Trastuzumab Plus Pertuzumab Versus Cetuximab Plus Irinotecan in Patients With Wild-Type, HER2-Positive, Metastatic Colorectal Cancer (S1613): A Randomized Phase II Trial.

Purpose: overexpression/amplification in wild-type (WT) metastatic colorectal cancer (mCRC; human epidermal growth factor receptor 2 [HER2]-positive mCRC) appears to be associated with limited benefit from anti-EGFR antibodies and promising responses to dual-HER2 inhibition; however, comparative efficacy has not been investigated. We conducted a randomized phase II trial to evaluate efficacy and safety of dual-HER2 inhibition against standard-of-care anti-EGFR antibody-based therapy as second/third-line treatment in HER2-positive mCRC.

Methods: Patients with -WT mCRC after central confirmation of HER2 positivity (immunohistochemistry 3+ or 2+ and in situ hybridization amplified [HER2/CEP17 ratio >2.

A Phase 1b study of the OxPhos inhibitor ME-344 with bevacizumab in refractory metastatic colorectal cancer.

Antiangiogenic drugs may cause vascular normalization and correct hypoxia in tumors, shifting cells to mitochondrial respiration as the primary source of energy. In turn, the addition of an inhibitor of mitochondrial respiration to antiangiogenic therapy holds potential to induce synthetic lethality. This study evaluated the mitochondrial inhibitor ME-344 in combination with bevacizumab in patients with refractory metastatic colorectal cancer (mCRC).

SWOG S1815: A Phase III Randomized Trial of Gemcitabine, Cisplatin, and Nab-Paclitaxel Versus Gemcitabine and Cisplatin in Newly Diagnosed, Advanced Biliary Tract Cancers.

Purpose: SWOG S1815 was a randomized, open label phase III trial, evaluating gemcitabine, nab-paclitaxel, and cisplatin (GAP) versus gemcitabine and cisplatin (GC) in patients with newly diagnosed advanced biliary tract cancers (BTCs).

Methods: Patients with newly diagnosed locally advanced unresectable or metastatic BTC, including intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC) and gallbladder carcinoma (GBC), were randomly assigned 2:1 to either GAP (gemcitabine 800 mg/m, cisplatin 25 mg/m, and nab-paclitaxel 100 mg/m intravenously once per day on days 1 and 8 of a 21-day cycle) or GC (gemcitabine 1,000 mg/m and cisplatin 25 mg/m intravenously once per day on days 1 and 8 of a 21-day cycle).

Results: Among 452 randomly assigned participants, 441 were eligible and analyzable, 67% with ICC, 16% with GBC, and 17% with ECC.

Evolution of Rapid Clonal Dynamics and Non-Cross-Resistance in Response to Alternating Targeted Therapy and Chemotherapy in BRAF-V600E-Mutant Colon Cancer.

Purpose: Combined BRAF, MEK, and EGFR inhibition can induce clinical responses in BRAF-V600E-mutant colon cancer, but rapid resistance often occurs.

Methods: We use serial monitoring of circulating tumor DNA cell-free plasma DNA (cfDNA) in a patient case study in addition to organoids derived from mouse models of BRAF-V600E-mutant intestinal cancer, which emulated the patient's mutational profile to assess drug treatment efficacy.

Results: We demonstrate dynamic evolution of resistance to combined EGFR/BRAF/MEK inhibition in a pediatric patient with metastatic BRAF-V600E-mutant, mismatch repair-stable colon cancer.

Phase I-II study of OBI-888, a humanized monoclonal IgG1 antibody against the tumor-associated carbohydrate antigen Globo H, in patients with advanced solid tumors.

Purpose: OBI-888 is a humanized, monoclonal IgG1 antibody specific to the tumor-associated carbohydrate antigen Globo H. We conducted a phase I-II study of OBI-888 in patients with advanced cancer.

Methods: Patients were treated with OBI-888 5, 10, or 20 mg/kg IV weekly in Part A ("3 + 3" design) and 20 mg/kg IV weekly in Part B (Simon's 2-stage design) (1 cycle = 28 days).

A phase II study of FOLFOX combined with nab-paclitaxel in the treatment of metastatic or advanced unresectable gastric, gastroesophageal junction adenocarcinoma: a Big Ten Cancer Research Consortium trial.

Background: Doublet platinum or taxane-based therapies are the current standard backbone of treatment for advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Previously used anthracycline-based triplet regimens are no longer used routinely due to toxicity and lack of superior efficacy. We hypothesized that the addition of nab-paclitaxel to FOLFOX (FOLFOX-A) would induce higher efficacy and better tolerability.

TAS-102, Irinotecan, and bevacizumab in pre-treated metastatic colorectal cancer (TABAsCO), a phase II clinical trial.

Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumour efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study.

A single arm phase 2 clinical trial of YIV-906 with neoadjuvant concurrent chemo-radiation therapy in patients with locally advanced rectal cancer.

Background: Pre-operative chemoradiation for rectal cancer is often associated with severe gastrointestinal (GI) toxicity which can interrupt, delay, and/or lead to termination of treatment. In this study, we evaluated whether the addition of YIV-906, a novel herbal medicine proven to reduce GI toxicity associated with chemotherapy could also reduce GI side effects during standard pre-operative capecitabine and pelvic radiation therapy (RT) in the neoadjuvant setting for the treatment of locally advanced rectal cancer.

Methods: This single arm clinical study enrolled 24 patients between Dec 23, 2014-Sep 17, 2018 at Smilow Cancer Hospital, a comprehensive cancer center at Yale New Haven Hospital.

COMPANION-002 A clinical trial of investigational drug CTX-009 plus paclitaxel vs paclitaxel in second line advanced BTC.

Treatment options for patients with biliary tract cancer are limited, and the prognosis is poor. CTX-009, a novel bispecific antibody targeting both DLL4 and VEGF-A, has demonstrated antitumor activity in patients with advanced cancers as both a monotherapy and in combination with chemotherapy. In a phase II study of patients with advanced biliary tract cancer who had received one or two prior therapies, CTX-009 with paclitaxel demonstrated a 37.

Combining antivascular endothelial growth factor and anti-epidermal growth factor receptor antibodies: randomized phase II study of irinotecan and cetuximab with/without ramucirumab in second-line colorectal cancer (ECOG-ACRIN E7208).

Background: Early studies showed promise of combined anti-epidermal growth factor receptor (EGFR) plus anti-vascular endothelial growth factor (VEGF) antibodies for advanced colorectal cancer (CRC), yet this was later rejected as toxic and ineffective in studies not selected for RAS status. We studied advanced KRAS wild-type CRC, as second-line treatment, using irinotecan-cetuximab with or without the anti-VEGF receptor antibody ramucirumab.

Methods: Patients with 1 prior regimen including fluoropyrimidine, oxaliplatin, and bevacizumab, with KRAS wild-type tumors were stratified by Eastern Cooperative Oncology Group Performance Score, time since last chemotherapy, and progression on oxaliplatin to irinotecan-cetuximab (IC) (180 mg/m2 and 500 mg/m2 every 2 weeks) vs modified ICR (irinotecan-cetuximab with ramucirumab 150 mg/m2 and 400 mg/m2 plus 6 mg/kg, respectively).

Combination of Immunotherapy and Radiation Therapy in Gastrointestinal Cancers: An Appraisal of the Current Literature and Ongoing Research.

Oncological outcomes are improving in gastrointestinal cancer with advancements in systemic therapies, and there is notable potential in combining immunotherapy and radiation therapy (RT) to allow for further improvements. Various preclinical and early phase II studies have shown promising synergy with immunotherapy and RT in gastrointestinal cancer. A few recent phase III studies have shown improved survival with the addition of immunotherapy to standard treatment for gastrointestinal cancer.

Circulating Tumor DNA as a Predictive Biomarker for Clinical Outcomes With Margetuximab and Pembrolizumab in Pretreated HER2-Positive Gastric/ Gastroesophageal Adenocarcinoma.

Purpose: To assess the ability of circulating tumor DNA (ctDNA)-based testing to identify patients with HER2 (encoded by ERBB2)-positive gastric/gastroesophageal adenocarcinoma (GEA) who progressed on or after trastuzumab-containing treatments were treated with combination therapy of anti-HER2 and anti-PD-1 agents.

Methods: ctDNA analysis was performed retrospectively using plasma samples collected at study entry from 86 patients participating in the phase 1/2 CP-MGAH22-05 study (NCT02689284).

Results: Objective response rate (ORR) was significantly higher in evaluable ERBB2 amplification-positive vs - negative patients based on ctDNA analysis at study entry (37% vs 6%, respectively; P = .

Trifluridine/tipiracil with or without bevacizumab in metastatic colorectal cancer: results of a systematic review and meta-analysis.

Background: Trifluridine/tipiracil plus bevacizumab (FTD/TPI + BEV) has shown efficacy and tolerability in refractory metastatic colorectal cancer (mCRC). Because randomized controlled trial (RCT) data comparing FTD/TPI + BEV with FTD/TPI are lacking, this meta-analysis evaluated outcomes with both regimens.

Data Sources And Methods: Electronic databases, congress proceedings (past 3 years), trial registries, systematic review bibliographies, gray literature, and guidelines through June 2021 were searched for RCTs, non-RCTs, and prospective observational studies involving >20 previously treated patients with mCRC receiving FTD/TPI + BEV or FTD/TPI.

Dietary fat in relation to all-cause mortality and cancer progression and death among people with metastatic colorectal cancer: Data from CALGB 80405 (Alliance)/SWOG 80405.

Data on diet and survival among people with metastatic colorectal cancer are limited. We examined dietary fat in relation to all-cause mortality and cancer progression or death among 1149 people in the Cancer and Leukemia Group B (Alliance)/Southwest Oncology Group (SWOG) 80405 trial who completed a food frequency questionnaire at initiation of treatment for advanced or metastatic colorectal cancer. We examined saturated, monounsaturated, total and specific types (n-3, long-chain n-3 and n-6) of polyunsaturated fat, animal and vegetable fats.

A Pilot Study of Omalizumab to Treat Oxaliplatin-Induced Hypersensitivity Reaction.

Background: Oxaliplatin hypersensitivity reactions (HSRs) are immunoglobulin E (IgE)-mediated and prevent maximum benefit from this drug. This study was designed to determine whether oxaliplatin HSRs could be prevented or reduced with omalizumab (Xolair), an anti-IgE antibody.

Patients/methods: This was a single-arm prospective pilot study.

Development of an aerosol intervention for COVID-19 disease: Tolerability of soluble ACE2 (APN01) administered via nebulizer.

As ACE2 is the critical SARS-CoV-2 receptor, we hypothesized that aerosol administration of clinical grade soluble human recombinant ACE2 (APN01) will neutralize SARS-CoV-2 in the airways, limit spread of infection in the lung, and mitigate lung damage caused by deregulated signaling in the renin-angiotensin (RAS) and Kinin pathways. Here, after demonstrating in vitro neutralization of SARS-CoV-2 by APN01, and after obtaining preliminary evidence of its tolerability and preventive efficacy in a mouse model, we pursued development of an aerosol formulation. As a prerequisite to a clinical trial, we evaluated both virus binding activity and enzymatic activity for cleavage of Ang II following aerosolization.
