Chemoradiation and Consolidation Chemotherapy With or Without Oxaliplatin for Distal Rectal Cancer and Watch and Wait
Patients and Methods Patients with distal rectal cancer will be eligible for the study after initial clinical, endoscopic and radiological assessment. At this point, patients will be offered to participate in the study and after informed consent, randomized to control or experimental arms as follows. Endpoints Primary endpoint: Decision to Watch and Wait due to clinical complete response achieved at 18 weeks from last date of radiation using clinical (DRE), endoscopic and radiological criteria (mrTRG grade) or near-complete clinical response (no progressive disease clinically, endoscopically or radiologically) Definition of clinical complete response (cCR) available below and at the discretion of the attending surgeon. Definition of radiological complete response as described below (centralized). Patients will be counted as event if at 18 weeks the decision is to interrupt Watch and Wait and proceed to surgery (any kind) because of overt incomplete clinical response. In order to standardize assessment of response and reduce inter-observer variability, the decision to continue on Watch and Wait (or not) will be at the discretion of the central committee during central revision of studies. Secondary endpoints: - Surgery-free survival at 3 years - TME-free survival at 3 years - Distant metastases free survival at 3 years - Local regrowth-free survival at 3 years - Colostomy-free survival at 3 years Definitions Definition of cCR: - Endoscopic: white scar, teleangiectasia, absence of ulceration and/or mass 6 - Clinical: no irregularity, firm area with minor induration6 - Radiological: mrTRG1: fibrosis with low signal intensity seen on T2 weighted images replacing the primary tumor; no restricted diffusion on diffusion weighted images; no nodes with border irregularity or mixed signal intensity; no extramural vascular invasion23-26 Definition of near-complete response: - Endoscopic: residual tumor size ≤2cm (or reduction of ≥70% original tumor volume/size) 4,27,28 - Clinical: only superficial ulceration or minor (questionable) irregularities of the mucosal/rectal wall - Radiological: mrTRG2 predominant fibrosis with low signal with foci of intermediate tumor signal intensity seen on T2 weighted images with or without restricted diffusion; mrTRG1: fibrosis with low signal intensity seen on T2 weighted images replacing the primary tumor with restricted diffusion; no nodes with border irregularity or mixed signal intensity; no extramural vascular invasion 27 Central Committee The central committee is multidisciplinary group of surgeons, medical oncologists and radiologists previously appointed at the beginning of the recruitment of patients and with previous experience with organ preservation.2, 21 This group of specialist will be responsible to assess the baseline staging and define if the patients fulfill all the inclusion/exclusion criteria prior to randomization. The committee will also be responsible to evaluate the endoscopic and radiological tumor re-assessment studies at 12 and 18 weeks from radiation completion. The definition to continue on the Watch and Wait pathway or not will be at the discretion of this committee. Technical aspects of assessment tests: Suggested MR protocol: 1.5T - FRFSE; TR/TE: 3300/120 (ms); slice thickness/gap: 3.0/0; Matrix: 256 x 256; NSA 8) 3.0T - FRFSE; TR/TE: 8000/150 (ms); slice thickness/gap: 3.0/0; Matrix: 288 x 288; NSA 5) DWI - inclusion of a high b-value of at least 800 Suggested Endoscopic assessment: Endoscopic assessment using a flexible scope (gastroscope preferred for retroflexion); direct endoscopic and retroflexion view of the primary tumor/scar; endoscopic biopsies at discretion of participating center. Radiotherapy Preoperative radiotherapy will be delivered on a linear accelerator in prone or supine position, preferably with full bladder. The use of a belly board is allowed. Isocentric 3 or 4 fields, as well as an IMRT technique is allowed, as long as all beams are treated on a daily basis. The dose distribution and calculation should be performed on CT or MRI and specified according to the ICRU 50 guidelines. Dose specification: All patients will receive 25 daily fractions of 1.8 Gy up to a total dose of 45 Gy to the pelvic field including the tumor bed with a margin and the regional lymph nodes. A field reduction after 45 Gy is recommended up to 54 Gy. The last 5 fractions will then be given to the tumor bed with a margin. Target volume: Pelvic CTV - The primary tumor - Mesorectum: Distally, only lymph nodes or tumor deposits up to 4 cm are included. For tumors in lower rectum this means that the entire mesorectum down to the pelvic floor is included. - Presacral nodes and nodes along the rectal superior artery: Since local recurrences are very unusual above S1 - S2, lymph nodes above this level should not be included unless there are signs of radiologically positive lymph nodes presacrally. If this is the case, the cranial limit of CTV should be at least 1 cm above the most cranial radiologically positive lymph node. - Lateral lymph node stations: Until they reach the level of the obturator canal Internal iliac artery up to the bifurcation from the external iliac artery. The cranial border for the CTV is in most cases just below the bifurcation of the internal and external iliac arteries. In most patients this is at the level of S1 - S2. - Ischio-rectal fossa and the anal canal: Included in pelvic CTV only if the tumor grows into the levators or down into the anal canal. - Lymph nodes along the external iliac artery: Included if the tumor grows into anterior organs like the prostate, urinary bladder, cervix, vagina or uterus to such an extent that the external nodes are at risk for metastases. Boost GTV: GTV is the visible primary tumor and radiologically positive lymph nodes. CTV boost: GTV boost plus a margin of 2 cm within the same anatomical compartment as the tumour is in, for the dose of 45 Gy, also around radiologically engaged lymph nodes. PTV: The above description relates to the CTV. A PTV should normally be defined and includes CTV and internal target volume (ITV) and a margin necessary for the setup. These margins are depending upon several factors that are related to the equipment at each radiotherapy center. Chemotherapy Protocols Concomitant chemotherapy: Concomitant capecitabine: 825mg/m2 bid on the radiotherapy days only Consolidation chemotherapy: 1. Consolidation capecitabine (alone): 1000mg/m2 bid, for 14 days, in a 3 week cycle, for 4 cycles 2. Consolidation options with oxaliplatin: 2.1. mFOLFOX6: Oxaliplatin 85mg/m2 plus Leucovorin 400mg/m2 on a concomitant 2 hours infusion. 5FU 400mg/m2 on a bolus infusion, followed by 5FU 2400mg/m2 in 46 hours infusion, every 2 weeks, for 6 cycles 2.2. CAPOX: Oxaliplatin 130mg/m2 on a 2 hours infusion. Capecitabine 1000mg/m2 bid daily, for 14 days, starting on the evening of the oxaliplatin infusion. Repeat every 3 weeks, for 4 cycles Assessment of Response Assessment of response will be performed at 12 weeks (and 18 weeks from last date of radiation therapy if cCR or near-complete response is detected at 12 weeks). All patients will undergo endoscopic reassessment, DRE and high-resolution MR. Endoscopic biopsies will be at the discretion of the attending surgeon/endoscopist. Patients with complete or near-complete clinical response at 12 weeks will be recommended reassessment at 18 weeks from RT. Patients with clinically overt incomplete clinical response at 12 or 18 weeks will be referred to immediate radical surgery. Randomization Individuals will be randomized and allocated at a 1:1 ratio to the two groups (control and experimental) using a permuted block design with a random block size of 4, 6, and 8. (1-3) A randomization list will be generated electronically using appropriate software immediately after being considered eligible. Protocol Blinding Patients and attending physicians will not be blinded to the treatment arm randomized for each patient. However, as a strategy to reduce investigator's expectations and reduce inherent bias, the central committee will be blinded to the treatment arm. It is expected that blinding the central committee, who will be responsible for assessing the primary endpoint, any bias related to the investigator's expectation about the treatment arm and the chances of Watch and Wait will be nulled. Sample size calculation The primary endpoint (decision to WW due to cCR/near CR) was observed in 55% and 85% at 12 weeks (in contrast to the 18 weeks used in the present trial) among patients with early cT3 and cT2 rectal cancer respectively.29 In this study, there was a distribution of 66% of cT3 and 33% cT2. Therefore, response rates appear to be highly dependent on exact T-stage distribution. Considering the expected inclusion of more advanced disease (late mrT3 or even mrT4 rectal cancers) the investigators expect 40% cCR/near-CR in the control arm. A similar difference 60% versus 40% was achieved in the preliminary report of the outcomes of the OPRA trial. This difference in TME-free survival at 3 years was statistically significant favoring patients undergoing nCRT with cCT in comparison to nCRT preceded by induction chemotherapy (both regimens incorporating oxaliplatin). In this setting, if experimental results in ≥60% cCR/near-CR, the study will be considered POSITIVE. The incorporation of oxaliplatin to a consolidation CRT regimen that results in ≥20% increase in cCR/near-CR exceeds the potential disadvantages of treatment-related toxicity. The investigators will assume that the primary outcome will occur in 40% of individuals in control group and 60% in the experimental group, which corresponds to an absolute difference in proportions of 20%. It is estimated that a sample of 194 (97 per group) provides 80% statistical power to detect this difference at a significance level of 5% using the Chi-square test and assuming a two-sided significance hypothesis and considering a 1:1 allocation. The estimated dropout rate is 10% in each group, so it is expected to include 216 individuals (108 per group). The sample size calculation was performed using SAS 9.4 (PROC POWER procedure). Time-table Patient accrual: 2 years and 6 months Patient/institution/year: 5-6 (20 institutions: 100-120/year - 2 years n=200-240) Interim analysis: If the arm of two drugs during consolidation shows ≥25% response rate after 72 patients, study will be interrupted (efficacy). If the arm of two drugs shows less than 5% response rate after 72 patients, the study will be interrupted.

A Study to Check the Safety of Dexlansoprazole and Learn if it Can Treat Symptomatic Nonerosive Gastroesophageal Reflux Disease in Children 2 to 11 Years Old
The drug being tested in this study is called dexlansoprazole. Dexlansoprazole is being tested to treat children aged 2 to 11 years who have nonerosive GERD. This study will look at the effectiveness and side effects of three different doses of dexlansoprazole in children with GERD. The study will enroll approximately 70 patients. Participants weighing ≤30 kilograms (kg) will be randomly assigned (by chance, like flipping a coin) to receive dexlansoprazole 15 or 30 milligrams (mg), and participants who weigh >30 kg will be randomized to receive dexlansoprazole 30 or 60 mg. All participants will be asked to take one capsule at the same time each day throughout the study. Parents/caregivers for participants ages 2 to 8 and participants ages 9 to 11 will be asked to record any time they have heartburn symptoms in an electronic diary. This multi-center trial will be conducted worldwide. The overall time to participate in this study is up to 16 weeks, which includes up to 4 weeks to screen for the study. Participants will make multiple visits to the clinic, plus a final phone call 5 to 10 days after last dose of study drug for a follow-up assessment.
