TLR8 Agonist VTX-2337 and Cyclophosphamide in Treating Patients With Metastatic, Persistent, Recurrent, or Progressive Solid Tumors

Stopped early · Phase 1

Conditions studied: Colorectal Adenocarcinoma, Metastatic Pancreatic Adenocarcinoma, Recurrent Breast Carcinoma, Recurrent Colorectal Carcinoma, Recurrent Melanoma of the Skin, Recurrent Non-Small Cell Lung Carcinoma, Recurrent Pancreatic Carcinoma, Recurrent Renal Cell Carcinoma, Solid Neoplasm, Stage IV Breast Cancer, Stage IV Non-Small Cell Lung Cancer, Stage IV Renal Cell Cancer, Stage IV Skin Melanoma, Stage IVA Colorectal Cancer, Stage IVA Pancreatic Cancer, Stage IVB Colorectal Cancer, Stage IVB Pancreatic Cancer

In brief

This phase Ib trial studies the best way of TLR8 Agonist VTX-2337 and cyclophosphamide in treating patients with a solid tumor that has spread from the primary site (place where it started) to other places in the body (metastatic), progressed for a long time (persistent), come back (recurrent), or is growing, spreading, or getting worse (progressed). TLR8 Agonist VTX-2337 may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving TLR8 Agonist VTX-2337 together with cyclophosphamide may be a better treatment for solid tumors.

Who can join

You may qualify if…

• Histologically or cytologically confirmed metastatic solid tumor, including but not limited to pancreatic adenocarcinoma, breast cancer, melanoma, renal cell carcinoma (RCC), colorectal adenocarcinoma, non-small cell lung cancer, and others approved by the principal investigator
• Persistent, recurrent or progressive disease following at least one prior line of systemic therapy and there is no available therapy likely to improve survival
• Measurable disease with >= 1 target lesion
• White blood cells (WBC) >= 4200/mm\^3
• Absolute neutrophil count (ANC) >= 1400/mm\^3
• Platelets (PLT) >= 100,000/mm\^3
• Lymphocytes >= 700/mm\^3
• Hemoglobin >= 10 g/dL
• Total bilirubin =< 1.5 X upper limit of normal (ULN) unless history of Gilbert's syndrome documented prior to first-line treatment of cancer and other liver function tests are within normal limits
• Prothrombin time (PT)/international normalized ratio (INR) and partial thromboplastin time (PTT) =< 1.2 x ULN unless on anticoagulation medication with stable dosing for at least one month; in addition, patient must be able to stop taking medication for up to a week in order to have percutaneous biopsies of tumor tissue performed
• Aspartate transaminase (AST) and alanine aminotransferase (ALT) =< 1.5 x ULN (=< 5 x ULN for patients with liver involvement)
• Creatinine =< ULN or a calculated creatinine clearance of >= 45 ml/min if creatinine is greater than the ULN
• Alkaline phosphatase =< 3 x ULN (=< 5 x ULN if liver or bone involvement)
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1
• Willing and able to provide informed written consent
• Willing and able to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study); Note: During the Active Monitoring Phase of a study (i.e., active treatment and observation), participants must be willing and able to return to the consenting institution for follow-up
• Estimated life expectancy >= 84 days (3 months)
• Willing and able to provide samples for correlative research purposes
• If female of child-bearing potential, have a negative pregnancy test =< 14 days prior to registration
• If fertile male or female of child-bearing potential, agree to consistently use a highly effective method of birth control (including birth control pills, barrier device, or intrauterine device) from the time of consent through 4 months following the last dose of study drug

You may not qualify if…

• Is pregnant, breastfeeding, or planning a pregnancy
• Known standard therapy for the patient's disease that is potentially curative
• Treatment with any systemic anticancer treatment or an investigational agent within 4 weeks and any radiation within 2 weeks of registration
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit subject safety or compliance with study requirements
• Active autoimmune disease, defined as any autoimmune condition currently requiring therapy (e.g., systemic lupus erythematosus, multiple sclerosis, inflammatory bowel disease, rheumatoid arthritis)
• History of other invasive malignancy, with the exception of non-melanoma skin cancer and well-excised cervical carcinoma in situ, =< 3 years prior to enrollment unless assessed by the principal investigator as unlikely to compromise subject safety or to interfere with the study's objectives
• Treatment with oral or parenteral corticosteroids dosed greater than 40 mg hydrocortisone daily or its equivalent (e.g., prednisone 10 mg, prednisolone 8 mg, or decadron 3 mg) =< 2 weeks of treatment initiation; or a clinical requirement for ongoing systemic immunosuppressive therapy
• History of central nervous system (CNS) metastases unless previously treated and stable for > 8 weeks prior to study initiation
• Immunocompromised patients and patients known to be human immunodeficiency virus (HIV) positive
• Hypersensitivity to pegfilgrastim or Escherichia (E.) coli derived proteins
