Phase 1b Safety Study of CMB305 in Patients With Locally Advanced, Relapsed, or Metastatic Cancer Expressing NY-ESO-1

Stopped early · Phase 1

Conditions studied: Sarcoma, Melanoma, Non-small Cell Lung Cancer, Ovarian Cancer

In brief

This is a Phase 1b, open label, multi-center study of CMB305 (sequentially administered LV305 \[a dendritic cell-targeting viral vector expressing the NY-ESO-1 gene\] and G305 \[NY-ESO-1 recombinant protein plus GLA-SE\]) in patients with melanoma, sarcoma, ovarian cancer, or non-small cell lung cancer that express NY-ESO-1.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Locally advanced, relapsed, and/or metastatic cancer
• Tumor histology consistent with one of the following: In Part 1, Dose Escalation - melanoma, NSCLC, ovarian cancer (including fallopian tube carcinoma), or sarcoma (any subtype). In Part 2, Patient Expansion - NSCLC, ovarian cancer (including fallopian tube carcinoma), or the sarcoma subtypes, synovial sarcoma or myxoid/round cell liposarcoma
• Tumor specimen positive for NY-ESO-1 expression by IHC and/or RT-PCR. At least one tumor must be accessible and patients must consent for biopsies in Arms C and D.
• Inadequate response, relapse, and/or unacceptable toxicity with one or more prior systemic, surgical, or radiation cancer therapies, and for whom curative standard therapy is not an option (except patients with NSCLC who must have experienced either an inadequate response, relapse, and/or unacceptable toxicity with two or more prior systemic, surgical, or radiation cancer therapies)
• ≥ 18 years of age 7. Life expectancy of ≥ 6 months per the investigator 8. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 9. ECG without evidence of clinically significant arrhythmia or ischemia 10. If female of childbearing potential (FCBP), willing to undergo pregnancy testing and agrees to use at least one highly effective or two effective contraceptive methods during the dosing period and for three months after last CMB305 injection 11. If male and sexually active with a FCBP, must agree to use highly effective contraception such as latex condom during the dosing period and for three months after last CMB305 injection

You may not qualify if…

• Investigational therapy within 3 weeks prior to CMB305 dosing
• Prior administration of other NY-ESO-1-targeting immunotherapeutics
• Significant immunosuppression from:
• Concurrent, recent (≤ 4 weeks ago) or anticipated treatment with systemic corticosteroids at any dose, or
• Other immunosuppressive medications such as methotrexate, cyclosporine, azathioprine (antihistamines, non-steroidal anti-inflammatory drugs and aspirin permitted) or conditions such as common variable hypogamma-globulinemia or exposures such as large field radiotherapy
• Cancer therapies, including chemotherapy, radiation, biologics or kinase inhibitors, G-CSF or GM-CSF within 3 weeks prior to the first scheduled CMB305 dosing
• Psychiatric, other medical illness or other condition that in the opinion of the PI prevents compliance with study procedures or ability to provide valid informed consent
• Significant autoimmune disease with the exception of alopecia, vitiligo, hypothyroidism or other conditions that have never been clinically active or were transient and have completely resolved and require no ongoing therapy
• Myocardial infarction within 6 months of study initiation, active cardiac ischemia or New York Heart Association (NYHA) Grade III or IV heart failure
• Inadequate organ function including:
• Marrow: Peripheral blood leukocyte count (WBC) < 3000/mm3, absolute neutrophil count ≤ 1500/mm3, platelets < 75000/mm3, or hemoglobin < 10 gm/dL
• Hepatic: alanine aminotransferase (ALT), and aspartate aminotransferase (AST) > 2.5 x ULN, total serum bilirubin > 1.5 x ULN (patients with Gilbert's Disease may be included if their total bilirubin is ≤3.0 mg/dL)
• Renal: Creatinine > 1.5x ULN
• Other: INR (prothrombin time ratio) or partial thromboplastin time (PTT) >1.5 x ULN
• History of other cancer within 3 years (except non-melanoma cutaneous malignancies and cervical carcinoma in situ).
• Active tuberculosis or recent (< 2 week ago) clinically significant infection or evidence of active hepatitis B, hepatitis C or HIV infection
• For melanoma: Uveal melanoma or LDH >1.1 x ULN
• Brain metastases considered unstable as:
• Without confirmed stability over 60 days in patients previously treated with prior surgery or radiation; OR
• Associated with symptoms and/or findings; OR
• Requiring corticosteroids or anticonvulsants in the prior 60 days
• Pregnant, planning to become pregnant, or nursing
• Known allergy(ies) to any component of CMB305 or CPA
