A Trial Comparing Gemcitabine With and Without IMM-101 in Advanced Pancreatic Cancer
- Conditions
- Advanced Pancreatic Cancer
- Interventions
- Biological: IMM-101Drug: Gemcitabine
- Registration Number
- NCT01303172
- Lead Sponsor
- Immodulon Therapeutics Ltd
- Brief Summary
To compare, in patients with advanced pancreatic cancer, the effects of IMM-101 in combination with gemcitabine to gemcitabine alone on safety and tolerability (including QoL), clinical signs and symptoms of disease, selected markers of tumour burden and immunological status, and disease outcome.
- Detailed Description
Patients in the IMM 101 treated group received an initial dose of IMM-101 followed by a maximum of 12 cycles of Gemcitabine (plus IMM-101); patients in the control group received Gemcitabine alone. All patients were to receive Gemcitabine once weekly for 3 consecutive weeks out of every 4 weeks. Patients in the IMM 101 treated group were to receive IMM 101 every 2 weeks for the first 3 doses, followed by a 4 week rest, then IMM-101 every 2 weeks for the next 3 doses. After this time, patients received doses every 4 weeks. Gemcitabine treatment began at least 14 days after the first dose of IMM-101 in the IMM 101 treated group.
Patients who completed the Main Study and who provided informed consent were eligible to participate in a long term treatment Sub-Study. All patients received IMM-101 in the open-label, single arm, Sub-Study irrespective of whether they had been randomised to Gemcitabine or Gemcitabine plus IMM-101 in the main study.

- Surgical or medical condition which, in the judgement of the Investigator, might interfere with the activity of IMM-101, or with the performance of this study.
- Any uncontrolled concomitant disease (e.g. unstable angina pectoris, congestive heart failure, myocardial infarction, arrhythmias, and uncontrolled severe hypertension) which, in the judgement of the Investigator, might interfere with the activity of IMM 101, or with the performance of this study.
- A history of serious adverse reaction or serious hypersensitivity to any drug.
- Known to have a history of human immunodeficiency virus (HIV) or syphilis, current symptomatic Hepatitis B or C. Testing is not required in the absence of clinical signs and symptoms suggestive of infection with HIV.

- Arm && Interventions
Group Intervention Description IMM-101 in addition to gemcitabine IMM-101 Patients in the experimental arm will receive IMM-101 in addition to the current standard of care, namely chemotherapy (Gemcitabine). The treatment regimen with IMM-101 will be every 2 weeks for the first 3 doses followed by a rest of 4 weeks then every 2 weeks for the next 3 doses followed by every 4 weeks thereafter. For patients in the active group, chemotherapy (Gemcitabine) will begin at least 14 days after first dose of IMM-101. Chemotherapy plus IMM-101 will be offered until intolerable toxicity or withdrawal from the study up to a maximum of 12 cycles (i.e. approximately 48 weeks). Patients who complete the Main Study and who provide informed consent are eligible to participate in a long term treatment Sub-Study (IMM-101-002A) Gemcitabine chemotherapy Gemcitabine Patients in the control arm will receive normal standard of care - up to 12 cycles of Gemcitabine. Dosing of Gemcitabine is as per the normal prescribing information for pancreatic cancer.
- Primary Outcome Measures
Name Time Method Safety and Tolerability. From time of Informed Consent to 30 days post last dose of study medication A clinically relevant deleterious effect of IMM-101 on safety and tolerability profiles was judged by:
* Local and systemic toxicities.
* Number, type and degree of toxicities as measured by the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) v4.0.
Adverse events were collected from time of Informed Consent to 30 days post last dose of study medication IMM-101 does not appear to confer an incremental safety burden beyond that associated with chemotherapy and the disease itself. No new safety signals were identified from this study. The numbers of SAEs by preferred term were low, such that no trends could be inferred from these data and no significant SAEs attributable to IMM 101 were observed.
- Secondary Outcome Measures
Name Time Method Survival From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 1 year (or longer in the case of patients who entered the long term treatment sub-study, up to 5 years). Overall and progression free survival
Overall Response Rate (ORR). From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 1 year (or longer in the case of patients who entered the long term treatment sub-study). A clinically relevant improvement Overall Response Rate (ORR). Overall response rate was defined as the percentage of patients with a complete response or partial response as assessed by RECIST v1.1 criteria.
Overall Survival in Metastatic Patients Only From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 1 year (or longer in the case of patients who entered the long term treatment sub-study, up to 5 years). Overall and progression free survival in metastatic patients only
