Study Description

Brief Summary:

The purpose of this study is to determine the effectiveness of a regimen of selected metabolic treatments for patients with cancer in a real world setting and to conduct exploratory analysis on the relationship between the degree of response and changes in biochemical markers (such as glucose and lipid levels).

Condition or disease	Intervention/treatment	Phase
Cancer; Overall Survival	Drug: Metabolic treatment	Phase 3

Detailed Description:

*This study has been designed to collect data prospectively and to retrospectively analyse data on the metabolic treatments within the cancer clinic. The retrospective study is ongoing, while the prospective study has not yet started.*

This is a real world study since this gives the best opportunity to properly examine the effect of multi-drug regimens in representative populations. Including a standard of care arm is inappropriate, in a population in which that standard of care has already been shown to be ineffective or intolerable.

Patients will be sent to the study clinic directly by their Health Care Professionals ("HCP's") .

The study will consist of a pre-screening visit to determine eligibility for inclusion into the study, an initiation visit and then a follow up visit every three months thereafter. If required, unscheduled visits may take place. Day 0 (baseline) for each patient will be the initiation visit when study treatment is started.

Prior to conducting any study-related procedures, subjects will provide written informed consent, eligibility will be assessed, a medical history and past medical records will be taken and vital signs will be measured. These records will include the stage of their disease, response to previous cancer therapy, their prior and current medications and any specific regimen they are currently on for their cancer. If prior medical records do not contain sufficient information to determine a baseline for the patient, additional blood tests and scans will be undertaken as appropriate.

Patients will be monitored quarterly thereafter when blood tests (e.g. safety parameters, glucose, cholesterol, immune response and cancer markers where applicable) and scans (where applicable) will be taken.

All patients will be on the same drug regimen (see below) at the same doses throughout the study. All patients will be followed up until they choose to leave the study, or death.

Data from all patients recruited to the study will be analysed using an Intention-to-treat (ITT) philosophy, so data will be included in the primary analysis irrespective of whether the dose regimen was followed throughout the study. If appropriate, and numbers allow, analysis will also be conducted on the Per Protocol population, comprising those patients who adhere to the regimen as prescribed.

Survival analysis methods will be used to estimate the Overall survival associated with the study regimen for each type of cancer. These estimates will be interpreted in the light of data obtained from the literature, and from eliciting expert opinion. Bayesian methods may be used where appropriate.

Tumour response, where applicable, will be summarised in tables and graphs. Estimates of response rates will be presented for each cancer type with confidence intervals.

The relationship between changes in biochemistry values (glucose, lipids) and efficacy outcomes (Progression Free Survival (PFS), Overall Survival (OS) and HRQoL) will be investigated graphically, or using other methods as appropriate.

Further exploratory analysis to investigate the effects of other factors such as age , ethnic backgrounds , cancer stage, and response to prior therapy, will also be conducted in order to try and characterise the profile of patients most likely to benefit from the study regimen.

The characteristics of patients on the regimen and those who do not stay on the regimen, for whatever reason, will be summarised to see whether there is any observed bias. If appropriate, methods will be used to adjust for any observed bias, for example using propensity scores. OS can then be assessed adjusted for this to try and mitigate for any possible risk of bias which can occur in uncontrolled studies. Furthermore, by enrolling all eligible patients over a specified time frame, it is hoped that the risk of bias should be further reduced. In addition, a large number of patients are expected to participate in the study.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Metabolic Treatment; Subjects will take the following treatments and have their data collected from their medical records every 3 months.; Oral atorvastatin up to 80mg uid, for study duration.; Oral metformin up to 1000mg uid, increased to bid if tolerated after 2 weeks, for study duration.; Oral doxycycline 100mg uid, for study duration.; Oral Mebendazole 100mg uid, for study duration.

Drug: Metabolic treatment; While subjects are being treated with the four metabolic drugs, every 3 months they will bring in their medical records and data will be collected to determine the effect of the intervention; Other Names: Metformin; Atorvastatin; Doxycycline; Mebendazole

Outcome Measures

Primary Outcome Measures :

1. Overall survival [ Time Frame: up to 5 years ]
   Overall survival for all cancer types and for each cancer type (years and months)

Secondary Outcome Measures :

1. Change in primary tumour size cancer types and by cancer type. [ Time Frame: up to 5 years ]
   Tumour size for all cancer types and for each cancer type. Units of size vary depending on cancer type.
2. Change in tumour spread (metastasis) [ Time Frame: up to 5 years ]
   Tumour spread (metastasized) to other tissues/organs, for all cancer types and for each cancer type. This is measured as either 0 for no spread or 1 for confirmed spread.
3. Change in tumour number [ Time Frame: up to 5 years ]
   Tumour number for all cancer types and for each cancer type
4. Change in cancer biomarkers (blood, urine or biopsy) [ Time Frame: up to 5 years ]
   Cancer biomarkers for all cancer types and for each cancer type. Units of measurement vary depending on the cancer type. When biomarkers, either alone or in combination with other biomarkers, are raised above normal they are seen as predictive of cancer of progression. If returned to normal are indicative of treatment response.

Other Outcome Measures:

1. Incidence of treatment related adverse events [ Time Frame: 5 years ]

   Adverse events reported by the subject or their HCP.

   • Quarterly assessment of routine laboratory tests

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 85 Years (Adult, Older Adult)
