The investigators evaluated the incidence of BRCA loss in patients with advanced gastric cancer and observed the treatment outcome and prognosis according to BRCA loss. And the investigators evaluated the possibility of BRCA loss as a predictive and prognostic factor.

Stomach cancer is still the leading cause of cancer deaths globally and is reported to be the second leading cause of cancer deaths in Korea (18.7%). Although the number of radical resection has increased due to the development of early diagnosis, many patients experience recurrence after radical resection. It is also diagnosed as a non - resectable disease locally advanced at the time of initial diagnosis, or with a metastasis. In patients with recurrent / metastatic gastric cancer, conventional palliative chemotherapy is the best treatment, and in advanced gastric cancer, combination therapy with fluoropyrimidine (fluorouracil, capecitabine, S1) and platinum (oxaliplatin, cisplatin). The progression-free survival was 3-5 months, and overall survival of 6-10 months in metastatic gastric cancer patients.

The investigators evaluated the incidence of BRCA loss in patients with advanced gastric cancer and observed the treatment outcome and prognosis according to BRCA loss. And the investigators evaluated the possibility of BRCA loss as a predictive and prognostic factor.

Anna C Couvillon, C.R.N.P.

Fatima H Karzai, M.D.

For more information at the NIH Clinical Center contact Office of Patient Recruitment (OPR)

Background:

Research studies have shown that genetic changes and family history may increase a man s risk for prostate cancer. Researchers want to follow the prostate health of men who have specific genetic changes associated with prostate cancer to help them learn more about which men are at higher risk for prostate cancer.

Objectives:

To study men with specific genetic changes and determine who is at higher risk for getting prostate cancer. To study if certain genetic changes and family history can be used to help prevent or treat prostate cancer.

Eligibility:

Persons assigned male at birth ages 30-75 who have one or more specific genetic changes but without prostate cancer.

Design:

* This study does not perform genetic testing. All participants must have documented genetic changes and able to provide a copy of the report.
* Before enrollment, participants will provide a copy of documented genetic changes and go through a telephone interview to determine eligibility for the study.
* On enrollment, participants will have medical and family history review, medication review, physical exam, blood collection for clinical and research testing, and MRI (magnetic resonance imaging) of the prostate.
* Every year, participants will repeat the physical exam, medical history, family history, medication review, routine blood tests, including PSA and testosterone.
* Every 2 years, participants will repeat all the above plus prostate MRI and blood tests for research.
* If, at any time, the physical exam, blood tests or MRI are abnormal, participants may be asked to do a biopsy.
* If the biopsy results in prostate cancer, participants will be given counseling on next steps, general treatment recommendations, and then followed with a phone call each year.
* Participants may ask to speak with a genetic counselor.

Background:

Prostate cancer is the most common malignancy and the second leading cause of cancer-related deaths in American men.

Prostate cancer has substantial inherited predisposition and certain genetic variants that are associated with an increased risk of prostate cancer.

An evolving approach to prostate cancer screening is to target populations at risk of developing prostate cancer based on their genetic predisposition.

Objective:

To follow the natural history of men with known germline variants or likely pathogenic variants in genes that put them at risk for developing prostate cancer.

Eligibility:

Persons assigned male at birth who are between ages 30-75 years old.

Documented germline pathogenic or likely pathogenic variants in prostate cancer-related risk gene: BRCA 1 and 2, DNA Mismatch Repair (MMR) genes associated with Lynch syndrome (MLH1, MSH2, MSH6, PMS2, and EPCAM), HOXB13, ATM, NBN, TP53, CHEK2, PALB2, RAD51C, RAD51D, BRIP1, or FANC (FANCA, FANCB, FANCC, FANCD2, FANCE, FANCF, FANCG, FANCI, FANCL, and FANCM).

Must be able and willing to provide informed consent.

Design:

Up to 500 subjects will be enrolled.

Participants will undergo sampling of blood for prostate-specific antigen. Based on these results and age, participants will be considered for biopsy and/or continued monitoring if feasible upon clinical discretion.

Participants will undergo a baseline MRI evaluation with follow-up scans every 2 years as clinically indicated.

Following initial evaluation, participants will be followed as clinically indicated, usually at 12 month intervals, to determine their PSA level, prostate cancer treatment (if relevant) and/or disease/survival status until death.

DOR = time from first radiographic documentation of OR (PR or CR) till radiographic disease progression (PD) as per RECIST v1.1 by investigator assessment or to death due to any cause, whichever was first. RECIST 1.1, a) target lesion (TL): CR= disappearance of all non-nodal TL, target lymph nodes reduce to \<10 mm in short axis, PR= at least 30% decrease in sum of diameters of TL, compared to the sum at baseline, PD= at least 20% increase in sum of TL measurements, compared to smallest sum on study including baseline, absolute increase in sum has to be at least 5 mm; b) for non-TL: CR= disappearance of all non-TL, PD= unequivocal progression of non-TL, such that treatment has failed, disease is progressing, regardless of status of TL; c) PD =and/or appearance of \>=1 new lesions. DOR = (earliest date of progression, death, or censoring-date of first documented OR + 1)/30.4375. Analysis was performed by Kaplan-Meier method.

EORTC QLQ-C30: cancer-specific instrument with 30 questions to assess the participant QoL. First 28 questions used to evaluate 5 functional scales (physical, role, cognitive, emotional, social), 3 symptom scales (fatigue, nausea and vomiting, pain) and other single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Each question assessed on 4-point scale (1= not at all, 2= a little, 3= quite a bit, 4= very much); functional scales: higher score = better level of functioning; symptom scale: higher score = more severe symptoms; for single items: higher score= more severe problem. Last 2 questions used to evaluate global health status (GHS)/QoL. Each question was assessed on 7-point scale (1= very poor to 7= excellent). Scores averaged, transformed to 0-100 scale; higher score=better quality of life/better level of functioning. Change from baseline was calculated by subtracting the baseline value from the average value of Week 4 to 160.

TTD in global health status (GHS)/QoL=time (in months) from randomization to the first observation with \>=10 point decrease and no subsequent observations with\<10 point decrease from baseline in GHS/QoL score based on EORTC-QLQ-C30. EORTC QLQ-C30 is a cancer-specific instrument with 30 questions to assess participant quality of life. Question 29 and 30 were used to evaluate GHS/QoL. Each question was assessed on a 7-point scale (1=very poor to 7=excellent). Scores averaged, transformed to 0-100 scale; higher score=better quality of life/better level of functioning.

TTD was defined as the time (in months) from randomization to the first observation with a\>=10 point increase and no subsequent observations with a \<10 point increase from baseline in breast symptom score based on the EORTC-QLQ-BR23. EORTC-QLQ-BR23 is a disease-specific module for breast cancer developed as a supplement for the EORTC-QLQ-C30 to assess the quality of life of participants with breast cancer. EORTC-QLQ-BR23 symptoms subscale includes 4 items: systemic therapy side effects, breast symptoms, arm symptoms, upset by hair loss. Each item is rated by choosing 1 of 4 possible responses that record the level of intensity (1= not at all, 2= a little, 3= quite a bit, and 4= very much), higher scores=high level of symptom/problems.

IRF assessed PFS was defined as time (in months) from randomization until the date of first documented radiologic progressive disease per response evaluation criteria in solid tumors (RECIST) version 1.1 or death from any cause, whichever occurs first. As per RECIST v1.1, progression defined as 1) for target lesions: at least a 20% increase in the sum of target lesion measurements, compared to the smallest sum on study (including baseline), the absolute increase in the sum has to be at least 5 millimeter (mm); 2) for non-target lesions: unequivocal progression of non-target lesions, evaluated as a whole, such that it is clear that treatment has failed and disease is progressing, regardless of the status of the target lesions; 3) and/or appearance of one or more new lesions. The analysis was performed by Kaplan-Meier method.

Investigator assessed objective response was defined as the percentage of participants with a partial response (PR) or complete response (CR) as defined by RECIST v1.1. For target lesions: 1) CR: disappearance of all non-nodal target lesions. Target lymph nodes must reduce to less than 10 mm in short axis. 2) PR: At least a 30% decrease in the sum of diameters of target lesions, compared to the sum at baseline. For non-target lesions, CR: disappearance of all non-target lesions. Percentage of participants with objective response reported are based upon unconfirmed CR/PR.

OS was defined as the time (in months) from randomization to death due to any cause. If death was not observed at the time of study cut-off date or permanently lost to follow-up, OS was censored at the date the participant was last known to be alive on or before the study cut-off date, whichever was earlier. The analysis was performed by Kaplan-Meier method.

A predose PK sample was considered dose-compliant based on the following criteria: A participant must have received 21 consecutive days of 1 mg talazoparib without dosing interruption prior to sample collection; and the predose PK sample must have been collected 24 hours +/- 10 percent (2 hours and 24 minutes) after the previous day's dose and no more than 5 minutes (0.083 hours) after the administration of the dose on the day of PK sample collection.

An adverse events (AE) was any untoward medical occurrence (e.g., sign, symptom, illness, disease or injury) in a participant administered study drug or other protocol-imposed intervention, regardless of attribution. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug or the day before initiation of a new antineoplastic therapy or 30 days after the date of the last dose date of study drug, whichever occurred first, that were absent before treatment or that worsened relative to pretreatment state. AEs included both SAEs and all non-SAEs.

Toxicity grades were evaluated based on as National Cancer Institute Common Toxicity Criteria for Adverse Events Version 4.03 (NCI CTCAE v4.03). NCI CTCAE v4.03 defined the severity grade as: grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (potentially life threatening) and grade 5 (death related to AE) for each parameter. Key hematology parameters included hemoglobin (gram per liter \[g/L\]), leukocytes (10\^6 cells per liter), lymphocytes (10\^6 cells per liter), neutrophils (10\^6 cells per liter), and platelets (10\^9 cells per liter). Low value indicated lower values than the baseline values and high value indicated higher values than the baseline values. Only those categories in which at least 1 participant had data were reported.

A Phase 1b/2 Open Label, Dose Escalation and Expansion Study of the Glutaminase Inhibitor CB-839 in Combination With the PARP Inhibitor Talazoparib in Patients With Advanced or Metastatic Solid Tumors

AEs were grades as assessed by CTCAE v 5.0. A TEAE is defined as any AE occurring on or after the first dose of study drug, or existing events that worsened after the first dose during the study, up to 28 days after the last dose.

An AE is considered "related" if the investigator assessed the relationship as "possibly related" or "probably related." Disease progression includes events in the preferred terms of disease progression and malignant neoplasm progression. Grade 5 disease progression events are excluded from this table.

Hematology parameters conducted included red blood cell (RBC) count, hematocrit, hemoglobin, mean corpuscular volume (MCV), platelet count, white blood cell (WBC) count, neutrophils, lymphocytes, monocytes, eosinophils, and basophils, performed at the discretion of the investigator. Clinical chemistry parameters included aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, albumin, total protein, blood urea nitrogen (BUN), creatinine, sodium, potassium, chloride, calcium, carbon dioxide, glucose, and lactate dehydrogenase (LDH), performed at the discretion of the investigator.

A DLT was defined as an AE determined by the investigator to be possibly or probably related to study drug that also was:

* Any ≥ Grade (Gr) 4 non-hematological toxicity
* Gr 3 non-hematologic toxicity, except: fatigue; nausea/vomiting that responds within 24 hours after initiating maximal supportive care; rash or itching that resolves to ≤ Gr 1 within 2 weeks.
* Any clinically meaningful Gr 3 non-hematologic laboratory value if medical intervention is required OR the abnormality leads to hospitalization, OR the abnormality persists for \> 1 week (except Gr 3/4 elevation in serum amylase and/or lipase not associated with clinical or radiological evidence of pancreatitis).
* Gr ≥ 3 febrile neutropenia
* Gr ≥ 4 anemia; neutropenia lasting \> 7 days; thrombocytopenia
* Gr 3 thrombocytopenia associated with: a bleeding event that requires a platelet transfusion OR a life-threatening bleeding event occurring due to low platelet count which results in urgent intervention.

ORR was defined by Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 as the percentage of participants with documented complete response (CR) or partial response (PR) since the date of treatment initiation. CR=Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR=At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable disease must have been a minimum of 51 days from date of treatment initiation. Exact binomial confidence intervals (Clopper Pearson).

Overall Response Rate is defined by RECIST v1.1 as the percentage of participants with documented confirmed CR or confirmed PR since the date of treatment initiation. CR=Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR=At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. CR or PR must have been sustained a minimum of 28 days when confirmation was reported. Stable disease must have been a minimum of 51 days from date of treatment initiation. Exact binomial confidence intervals (Clopper Pearson).

Clinical Benefit Rate is defined by RECIST v1.1 as the percentage of participants with documented CR, PR, or stable disease (SD) since the date of treatment initiation. CR=Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR=At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. CR or PR must have been sustained a minimum of 28 days when confirmation was reported. SD=Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diameters while on study. SD must have been a minimum of 102 days from date of treatment initiation and documented on at least 2 consecutive post-baseline scans. Exact binomial confidence intervals (Clopper Pearson).
