What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests a personalized therapy called GT201, made from a patient's own tumor-infiltrating lymphocytes (TILs). The goal is to see if these immune cells, grown in the lab and infused back into the patient, can shrink or eliminate advanced solid tumors. The study includes adults aged 18-70 with advanced solid tumors who have exhausted standard treatments. Participants receive a lymphodepleting regimen, the GT201 infusion, and IL-2, with some also receiving a PD-1 inhibitor. The trial aims to assess safety, tolerability, and anti-tumor activity.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
GT201, a personalized cell therapy made from a patient's own tumor-infiltrating lymphocytes (TILs), given with IL-2 and possibly a PD-1 inhibitor.
What this could lead to
If successful, this could offer a new treatment option for people with advanced solid tumors who have run out of standard therapies, potentially leading to durable remissions.
What could go wrong
This is an early-phase trial, so safety and effectiveness are not yet established. The therapy involves intensive chemotherapy and IL-2, which can cause severe side effects. It may not work for all tumor types.

Inclusion Criteria: Key eligibility criteria for inclusion in the study: * 1 Age 18\~70 years old; * 2 Diagnosed with: Phase 1 part: Patients with advanced solid tumors who have failed all standard therapy, have no standard therapy, or are intolerant of standard therapy Phase 2a part: Patients with an advanced or metastatic solid tumor enrolled in one of three (3) indications selected for dose expansion based on Phase 1 safety and preliminary activity. Patients must have progressed on or after standard-of-care therapy, or for whom no suitable standard therapy is available; * 3 At least one lesion that is resectable for the preparation of autologous TIL cells; * 4 At least one measurable lesion that meets the definition of RECIST v1.1 after tumor sampling; * 5 Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1; * 6 Expected survival ≥ 12 weeks; * 7 Non-surgically sterilized women of reproductive age who agree to use at least one medically recognized method of contraception during the study treatment period and for 1 year after the end of the study treatment period; and must have a negative serum test at screening, prior NMA-LD and cell infusion. Exclusion Criteria: Subjects will be excluded from the study for one or more of the following conditions: * 1 Patients with spinal cord compression that has failed to resolve after surgery and/or radiotherapy (patients with clinical evidence that symptoms have resolved after surgery or radiation therapy for ≥ 1 week prior to surgical sampling are eligible for enrollment); * 2 Bleeding events within 3 months prior to screening * 3 Patients with arterio-venous thrombotic events that occurred within 3 months prior to screening * 4 Have interstitial pneumonia or active pneumonia that is clinically significant at screening, or other respiratory conditions that severely affect lung function; * 5 Patients who have a left ventricular ejection fraction (LVEF) \< 45% or who are New York Heart Association (NYHA) Class grade \> grade 2; * 6 Participants with ≥ 3 untreated central nervous system (CNS) metastases; * 7 Have any historical or active autoimmune disease requiring systemic steroids, or immunosuppressive therapy (\> 10 mg/day of prednisone or equivalent); * 8 Malignant tumors other than the target indication within 5 years; * 9 The presence of refractory or intractable epilepsy, large amounts of pleural effusion, ascites, pericardial effusion, etc. that cannot be controlled by drugs, or other contraindications to IL-2 use; * 10 Patients with infectious diseases, will be excluded from the study; with some exceptions for HBV and HCV. * 11 Previous allogeneic bone marrow transplantation or solid organ transplantation;
