A Phase I, Single-arm, Open-label Clinical Study to Evaluate the Safety, Pharmacokinetics, and Preliminary Efficacy of CHT101 Cell Infusion in Adult Subjects With Recurrent or Progressive Malignant Primary Brain Tumors（CROWN）

Starting soon · Phase 1

Conditions studied: Brain (Nervous System) Cancers

In brief

Recurrent or progressive primary malignant brain tumors are among the malignancies with a poor prognosis. They refer to primary brain tumors that either recur after standard treatment or show disease progression during the course of standard therapy. This group includes a variety of histological types, most commonly glioblastoma, anaplastic astrocytoma, anaplastic oligodendroglioma, and primary central nervous system lymphoma.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Tumor tissue specimens must be CD70-positive as determined by immunohistochemistry (IHC).
• Subjects must be pathologically confirmed to have high-grade glioma, defined as WHO (2021) Central Nervous System Tumor Classification grade 3 or 4 gliomas; or primary central nervous system lymphoma (PCNSL).
• Contrast-enhanced magnetic resonance imaging (MRI) must demonstrate the presence of an intracranial space-occupying lesion, with at least one measurable lesion.
• At the time of signing the informed consent form (ICF), the Karnofsky Performance Status (KPS) score must be ≥70.

You may not qualify if…

• Patients with brainstem recurrence, spinal dissemination, or extracranial metastasis.
• History of bone marrow or solid organ transplantation. History of other primary malignancies within 5 years prior to study treatment. Prior receipt of CD70-targeted antitumor therapies, including but not limited to CD70-targeted cell therapies (autologous or allogeneic) and TCR-T therapy.
• Prior treatment with CAR-T therapy or other cell/gene therapies. Presence of acute or moderate-to-severe chronic graft-versus-host disease (GVHD) within 4 weeks prior to signing the informed consent form (ICF), or receipt of systemic therapy for GVHD within 4 weeks prior to the first infusion.
• Clinically significant cardiovascular disease. Epilepsy that is difficult to control with medication, or chronic symptoms and signs of intracranial hypertension.
• Inadequate bone marrow reserve or organ function. Pregnant or breastfeeding female subjects.
