What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment approach for individuals with solid tumors, using a combination of two drugs: M1774 (Tuvusertib) and Niraparib (Zejula). The main goal is to assess the safety and tolerability of these drugs both together and separately, as well as to understand their processing in the body. Individuals with advanced or metastatic cancer unresponsive to standard treatments might be suitable candidates. Participants must have controlled cancer, particularly in the brain, and meet specific health criteria. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Do I need to stop my current medications to join the trial?

The trial protocol mentions 'prohibited concomitant medication,' but it does not specify which medications are prohibited. It's best to discuss your current medications with the trial team to see if any need to be stopped.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Tuvusertib (M1774) is generally safe when used alone, with most participants experiencing no serious side effects. This makes it a promising candidate for further studies.

For Niraparib, studies involving 830 patients found that common side effects included nausea and tiredness, affecting more than 10% of users. These side effects can usually be managed by adjusting the dose.

When combined, Tuvusertib and Niraparib still present manageable side effects, indicating that their combined use is not too severe and suitable for further research. Overall, both treatments have demonstrated safety for humans in controlled settings. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

M1774, also known as Tuvusertib, is unique because it targets specific mutations in tumors that other treatments might not address. Researchers are excited about Tuvusertib because it works by inhibiting certain proteins that are crucial for tumor growth, offering a new avenue for treating solid tumors. Unlike standard chemotherapy, which attacks all rapidly dividing cells, Tuvusertib's targeted approach could lead to fewer side effects and more effective treatment outcomes for patients with specific genetic profiles. Additionally, its combination with Niraparib, a PARP inhibitor, is promising as it could enhance the overall effectiveness in combating resistant cancer cells.

What evidence suggests that this trial's treatments could be effective for solid tumors?

Research has shown that Tuvusertib (M1774) effectively targets cancer cells in lab tests. It halts cancer cell growth even at very low doses and outperforms similar treatments. In this trial, some participants will receive Tuvusertib (M1774) alone, while others will receive it with Niraparib, a drug that prevents cancer cells from repairing themselves. The researchers are studying this combination to determine if it can enhance cancer treatment. Early results suggest that this combination is safe and could be promising for treating solid tumors. These findings offer hope that M1774, alone or with Niraparib, could effectively combat certain cancers. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Niraparib

Trial Overview

The trial tests M1774 alone and combined with Niraparib, a PARP inhibitor, in people with certain solid tumors. It's an early-phase study to determine safety, tolerability, how the body processes the drugs (with/without food), and any preliminary signs of effectiveness.

How Is the Trial Designed?

Group I: Part B1: Combination Therapy Dose Finding Experimental Treatment 2 Interventions

B1a: Participants with baseline body weight less than (\<) 77 kilogram (kg) or platelets \<150,000 cubic per millimeter (mm\^3) will receive Niraparib once daily combined with different doses of Tuvusertib (M1774). B1b: Participants with baseline body weight greater than or equal to (\>=) 77 kg and or platelets \>= 150,000 mm\^3 will receive Niraparib once daily combined with different doses of Tuvusertib (M1774) and schedule determined as recommended dose for expansion (RDE) in Part B1a.

Group II: Part A5: China Dose Confirmation Monotherapy Experimental Treatment 1 Intervention

Starting at global RDE from Part A1, in China. Participants will initially receive Tuvusertib (M1774) once daily under fasting conditions. Additional schedules may be evaluated if needed.

Group III: Part A4: Japan Dose Confirmation Monotherapy Experimental Treatment 1 Intervention

Starting at global RDE from Part A1, in Japan. Participants will initially receive Tuvusertib (M1774) once daily under fasting conditions. Additional schedules may be evaluated if needed.

Group IV: Part A3 - Monotherapy Expansion Experimental Treatment 1 Intervention

Part A3 is an expansion of Part A1 where Tuvusertib (M1774) will be administered as a single agent at the RDE established in Part A1. Participants with defined loss-of-function mutation in ARID1A, ATRX and/or DAXX, and ATM will be enrolled.

Group V: Part A2 - Preliminary Food Effect Assessment Experimental Treatment 1 Intervention

Participants in the food effect assessment will receive Tuvusertib (M1774) at the dose and schedule determined as recommended dose for expansion (RDE) in Part A1. A single dose of Tuvusertib (M1774) will be administered on Day -7 under a fed (low-fat meal) or fasted condition, followed by a 1-week washout period. After completion of the scheduled food effect assessments, participants will follow the same schedule as participants in Part A1.

Group VI: Part A1: Monotherapy Dose Escalation Experimental Treatment 1 Intervention

Participants will initially receive Tuvusertib (M1774) once daily under fasting conditions. Additional schedules may be evaluated if needed.

Published Research Related to This Trial

Niraparib at a dose of 200 mg/day was determined to be the recommended phase 2 dose when combined with abiraterone acetate plus prednisone (AAP) for patients with metastatic castration-resistant prostate cancer (mCRPC), as it showed a tolerable safety profile with no new safety signals.

The combination of niraparib with apalutamide resulted in a higher incidence of dose-limiting toxicities, leading to the decision not to further evaluate this combination, highlighting the importance of monitoring drug interactions in treatment regimens.

Niraparib, a recently approved treatment for recurrent platinum-sensitive ovarian cancer, has demonstrated a high oral bioavailability of 72.7% in humans, indicating effective absorption when taken orally.

The study involved six patients who received a therapeutic dose of 300 mg of niraparib, followed by a small intravenous dose to measure its levels in the bloodstream, confirming its potential as a convenient oral treatment option.

Niraparib has been approved by the FDA for patients with complete or partial response to first-line platinum-based chemotherapy, regardless of their BRCAm or HRD status, expanding treatment options for more patients.

Olaparib, in combination with bevacizumab, has also received FDA approval for patients with epithelial ovarian cancer, indicating that PARP inhibitors are now beneficial not only for BRCAm and HRD-deficient patients but also for those with HRD-proficient tumors.
