MyCustom:A Framework for Prospective and Master Protocol Trial of Precise Drug Treatment for Refractory Solid Tumors

The MyCustom study is a investigator initiated trial(IIT), prospective real-world clinical research project, a genetic biomarker-driven "basket" (tissue-type agonistic) study. The target population covers a variety of solid advanced malignant tumors, including but not limited to patients with small cell lung, gastric, prostate, bladder cancer, head and neck squamous carcinoma or lacking effective treatment after standard treatment failure.

Detailed Description

The MyCustom study is a investigator initiated trial(IIT), prospective real-world clinical research project, a genetic biomarker-driven "basket" (tissue-type agonistic) study. The target population covers a variety of solid advanced malignant tumors, including but not limited to patients with small cell lung, gastric, prostate, bladder cancer, head and neck squamous carcinoma or lacking effective treatment after standard treatment failure.The overall goal is to develop a more effective research method to test new individualized treatment hypotheses.This study will provide comprehensive theoretical and practical support for individualized custom model in refractory solid tumors.Archival pathology laboratory samples from patients with treatment-refractory advanced solid cancer of any histologic type undergo Next Gene Sequencing(NGS) analysis.Fllowing obtain the raw data of the patient's gene sequencing, the data are analyzed by the auxiliary decision algorithm to obtain the prioritization results of the drugs matched by this patient.The results are subsequently reviewed by the Molecular Tumor Board (MTB), where eligible patients can be treated in treatment substudies.All patients who receive treatment with a drug available in the protocol will be followed for standard efficacy outcomes including clinical efficacy ,clinical safety and exploratory endpoints such as biomarkers for drug response, change in the tumor microenvironment. For some clinical studies, to meet the primary objective, at least 35% of participants had to achieve a PF2S/PFS1 ≥ 1.3 in a sample population of 25 evaluable patients. sample size was calculated using an exact single-stage design for phase II studies with a one-sided type I error of 5% and a power of 90% under the assumption that PF2S/PFS1≥ 1.3 in ≤10% of patients would be clinically irrelevant, while a success rate ≥ 35% would merit further investigation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Eligible patients have an advanced or metastatic solid tumor, multiple cancers(including but not limited to small cell lung cancer, gastric cancer, prostate cancer, bladder cancer, and head and neck squamous cell carcinoma) standard treatment options are no longer available or lack effective treatments.

Description

Inclusion Criteria:

  1. Adults(≥18 years of age)with pathologically confirmed advanced or metastatic solid cancer of any histological type, or an earlier diagnosis of cancer with a poor prognosis. Suffificient accessible tissue for molecular profifiling;
  2. Patients receiving their last line of standard treatment or who have received and failed all standard anticancer therapy (if available) or are unsuitable for further standard anticancer therapy. Cancers with a poor prognosis or low expected response rate to standard treatment (as judged by the investigator on the basis of available evidence) may be screened with respect to an earlier line of treatment;
  3. ECOG performance status of 0-4(Poor performance status caused by tumor diseases(3-4));
  4. Willing and potentially able to comply with study requirements,including treatment, timing and nature of required assessments;
  5. Signed, written informed consent to participate.

Exclusion Criteria:

  1. Suitable for standard therapy;
  2. Specific contraindications to exposure to the investigationalproducts;
  3. Other comorbid conditions that may compromise assessing key outcomes or, in the judgement of the clinician, limit the ability of the patient to comply with the protocol;
  4. Symptoms and uncontrolled central nervous system (CNS) involvement in a patient with a non-central cancer;
  5. Pregnancy, lactation or inadequate contraception.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Cohort-A: Patients with actionable targets
In the OncoKB(Precision Oncology Knowledge Base) database, the gene alteration has a variant of clinical evidence in this tumor or other tumor types and is considered to be an interventional variant. Cohort-A may include different observation subgroups. For example, substudy-A1: monotherapy/combination therapy for patients with A1-relative. Substudy-Ax: monotherapy/combination therapy for patients with Ax-relative.
Cohort-B: Patients with potential actionable targets
In cohort-B, the gene alteration that MTB combines with clinical practice and literature reports that can match targeted therapy is considered to be potential actionable targets. Cohort-B also includes different observation subgroups and clinical trials may conduct in each subgroup. For example, substudy-B1(TP53 as driver gene), substudy-B2(RAS as driver gene), substudy-B3(MAP2K1 as driver gene), substudy-B4(PTEN Loss as driver gene), substudy-B5(11q13 co-amplification as driver genes), Substudy-B6(concomitant actionable alterations), substudy-B7(other driver genes). MTB-guided therapy was defined as having a clinical benefit if the PFS ratio between the longest PFS on MTB-guided therapy and the PFS on the last therapy before MTB-guided therapy was ≥1.3 (i.e., using patients as their own controls) for each substudy. To meet the primary objective, at least 35% of participants had to achieve a PF2S/PFS1 ≥ 1.3 in a sample population of 25 evaluable patients.
Cohort-C: Patients with non-actionable targets
MTB combined with clinical practice and literature reports can not match the gene alteration of targeted therapy, which is considered as an irreversible gene alteration.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PFS2/PFS1(Progression Free Survival 2/Progression Free Survival 1)
Time Frame: 3 years
The time to progression-free survival during the substudy (PFS2) exceeds the documented time to disease progression-free survival during the last treatment prior to substudy entry (PFS1) by at least 35% (ie, PFS2/PFS1≥1.3) or, if PFS1 is not evaluable, time to progressive disease exceeds 6 months.
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
ORR(Objective Response Rate)
Time Frame: 3 years
Evaluation of the best objective response rate (ORR) for each treatment according to RECIST 1.1. The best ORR is the best response reached during treatment according to RECIST 1.1 criteria.
3 years
OS(Overall Survival)
Time Frame: 3 years
Evaluation of overall survival (OS) defined as the time between inclusion and death, whatever the cause is. Alive patients will be censored at their last known contact date.
