DFF332 as a Single Agent and in Combination With Everolimus & Immuno-Oncology Agents in Advanced/Relapsed Renal Cancer & Other Malignancies

Carcinoma, Renal Cell Clinical Trial

Official title: A Phase I/Ib, Open-label, Multi-center Study of DFF332 as a Single Agent and in Combination With Everolimus or IO Agents in Patients With Advanced/Relapsed ccRCC and Other Malignancies With HIF2α Stabilizing Mutations

Status Active, not recruiting

Clinical Trial Summary

This is first in human study of DFF332, a small molecule that targets a protein called HIF2α. By acting on HIF2α, DFF332 may be able to stop the growth of certain types of cancer. DFF332 will be tested at different doses as single agent and in combination with Everolimus (RAD001, an mTOR inhibitor), and also in combination with Spartalizumab (PDR001, an anti-PD1) plus Taminadenant (NIR178, an adenosine A2A receptor antagonist), in patients with advanced clear cell renal cell carcinoma and other malignancies with HIF stabilizing mutations.

Clinical Trial Description

This is a first in human (FIH), Phase I/Ib, open-label, multi-center study of DFF332 as a single agent and in combination with Everolimus or Spartalizumab plus Taminadenant in patients with advanced clear cell renal cell carcinoma and other malignancies with HIF stabilizing mutations.

The study consists of two parts, dose escalation and dose expansion. The dose escalation part of the study will initially evaluate DFF332 single agent. Dose escalation groups receiving DFF332 in combination with Everolimus or DFF332 in combination with Spartalizumab plus Taminadenant will open after at least two dose levels of single agent DFF332 have been evaluated.

The dose expansion part of single agent will include two treatment arms: Arm1A will enroll ccRCC patients (age 18 yo or above) and Arm1B will enroll patients with malignancies harboring HIF stabilizing mutations (age 12 yo and above). These include the following:

• Malignancies with VHL mutations (e.g. Von Hippel-Lindau disease)

• Malignancies with FH mutations (e.g. Hereditary leiomyomatosis and renal cell carcinoma)

• Malignancies with mutations in SDHD, SDHAF2, SDHC, SDHB, SDHA (e.g. Hereditary paraganglioma and pheochromocytoma syndrome)

• Malignancies with EPAS1/HIF2A mutations

• Malignancies with ELOC/TCEB1 mutations

The expansion part of the combination therapies will enroll patients with ccRCC and include Arm2A (DFF332 with Everolimus) and Arm3A (DFF332 with Spartalizumab plus Taminadenant). ;
