Breast Cancer Clinical Trial
Study of SO-C101 and SO-C101 in Combination With Pembro in Adult Patients With Advanced/Metastatic Solid Tumors
A multicenter open-label phase 1/1b study to evaluate the safety and preliminary efficacy of SO-C101 as monotherapy and in combination with pembrolizumab in patients with selected advanced/metastatic solid tumors
This study will assess the safety and tolerability of SO-C101 administered as monotherapy and in combination with an anti-PD-1 antibody (pembrolizumab) in patients with selected relapsed/refractory advanced/metastatic solid tumors (renal cell carcinoma, non-small cell lung cancer, small-cell lung cancer, bladder cancer, melanoma, Merkel-cell carcinoma, skin squamous-cell carcinoma, microsatellite instability high solid tumors, triple-negative breast cancer, mesothelioma, thyroid cancer, thymic cancer, cervical cancer, biliary track cancer, hepatocellular carcinoma, ovarian cancer, gastric cancer, head and neck squamous-cell carcinoma, and anal cancer).
Patients with selected histologically or cytologically confirmed advanced and/or metastatic solid tumors who are refractory to or intolerant of existing therapies known to provide clinical benefit for their condition.
ECOG performance score 0-1. Patients with ECOG is 2 to be discussed with the sponsor's medical monitor to be agreed for inclusion.
Estimated life expectancy of ≥3 months
Washout periods: 4 weeks for chemotherapy, 4 weeks or 5 half-lives (whichever shorter) for biologic agents including immuno-oncology therapy and 4 weeks from major surgeries, definitive radiotherapy and 2 weeks after palliative radiotherapy
At least one measurable lesion per iRECIST in a non-irradiated port. If in a previously irradiated port, must have demonstrated progression since best response to radiation therapy.
Have fully recovered from previous treatment to grade ≤1 toxicity (excluding alopecia) or have stable grade 2 neuropathy
Adequate organ system function
Negative serum pregnancy test, if woman of child-bearing potential (WOCBP; non-childbearing is defined as greater than one year postmenopausal or surgically sterilized).
