An interventional study of The Sarah Nanotechnology System - intended to deliver thermal energy to malignant cells for the purpose of thermal destruction of these cells in patients with advanced metastatic solid tumors. in Metastatic Solid Tumors and Stage 4 Cancer, sponsored by New Phase Ltd.. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-05-15.
Sponsored by New Phase Ltd. · Not applicable, Interventional, and Device feasibility
This is a sequential, dose-escalation, non-randomized, prospective, early feasibility trial. The goal of this clinical trial is to gather information on the safety and the recommended dose of the Sarah Nanotechnology System. Eligible participants have stage 4 metastatic solid tumor(s), that is(are) not responding to conventional treatment or have declined standard treatment options.
The main question it aims to answer is:
Study participation involves:
The AMF heats up the iron oxide core in the nanoparticles, due to their magnetic properties, which in turn causes the temperature to increase within the tumor(s). Because cancer cells are more sensitive to heat than normal cells, the heat will damage the cancer cells potentially without harming the surrounding healthy tissues.
This is a sequential, open-label, dose-escalation, non-randomized, prospective early feasibility clinical investigation designed to evaluate the safety of the Sarah Nanotechnology System, comprising intravenously administered Sarah Nanoparticles (SaNPs) in combination with a low-frequency Alternating Magnetic Field (AMF) generated by the Electromagnetic Induction System (EIS).
The purpose of the study is to assess the safety profile of the SaNP and AMF combination and to identify the recommended dose and irradiation parameters for a subsequent feasibility study. The study will also provide initial information regarding device performance and efficacy.
Scientific and Technical Background:
The Sarah Nanotechnology System utilizes controlled magnetic hyperthermia to thermally damage malignant cells while sparing surrounding healthy tissue. Following a single intravenous administration, SaNPs, nanoparticles with iron oxide core, circulate systemically and preferentially accumulate within tumor tissue through the Enhanced Permeability and Retention (EPR) effect, then participant's upper torso is exposed to an AMF (≈ 290 ± 10% kHz) by the EIS (Electromagnetic Induced System). The obtained effect is heating at tumor site.
Because AMF exposure can also induce eddy currents on the skin surface a patient cooling blanket system continuously helps regulating body surface temperature. Vital signs and skin temperature are monitored in real time throughout irradiation.
Dose-Escalation Design:
The study follows a standard 3 + 3 sequential escalation design, once the recommended dose is identified, an expansion cohort will repeat it.
SaNP dose: 100% SaNP dose, calculated according to NOAEL. AMF parameters: 290 ± 10% kHz; total irradiation time up to 15 minutes in the first treatment cohort, increasing to 16-20 minutes at the next treatment cohort depending on safety review.
Dose-limiting toxicity (DLT) criteria and escalation rules follow standard early-phase device study methodology.
Treatment Procedure:
On the treatment day, participants undergo laboratory tests and ECG assessment before SaNP infusion. Approximately four hours post-infusion, participants are positioned within the EIS coil for AMF irradiation while covered by a cooling blanket, and analgesic administration per physician discretion. Skin surface and oral temperatures, vital signs, and participant comfort are continuously monitored. After irradiation, repeat laboratory and ECG evaluations are performed prior to discharge.
Follow-up assessments occur at 7 ± 2 days and 30 ± 5 days post-treatment and then every 3-6 months up to 5 years for long-term safety surveillance.
Adverse events (AEs) and serious adverse events (SAEs) will be documented and evaluated for severity and relatedness to device or procedure. Real-time safety oversight is performed by the investigator and sponsor medical monitor; the DSMB periodically reviews cumulative safety data and recommends escalation, expansion, or study termination.

Patients should have sufficient organ and bone marrow function on screening day and on procedure day as defined below:
Leukocytes ≥3,000/mcL ≥1,500/mcL ≥100,000/mcL Total ≤ 2.5 x limit of normal () (SGOT)/ALT(SGPT) ≤5 x institutional ULN Creatinine (GFR) ≥50 ml/min/1.73 m2 for patients with creatinine levels above institutional normal.

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.
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.
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).

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
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.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
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 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.
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.
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.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
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.

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.
