What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test the safety and initial effectiveness of a new treatment called SOT201 for individuals with advanced solid tumors that cannot be surgically removed or have metastasized. Participants will receive SOT201 through an IV every three weeks to determine the safest effective dose. This trial may suit those who have tried other treatments without success and can undergo a new tumor biopsy if needed. As a Phase 1 trial, participants will be among the first to receive this treatment, aiding researchers in understanding its effects in humans.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, there are restrictions on certain prior therapies and medications, so it's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that SOT201 is likely to be safe for humans?

Research has shown that SOT201 is generally safe for people. In earlier studies, patients with advanced breast cancer tolerated it well, experiencing only mild side effects. This research aims to determine the most effective dose while minimizing side effects. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

SOT201 is unique because it is administered intravenously once every 21 days, offering a potentially more convenient dosing schedule compared to some current metastatic cancer treatments that often require more frequent administration. Researchers are excited about SOT201 because it may provide a different mechanism of action, targeting cancer cells in a novel way that could enhance effectiveness or reduce side effects. This new treatment option could complement or offer an alternative to existing therapies, expanding the arsenal against metastatic cancer.

What evidence suggests that SOT201 might be an effective treatment for metastatic cancer?

Research has shown that SOT201, the investigational treatment in this trial, has strong potential in fighting cancer based on early tests. In studies with mice, SOT201 completely shrank or eliminated tumors. This treatment blocks PD-1, a protein that some cancers use to hide from the immune system. By blocking PD-1, SOT201 may help the body's defenses attack cancer cells more effectively. These promising results in animal studies suggest that SOT201 could be effective for treating advanced cancers in humans. ^{3 5 6 7 8}

Are You a Good Fit for This Trial?

Adults with advanced or metastatic solid tumors that have worsened after standard treatments can join this trial. They must be able to provide a fresh tumor biopsy, have an ECOG score of 0-1 indicating they are fully active or restricted in physically strenuous activity but ambulatory, and their organs must function well. People who've had severe reactions to certain immune therapies or recent radiation, those with specific heart issues, autoimmune diseases needing treatment within the last two years, active infections requiring therapy (except HIV/Hepatitis B), or life expectancy under three months cannot participate.

Inclusion Criteria

I can provide a fresh biopsy of my tumor or am willing to undergo one if needed.

My organs are functioning well enough for treatment.

I am fully active or can carry out light work.

Exclusion Criteria

Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the patient's participation for the full duration of the trial, or is not in the best interest of the patient to participate, in the opinion of the treating investigator

I have serious heart problems.

I have or had lung inflammation that needed steroids.

In a phase III trial involving 926 patients with advanced non-small-cell lung cancer, the addition of sorafenib to carboplatin and paclitaxel chemotherapy did not improve overall survival compared to chemotherapy alone, with median survival times of 10.7 months and 10.6 months respectively.

Patients with squamous cell lung cancer who received sorafenib actually experienced higher mortality rates compared to those who received placebo, highlighting potential safety concerns with this treatment combination.

In a late phase II clinical study involving 81 patients with advanced or refractory breast cancer, S-1 demonstrated a response rate of 42.0%, with a median survival period of 910 days, indicating its potential effectiveness as a treatment.

S-1 was associated with manageable adverse reactions, with severe side effects occurring in a small percentage of patients, suggesting it has a favorable safety profile compared to other treatments.

Metastatic breast cancer remains largely incurable, with a median survival of only 2 to 3 years after diagnosis, highlighting the need for effective palliative care.

Recent advancements in endocrine and chemotherapeutic agents have improved treatment options for receptor-positive patients, making single-agent therapy a viable palliative approach, and emphasizing the importance of clinical trials for accessing cutting-edge therapies.

In a randomized phase II trial involving 62 patients with oligorecurrent prostate cancer, metastasis-directed therapy (MDT) significantly improved androgen deprivation therapy (ADT)-free survival, with a median of 21 months compared to 13 months for the surveillance group.

The study found that MDT was associated with low toxicity, as only six patients experienced grade 1 side effects, and no severe toxicities were reported, indicating that MDT is a safe option for patients.

Stereotactic body radiotherapy (SBRT) effectively delays the need for subsequent systemic treatment in patients with oligoprogressive breast cancer, with a median time to next systemic treatment of 8 months based on a study of 79 patients.

The study found that a higher biological effective dose (BED) of SBRT (>70Gy10) significantly improved freedom from local progression (86.7% overall), indicating that treatment intensity can influence outcomes.

A mathematical model developed from human bone metastatic prostate cancer biopsies can predict individual patient responses to treatments like abiraterone acetate/prednisone, helping to estimate initial resistance to androgen deprivation therapy (ADT).

This model allows for the optimization of treatment sequences based on patient-specific data, potentially delaying the progression of resistant disease and improving patient outcomes in bone metastatic prostate cancer.

This multicenter randomized phase III trial aims to determine if combining Stereotactic Body Radiation Therapy (SBRT) with standard systemic treatment improves progression-free survival in patients with solid tumors and up to 3 bone-only metastases, with a total of 196 patients expected to be enrolled over 4 years.

The primary goal is to assess progression-free survival at 1 year, while secondary outcomes will evaluate local control, cancer-specific survival, quality of life, and pain management, highlighting the potential for SBRT to enhance patient outcomes by controlling bone metastases.

In a multicenter phase II study involving 145 patients with recurrent or metastatic sarcoma, sorafenib showed a partial response rate of 14% specifically in patients with angiosarcoma, indicating some efficacy for this subtype.

Despite its limited effectiveness in other sarcoma types, sorafenib was associated with significant adverse events, leading to dose reductions in 61% of patients, highlighting the need for careful monitoring and potential combination therapies to enhance its therapeutic impact.

In a phase II trial involving 56 patients with metastatic breast cancer, sorafenib showed limited efficacy, with only 2% achieving a partial response and 37% experiencing stable disease, but 22% had disease stabilization for at least 16 weeks.

The treatment was associated with a manageable safety profile, with common grade 3 adverse events including rash (6%) and fatigue (4%), suggesting that while sorafenib alone may not be effective, it could be explored in combination with other therapies.
