Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.

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 Results may not be published yet.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.

Summary

This study tests a special bacteria (Clostridium novyi-NT) injected directly into tumors, combined with the immunotherapy drug pembrolizumab, for people with advanced solid tumors that haven't responded to standard treatments. The bacteria are designed to break down tumor cells from the inside, while pembrolizumab helps the immune system attack the cancer. The main goal is to find the safest dose of the bacteria and see if the combination can control the disease. Up to 18 participants will be treated at MD Anderson Cancer Center.

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

Inclusion Criteria: 1. Diagnosis of an advanced solid tumor malignancy. There must be a target tumor which is measureable, palpable or clearly identifiable under ultrasound or radiographic guidance and amenable to percutaneous injection of C. novyi-NT spores. The targeted lesion must have a longest diameter \>/= 1 cm and \< 12 cm and be measurable as defined by RECIST 1.1 criteria. The target lesion must not be located in either the thoracic, abdominal or pelvic cavities or in the brain. There must be no clinical, no functional, and no radiographic evidence of bone involvement at the site of the target lesion. 2. History of prior treatment with at least one line of systemic anticancer therapy, when an approved systemic therapy is available, and no curative option is available for continued treatment. 3. At least 4 weeks have elapsed since the completion of major surgery, and the patient has fully recovered from this surgery and any post-surgical complications. 4. Patient must have adequate organ function as indicated by the following laboratory values. Hematological: Absolute neutrophil count (ANC) \>/=1,500/mcL; Platelets \>/=100,000/mcL; Hemoglobin \>/=9g/dL or \>/= 5.6 mmol/L. Renal: Serum creatinine \</= 1.5 X upper limit of normal (ULN. Hepatic: serum total bilirubin \</= 1.5 X ULN OR Direct bilirubin \</= ULN for patients with total bilirubin levels \> 1.5 ULN; AST (SGOT) and ALT (SPGT) \</= 2.5 X ULN OR \</= 5 X ULN for patients with liver metastases. Coagulation: International Normalized ration (INR) or Prothrombin Time (PT) \</= 1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT of PTT is within therapeutic range of intended use of anticoagulants; Activated partial Thromboplastin Time (aPTT) \</= 1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT of PTT is within therapeutic range of intended use of anticoagulants. 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 6. Patient is at least 18 years of age. 7. Patient is capable of giving informed consent. 8. Female patient of childbearing potential has a negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. The serum pregnancy test must be negative for the patient to be eligible. 9. Patient of childbearing potential is using either 2 adequate barrier methods or a barrier method plus a hormonal method of contraception to prevent pregnancy or to abstain from heterosexual activity throughout the study, starting with Visit 1 through 120 days after the last dose of study therapy. Approved contraceptive methods include 2 of the following barrier methods or one barrier method combined with a hormonal contraceptive: a. Intra uterine device, diaphragm with spermicide, cervical cap with spermicide, male condoms, or female condom with spermicide. Spermicides or condoms alone are not an acceptable method of contraception. b. Male patients must agree to use an adequate method of contraception starting with the first dose of study drug through 120 days after the last dose of study therapy. 10. Patient has no significant valvular heart disease (trace or mild valvular stenosis or regurgitation is allowed). 11. Patient is able to stay within 45 minutes driving time of an emergency room for 28 days after dosing with C. novyi-NT. 12. The patient has a caregiver for 28 days after dosing with C. novyi-NT. 13. Patient has a tumor sample from C. novyi-NT planned injected tumor lesion (newly obtained biopsy) for PD-L1 and immunologic response assessments. Patients must submit the tumor sample during screening at a central pathology laboratory. Exclusion Criteria: 1. Patient who has had chemotherapy, radiation therapy, or biological cancer therapy within four weeks prior to the first dose of study drug, or who has not recovered to CTCAE Grade 1 or better from the AEs due to cancer therapeutics administered more than four weeks earlier. 2. Patient is currently participating or has participated in a study of an investigational agent or using an investigational device within 30 days of the first dose of study drug. (A patient in the survival Follow up phase of an investigational agent where no further treatment is expected is eligible). 3. Patient is on any systemic corticosteroid therapy within one week before the planned date for first dose of treatment or on any other form of immunosuppressive medication. 4. Documented primary brain malignancy or brain metastases. 5. Patient previously had a severe hypersensitivity reaction to treatment with another mAb. 6. Patient has an active autoimmune disease or a documented history of autoimmune disease or syndrome that requires systemic steroids or immunosuppressive agents. Patients with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Patients that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Patients with hypothyroidism stable on hormone replacement will not be excluded from the study. 7. Patient has an active infection requiring systemic therapy. 8. Patient has known history of Human Immunodeficiency Virus (HIV) (HIV ½ antibodies). 9. Patient has a known history of or is positive for Hepatitis B (HBsAg reactive) or Hepatitis C (HCV RNA \[qualitative\] is detected). 10. Patient is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study. 11. Patient has received a live vaccine within 30 days prior to first dose. 12. Patient has a foreign body which in the opinion of the treating investigator could be difficult to manage in case of infection. 13. Clinically significant pleural effusion. 14. Clinically significant pericardial effusion, circumferential pericardial effusion, or any effusion greater than 1.0 cm at any location around the heart. 15. Need for ongoing treatment with an immunosuppressive agent. 16. History of solid organ transplantation (with the exception of a corneal transplant \> 3 months prior to screening). 17. History of an ischemic insult in the previous 12 months (myocardial infarction, cerebral vascular accident, ischemic tissue from injury, transient ischemic attack). 18. History of a significant medical illness deemed by the PI as unsuitable for the trial. For example: i. Symptomatic congestive heart failure ii. Psychiatric Illness/social situation that may make study dangerous iii. Unstable angina pectoris. 19. History of asplenia. 20. Antibiotic allergies that would preclude treatment for a C. novyi-NT infection. 21. Treatment with antibiotics within 2 weeks (14 days) of dosing. 22. Oxygen saturation (Sp02) of less than 95% on room air. 23. Mean arterial blood pressure (BP) of less than 70 mmHg. 24. Glasgow Coma Score of less than 15. 25. History of (non-infectious) pneumonitis that required steroids or current pneumonitis.
