Trial Summary
What is the purpose of this trial?A Phase 1 Study to Investigate the Safety, Tolerability, Pharmacokinetics/Pharmacodynamics, and Antitumor Activity of NM1F as Monotherapy and in Combination with Pembrolizumab in Subjects with Locally Advanced/Metastatic Solid Tumors
Do I need to stop my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have had certain cancer treatments or immunosuppressive drugs recently, so it's best to discuss your specific medications with the trial team.
What data supports the effectiveness of the drug pembrolizumab for treating advanced breast cancer?
Pembrolizumab, also known as Keytruda, has been shown to improve survival rates and response rates in patients with advanced melanoma and non-small cell lung cancer, suggesting it may have potential benefits for other advanced cancers like breast cancer.
12345Is the combination of NM1F and Pembrolizumab safe for humans?
Pembrolizumab, also known as Keytruda, has been used in various cancer treatments and is generally considered safe, but it can cause side effects like fatigue, cough, nausea, and more serious immune-related issues like pneumonitis (lung inflammation) and thyroid problems. While specific safety data for NM1F is not provided, pembrolizumab's safety profile is well-documented in other conditions.
56789What makes the drug NM1F + Pembrolizumab unique for advanced breast cancer?
The combination of NM1F and Pembrolizumab is unique because it targets two different immune checkpoints, potentially enhancing the immune system's ability to fight advanced breast cancer. Pembrolizumab blocks the PD-1 protein, while NM1F targets PVRIG, a novel pathway, which may offer a new approach compared to existing treatments.

Long-Term Overall Survival From KEYNOTE-021 Cohort G: Pemetrexed and Carboplatin With or Without Pembrolizumab as First-Line Therapy for Advanced Nonsquamous NSCLC. [2021]In cohort G of KEYNOTE-021 (NCT02039674), first-line pembrolizumab plus pemetrexed-carboplatin significantly improved the objective response rate and progression-free survival versus chemotherapy alone with manageable toxicity in advanced nonsquamous NSCLC. We report the long-term outcomes from this study.
FDA Approval Summary: Pembrolizumab for Treatment of Metastatic Non-Small Cell Lung Cancer: First-Line Therapy and Beyond. [2022]On October 24, 2016, the U.S. Food and Drug Administration (FDA) approved pembrolizumab (Keytruda; Merck & Co., Inc., https://www.merck.com) for treatment of patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors express programmed death-ligand 1 (PD-L1) as determined by an FDA-approved test, as follows: (a) first-line treatment of patients with mNSCLC whose tumors have high PD-L1 expression (tumor proportion score [TPS] ≥50%), with no epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) genomic tumor aberrations, and (b) treatment of patients with mNSCLC whose tumors express PD-L1 (TPS ≥1%), with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving pembrolizumab.Approval was based on two randomized, open-label, active-controlled trials demonstrating statistically significant improvements in progression-free survival (PFS) and overall survival (OS) for patients randomized to pembrolizumab compared with chemotherapy. In KEYNOTE-024, patients with previously untreated mNSCLC who received pembrolizumab (200 mg intravenously [IV] every 3 weeks) had a statistically significant improvement in OS (hazard ratio [HR] 0.60; 95% confidence interval [CI]: 0.41-0.89; p = .005), and significant improvement in PFS (HR 0.50; 95% CI: 0.37-0.68; p < .001). In KEYNOTE-010, patients with disease progression on or after platinum-containing chemotherapy received pembrolizumab IV 2 mg/kg, 10 mg/kg, or docetaxel 75 mg/m2 every 3 weeks. The HR and p value for OS was 0.71 (95% CI: 0.58-0.88), p < .001 comparing pembrolizumab 2 mg/kg with chemotherapy and the HR and p value for OS was 0.61 (95% CI: 0.49-0.75), p < .001 comparing pembrolizumab 10 mg/kg with chemotherapy.
24-Month Overall Survival from KEYNOTE-021 Cohort G: Pemetrexed and Carboplatin with or without Pembrolizumab as First-Line Therapy for Advanced Nonsquamous Non-Small Cell Lung Cancer. [2022]Cohort G of KEYNOTE-021 (NCT02039674) evaluated the efficacy and safety of pembrolizumab plus pemetrexed-carboplatin (PC) versus PC alone as first-line therapy for advanced nonsquamous NSCLC. At the primary analysis (median follow-up time 10.6 months), pembrolizumab significantly improved objective response rate (ORR) and progression-free survival (PFS); the hazard ratio (HR) for overall survival (OS) was 0.90 (95% confidence interval [CI]: 0.42‒1.91). Herein, we present an updated analysis.
Pembrolizumab: A Review in Advanced Melanoma. [2022]Pembrolizumab (Keytruda(®)) is a humanized monoclonal antibody against programmed death receptor-1 (PD-1), a key immunoinhibitory checkpoint protein implicated in down-regulating anti-tumour immune responses. This intravenous drug is indicated for the treatment of advanced (unresectable or metastatic) melanoma, on the basis of its clinical benefit in this setting in the phase I KEYNOTE 001 trial (expansion cohorts) and the phase II and III trials, KEYNOTE 002 and 006. These studies were conducted in ipilimumab-naïve and/or ipilimumab-experienced patients and assessed varying pembrolizumab regimens administered every 2 or 3 weeks, all of which helped to determine the recommended dosage of 2 mg/kg every 3 weeks. In the trials with active comparator arms, pembrolizumab regimens significantly improved progression-free survival (PFS), overall survival (OS) and overall response rates (ORR) relative to ipilimumab in ipilimumab-naïve patients (KEYNOTE 006), and significantly improved PFS and ORR, but not OS (although OS data are immature), relative to chemotherapy in ipilimumab-refractory patients, who had also received BRAF/MEK inhibitor therapy if BRAF-mutation positive (KEYNOTE 002). Pembrolizumab has an acceptable tolerability profile, with immune-related adverse events that are generally manageable/reversible. Thus, pembrolizumab is a valuable treatment option for patients with advanced melanoma, including those who have progressed on ipilimumab and BRAF/MEK inhibitors.
FDA Approval Summary: Accelerated Approval of Pembrolizumab for Second-Line Treatment of Metastatic Melanoma. [2021]On September 4, 2014, the FDA approved pembrolizumab (KEYTRUDA; Merck Sharp & Dohme Corp.) with a recommended dose of 2 mg/kg every 3 weeks by intravenous infusion for the treatment of patients with unresectable or metastatic melanoma who have progressed following treatment with ipilimumab and, if BRAF V600 mutation positive, a BRAF inhibitor. Approval was based on demonstration of objective tumor responses with prolonged response durations in 89 patients enrolled in a randomized, multicenter, open-label, dose-finding, and activity-estimating phase 1 trial. The overall response rate (ORR) by blinded independent central review per RECIST v1.1 was 24% (95% confidence interval, 15-34); with 6 months of follow-up, 86% of responses were ongoing. The most common (≥20%) adverse reactions were fatigue, cough, nausea, pruritus, rash, decreased appetite, constipation, arthralgia, and diarrhea. Immune-mediated adverse reactions included pneumonitis, colitis, hepatitis, hypophysitis, and thyroid disorders. The benefits of the observed ORR with prolonged duration of responses outweighed the risks of immune-mediated adverse reactions in this life-threatening disease and represented an improvement over available therapy. Important regulatory issues in this application were role of durability of response in the evaluation of ORR for accelerated approval, reliance on data from a first-in-human trial, and strategies for dose selection.

Recurrent and atypical immune checkpoint inhibitor-induced pneumonitis. [2023]Pembrolizumab (Keytruda) is a monoclonal antibody against the programmed cell death-1 (PD-1) receptor on lymphocytes, which is one of the immune checkpoint inhibitors (ICIs) approved for multiple solid and hematologic malignancies. Although ICIs have proven to be more effective and less toxic compared to chemotherapy, there are reports of adverse side effects with ICIs. For example, pneumonitis is a potentially lethal side effect occurring in 1%-5% of patients who received ICIs in clinical trials, and there are case reports with clinical and radiological features of checkpoint inhibitor-pneumonitis (CIP).
FDA Approval Summary: Pembrolizumab for the Treatment of Patients with Unresectable or Metastatic Melanoma. [2022]On December 18, 2015, the FDA granted regular approval to pembrolizumab (KEYTRUDA; Merck Sharp & Dohme Corp.) for treatment of patients with unresectable or metastatic melanoma based on results of two randomized, open-label, active-controlled clinical trials. In trial PN006, 834 patients with ipilimumab-naïve metastatic melanoma were randomized (1:1:1) to pembrolizumab 10 mg/kg i.v. every 2 or 3 weeks until disease progression or ipilimumab 3 mg/kg every 3 weeks for up to four doses. In trial PN002, 540 patients with ipilimumab-refractory metastatic melanoma were randomized (1:1:1) to pembrolizumab 2 or 10 mg/kg i.v. every 3 weeks or to investigator's choice of chemotherapy. In trial PN006, patients randomized to pembrolizumab demonstrated a statistically significant improvement in overall survival compared with ipilimumab [every-2-week arm: hazard ratio (HR) = 0.63; 95% confidence interval (CI), 0.47-0.83; P < 0.001; every-3-week arm: HR = 0.69; 95% CI, 0.52-0.90; P = 0.004]. In both trials, patients receiving pembrolizumab demonstrated statistically significant improvements in progression-free survival. The most common (≥2%) immune-mediated adverse reactions in a pooled safety analysis were hypothyroidism, pneumonitis, and hyperthyroidism. Key considerations for approval were determination of pembrolizumab dose and interpretation of tumor response-based endpoints using RECIST or immune-related RECIST.

Neoadjuvant anti-programmed death-1 immunotherapy by pembrolizumab in resectable non-small cell lung cancer: First clinical experience. [2022]A phase II trial investigating the therapeutic effect of neoadjuvant programmed cell death 1 (PD-1) inhibitor pembrolizumab (MK-3475, KEYTRUDA®) administered prior to surgery for the treatment of non-small cell lung cancer (NSCLC) has been conducted (NCT03197467). We report the first clinical results of a planned interim safety analysis after 15 patients were enrolled.
Programmed Cell Death-1 Inhibitor-Induced Type 1 Diabetes Mellitus. [2022]Pembrolizumab (Keytruda; Merck Sharp & Dohme) is a humanized IgG4 monoclonal antibody used in cancer immunotherapy. It targets the programmed cell death-1 (PD-1) receptor, which is important in maintaining self-tolerance. However, immune checkpoint blockade is associated with a risk for immune-related adverse events (irAEs) potentially affecting the endocrine organs. Type 1 diabetes mellitus is a rare irAE of PD-1 inhibitors, occurring in 0.2% of cases.
Pembrolizumab: first global approval. [2021]Pembrolizumab [Keytruda(®) (US)], a humanized monoclonal antibody against the programmed death receptor-1 (PD-1) protein, has been developed by Merck & Co for the treatment of cancer. Pembrolizumab has received its first global approval for the treatment of advanced, unresectable or metastatic malignant melanoma in the US, for use in patients with disease progression after prior treatment with ipilimumab and, for BRAF V600 mutation-positive patients, a BRAF inhibitor. It is the first anti-PD-1 therapy to receive regulatory approval in the US, and is currently under regulatory review in the EU. This article summarizes the milestones in the development of pembrolizumab leading to this first approval for the treatment of malignant melanoma.
Efficacy and safety of pembrolizumab for treating advanced non-small-cell lung cancer: a meta-analysis of phase II and III randomized controlled trials. [2022]We conducted a meta-analysis to systematically review the efficacy and safety of pembrolizumab for advanced NSCLC. Databases were searched for randomized controlled trials (RCTs) treated with pembrolizumab till July 2021. Seven RCTs and 3988 patients were included. Our analysis suggests that pembrolizumab was more effective at improving PFS (HR, 0.59; 95% CI: 0.43-0.79; p = 0.0005), OS (HR, 0.65; 95% CI: 0.55-0.76; p ＜ 0.00001) and ORR (RR, 1.85; 95% CI: 1.64-2.09; p ＜ 0.00001) than chemotherapy. Patients with higher PD-L1 expression level were tend to have a better PFS, OS and ORR. Combination therapy of pembrolizumab was superior to pembrolizumab monotherapy in enhancing PFS. Pembrolizumab did not increase the frequency of commonly reported adverse events, but the immune-related adverse events (irAEs) occurred more frequently in the pembrolizumab group than those in the chemotherapy group. The pembrolizumab significantly improved the PFS, OS and ORR, simultaneously increasing the irAEs.
Biophysical and Immunological Characterization and In Vivo Pharmacokinetics and Toxicology in Nonhuman Primates of the Anti-PD-1 Antibody Pembrolizumab. [2021]The programmed cell death 1 (PD-1) pathway represents a major immune checkpoint, which may be engaged by cells in the tumor microenvironment to overcome active T-cell immune surveillance. Pembrolizumab (Keytruda®, MK-3475) is a potent and highly selective humanized mAb of the IgG4/kappa isotype designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2. This blockade enhances the functional activity of T cells to facilitate tumor regression and ultimately immune rejection. Pembrolizumab binds to human and cynomolgus monkey PD-1 with picomolar affinity and blocks the binding of human and cynomolgus monkey PD-1 to PD-L1 and PD-L2 with comparable potency. Pembrolizumab binds both the C'D and FG loops of PD-1. Pembrolizumab overcomes human and cynomolgus monkey PD-L1-mediated immune suppression in T-cell cultures by enhancing IL2 production following staphylococcal enterotoxin B stimulation of healthy donor and cancer patient cells, and IFNγ production in human primary tumor histoculture. Ex vivo and in vitro studies with human and primate T cells show that pembrolizumab enhances antigen-specific T-cell IFNγ and IL2 production. Pembrolizumab does not mediate FcR or complement-driven effector function against PD-1-expressing cells. Pembrolizumab displays dose-dependent clearance and half-life in cynomolgus monkey pharmacokinetic and toxicokinetic studies typical for human IgG4 antibodies. In nonhuman primate toxicology studies, no findings of toxicologic significance were observed. The preclinical data for pembrolizumab are consistent with the clinical anticancer activity and safety that has been demonstrated in human clinical trials.
