Study summary

Pancreatic cancer represents the most lethal of the common malignancies with a 5-year survival rate of less than 5%. For patients who are eligible for potentially curative resection, despite mortality and morbidity rates after surgery have improved, the recurrence rate is up to 85% within 2 years. FOLFIRINOX (fluoropyrimidine/leucovorin plus irinotecan and oxaliplatin) has been proved to significantly improve the prognosis and is recommended as first line treatment in patients with advanced pancreatic cancer. However, the regimen is limited due to the severe adverse effects. Thus, the investigators replaced 5-FU and leucovorin in the FOLFIRINOX regimen with oral S-1, a new oral fluoropyrimidine derivative which was proved to be the well-tolerated and effectively in large III phase randomized clinical trial, to form the SIRIOX regimen. A phase I clinical trial from Japan found that SOXIRI (S-1, oxaliplatin and irinotecan) works in patients with advanced pancreatic cancer. In this study, the researchers intend to investigate the activity and safety of the combination of this regimen in patients with advanced pancreatic cancer, as first- or second-line chemotherapy.

Read the detailed description

Pancreatic cancer (mainly pancreatic ductal adenocarcinoma, PDAC) is a disease with extremely poor prognosis, and is often fatal. Surgical resection is the only potentially curative technique for management of PDAC, but only approximately 15% to 20% of patients are candidates for pancreatectomy at the time of diagnosis Gemcitabine (Gem) is widely used as a standard chemotherapeutic agent for advanced pancreatic cancer. FOLFIRINOX (fluoropyrimidine/leucovorin plus irinotecan and oxaliplatin), compared with Gem, has been proved to significantly improve the objective response rate (31.6% VS. 9.4%, P \< 0.001) and prolong the median survival time (11.1 months VS. 6.8 months, P \< 0.001) for patients with metastatic pancreatic ductal adenocarcinoma(PDAC), who had a performance status of ECOG 0-1 score. However, it is undeniable that the adverse effects of FOLFIRINOX are severe. For example, the incidence of 3/4 grade neutrophil decrease in patients receiving FOLFIRINOX is significantly higher than those with Gem (45.7% VS. 21%, P \< 0.001). Thus, it is difficult for many patients to receive standard FOLFIRINOX and benefit from the protocol. Therefore, the investigators aim to explore an improvement program of FOLFIRINOX, hoping to better benefit patients.

S-1 is a new oral fluoropyrimidine derivative in which tegafur is combined with two 5-chloro-2, 4-dihydroxypyridine modulators and oteracil potassium, a potentiator of 5-fluorouracil's (5-FU's) antitumor activity that also decreases gastrointestinal toxicity. Combination chemotherapy with Gem and S-1 is reportedly well tolerated and benefits patients with advanced PDAC. Based on the results of the GEST study, S-1 is found to be non-inferior to Gem in patients' survival.

Therefore, in this study, the investigators replaced 5-FU and leucovorin in the FOLFIRINOX regimen with oral S-1, forming a SIRIOX regimen to treat patients with advanced pancreatic cancer, as first- or second-line chemotherapy.

Terms in these criteria, in plain language(23)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. progression free survival (PFS)

    The time from the beginning of randomization to the earliest date of confirmation of tumor progression or the patient death for any reason. If the above criteria are not reached, the date of the last evaluation will be used.

    Time frame: 6 weeks (1.5 cycle)

Secondary outcomes

  1. objective response rate (ORR)

    The proportion of patients whose tumors shrink to a certain amount for a certain period of time and include cases of complete response (CR) and partial response (PR). Calculated as: (CR cases + PR cases) / FAS × 100 (%); FAS (full analysis set) refers to the case of qualified patients, administered more than one case. Tumor remission rates are calculated according to the RECIST guidelines (version 1.1)

    Time frame: 6 weeks (1.5 cycle)

  2. overall survival (OS)

    The time from the beginning of randomization to the earliest date of confirmation of the patient death for any reason.

    Time frame: through study completion, an average of 18 months

  3. Toxicity evaluated according to the Common Terminology Criteria Adverse Events

    Toxicity is evaluated according to the Common Terminology Criteria Adverse Events Version3.0,CTCAEv3.0

    Time frame: every week
