Purpose

This is a multi-center, open-label, first-in-human Phase 1 study evaluating the anti-programmed death receptor 1 (anti-PD-1) antibody dostarlimab (also known as TSR-042) n participants with advanced solid tumors who have limited available treatment options. The study will be conducted in 2 parts with Part 1 consisting of safety evaluatation, pharmacokinetics (PK), and pharmacodynamics (PDy) of escalating doses of dostarlimab. Dose escalation will be based on ascending weight-based dose levels (DLs) of dostarlimab and will continue until the maximum tolerated dose (MTD) is reached or may be stopped at any dose level up to the highest dose of 20 milligrams per kilograms (mg/kg) based on emerging safety and PK/PDy data. Part 2 will be conducted in two subparts, Part 2A (fixed-dose safety evaluation cohorts) and Part 2B (expansion cohorts). Part 2A of the study will evaluate the safety and tolerability of dostarlimab at fixed doses of 500 mg administered every 3 weeks (Q3W) and 1000 mg administered every 6 weeks (Q6W). Part 2B of the study will examine the safety and clinical activity of dostarlimab in cohorts of participants with specific types of advanced solid tumors.

Dostarlimab will be administered intravenously (IV) on Day 1 and Day 15 of each cycle; cycle length is 28 days. Cohorts will be enrolled sequentially and will initially follow a 3+3 design.
Biological:Dostarlimab
Dostarlimab (160 mg, 20 mg/mL; or 500 mg, 50 mg/mL) is a humanized monoclonal antibody that binds with high affinity to PD-1 resulting in inhibition of binding to programmed death receptor ligands 1 and 2 (PD-L1 and PD-L2). Dostarlimab will be administered via a 30 minute IV infsusion on Day 1 and Day 15 of each cycle in Part 1. For additional patients enrolled specifically to better characterize the PK/PDy profile in Part 1, dostarlimab administration during Cycle 1 will only occur on Day 1 with the second dose administered on Cycle 2/Day 1 and Q2W thereafter. For Part 2A and 2B, dostarlimab will be administered on Day 1 of each treatment cycle. Cycle duration for Q3W dosing is 21 days and Q6W dosing is 42 days.

Experimental:Part 2A: Participants receiving dostarlimab

In Part 2A, participants will receive fixed dose of 500 mg administered Q3W or 1000 mg administered Q6W dose on Day 1 of each cycle.

  • • The criteria below should be met for participant participating in:
  • • Cohort A1 (dMMR/MSI-H endometrial cancer) and
  • • Cohort A2 (MMR-proficient/MSS endometrial cancer)
  • • Participants who have progressed on or after platinum doublet therapy
  • • Participants have received no more than 2 lines of anti-cancer therapy for recurrent or advanced (>=Stage IIIB) disease. Prior treatment with hormone therapies is acceptable and does not count towards the number of anti-cancer therapies noted in the criterion above for this cohort.
  • • All endometrial cancer histologies are allowed except endometrial sarcoma (including carcinosarcoma).
  • • Participants must submit 2 scans demonstrating increase in tumor measurement that meet criteria for PD on or after the latest systemic anti-cancer therapy based on RECIST 1.1 to Central Radiology prior to the first dose of dostarlimab.

Neoadjuvant, adjuvant, and the combination of both will be considered as 1 line of therapy. Treatment with single-agent bevacizumab given as maintenance is not counted as a separate line of therapy. If a therapeutic regimen is modified or changed for a reason other than lack of response or PD (such as allergic reaction, toxicity, or drug availability), this is not counted as a separate line of therapy. The use of single-agent hormonal therapy given for reasons other than PD per RECIST v1.1 (i.e., hormonal therapy given for increasing Cancer antigen [CA]-125 levels) is not counted as a separate line of therapy.
  • • Participants must have been previously treated with platinum-based regimen, taxane agent(s), and bevacizumab (bevacizumab could be used as a single agent or in combination with another agent, in frontline therapy, as maintenance, or for treatment of recurrent disease).
  • • Part 2B: Participants must have archival tumor tissue available that is formalin-fixed and paraffin-embedded.
  • • For participants who do not have archival tissue, a new biopsy must be performed to obtain a tissue sample prior to study treatment initiation. For participants without available archival tissue, the biopsy should be taken from the tumor lesions (either primary or metastatic) that have easy accessibility and low biopsy-associated risks and will exclude biopsies of the liver, brain, lung/mediastinum, pancreas, or endoscopic procedures extending beyond the esophagus, stomach or bowel.
  • • For Cohort G, participant must provide formalin fixed paraffin embedded (FFPE) tumor tissue block(s) with sufficient tumor content (as confirmed by the Sponsor's designated central laboratory) during screening to enable, for example, measures of homologous recombination pathway defects and PD-L1 status. The use of slides created from paraffin-embedded tissue as opposed to FFPE blocks must be approved by the Sponsor.
  • • Female participants must have a negative serum pregnancy test within 72 hours prior to the date of the first dose of study medication: unless they are of non-child bearing potential.
  • • Non child bearing potential is defined as: >= 45 years of age and has not had menses for > 1 year; Amenorrheic for < 2 years without a hysterectomy and oophorectomy and have a follicle- stimulating hormone (FSH) value in the postmenopausal range upon pre-study (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, magnetic resonance imaging (MRI) or computed tomography (CT) scan. Tubal ligation must be confirmed with medical records of the actual procedure.
  • • Female participants of childbearing potential must agree to use 1 highly effective form of contraception with their partner starting with the screening visit through 150 days after the last dose of study therapy.
  • • Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of <= 2 for Part 1 and <= 1 for Part 2.
  • • Participant has an adequate organ function.

Exclusion Criteria

  • • Participant has received prior therapy with an anti- programmed death receptor 1 (anti-PD-1), anti-PD-1- ligand-1 (anti-PD-L1), or anti-PD-1 ligand-2 (anti-PD- L2) agent.
  • • Participant has a known uncontrolled central nervous system (CNS) metastases and/or carcinomatous meningitis.
  • • Participant has a known additional malignancy that progressed or required active treatment within the last 2 years. Exceptions include basal cell carcinoma of the skin, squamous cell cancer (SqCC) of the skin that has undergone potentially curative therapy, or in situ cervical cancer.
  • • Participant is considered a poor medical risk due to a serious, uncontrolled medical disorder, nonmalignant systemic disease or active infection requiring systemic therapy. Specific examples include, but are not limited to, active, non-infectious pneumonitis; uncontrolled ventricular arrhythmia; recent (within 90 days) myocardial infarction; uncontrolled major seizure disorder; unstable spinal cord compression; superior vena cava syndrome; or any psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the study (including obtaining informed consent).
  • • Participant is pregnant or breastfeeding, or expecting to conceive children within the projected duration of the study, starting with the Screening Visit through 150 days after the last dose of study treatment.
  • • Participant has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study treatment.
  • • Participant has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies).
  • • Participant has a known active hepatitis B (eg, hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (eg, hepatitis C virus ribonucleic acid (HCV RNA) (qualitative) is detected).
  • • Participant has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease- modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Use of inhaled steroids, local injection of steroids, and steroid eye drops are allowed.
  • • Participant has as history of interstitial lung disease.
  • • Participant has not recovered (i.e., to <= Grade 1 or to Baseline) from radiation- and chemotherapy-induced AEs or received transfusion of blood products (including platelets or red blood cells) or administration of colony-stimulating factors (including granulocyte-colony stimulating factor [G-CSF], granulocyte macrophage colony-stimulating factor [GM-CSF] or recombinant erythropoietin) within 3 weeks prior to the first dose of study drug.
  • • Participant has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks prior to the first dose of study drug.
  • • Participant has received prior anti-cancer therapy (chemotherapy, targeted therapies, radiotherapy, or immunotherapy) within 21 days, or less than 5 times the half-life of the most recent therapy prior to study Day 1, whichever is shorter.
  • • Participant has not recovered adequately (<= Grade 1) from AEs and/or complications from any major surgery prior to starting therapy.
  • • Participant has received a live vaccine within 14 days of planned start of study therapy.
  • • Participant has a known hypersensitivity to dostarlimab components or excipients.
  • • For Cohort G, participants will not be eligible if they meet the following criteria:
  • • Participants who experienced disease progression within 3 months (as evidenced by radiographic progression per RECIST) of first-line platinum therapy.
  • • Participants with known deleterious or suspicious deleterious mutation in BRCA1 or BRCA2 genes (local testing permitted).
  • • Participants has received prior therapy with a poly(adenosine diphosphate-ribose) polymerase (PARP)-1/PARP-2 inhibitor.
  • • Participant has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, might interfere with the participant's participation for the full duration of the study treatment, or is not in the best interest of the participant to participate.
  • • Participant is immunocompromised. Participants with splenectomy are allowed.
