What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effects of two medications, adavosertib (also known as AZD1775, taken orally) and durvalumab (also known as MEDI4736, given through an IV), for people with solid tumors unresponsive to other treatments. The researchers aim to assess how these drugs work together, focusing on safety and any early signs of cancer-fighting effects. Individuals with a history of solid tumors that no longer respond to standard treatments may be suitable candidates. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new combination therapy.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, especially those that are sensitive to CYP3A4 enzymes, two weeks before starting the study and during the trial. Herbal preparations must be stopped 7 days before the first dose. If you are on specific cancer treatments, you may need a longer washout period after discussing with the Medical Monitor.

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

Research has shown that adavosertib, when combined with chemotherapy, is safe and generally well-tolerated in patients with advanced solid tumors. Previous studies have demonstrated its potential in fighting tumors, which is encouraging for those considering trial participation. In another study, adavosertib showed promising results in patients with pancreatic and ovarian cancers, which are challenging to treat.

Durvalumab, also known as MEDI4736, has received approval for some cancers. Studies have found it safe for many patients with solid tumors. Common side effects include tiredness, diarrhea, and nausea, while serious side effects are rare but can include pneumonia and heart problems.

Both treatments have been tested separately, and their risks are known and usually manageable. Joining a trial can help researchers understand how these treatments work together, but it's important to weigh the potential benefits and risks. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Adavosertib (AZD1775) and Durvalumab (MEDI4736) for cancer treatment because it targets cancer cells in a unique way. Adavosertib works by inhibiting the enzyme WEE1, which plays a role in cell division, potentially enhancing the effectiveness of Durvalumab, an immunotherapy agent that blocks PD-L1, helping the immune system identify and attack cancer cells. This dual approach could offer a new line of attack against cancer cells, potentially improving outcomes compared to standard chemotherapy or immunotherapy alone. Furthermore, the flexibility in dosing schedules allows for tailored treatments based on patient needs and emerging data, potentially optimizing effectiveness and minimizing side effects.

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

This trial will explore the combination of durvalumab and adavosertib for treating cancer. Studies have shown that durvalumab works well for certain types of cancer. For example, in patients with a specific kind of lung cancer, those who took durvalumab had about a 56% chance of their cancer not worsening after 12 months, compared to 35% for those who took a placebo. Meanwhile, adavosertib targets a protein called Wee1, which aids cancer cell growth. Research suggests that adavosertib can enhance the effectiveness of other cancer treatments. Both drugs show promise for treating difficult solid tumors when used together in this trial. However, more research is needed to confirm their combined effectiveness. ^{1 3 6 7 8}

Trial Overview

The trial is testing the combination of two drugs: AZD1775 (adavosertib), taken orally, and MEDI4736 (durvalumab), given intravenously. It aims to evaluate their safety, how well they're tolerated by patients' bodies, how they affect the body's handling of drugs (pharmacokinetics), immune response effects (immunogenicity), changes in disease indicators (pharmacodynamics), and initial effectiveness against advanced solid tumors.

How Is the Trial Designed?

Group I: Dose Schedule D Experimental Treatment 2 Interventions

Published Research Related to This Trial

In a study involving 6610 patients with active rheumatoid arthritis, adalimumab was found to be generally well tolerated, with serious infections occurring in only 3.1% of patients, indicating a favorable safety profile.

At 12 weeks, adalimumab demonstrated significant effectiveness, with 69% of patients achieving an ACR20 response, and it was effective both alone and in combination with various DMARDs, including antimalarials and methotrexate.

In a study involving 58 patients with advanced squamous non-small-cell lung cancer (sqNSCLC) who had previously progressed on anti-PD-(L)1 therapy, the combination of durvalumab and tremelimumab showed minimal efficacy, with only a 7% response rate in those with primary resistance and no responses in the acquired resistance cohort.

The treatment resulted in a median progression-free survival of about 2 months and an overall survival of approximately 7.6 to 7.7 months, indicating limited effectiveness in overcoming resistance to prior therapies.

Tofacitinib at doses of 3 mg or higher taken twice daily showed significant efficacy in treating active rheumatoid arthritis, with ACR20 response rates reaching up to 71.9% by week 12, compared to 22.0% for placebo.

The treatment was generally well-tolerated, with manageable side effects, the most common being urinary tract infections and diarrhea, indicating a favorable safety profile for patients.

Durvalumab, an immunotherapy drug for non-small cell lung cancer (NSCLC), has shown significant activity and acceptable tolerability, especially in patients with at least 25% PD-L1 tumor expression, and has been established as a standard treatment following chemoradiation based on the PACIFIC study results.

While durvalumab is effective in wild-type EGFR and ALK patients, its efficacy is lower in those with EGFR mutations or ALK-positive status, highlighting the need for ongoing research into combination therapies and the management of treatment-related toxicity.

The combination of durvalumab and tremelimumab in cancer treatment is associated with a higher incidence of severe adverse events (32.6%) compared to durvalumab alone (23.8%), indicating increased safety concerns with the combination therapy.

Patients receiving the combination therapy also experienced higher rates of specific side effects such as diarrhea (15.6% vs. 8.1%), rash (11.1% vs. 6.5%), and treatment discontinuation (18% vs. 3%), highlighting the need for careful monitoring and patient counseling regarding these risks.

Durvalumab, a PD-L1 blocking antibody, has shown clinical efficacy and a manageable safety profile in treating advanced non-small-cell lung cancer, especially in patients with ≥25% PD-L1 expression.

The drug is being evaluated in various treatment settings, including as a monotherapy and in combination with other therapies, showing promising results particularly after chemoradiation, although lower response rates were noted in patients with EGFR and ALK mutations.

The combination of durvalumab and tremelimumab showed improved disease control rates in patients with head and neck squamous cell carcinoma compared to tremelimumab alone, indicating its potential efficacy in this cancer type.

The combination therapy had a tolerable safety profile, with no significant increase in treatment-related adverse events compared to monotherapy, suggesting it is a safe option for patients.

Durvalumab, a PD-L1 inhibitor, has been shown to be safe for patients with various solid tumors, with common side effects including pruritus and fatigue, based on a meta-analysis of 17 studies involving 1,529 patients.

Higher levels of PD-L1 expression in tumors are linked to better treatment responses to durvalumab, indicating that PD-L1 could serve as a useful biomarker for predicting the drug's efficacy.

In a Phase 3 trial involving 797 patients with rheumatoid arthritis who did not respond adequately to methotrexate, tofacitinib (5 or 10 mg twice daily) led to significant improvements in patient-reported outcomes (PROs) after 3 months, which were maintained over 24 months.

Patients receiving tofacitinib reported clinically meaningful enhancements in various aspects of health, including pain and quality of life, compared to those on placebo, with similar improvements observed in patients who switched from placebo to tofacitinib later in the study.
