A Randomized Phase II Study of Paclitaxel and Ramucirumab +/- Zanidatamab in HER2 Positive Advanced Gastroesophageal Adenocarcinoma

Participants with advanced stomach, gatroesophageal junction or esophageal cancer that is not treatable by surgical removal and which has high amounts of human epidermal growth factor receptor Type 2 (aka HER2) on the surface of their tumour cells, receive the anti-HER2 drug trastuzumab added to chemotherapy as standard of care, with the benefit that the addition of trastuzumab extends their survival. Investigation of other drugs that target HER2 and other cancer surface proteins simultaneously, or that link HER2 with another anti-cancer drug, have not shown benefit for these participants to-date. When these participants experience further growth of their cancer due to resistance, their next option for treatment is a combination of a toxic chemotherapy and a drug which binds to another cancer surface protein known as the vascular endothelial growth factor receptor type 2 (VEGFR2). Zanidatamab is a new type of antibody/drug that targets HER2, but offers the possible benefit over trastuzumab that it can not only bind slightly different versions of HER2, but it can also bind two HER2 receptors simultaneously. This means that zanidatamab may do a better, more efficient job of blocking HER2 receptors and may therefore have better effect in slowing tumour growth, or even causing tumour cell death. Early trials of zanidatamab in patients with stomach and esophageal cancers expressing HER2 have yielded very promising results both in terms of the effect on their cancers as well as the tolerability of zanidatamab. The current phase II study is seeking to determine whether there is sufficient early evidence that adding zanidatamab to the standard of care therapy for those participant who have become resistant to trastuzumab can better slow the growth of their tumours in order to proceed with a definitive, confirmatory phase III study which would be expected to lead to the approval of zanidatamab as standard of care treatment of these participants.


Complexity Level: 2

Eligibility: Patients must: Have histologically or pathologically confirmed gastroesophageal adenocarcinoma with HER2+ overexpression as confirmed by central testing using FDA-approved HER2 assay that is unresectable or metastatic. Have received and failed at lease one prior trastuzumab-containing regimen (combination with platinum chemotherapy) for treatment of metastatic disease. Failure is defined as demonstrated objective disease progression (radiologic). Have presence of measurable or evaluable disease as defined by Response Evaluation Criteria in Solid Tumours (RECIST 1.1). Have imaging investigations including CT/MRI of chest/abdomen/pelvis or other scans as necessary to document all sites of disease done within 28 days prior to randomization. ECOG performance status of 0 or 1. Have a life expectancy of > 12 weeks at the time of study entry. Adequate cardiac function by ECHO or MUGA defined as EF > 50% Have adequate normal organ and marrow function

Objectives: Primary objective: Progression free survival Secondary objectives: Overall Survival, Objective Response Rate, Toxicity and Safety of Combination Therapy, Quality of Life, Identification and assessment of putative biomarkers of potential benefit in archival tumour specimens and baseline and on-treatment blood, serum and plasma samples, Other exploratory correlative analyses TBD

Perioperative versus Adjuvant Chemotherapy for Resectable Pancreatic Cancer

The purpose of this study is to compare the usual treatment approach (surgery followed by chemotherapy) to using chemotherapy followed by surgery and then more chemotherapy. The addition of chemotherapy before surgery to the usual treatment approach could extend the life of patients, but it could also cause side effects. This study will help doctors find out if this different approach is better, the same, or worse than the usual approach. To decide if it is better, the doctors will be looking to see if the study approach increases the life of patients compared to the usual approach. This chemotherapy drug regimen, FOLFIRINOX, is already commonly used in pancreatic cancer. However, most of the time it is not used until after surgery.


Complexity Level: 2

Eligibility: Histologic or cytologic proof of pancreatic adenocarcinoma or adenosquamous carcinoma, TNM Stage: Tx-4, N0-1, M0 Local radiographic reading consistent with resectable disease Confirmation of resectable disease by real-time central imaging review by the Alliance Imaging Core Lab at IROC Ohio Determined to be appropriate candidate for curative-intent pancreatectomy No prior radiation therapy, chemotherapy, targeted therapy, investigational therapy or surgery for pancreatic cancer Not pregnant and not nursing Age > or = to 18 years ECOG Performance Status 0-1 Total Neuropathy Score < 2 No known Gilbert's Syndrome or known homozygosity for UGATA1A1*28 polymorphism No comorbid conditions that would prohibit curative-intent pancreatectomy Chronic concomitant treatment with strong inhibitors and/or inducers of CYP3A4 is not allowed Measurable disease and/or non-measurable disease

Objectives: The primary objective of this study is to evaluate and compare overall survival (OS) in patients with resectable pancreatic adenocarcinoma (PDAC) treated with perioperative mFOLFIRINOX and surgery versus up-front surgery followed by adjuvant mFOLFIRINOX.

Phase II/III Study of Circulating tumOr DNA as a Predictive BiomarRker in Adjuvant Chemotherapy in Patients with Stage IIA Colon Cancer (COBRA)


Complexity Level: 3

Eligibility: Patients must 1) have histologically/pathologically confirmed stage 2A adenocarcinoma of colon with at least 12 LNs examined at resection 2) be appropriate for active surveillance 3) distal extent of tumor must be 12cm from the anal verge 4) complete gross tumor resection (curative resection) within 14-60 d of randomization 5) adequate tumor for testing 6) adequate hematologic-hepatic-renal function within 28 d before randomization 7) ECOG 0 or 1 8) only adenocarcinoma colon cancer histology 9) no metastatic disease 10) no tumor-related bowel perforation, history of prior invasive colon malignancy or organ transplantation 11) no prior systemic chemo, targeted therapy, IO, or RT for CRC 12) no other invasive malignancy & no antineoplastic therapy within 5 yrs before randomization 13) no uncontrolled cardiac disease 14) no sensory or motor neuropathy gr 2, active uncontrolled seizure disorder, active or chronic infection requiring systemic therapy, known homozygous DPD deficiency

Objectives: PRIMARY OBJECTIVE (PH 2) - To compare the rate of ctDNA clearance in "ctDNA detected" patients treated with or without adjuvant chemotherapy following resection of stage IIA colon cancer PRIMARY OBJECTIVE (PH 3) - To compare RFS in "ctDNA detected" patients treated with or without adjuvant chemotherapy following resection of stage IIA colon cancer SECONDARY OBJECTIVES - in patients with stage IIA colon cancer: - To describe the prevalence of detectable ctDNA following surgical resection - To estimate time-to-event outcomes (OS, RFS, TTR) by ctDNA marker status & treatment - To estimate the rate of compliance with adjuvant chemotherapy &/or active surveillance EXPLORATORY OBJECTIVES: - To describe the association of quantitative ctDNA levels with time to event outcomes (RFS, OS, & TTR) - To characterize genomic profiles associated with recurrence using a ctDNA assay - To model the cost effectiveness of the use of ctDNA vs SOC in this setting

Complexity Level: 2

Eligibility: Patients with low or intermediate grade neuroendocrine carcinoma arising from the foregut, midgut, hindgut or other non-pancreatic site which is locally unresectable or metastatic.
