What is the purpose of this trial?

This trial tests a new drug, ABBV-303, to determine its safety and effectiveness in treating various solid tumors. Participants will receive either ABBV-303 alone or in combination with another investigational drug, budigalimab. The study aims to identify the optimal dose and understand how the drugs interact. Ideal candidates for this trial are individuals whose previous cancer treatments were ineffective for their specific tumor type, such as relapsed lung or kidney cancer. Participants should be ready for regular hospital visits and frequent health checks throughout the study. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

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

In earlier studies, ABBV-303 was generally safe in animal tests, with no major safety issues observed with repeated administration. Researchers are still studying this drug to determine its safety and effectiveness in humans. Past research showed that budigalimab alone was well-tolerated by patients with certain cancers. Since this trial is just beginning, safety information for both treatments in humans remains limited. However, early-stage trials like this one primarily focus on ensuring the treatments are safe for further testing, so researchers will closely monitor any serious side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about ABBV-303 and budigalimab because they offer a novel approach to treating solid tumors. ABBV-303 targets specific cancer cell pathways that are often not addressed by standard chemotherapy or immunotherapy, potentially improving outcomes for patients with resistant or refractory tumors. Budigalimab, when used in combination, enhances the body's immune response against cancer cells, offering a synergistic effect that could outperform current treatments. This combination is particularly promising for hard-to-treat cancers like non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), and head and neck squamous cell carcinoma (HNSCC), where traditional options are limited.

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

Research shows that ABBV-303 targets a protein called c-Met, which often aids cancer cell growth and spread. By blocking this protein, ABBV-303 may help stop cancer progression. Early results suggest it could be effective in treating hard-to-treat solid tumors. In this trial, some participants will receive ABBV-303 as a monotherapy, while others will receive it with budigalimab, a drug that helps the immune system fight cancer. Initial data indicates that this combination may work even better. Although still in early testing, this combination aims to attack tumors more aggressively. The goal is to offer a new option for people whose cancers haven't responded to other treatments. ^{1 4 6 7 8}

Participants with R/R NSCLC will receive ABBV-303 at the recommended phase 1 expansion dose (RP1ED) as a monotherapy as part of the 3 year study duration.

Group VI: ABBV-303 Dose Escalation: Part 1B Combination Experimental Treatment 2 Interventions

Participants with R/R solid tumors will receive ABBV-303 in combination with budigalimab at or below the MTD as part of the 3 year study duration.

Group VII: ABBV-303 Dose Escalation: Part 1A Monotherapy Experimental Treatment 1 Intervention

Participants with (R)/refractory (R) solid tumors will receive ABBV-303 in escalating doses as a monotherapy until the maximum tolerable dose (MTD) is determined as part of the 3 year study duration.

Published Research Related to This Trial

Budigalimab, a monoclonal antibody targeting PD-1, demonstrated a safety profile similar to other PD-1 inhibitors, with the most common severe side effect being anemia in 22% of HNSCC patients and 13% of NSCLC patients.

In terms of efficacy, budigalimab showed objective response rates of 13% in head and neck squamous cell carcinoma (HNSCC) and 19% in non-small cell lung cancer (NSCLC), with median progression-free survival of 3.6 months and 1.9 months, respectively, indicating it may be a viable treatment option for these cancers.

A 68-year-old patient with stage IV lung adenocarcinoma showed an unexpected positive response to paclitaxel after failing treatment with pembrolizumab, an anti-PD-1 immunotherapy.

The patient experienced a response duration of over fourteen months with paclitaxel, suggesting that combining or sequencing chemotherapy with immunotherapy may enhance treatment effectiveness in certain cases.

The KEYNOTE-826 trial demonstrated that adding the PD-1 inhibitor pembrolizumab to standard chemotherapy significantly improves progression-free survival and overall survival in patients with advanced cervical cancer.

These results suggest that pembrolizumab could become the new standard treatment for patients with metastatic, recurrent, or persistent cervical cancer.

In the JAVELIN Lung 100 trial involving 1214 patients with advanced NSCLC, avelumab showed longer median progression-free survival (PFS) compared to platinum-based chemotherapy (8.4 months vs. 5.6 months), indicating its potential efficacy as a first-line treatment.

Although avelumab demonstrated longer median overall survival (OS) compared to chemotherapy (20.1 months vs. 14.9 months), the differences were not statistically significant, suggesting that while avelumab may be beneficial, it did not meet the primary objective of the trial.

Cadonilimab, a bispecific PD-1/CTLA-4 antibody, demonstrated a manageable safety profile with 28% of patients experiencing grade 3-4 treatment-related adverse events, indicating it can be safely administered to patients with advanced solid tumors.

In a phase 2 trial, cadonilimab showed promising antitumor activity, with an objective response rate of 32.3% in cervical cancer patients, suggesting its potential effectiveness in treating advanced solid tumors.

Cadonilimab is a bi-specific antibody targeting PD-1 and CTLA-4, developed for treating various solid tumors, and was approved in China in June 2022 specifically for patients with relapsed or metastatic cervical cancer who have not responded to platinum-based chemotherapy.

The approval of cadonilimab marks a significant milestone in cancer treatment, providing a new therapeutic option for patients with advanced cervical cancer after standard chemotherapy has failed.

Budigalimab, a monoclonal antibody targeting the PD-1 receptor, demonstrated a manageable safety profile in a phase I trial with 59 patients, showing only 18.6% experiencing immune-related adverse events, and no grade 5 adverse events reported.

The drug achieved over 99% PD-1 receptor saturation within 2 hours of dosing, indicating effective pharmacodynamics, and showed comparable pharmacokinetics and safety profiles between Japanese and Western patients, supporting its potential as a viable treatment for advanced solid tumors.

The combination of MEDI0680 and durvalumab was found to be safe and tolerable in patients with advanced clear-cell renal cell carcinoma, but it did not show improved efficacy compared to nivolumab alone, with objective response rates of 16.7% for the combination and 23.8% for nivolumab.

Both treatment groups had a median progression-free survival of 3.6 months, and a notable percentage of patients (23.8% in the combination group) discontinued treatment due to adverse events, highlighting the need for careful monitoring of side effects.
