Overview of the LUNRESERTIB trial
This is a Phase 1 study of LUNRESERTIB in people with certain advanced solid tumors.[1] The trial is authorised and plans to include 470 participants.[1] The study is looking at LUNRESERTIB alone and in combination with other study drugs, including RP-3500 and Debio 0123.[1]
Who the trial is for
The main group includes patients with advanced solid tumors and specific gene changes, such as CCNE1 amplification or harmful mutations in FBXW7 or another proprietary gene.[1] One part of the study also includes patients with advanced solid tumors carrying either CCNE1 amplification or harmful mutations in FBXW7 or PPP2R1A.[1] Another part focuses on patients with CCNE1 amplification and advanced high-grade serous ovarian, fallopian tube, or primary peritoneal cancer.[1]
What the study is testing
The main goal is to assess the safety and tolerability of LUNRESERTIB.[1] The trial also tries to find the maximum tolerated dose, which is the highest dose that can be given without unacceptable side effects.[1] Researchers then aim to choose a recommended Phase 2 dose and a preferred dosing schedule for later studies.[1]
Several trial modules are included in the study.[1] Module 1 studies LUNRESERTIB alone in eligible advanced solid tumors.[1] Module 2 studies LUNRESERTIB with RP-3500 in molecularly selected advanced solid tumors.[1] Module 4 studies LUNRESERTIB with Debio 0123 in selected advanced solid tumors and also looks at early anti-tumor activity in a group with CCNE1 amplification and certain gynecologic cancers.[1]
Some parts of the study compare a tablet form with a capsule form.[1] Another part checks how food may affect how the tablet is handled by the body, which helps guide future dosing instructions.[1]
What researchers are measuring
The trial measures treatment-emergent adverse events, which are side effects that appear after treatment starts.[1] It also records laboratory tests, vital signs, electrocardiograms (ECGs), physical examinations, and use of other medicines taken during the study.[1]
For dose finding, the study measures dose-limiting toxicities in several modules.[1] It also measures blood levels of LUNRESERTIB and uses pharmacokinetic values such as Cmax, Tmax, AUC, and elimination half-life to understand how the drug behaves in the body.[1]
In the part that looks at anti-cancer activity, researchers measure best percent change in tumor size, overall response rate, duration of response, clinical benefit rate, tumor marker response, and progression-free survival.[1] These results help show whether the treatment may be doing more than just being safe.[1]
Study design and trial parts
This is an interventional study, which means the researchers give a treatment and then observe the results.[1] The study has several modules that answer different questions about LUNRESERTIB, including safety, dose, drug levels, food effects, and early anti-tumor activity.[1]
- Module 1: Tests LUNRESERTIB alone in advanced solid tumors to learn about safety, tolerability, and the best dose.[1]
- Module 2: Tests LUNRESERTIB with RP-3500 in molecularly selected advanced solid tumors to study safety and dose finding.[1]
- Module 3: Compares tablet and capsule forms and checks whether food changes how the tablet is absorbed and processed.[1]
- Module 4: Tests LUNRESERTIB with Debio 0123 in selected advanced solid tumors and looks for early signs of tumor response in a gynecologic cancer group.[1]
Important terms explained
Solid tumor means a cancer that forms a mass or lump, unlike some blood cancers.[1] Gene amplification means there are extra copies of a gene, which can help doctors select patients for the study.[1] Mutation means a change in a gene, and this trial uses certain gene changes to choose participants.[1]
Overall response rate shows how many patients have a measurable tumor response.[1] Progression-free survival tells how long the cancer stays from getting worse.[1] Pharmacokinetics means how the body absorbs and handles the drug over time.[1]
