Study Endpoints

Primary Endpoints

Incidence and nature of Dose Limiting Toxicity (DLTs)
Up to 8 weeks (newly diagnosed glioblastoma (GBM)) or 6 weeks (recurrent GBM) after the first administration of [177Lu]Lu-NeoB

A dose-limiting toxicity (DLT) is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness/injury, or concomitant medications that occurs within the DLT observation period of \[177Lu\]Lu-NeoB. The National Cancer Institute Common Terminology Criteria for Adverse events (NCI CTCAE) version 5.0 will be used for all grading. In Group 1 (newly diagnosed GBM), the DLT observation period is defined as a total of 8 weeks (56 days) from the first administration of \[177Lu\]Lu-NeoB, to cover the entire duration of concomitant RT and TMZ combination with the first two administrations of \[177Lu\]Lu-NeoB. In Group 2 (recurrent GBM), the DLT observation period is 6 weeks (42 days) starting from the first administration of \[177Lu\]Lu-NeoB (at Week 1 Day 1) and accounting for assessment of the safety profile during 2 full cycles of \[177Lu\]Lu-NeoB.

Secondary Endpoints

Incidence and severity of Adverse Events (AEs) and serious Adverse Events (SAEs), changes in laboratory parameters, vital signs and Electrocardiogram (ECGs)
From date of enrollment till 28 days after end of Treatment, assessed up to approximately 17 months
Absorbed radiation doses of [177Lu]Lu-NeoB in organs and tumor lesions
Cycles 1, 3 and 5: Day 1 (1-4 hours post-dose/post-infusion (p.i.)), Day 2 (24 hours p.i), Day 3 (48 hours p.i), Day 8 (168 hours p.i) (1 cycle = 3 weeks (recurrent GBM) or 4 weeks (newly diagnosed GBM))
Concentration of [177Lu]Lu-NeoB in blood over time
Cycle 1: Day1 (Pre-dose (before start of infusion), end of infusion, 0.5, 1, 2, 4 and 6 hours (hr) post-dose/post-infusion (p.i.)), Day2 (24 hr p.i), Day3 (48 hr p.i), Day8 (168 h p.i) (1 cycle= 3 weeks (recurrent GBM) or 4 weeks (newly diagnosed GBM))

Frequently asked questions about Lu-NeoB

What is Lu-NeoB used for in glioblastoma?

Lu-NeoB is an investigational small molecule being studied for the treatment of newly diagnosed and recurrent glioblastoma. It is a radioligand therapy that delivers radiation directly to tumor cells. The drug is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who makes Lu-NeoB?

Lu-NeoB is being developed by Novartis AG, a multinational pharmaceutical company traded on the New York Stock Exchange under the ticker symbol NVS. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational therapy for glioblastoma.

What phase is Lu-NeoB in?

Lu-NeoB is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not yet received regulatory approval. The ongoing Phase 1 trial is a dose-finding study designed to evaluate the safety, tolerability, and preliminary efficacy of the drug in patients with glioblastoma.

What clinical trials is Lu-NeoB in?

Lu-NeoB is being evaluated in a single active Phase 1 clinical trial with the identifier NCT05739942. This study is a dose-finding trial enrolling 42 patients with newly diagnosed and recurrent glioblastoma. The trial is active but not recruiting participants and is being conducted in the United States, France, Germany, Italy, Portugal, and Spain.

Is Lu-NeoB the same as [177Lu]Lu-NeoB?

Yes, Lu-NeoB is also known as [177Lu]Lu-NeoB. The name [177Lu]Lu-NeoB refers to the radiolabeled form of the drug, where the lutetium-177 isotope is attached to the NeoB molecule. Both names refer to the same investigational therapy being developed for glioblastoma.
