A Platform Study of Novel Agents in Combination With Radiotherapy in NSCLC

Study Overview
=================
Brief Summary
-----------------
CONCORDE is a multi-institution, multi-arm, Phase IB study that will determine the recommended phase II dose (RP2D) and safety profiles of different DNA damage repair inhibitors (DDRis) when given in an open label fashion in combination with fixed dose curative intent radiotherapy (RT) in patients with stage IIB/IIIA/IIIB NSCLC. The RP2D will be evaluated by incorporating the number of observed dose limiting toxicities (DLTs) into a time to event continuous reassessment method (TiTE- CRM) model within each of the experimental arms. TiTE-CRM is used here to take into account longer-term toxicities up to 13.5 months post start of radiotherapy and use these to inform dose escalation decision making.

Detailed Description
-----------------
Radiotherapy is an effective treatment for patients with non-small cell lung cancer (NSCLC) that has not spread beyond the chest area. Radiotherapy is used as a curative treatment but unfortunately for most patients the cancer can return. Radiotherapy kills cells by damaging their DNA. Cells have the ability to repair that damage, especially the cells of normal tissue. If DNA repair can be prevented radiotherapy should be more effective causing the cancer cells to die. The study will use new drugs that affect how cells repair DNA damage, called DNA damage response inhibitors (DDRi). These will be given together with radiotherapy to hopefully improve the effectiveness of radiotherapy. The study will try to find out the most effective and safe dose of this combination treatment. There will be a clinical trial where patients due to have radiotherapy, with the hope of successful treatment that could lead to cure from their cancer or extension of life, will be offered entry onto the study. All patients will receive their radiotherapy, with 3 out of every 4 people also receiving a single DDRi drug alongside this. Both patients and study doctors will know prior to the start of the actual treatment whether a DDRi will be given, and if so which one; no placebos will be used. The patients will be followed closely to check for side effects and to assess how their cancer is responding to treatment. Blood samples will be taken to monitor treatment progress and to try to predict which patients are most likely to benefit from this type of combined treatment.

Received a prior autologous or allogeneic organ or tissue transplantation.

Grade 2 or higher peripheral sensory neuropathy. Known positive test for human immunodeficiency virus (HIV), active hepatitis B or C infection (new test not mandated for trial entry). Positive pregnancy test (at eligibility assessment for women of childbearing potential) or breast-feeding women. Patients with persistent toxicities (>CTCAE grade 2) caused by previous cancer therapy, excluding alopecia. Patients with myelodysplastic syndrome/acute myeloid leukaemia or with features suggestive of MDS/AML. Major surgery within 2 weeks of confirmation of eligibility. Patients considered a poor medical risk by the investigator due to a serious, uncontrolled medical disorder, non-malignant system disease or active uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, uncontrolled hypertension, uncontrolled atrial fibrillation, active bleeding, recent (within 3 months) myocardial infarction, major seizure, active COVID-19, any psychiatric disorder that prohibits obtaining informed consent. Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease (eg, ulcerative colitis or Crohn's disease), systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome (granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc)). The following are exceptions to this criterion: Patients with vitiligo or alopecia. Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement Any chronic skin condition that does not require systemic therapy. Patients without active disease in the last 5 years at enrolment may be included but only after consultation with the CI/Study arm-lead. Patients with coeliac disease controlled by diet alone.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The trial is designed as a randomised Phase I dose escalation platform study, using the TiTE CRM design to find the RP2D of each DDRi with RT combination. At the time of patient identification the treating centre will be informed of the allocated study arm following a pre-specified prioritisation schedule. Consenting participants will be randomised between DDRi with RT or RT only. Patients are not randomised between experimental arms nor will endpoints be compared between experimental arms. RT only participants will be pooled across the platform to provide contemporary data on toxicity.
Masking: None (Open Label)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dose limiting Toxicities | Dose-limiting toxicities (DLTs), within 13.5 months of starting radiotherapy, in order to establish the Recommended Phase II Dose (RP2D) of each DDRi-RT combination. | 13.5 months after start of radiotherapy | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and toxicity | Safety will be reported based on the occurrence of SAEs, SARs and SUSARs. Toxicity will be reported based on adverse events, as graded by CTCAE V5.0, and determined by routine clinical assessments at each centre. | 2 years after end of RT | 
| Treatment compliance | Treatment compliance will be measured by overall radiotherapy treatment time and delays, omissions and reductions to treatment doses (both DDRi and RT). | End of trial treatment (DDRi and RT) | 
| Best overall response | Best overall response will be measured as the best response (complete response, partial response or stable disease) recorded until disease progression, reported up to 2 years post-RT. This will be assessed using RECIST 1.1 | 2 years after end of RT | 
| Disease control | This will be assessed using the Green Criteria. Disease Control includes either the complete disappearance of all evidence of malignant disease or residual radiographic abnormalities assessed by chest CT scan at 3 and 6 months after completion of RT, which then remains stable for an additional 6 months or more and which then qualifies as controlled local disease. | 2 years after end of RT | 
| Progression-free survival | Participants who have not progressed at the time of analysis will be censored at the last date they were known to be alive and progression free | 2 years post-RT | 
| Overall survival | Participants who have not died at the time of analysis will be censored at the last date they were known to be alive | 2 years post-RT | 
| Changes in Health Related Quality of Life | Health Related Quality of Life will be determined using EORTC QLQ-C30, IL-73 and IL-74 | 2 years after end of RT | 
| Objective response rate | Objective response rate (ORR) is defined as the proportion of patients who have a partial or complete response to therapy. The proportion of patients with evaluable scans that achieve at least a partial response, as defined by RECIST v1.1(31), will be presented with 95% confidence intervals. | 2 years after end of RT | 
| Changes in tumour size during and following treatment with DDRi-RT compared to RT alone. |  | 2 years after end of RT |
