A Trial of AVID200, a Transforming Growth Factor β (TGFβ) Inhibitor, in Patients Malignancies

Completed · Phase 1

Conditions studied: Malignant Solid Tumor

In brief

TGFβ has profound local immunosuppressive and immunoexclusion effects in the tumor microenvironment that are integrally involved in the failure of immune checkpoint inhibitors in some tumors. Preclinical data in a variety of models strongly support the study of AVID200 in patients with treatment-refractory advanced and metastatic malignancies as an approach to reducing immunosuppression/exclusion and increasing the activity of immune checkpoint inhibitors.

You may qualify if…

Patients with a documented (histologically or cytologically proven) solid tumor malignancy that is locally advanced or metastatic
Patients with a malignancy that is currently not amenable to surgical intervention due to either medical contraindications or non-resectability of the tumor
Patients with a malignancy that is either refractory to, or the patient is intolerant of existing therapy(ies) known to provide clinical benefit, or for which no standard therapy is available
Patients with measurable or non-measurable disease according to RECIST, v1.1
Patients with an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 (or equivalent Karnofsky PS), and anticipated life expectancy of ≥ 3 months
Patients and their partners who are either not of childbearing potential or who agree to use a highly effective, non-hormonal, method of contraception during the study and continuing until 4 months after the last dose of study drug); male patients agreeing to refrain from sperm donation during this period.
Patients with the ability to understand and give written informed consent for participation

You may not qualify if…

Patients with an active second malignancy or history of another malignancy within the last 2 years with the exception of:
Treated non-melanoma skin cancers
Treated carcinoma in situ (CIS) of the breast, cervix, bladder, colon, endometrium, skin (melanoma) provided complete response (CR) was achieved at least 2 years prior to study and no additional therapy is ongoing or required during study period with the exception of anti-estrogen/androgen therapy or bisphosphonates
Controlled, superficial carcinoma of the bladder
T1a carcinoma of the prostate comprising < 5% of resected tissue and prostate specific antigen (PSA) within normal limits (WNL) since resection
Any antineoplastic agent for the primary malignancy (standard or investigational), without delayed toxicity, within 4 weeks or 5 plasma half-lives, whichever is shortest, prior to C1/D1 and during study with the exception of:
Nitrosoureas and mitomycin C within 6 weeks prior to C1/D1 and during study
Any other investigational treatments within 4 weeks prior to and during study; includes participation in any medical device or supportive care therapeutic intervention trials
Radiotherapy for target lesions within 4 weeks prior to C1/D1 and during study; radiotherapy for non-target lesions within 2 weeks prior to C1/D1
Radiotherapy within 2 weeks prior to C1/D1 and during study. Patients must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.
Use of live vaccines against infectious diseases 4 weeks prior to C1/D1 and during study
Immunosuppressive or systemic hormonal therapy (> 10 mg daily prednisone or equivalent) within 2 weeks prior to C1/D1 and during study
Prophylactic use of hematopoietic growth factors within 2 weeks prior to C1/D1 and during Cycle 1 of study; thereafter prophylactic use of growth factors is allowed as clinically indicated
