What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new drug, RO7616789, to determine its safety and effectiveness for individuals with advanced small cell lung cancer (SCLC) or neuroendocrine carcinoma (NEC) that has recurred after treatment. The trial aims to understand the drug's mechanism in the body and its potential to combat tumors. It includes different parts to identify the optimal dosage and further assess the drug's effects. Individuals who have been treated for SCLC or NEC, still have measurable disease, and have a life expectancy of at least 12 weeks might be suitable candidates. As a Phase 1 trial, this research focuses on understanding the treatment's effects in people, offering participants the opportunity to be among the first to receive this new drug.

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

The trial requires stopping any anti-cancer therapy, including chemotherapy, hormonal therapy, or radiotherapy, at least 21 days before starting the study treatment. Also, you cannot take medications that are known to prolong the QT interval. Other medications are not specifically mentioned, so it's best to discuss with the trial team.

Will I have to stop taking my current medications?

The trial requires that you stop any anti-cancer therapy, including chemotherapy, hormonal therapy, or radiotherapy, at least 21 days before starting the study treatment. Additionally, you cannot be on medications that are known to prolong the QT interval.

Is there any evidence suggesting that RO7616789 is likely to be safe for humans?

Research shows that RO7616789 is in the early stages of testing to determine its safety for humans. Since detailed safety information isn't available yet, the trial is closely monitoring safety. Researchers are primarily assessing how well participants tolerate the treatment and checking for any side effects.

In this type of study, participants receive different doses to identify the safest amount. If side effects occur, researchers can adjust the dose. This careful approach helps ensure the treatment is as safe as possible for participants.

RO7616789 is being tested for small cell lung cancer and neuroendocrine carcinoma. Although specific safety results from the trials are not yet available, initial human testing suggests some confidence in its safety. Safety remains the main focus at this stage, and researchers are working to ensure the treatment is well-tolerated. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about RO7616789 for small cell lung cancer because it introduces a novel dosing approach with potential benefits over the standard chemotherapy and immunotherapy options currently available. Unlike traditional treatments, RO7616789 is being tested with flexible dosing schedules, allowing for weekly or every-three-week intravenous administration, which could better accommodate patient needs and manage side effects. This flexibility, combined with the possibility of adjusting the dose based on individual patient tolerance, may lead to a more personalized and potentially more effective treatment option for patients with this aggressive cancer type.

What evidence suggests that RO7616789 might be an effective treatment for small cell lung cancer?

Research shows that RO7616789 targets a protein called DLL3, present in many cancer cells but absent in healthy cells. This makes it a promising treatment for small cell lung cancer (SCLC) and neuroendocrine carcinoma (NEC). Early lab studies have demonstrated that targeting DLL3 can help the immune system attack cancer cells more effectively. In this trial, participants will receive RO7616789 in different dosing regimens to evaluate its safety and effectiveness. Although data collection from human trials is ongoing, early tests have shown promise. This strategy positions RO7616789 as a potential new option for patients with these hard-to-treat cancers. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• RO7616789

Trial Overview

The study tests RO7616789's safety and how it affects the body and tumors in patients with certain cancers. It has three parts: increasing doses to find a safe level (Dose Escalation) and then giving that dose to more people (Dose Expansion).

How Is the Trial Designed?

Group I: Part 3: Dose Expansion Experimental Treatment 2 Interventions

Based on emerging data from Part 1 and 2, one or more dosing regimens will be further investigated in Part 3.

Group II: Part 2: RO7616789 Q3W: Dose Escalation Experimental Treatment 2 Interventions

Participants will receive a fixed dose of RO7616789, at a dose determined in Part 1, intravenously once every 3 weeks (Q3W) on Day 1 of each 21-day cycle. In case of toxicity, step-up (single or double) dosing may be explored.

Group III: Part 1: RO7616789 QW: Dose Escalation Experimental Treatment 2 Interventions

Participants will receive a fixed dose of RO7616789 intravenously once weekly (QW) per dose level on Day 1, 8, and 15 of each 21-day cycle. In case of toxicity, step-up (single or double) dosing may be explored.

Published Research Related to This Trial

The combination of the anti-PD-1 antibody budigalimab and the antibody-drug conjugate Rova-T was found to be tolerated in 31 patients with previously treated small cell lung cancer (SCLC), with common side effects including pleural effusion, fatigue, and cough.

This combination therapy showed an overall response rate of 24.1%, with one complete response and six partial responses, indicating promising efficacy despite the discontinuation of Rova-T's development.

Small cell lung cancer (SCLC) is highly aggressive and often relapses after initial treatment, leading to poor survival rates, highlighting the need for new therapeutic strategies.

Recent research has identified several molecular targets for SCLC, and new agents are being developed and tested in clinical trials to improve treatment outcomes for patients.

A phase I trial presented in 2015 indicates that rovalpituzumab tesirine, an experimental antibody-drug conjugate, shows potential effectiveness against recurrent small cell lung cancer, a type of cancer with limited treatment options.

This trial highlights the promise of rovalpituzumab tesirine as a new therapeutic approach for patients suffering from this challenging form of lung cancer.

ADC Shows Effectiveness in SCLC. [2015]

SU5416 effectively inhibited the growth of small cell lung cancer (SCLC) tumors in vivo, reducing tumor growth by at least 70% over a 3-week treatment period, and was as effective as carboplatin in certain chemotherapy-resistant models.

The drug works by blocking both tumor cell proliferation and angiogenesis, notably reducing microvessel density by about 50% and decreasing VEGF expression, highlighting its potential as a dual-action treatment for SCLC and other cancers expressing Kit.

Rovalpituzumab tesirine (Rova-T) shows modest efficacy in treating extensively-stage small-cell lung cancer (SCLC) with a 12.4% objective response rate among 339 patients, indicating limited effectiveness in the third-line and beyond setting.

The treatment is associated with significant adverse events, with 63% of patients experiencing grade 3-5 toxicities, including fatigue and pleural effusion, highlighting the need for careful monitoring during therapy.
