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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tested a combination of an oral bacterial product (VE800) and the immunotherapy drug nivolumab in 56 people with advanced or metastatic cancers like melanoma, stomach, and colorectal cancer. The goal was to see if the bacteria could help the immune system fight tumors better. Researchers measured safety and how many patients saw their tumors shrink.

What this could mean

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

Active substance
VE800 (a mix of 11 live bacteria) plus nivolumab (Opdivo)
What this could lead to
If it works, this could point toward a new way to boost the immune system to fight advanced cancers.
What could go wrong
This is an early, small study (56 people) testing safety and response. The bacteria mix may not work for everyone, and side effects are possible.

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

Partial Inclusion Criteria: * Patients with advanced or metastatic cancer who had received no more than 3 lines of prior systemic therapy for advanced/metastatic disease. * Histologically diagnosed advanced (unresectable) or metastatic cancer with at least one measurable lesion as per RECIST 1.1 * Tumor lesions amenable for biopsy, if deemed safe by the investigator * Toxicity from prior cancer therapy should have resolved to Common Terminology Criteria for Adverse Events (CTCAE) Grade ≤ 1 (excluding alopecia and neuropathy, where up to Grade 2 residual was allowed) Partial Exclusion Criteria: * Prior treatment with immune checkpoint inhibitor (iCPI) (Note: this criterion did not apply to patients with melanoma) * Receipt of any conventional or investigational systemic anti-cancer therapy within 21 days prior to the first dose of vancomycin * Concurrent chemotherapy, immunotherapy, biologic, or hormonal anti-cancer therapy. Agents such as bisphosphonates or denosumab were acceptable as prophylaxis for bone metastasis. * Patients must not have received a transfusion (platelets or red blood cells) within 4 weeks of the first dose of study treatment * Patients with an active, known or suspected autoimmune disease. Patients with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment were permitted to enroll. * Patients with known active hepatitis (e.g., hepatitis B or C) NOTE: Patients with previously treated hepatitis B or C were permitted to enroll if there was evidence of documented resolution of infection. * Received a fecal transplant, spore or other preparation of fecal material, isolated bacterial products, genetically modified bacteria, or VE800
