 of each cycle. Participants will have a follow-up visit 2 weeks after their last dose of study drugs. Then they will have planned surgery to remove the tumors. Participants will have additional follow-up visits at the NIH CC about 1 and 3 months after the surgery, and then for every 3 months for up to 3 years.

A Study to Evaluate Next-Generation Sequencing (NGS) Testing and Monitoring of B-cell Recovery to Guide Management Following Chimeric Antigen Receptor T-cell (CART) Induced Remission in Children and Young Adults With B Lineage Acute Lymphoblastic Leu...

B-All Acute Lymphoblastic Leukemia

Background: Chimeric antigen receptor T-cell (CART) therapy is a form of immunotherapy which can be used to treat people with relapsed B-ALL. For those who achieve remission after CART alone, it may cure up to 50% of people who receive this therapy. However, for people who relapse after CART, it can be hard to achieve remission again. In patients where CART fails, stem cell transplant (HCT) can be used to prevent relapse and achieve cure. But HCT can cause serious side effects. Better testing is needed to distinguish people who can be cured with CART alone from people who may also need to have HCT. Objective: To see if the use of a series of blood and bone marrow tests at regular intervals can help monitor for B-ALL relapse after CART therapy. Eligibility: People aged 1 to 25 years with B-ALL who have had CART therapy within the past 42 days. They must never have had a blood stem cell transplant; they must also have no measurable blood cancer cells. Design: Participants will visit the clinic every 2 weeks starting 42 days after they receive CART therapy. Each visit will be about the same amount of time as a regular clinic visit. about 8 hours. Participants will have blood drawn for testing on each visit. Bone marrow biopsy/aspirate will be done during 4 of the visits at routine timepoints after CART. A needle will be inserted to draw a sample of tissue from inside the bone in the hip. A small amount of blood and tissue will be tested with ClonoSEQ and to evaluate for normal B-cells side by side with the standard tests. The combined testing may help determine whether participants are eligible for HCT and/or at risk of relapse after CART. Participants will be in the study for 2 years.

Microneurographic Assessment of Peripheral Nerves in Healthy Volunteers and Individuals With Sensory Dysfunction Caused by Inherited Mutations in the PIEZO2 Gene

PIEZO2-Deficiency Syndrome

Background: PIEZO2 Deficiency Syndrome (PDS) is a genetic disorder that affects a person s ability to feel touches and pain. Researchers want to know more about how PDS changes nerve function. Objective: To compare nerve function in people with PDS to that in people without PDS. Eligibility: People aged 18 years and older with PDS enrolled in protocol 16-AT-0077. Healthy volunteers are also needed. Design: Participants will have at least 1 clinic visit. They will undergo a test that measures activity in the nerves. For the test: Participants will place their arm or leg in a comfortable position. Ultrasound will be used to locate nerves. A smooth wand will be slid over the skin to capture images of the structures below. Two thin needles will be inserted through the skin. These needles are much smaller than the kind used to draw blood. The needles will record nerve activity as different sensations are applied to the skin. These include mild electrical pulses; heat and cold; bending of the knee or elbow; vibration; air puffs; pulling a hair; and tapping, stroking (brushing), stretching, pinching, and pushing on the skin at different levels of force. Each test takes 5 to 10 minutes. Participants will describe the sensations they feel. Participants may opt for an additional test that measures how nerves respond after heat pulses are used to create mild redness on the skin. Researchers would like at least 2 tests from each person. Participants may return for up to 3 additional visits, if desired, to complete all the testing.

Background: High-grade neuroendocrine carcinomas (HGNEC) are cancers that develop in different parts of the body, including the digestive tract, genitals, neck, and head. One drug (belinostat), combined with 2 other drugs (etoposide and cisplatin), is approved to treat HGNEC. But some people may have a gene variant that affects how quickly their body gets rid of the drug; these people may do better with different dosages of belinostat. Objective: To test higher or lower doses of belinostat based on gene variants in people with HGNEC. Eligibility: People aged 18 years and older with HGNEC. Design: Participants will be screened. They will have a physical exam with blood tests. Some blood will be used for genetic testing. They will have imaging scans and a test of their heart function. Samples of tumor tissue may be collected. All 3 study drugs (belinostat, etoposide, cisplatin) are given through a tube attached to a needle inserted into a vein. Treatment will be given in 21-day cycles. For cycles 1 through 6: Participants will come to the clinic for the first 4 days. They will be given all 3 drugs. Imaging scans and other tests will be repeated. Each visit will last 4 to 8 hours. After cycle 6: Participants may continue treatment with belinostat alone. They will come to the clinic for the first 3 days of each cycle. They may continue treatment for up to 5 years if the drug is helping them. Participants will have a follow-up visit 30 days after their last dose of belinostat. Then they will receive follow-up visits by phone or email every 3 to 6 months.

Amyloid PET Imaging in the Baltimore Longitudinal Study of Aging

Aging

Background: Some people experience cognitive decline as they age. That is, they lose memory, problem-solving, and other mental abilities. Amyloids are groups of proteins that develop in the brain and increase in number as people age. Researchers want to use imaging scans to track amyloids in people s brains over time. Their goal is to find out if any changes are related to cognitive decline or other medical issues. Objective: To learn how amyloids may affect brain structure and function as people age. Eligibility: People aged 55 years and older who are enrolled in the Baltimore Longitudinal Study of Aging. Design: Participants will have imaging scans and other tests every 1 to 4 years, depending on their age. Those 80 and older will be scanned yearly. These scans will be done during regular BLSA visits. The scans will be positron emission tomography and computed tomography (PET CT). Participants will be given fluid through a tube inserted into a vein in their arm. The fluid is a tracer that will cause the amyloids to light up in the images. Then they will lie on a bed with their head inside a PET CT scanner. They will lie still for about 30 minutes. Participants will have tests to assess their memory and other mental skills. They will answer questions about their mood and daily life. These tests will take about 40 minutes to complete; they may be done in person or by phone. Participants will give a contact number for someone who can answer questions about the participant s daily routine. These questions may be answered in person or by phone. Participants will be in this study for 5 years.

Deciphering the Genetic Architecture of Autoimmune Diseases

Autoimmune Diseases

Background: Autoimmune diseases can be caused by genes people inherit from their parents. The gene changes that cause these diseases have been well studied in people with European and Asian ancestors. But some diseases behave differently in people who are native to North and South America. Researchers want to know more about the gene changes and other factors that may cause autoimmune diseases among these people. This project will be based in Peru. Objective: To study how gene changes can lead to autoimmune diseases in people native to Peru. Eligibility: People aged 18 years and older with an autoimmune disease. These may include systemic lupus erythematosus; Sjogren disease; scleroderma; rheumatoid arthritis; seronegative spondylo-arthropathies; and systemic vasculitis. Family members and healthy volunteers are also needed. Design: Participants will have 2 clinic visits; these will be 2 weeks apart. The clinics will be in Lima, Iquitos, and other sites in Peru. Visit 1: Participants will have a physical exam. They will answer questions about their health risks and habits. They will provide blood and urine samples. Visit 2: Participants will provide a second blood sample and a stool sample. They will talk about the results of their first clinical exam with researchers. The cost of travel to and from the clinics will be provided. Participants will get $30 per visit and a snack.

Modeling Host-Pathogen Interaction Using Lymphoid Organoids

Staphylococcal Infections

Background: Staphylococcus aureus (S.aureus) are bacteria that can make people sick. Sometimes, an S. aureus infection can develop inside the spine; these infections can lead to paralysis and death. Researchers do not know how S. aureus interacts with a person s cells to cause infections in the spine. Objective: To learn how S. aureus interacts with cells in the body using tissues from tonsils discarded after standard surgery to remove them. Eligibility: People aged 2 years and older who are scheduled to have their tonsils removed. Design: Researchers will select participants for the study based on review of their existing medical records, including results of blood tests; any imaging scans, including x-rays; and reports about tissue specimens. Participants will answer questionnaires about their health and past infections. They can do this online or on paper. Participants will collect a nasal swab 1 week before their surgery. They will be given a tool that looks like a long cotton swab. They will twirl it around inside their nose. The swab will pick up cells and fluids that will be used for research. After their surgery, the participant s surgeon will save samples of tonsil tissue. The surgeon will send these tissue samples and the nasal swab to researchers at the NIH. These tissues and the swab will be used in studies to help researchers understand how S. aureus interacts with cells in the body. They hope these studies will help them find better ways to treat S. aureus infections.

Experience and Management of Cancer Screening-Related Anxiety in Fanconi Anemia

Fanconi Anemia

Background: Fanconi anemia (FA) is a rare, inherited cancer syndrome. FA causes a range of physical issues. Children with FA may have abnormal features; these may include a small head and eyes and issues with their internal organs. Young adults have a much higher risk of cancer. To screen for these cancers, people with FA may need to pursue many visits with different doctors. This constant need for cancer screening may cause anxiety for people with FA. Objective: To learn more about anxiety related to cancer screenings in people with FA. Eligibility: Adults aged 18 years and older with FA. They must also be enrolled in FACSS. FACSS is a study that screens people with FA for cancer every year. Design: All data gathered for this study will occur during routine FACSS visits. No other visits are needed. An observer will be in the room during participants FACSS visits. The observer and participant will have a polite introduction. After that, the observer will not interact with participants in any way. The observer will note details about the participants, such as: * Body language. * Worries about screening. * Comments that suggest anxiety or depression. * Clinical environment, such as d(SqrRoot)(Copyright)cor and temperature. * Accessibility issues. These can include lights and noises as well as ease of traveling around the clinic center. * Evidence of social support, such as engaging in the FA community. * Challenges they ve had in FACSS. * Their motivation to participate in FACSS. * Relationship dynamics among clinic staff, participants, and their care partners. Data will also be collected from FACSS visit notes dating back to December 2024 and from participants medical records.
