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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 phase 1 trial tests an experimental therapy called AB-1015 in people with ovarian, fallopian tube, or primary peritoneal cancer that has stopped responding to platinum-based chemotherapy. AB-1015 uses a patient's own T cells, which are genetically engineered to recognize and attack tumor cells. The study aims to find the safest dose and to see whether the treatment can shrink tumors or slow the disease.

What this could mean

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

Active substance
AB-1015, a type of engineered T-cell therapy (also called Integrated Circuit T cells) made from the patient's own immune cells
What this could lead to
If AB-1015 proves safe and effective, it could offer a new treatment option for ovarian cancer that has stopped responding to standard chemotherapy, potentially leading to durable remission.
What could go wrong
This is an early-phase trial with a small number of participants, so the therapy may not work or could cause severe side effects like cytokine release syndrome or neurological toxicity. The results will need confirmation in larger studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Recurrent, advanced, platinum resistant ovarian, fallopian tube, and primary peritoneal cancer and must have a histological diagnosis of a high-grade serous histology. * a) Platinum resistant disease is defined as progression of disease within six months of platinum regimen. * Doubling of cancer antigen 125 (CA-125) level on 2 successive measurements may be considered as meeting the definition of disease progression * b) Have received at least 2 lines of prior therapy including a platinum-based regimen if eligible and a poly-ADP ribose polymerase (PARP) inhibitor if BRCA1/2 mutated. No more than 3 lines of prior therapy for the treatment of platinum resistant disease is permitted. * Adequate organ function as per protocol definitions. * Eastern Cooperative Oncology Group (ECOG) performance status score 0 or 1. * Evaluable disease (dose escalation cohorts) or measurable disease (backfill cohorts) at time of enrollment as per protocol definitions. * Negative pregnancy test for women of childbearing potential. Women of non-childbearing potential are those who have been surgically sterilized, have medically confirmed ovarian failure, or have not had menses within the past 12 months. Exclusion Criteria: * Cytotoxic chemotherapy within 14 days of time of cell collection. * Cytotoxic chemotherapy within 14 days of starting of conditioning chemotherapy. * New York Heart Association functional class II-IV cardiovascular disability * Clinically significant pericardial effusion * Pleural or peritoneal effusion that requires drainage for symptom management within 28 days of screening. * Active autoimmune disease requiring immunosuppressive therapy or uncontrolled with treatment. * Untreated brain metastasis. * Subjects unwilling to participate in an extended safety monitoring period.
