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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
