Study summary

This phase I trial studies the side effects and best dose of L-selenomethionine when given together with axitinib in treating patients with clear cell renal cell carcinoma that has spread from the primary site (place where it started) to other places in the body and usually cannot be cured or controlled with treatment (advanced metastatic). L-selenomethionine may stop the growth of tumor cells by blocking the growth of new blood vessels necessary for tumor growth. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving L-selenomethionine together with axitinib may be a better treatment for advanced metastatic clear cell renal cell carcinoma.

Read the detailed description

This is a Phase I trial for safety and preliminary efficacy of the combination of axitinib and SLM for adult patients with advanced metastatic CCRCC. This will be a two part study consisting of a dose escalation and expansion study.

Dose-Escalation Part 1 (6-12 patients): SLM will be given twice daily for 14 days followed by once daily dosing in combination with axitinib 5 mg twice daily with titration according to package insert in patients with advanced renal cell carcinoma. Treatment will continue until disease progression or unacceptable toxicity. The MTD was determined to be 4000 mcg SLM.

Expansion Part 2: In this phase (approximately 19 patients), will be treated at the maximum tolerated dose (MTD) of SLM determined in the Escalation Part 1. It will be given orally twice daily for 14 days, followed by once daily dosing in combination with axitinib 5 mg twice daily with titration according to package insert in patients with advanced renal cell carcinoma. Treatment will continue until disease progression or unacceptable toxicity.

A pilot group of 10 subjects will have SLM dose calculated based on patients' BSA to characterize the dose-concentration relationship and estimate the effective administered dose of selenium necessary to achieve the target blood concentration range informed by preclinical data.

Terms in these criteria, in plain language(17)

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Informed consent

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.

RECIST

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.

Creatinine clearance (CrCl)

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.

ALT and AST (liver enzymes)

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.

ULN (upper limit of normal)

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.

Bilirubin

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.

Absolute neutrophil count (ANC)

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.

Platelets

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.

Hemoglobin (Hb)

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).

ECOG performance status

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.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. Incidence of Adverse Events (AE) Per CTCAE 4.03

    The AEs will be summarized and classified by body system and by treatment group. The type, incidence, severity, and causality of each AE, the duration of the event, and any required treatment interventions will be tabulated.

    Time frame: After 2 cycles (28 days)

  2. Pilot Phase - Determine Dose-concentration Relationship and Estimate the Effective Dose of SLM (Informed by Preclinical Data) Using the Continual Reassessment Method (CRM).

    Dose escalation for this pilot study will be conducted using a CRM in which the probability of exceeding a blood selenium concentration of 45 µM on Day 14 is being modeled. Prior probabilities of exceeding a blood selenium concentration of 45 µM on Day 14 were estimated based on preclinical and preliminary data from the initial trial. A one parameter logistic model with intercept set at 3 and an initial value of 1 for the slope will be used to estimate the dose-concentration relationship through sequential recursive Bayesian assessment. The target probability of exceeding 45 µM is ≤20%.

    Time frame: 14 days

Secondary outcomes

  1. Overall Response Rate

    The overall response rate is the percentage of patients with a confirmed complete response (CR) or partial response (PR) as assessed by Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

    Time frame: From treatment initiation to treatment end, up to 3 years

  2. Progression-Free Survival

    Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions

    Time frame: From treatment initiation up to 2 years

  3. Overall Survival

    Overall survival is defined as the time from study treatment initiation to death due to any cause. Patients still alive were censored at the last date known to be alive.

    Time frame: From treatment initiation up to 3 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
