The aim of the study is to compare the efficacy and toxicity of full-dose Gemcitabine and reduced-dose combination chemotherapy in patients with non-resectable pancreatic cancer, who are unfit for full-dose combination chemotherapy.

The patients will be equally randomized to arm A or arm B:

Arm A: Full-dose single agent treatment with Gemcitabine 1000 mg/m2 weekly on days 1, 8,and 15 every 4 weeks.

Arm B: Reduced-dose (80%) combination-treatment with Gemcitabine plus Nab-Paclitaxel (Gemcitabine: 800 mg/m2 plus Nab-Paclitaxel: 100 mg/m2 on day 1, 8 and 15 every 4 weeks)

Progression-free survival, overall survival and response rate will be estimated for each group, as well as toxicity and quality of life will be prospectively registered.

According to guidelines the recommended treatment for patients with non-resectable pancreatic cancer (PC) is combination chemotherapy, whereas old and/or fragile patients can be offered Gemcitabine monotherapy, if they are fit for treatment. Phase III trials show improved effect of combination chemotherapy compared to Gemcitabine, but these trials were restricted to fit patients younger than 75 years of age, as full-dose combination chemotherapy is more toxic.

Studies in colorectal cancer and a post-hoc analysis of Gemcitabine plus Nab-Paclitaxel in PC suggest that reduced-dose of combination chemotherapy may be more efficient in terms of progression-free survival and less toxic as compared to monotherapy in elderly and/or frail patients, but reduced start-dosing of GemNab is not currently labelled.

Moreover, a recent Danish register-based study showed that more use of combination chemotherapy at oncological departments was associated with improved outcome of patients with PC.

Elderly and frail patients with PC are in great need of better treatment results. Hence, a comparative study of reduced-dose combination chemotherapy is warranted and may be practice changing.

The aim of the study is to compare the efficacy and toxicity of full-dose Gemcitabine and reduced-dose combination chemotherapy in patients with non-resectable PC, who are unfit for full-dose combination chemotherapy.

The study is a national multicenter prospective randomized phase II trial, endorsed by the Danish Pancreas Cancer Group (DPCG). 98 patients with non-resectable PC, unfit for full-dose combination chemotherapy, but eligible for first-line chemotherapy, will be included.

The patients will be equally randomized to arm A or arm B:

Arm A: Full-dose single agent treatment with Gemcitabine 1000 mg/m2 weekly on days 1, 8 and 15 every 4 weeks.

Arm B: Reduced-dose (80%) combination-treatment with GemNab (Gemcitabine: 800 mg/m2 plus Nab-Paclitaxel: 100 mg/m2 on day 1, 8 and 15 every 4 weeks).

Progression-free survival, overall survival and response rate will be estimated for each group, as well as toxicity and quality of life will be prospectively registered.

Gemcitabine Versus Reduced-dose Combination Chemotherapy in Fragile Patients With Non-resectable Pancreatic Cancer

A Randomized Phase II Study of Gemcitabine Versus Reduced-dose Combination Chemotherapy in Fragile Patients With Non-resectable Pancreatic Cancer

PFS is defined in the ITT population as the date of the randomization to the date of disease progression or date of death, whichever comes first. The date of PD is the date of scan, if progression is found on a CT scan, or date of visit at which clinical progression is found. PD at CT is defined according to RECIST version 1.1.

OS is defined in the ITT population as the date of randomization to date of death of all causes.

In patients with measurable disease at baseline, RECIST version 1.1 will be used for evaluation of complete response (CR), partial response (PR), stable disease (SD) or PD. ORR will be calculated as the percentage of patients with CR+PR of all patients with measurable disease, who received at least one treatment and were evaluated by at least one diagnostic CT scan.

The total number of hospital admissions in a stationary unit with overnight stay from the start of treatment to the date of end of treatment will be assessed in the treated population. If the patient is readmitted for the same reason within 3 days (e.g., after weekend leave), this is not counted as a separate admission. The reasons for admission are registered as toxicity due to treatment or symptoms due to PC. The sum of hospitalizations is calculated for each randomization arm for comparison.

QoL scores collected will be linearly transformed to a scale of 0 to 100. Items will be grouped in health status scale (range 0 - 100, high is better), functional scales (range 0 - 100, high is better) and symptom scales (range 0 - 100, low is better). Each scale is summarized by its mean, and standard deviation for the patients in the two treatment groups. The difference in mean at 8, 16 and 24 weeks are compared with the baseline mean within in each treatment groups. The difference in mean between the treatment groups are compared at baseline, 8, 16 and 12 weeks.

(Adverse events ≥ grade 3 according to CTCAE version 5.0). All patients who have received 1 dose of chemotherapy will be calculated in the safety analyses. Cumulative worst toxicities ≥CTC grade 3 in the treated population are registered for each arm separately for comparison.
