Study of AG-270 in Participants With Advanced Solid Tumors or Lymphoma With MTAP Loss

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the safety, pharmacokinetics, pharmacodynamics, and clinical activity of AG-270 in participants with advanced solid tumors or lymphoma with homozygous MTAP deletion.

Detailed Description
-----------------
The purpose of this Phase 1, multicenter, open-label study is to determine the maximum tolerated dose (MTD) of AG-270, administered as a single agent or in combination with taxane-based chemotherapy, and to characterize its dose-limiting toxicities (DLTs) when given daily by mouth to participants with advanced solid tumors or lymphoma with homozygous deletion of methylthioadenosine phosphorylase (MTAP). In each arm of the study, successive cohorts of participants will receive increasing oral doses of AG-270 to determine the MTD, the dose with maximum pharmacologic activity or the maximum feasible dose, as a single agent and in combination with taxane-based chemotherapy. In the subsequent dose-expansion parts of the study, additional participants in each treatment arm will be treated at the MTD (or one of the described alternative doses) to further characterize that dose's safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD), and to detect preliminary evidence of anti-tumor activity.

Eligibility Criteria
-----------------
Inclusion Criteria: AG-270 Monotherapy Be ≥18 years of age; Have a histologically confirmed diagnosis of an advanced solid tumor or lymphoma that has progressed in spite of at least one prior line of treatment, and for which additional effective standard therapy is not available. For this study, effective standard therapy is defined as treatment that has been shown to be curative and/or to prolong survival. In addition, participants who are considered to not be candidates for standard therapy or who decline standard therapy are eligible for this study; in such cases, documentation of the reason for omitting or declining a standard therapy is required; Have evidence of homozygous loss of cyclin-dependent kinase inhibitor 2A (CDKN2A) and/or MTAP in the participant's tumor tissue; Have disease that can be clinically evaluated for improvement or progression. In the dose-expansion phase of the study arm, participants must have disease that is measurable, as defined by the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 criteria for solid tumors (Eisenhauer et al, 2009) or the Lugano criteria for lymphoma (Cheson et al, 2014); Have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of ≤2; Have a hemoglobin ≥9.0 grams per deciliter (g/dL) without red blood cell transfusion for ≥1 month; Have an absolute neutrophil count (ANC) ≥1.0 × 10^9/liter (L); Have a platelet count ≥75 × 10^9/L; Have a serum total bilirubin ≤1.5 × upper limit of normal (ULN); Have an alanine aminotransferase (ALT) ≤3.0 × ULN. (Note: There are no specific requirements for aspartate aminotransferase (AST) or Alkaline phosphatase [ALP]); Have a serum creatinine ≤1.5 × ULN; Be fully recovered from major surgery and from the acute toxic effects of prior chemotherapy and radiotherapy. Residual chronic toxicities of prior therapy ≤Grade 2 (eg, peripheral neuropathy, residual alopecia) are allowed; Female participants who are pre-menopausal or have experienced menopause for less than 2 years and who have not undergone a hysterectomy, bilateral oophorectomy, or tubal occlusion must have a negative serum pregnancy test during screening and a serum or urine pregnancy test must be re-confirmed as negative no more than 72 hours before starting AG-270. Females of reproductive potential as well as fertile men with partners who are female of reproductive potential must agree to abstain from sexual intercourse or to use 2 effective forms of contraception (including at least 1 barrier form) from the time of giving informed consent, during the study, and for 6 months (for females) and for 3 months (for males) following the last dose of AG-270. Effective forms of contraception are defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, double-barrier methods (eg, synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel), or male partner sterilization; Able to understand and has provided written informed consent. A legally authorized representative may consent on behalf of a participant who is otherwise unable to provide informed consent, if acceptable to and approved by the site and/or site's Institutional Review Board (IRB)/Independent Ethics Committee (IEC).
