简要总结
This phase 1-2 trial studies the side effects and best dose of ipilimumab in combination with toll-like receptor 9 (TLR9) agonist SD-101 and radiation therapy in treating patients with recurrent low-grade B-cell lymphoma.
详细描述
Monoclonal antibodies, such as ipilimumab, may block cancer growth in different ways by targeting certain cells. Biological therapies, such as TLR9 agonist SD-101, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving ipilimumab in combination with TLR9 agonist SD-101 and radiation therapy may be a better treatment for B-cell lymphoma.
Study objectives are dose-limiting toxicity (DLT) and the treatment assessments tumor response and time-to-progression. Cohort 1 dose level is 10 mg ipilimumab, subsequent cohort is 5 or 25 mg ipilimumab.
- If 2 out of 6 patients experience a DLT in the first cohort (10 mg ipilimumab), the dose will be de-escalated to 5 mg ("Cohort -1").
- If 2 out of 6 patients experience a DLT at the 5 mg dose level, then the study will be stopped.

结局指标
主要结局
Number of Dose-limiting Toxicity (DLT) Events of Ipilimumab Plus a Fixed Dose of SD-101 (1 mg/Week)
时间窗: Up to 10 weeks
To determine the safety and tolerability of SD-101 (1 mg/week) and local low dose radiation plus escalating doses of subcutaneously (SC)-administered ipilimumab, the incidence of dose-limiting toxicities (DLT) will be assessed according to the following DLT definitions. Related adverse events (AEs) are toxicities. "Treatment" includes radiation therapy. * Grade 4 treatment-related AE * Any drug-related AE ≥ Grade 3, including injection site reaction * ≥ Grade 3 treatment-related clinical autoimmune reaction involving major organs (defined as liver, pancreas, lung, heart, kidney, bowel, bone marrow, eye, or central nervous system) which does not resolve to baseline or Grade 1 within 6 weeks * Treatment-related AE ≥ Grade 3 that persists despite adequate/maximal medical therapy and/or prophylaxis, EXCEPT * Treatment-related skin rash ≤ Grade 3, that does not require systemic steroid therapy or other immunosuppressive therapy OR * Grade 3 flu-like AEs * Uveitis ≥ Grade 2
次要结局
- Tumor Response(Up to 2 years)
- Median Time to Progression (TTP)(Up to 2 years)
