Brief Summary:
The purpose of this study is to find out whether the study drug, TSR-042, followed by standard chemoradiotherapy (the chemotherapy drug capecitabine + radiation therapy) and standard surgery is an effective treatment for advanced dMMR solid tumors. The study will also look at the safety of the study drug.

Drug Information available for: Dostarlimab

Arm Intervention/treatment
Experimental: Cohort 1
Patients with clinical Stage II or Stage III MRI-staged, MSI-H or dMMR, solid tumors will receive up to 6 months (9, 21-day cycles) of PD-1 blockade followed by radiological and surgical restaging of the tumor. If subject exhibits complete clinical response, non-operative management will be followed. If a complete clinical response is not reached after 6 months of PD-1 blockade, the participant will proceed with standard chemoradiation. After completing chemoradiation participant will be assessed for response if complete CR is not obtained then the participant will proceed with disease specific surgical resection or standard of care therapy.
Drug: TSR-042 or Dostarlimab
Patients will be given TSR-042/Dostarlimab at a dose of 500mg IV, over 30 minutes Q 3 weeks.
Other Name: Dostarlimab

Drug: capecitabine or 5-FU
Capecitabine 825mg/m2 BID concurrently with radiation per standard radiation guidelines. If patient is unable to tolerate oral medication, infusional 5-FU is an acceptable alternative.

Radiation: Intensity Modulated Radiation Therapy (IMRT)
The radiation dose is 5400 cGy to the tumor and surrounding nodes 4700 cGy to the pelvis, with an integrated boost to the primary tumor and involved nodes of receiving 5400cGy in 27fx.

Cohort 2
The plan is to enroll six patients with MSI, regardless of their primary cancer diagnosis. This cohort will serve to generate hypothesis and initial data to plan a larger study. All analyses from this cohort will be exploratory
Drug: TSR-042 or Dostarlimab
Patients will be given TSR-042/Dostarlimab at a dose of 500mg IV, over 30 minutes Q 3 weeks.
Other Name: Dostarlimab




Primary Outcome Measures :
  1. Pathologic complete response (pCR) or complete clinical response (cCR) at 12 months [ Time Frame: 12 months ]
    To determine the pathologic complete response rate (pCR) or complete clinical response (cCR) rate at 12 months, after PD-1 blockade and with or without chemoradiation in subjects with mismatch repair deficient locally advanced adenocarcinoma.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Willing and able to provide written informed consent for the trial.
  • Be ≥18 years of age on the date of signing informed consent.
  • ECOG performance status of 0 or 1.
  • Histologically confirmed locally advanced solid tumor
  • Solid tumors that in standard practice would be treated with neoadjuvant therapy
  • No evidence of distant metastases.

    • Radiologically measurable or clinically evaluable disease
  • Tumor specimen that demonstrates mismatch repair deficiency by Immunohistochemistry or microsatellite instability as demonstrated by NGS or PCR.
  • Negative pregnancy test done 72 hours prior to beginning treatment, for women of childbearing potential only. Subjects of childbearing potential must be willing to use an adequate method of contraception. Appropriate methods of birth control include abstinence, oral contraceptives, implantable hormonal contraceptives, or double barrier method (diaphragm plus condom). Contraception, for the course of the study starting with the first dose of study medication through 150 days after the last dose of study medication. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

Nonchildbearing potential is defined as follows (by other than medical reasons):

  • ≥45 years of age and has not had menses for >1 year
  • Patients who have been amenorrhoeic for <2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
  • Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use 2 adequate barrier methods throughout the study.

    • Participant receiving corticosteroids may continue if their dose is stable for least 4 weeks prior to initiating protocol therapy.
    • Demonstrate adequate organ function as defined below within 14 days of Cycle 1, Day 1, all screening labs should be performed within 14 days of treatment initiation.

Exclusion Criteria:

  • Presence of metastatic or recurrent disease
  • Prior radiation therapy, chemotherapy, or surgery for tumor
