Trial Outcomes & Findings for Study of Paclitaxel Protein Bound + Gemcitabine + Cisplatin + Hydroxychloroquine as Treatment in Untreated Pancreas Cancer (NCT NCT04669197)

Study of Paclitaxel Protein Bound + Gemcitabine + Cisplatin + Hydroxychloroquine as Treatment in Untreated Pancreas Cancer

Laboratory measurements of CA 19-9, a circulating tumor biomarker, were collected on Day 1 of every treatment cycle (approximately 21 days/cycle); CA 19-9 normalization after 2 or more treatment cycles was measured.

The percentage of participants whose tumors could be completely removed by surgery after receiving study regimen with no cancer cells left at margins (R0).

Pathological complete response rate (pCR) is defined here as the absence of detectable cancer after surgical resection. Participants received a CT/MRI scan after surgical resection to monitor response using RECIST 1.1 criteria.

Objective measurement of changes in tumor size upon imaging after treatment per RECIST v1.1 criteria; percentage of participants reporting Complete Response (CR; all tumors disappear) and Partial Response (PR; \>30% decrease in tumor size).

Objective measurement of changes in tumor size upon imaging after treatment per RECIST v1.1 criteria. Complete Response (CR; all tumors disappeared), Partial Response (PR; \>30% decrease in tumor size), Stable Disease (SD; no change), and Progressive Disease (PD; \>20% increase in tumor size or new lesions).

Participants were contacted by telephone every 12 weeks to monitor survival until date of death. Participants surviving up to 2 years are reported.

Participants were contacted by telephone every 12 weeks to monitor survival until date of death.

The number of patients who experienced an adverse event (AE) determined to be related to one or more of the study agents. Adverse events occurring were graded according to the NCI Common Terminology Criteria for Adverse Events v4.0 (CTCAE). Grade refers to the severity of the AE and are given on a 1-5 scale, with each scale having unique clinical descriptions of severity for each AE based on this general guideline: Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2: Moderate; minimal, local or noninvasive intervention indicated. Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling. Grade 4: Life-threatening consequences; urgent intervention indicated. Grade 5: Death related to AE.

The Brief Pain Inventory (BPI) is a standard questionnaire administered to participants to measure cancer pain intensity and the impact of pain on daily life in the past 24 hours. Pain severity was assessed with a scale range of 0-10, 0=no pain, 10=worst imaginable. Multiple question results were combined into a single pain severity score per patient on the 0-10 scale range. Data is presented as the median of baseline scores ("Baseline") (n=11), median of end of treatment (EOT) scores ("End of Treatment (EOT)") (n=11), and median of within-subject change scores calculated as EOT minus baseline scores ("Change Between Baseline and EOT") (n=11).

The Brief Pain Inventory (BPI) is a standard questionnaire administered to participants to measure cancer pain intensity and the impact of pain on daily life in the past 24 hours. Pain interference was assessed with a scale range of 0-10, 0=does not interfere, 10=completely interferes. Multiple question results were combined into a single pain interference score per patient on the 0-10 scale range. Data is presented as the median of baseline scores ("Baseline") (n=11), median of end of treatment (EOT) scores ("End of Treatment (EOT)") (n=11), and median of within-subject change scores calculated as EOT minus baseline scores ("Change Between Baseline and EOT") (n=11).

The MD Anderson Symptom Inventory for Gastrointestinal Cancer (MDASI-GI) is a questionnaire designed to assess the severity and impact of cancer symptoms on daily life activities. Core symptom severity within the last 24 hours was assessed with a scale range of 0-10, 0=not present, 10=worst imaginable. The reported severity of multiple symptoms was combined into a single overall symptom severity score for each patient on the 0-10 scale range. Data is presented as the median of baseline scores ("Baseline") (n=11), median of end of treatment (EOT) scores ("End of Treatment (EOT)") (n=11), and median of within-subject change scores calculated as EOT minus baseline scores ("Change Between Baseline and EOT") (n=11).

The MD Anderson Symptom Inventory for Gastrointestinal Cancer (MDASI-GI) is a questionnaire designed to assess the severity and impact of cancer symptoms on daily life activities. The GI module asks specific questions related to GI symptoms and asks users to rank the severity of symptoms using a 0-10 scale, 0=not present, 10=worst imaginable. The reported severity of multiple GI symptoms was combined into a single GI module score for each patient on the 0-10 scale range. Data is presented as the median of baseline scores ("Baseline") (n=11), median of end of treatment (EOT) scores ("End of Treatment (EOT)") (n=11), and median of within-subject change scores calculated as EOT minus baseline scores ("Change Between Baseline and EOT") (n=11).

The MD Anderson Symptom Inventory for Gastrointestinal Cancer (MDASI-GI) is a questionnaire designed to assess the severity and impact of cancer symptoms on daily life activities. Symptom interference with daily life activities within the last 24 hours was measured using a 0-10 scale, 0=does not interfere, 10=interferes completely. The reported interference for multiple daily activities was combined into a single symptom interference score for each patient on the 0-10 scale range. Data is presented as the median of baseline scores ("Baseline") (n=11), median of end of treatment (EOT) scores ("End of Treatment (EOT)") (n=11), and median of within-subject change scores calculated as EOT minus baseline scores ("Change Between Baseline and EOT") (n=11).
