Trial Summary

What is the purpose of this trial?

This is a Phase 1, open-label, dose escalation study to assess the safety, tolerability, and preliminary efficacy of SOT201 as monotherapy for participants aged 18 years or above with advanced unresectable or metastatic solid tumors During dose escalation, the recommended dose(s) of SOT201 given every 3 weeks (Q3W) will be determined

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.

What data supports the effectiveness of the treatment SOT201 for metastatic cancer?

The research suggests that stereotactic body radiation therapy (SBRT), a treatment similar to SOT201, can improve progression-free survival in patients with certain types of metastatic cancer, such as breast and prostate cancer, when combined with standard treatments. This indicates potential effectiveness for SOT201 in managing metastatic cancer. ^{1 2 3 4 5}

Is SOT201 safe for humans?

SOT201, also known as S-1, has been shown to be generally safe in humans, with good tolerability and low toxicity in patients with advanced breast cancer. Common side effects include mild blood-related issues and gastrointestinal symptoms, but severe reactions are rare. ^{6 7 8 9 10}

I have serious heart problems.

I have or had lung inflammation that needed steroids.

Findings from Research

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.

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.

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.

In three cases of recurrent breast cancer with liver metastasis that were resistant to other anti-cancer drugs, S-1 treatment led to significant improvement, demonstrating its efficacy.

All patients tolerated S-1 well, maintained the full dose throughout treatment, and experienced long-term benefits, including over two years of therapeutic efficacy and improved quality of life.

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 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.

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 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.
