How long do you stay on immunotherapy for melanoma?
People with melanoma are recommended to take an immune checkpoint inhibitor for 12 months, he explained. But in clinical practice, some patients and their doctors decide to stop the therapy a few months earlier if the patient is in remission and has a mild, but bothersome side effect.Apr 30, 2021
How long is a course of immunotherapy?
Many people stay on immunotherapy for up to two years. Checkpoint inhibitors can take weeks or months to start working, depending on how your immune system and the cancer respond. Most cancers have treatment protocols that set out which drugs to have, how much and how often.

Data suggest that stopping immunotherapy after 1 year of treatment could lead to inferior progression-free survival and overall survival, says Lopes. However, stopping after 2 years does not appear to negatively impact survival.May 20, 2020
How long does immunotherapy extend life?
In a study led by UCLA investigators, treatment with the immunotherapy drug pembrolizumab helped more than 15 percent of people with advanced non-small cell lung cancer live for at least five years — and 25 percent of patients whose tumor cells had a specific protein lived at least that long.

Can you have immunotherapy for more than 2 years?
Like most lung cancer treatments, immunotherapy is only given for a set period of time. Immunotherapy is given for a maximum of two years. After then, it will be stopped.
What is PD-1 in melanoma?
Monotherapy with immune checkpoint inhibitors, specifically those targeting programmed death 1 (PD-1), has revolutionized the treatment of metastatic melanoma: approximately 40% of patients achieve a partial or complete response, many of which are durable. However, a subset of patients who initially respond to therapy will progress, ...
What is immune checkpoint blockade?
The use of immune checkpoint blockade has revolutionized the treatment of metastatic melanoma, with dramatic improvements in cancer-related outcomes since the advent of these agents. Long-term survival data demonstrate durable disease control in 20% and 30% of patients receiving the cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) antagonist ipilimumab and the programmed death 1 (PD-1) inhibitor pembrolizumab, respectively. [1,2] However, a subset of patients-approximately 40% to 45%-experience no response to therapy, with clear de novo resistance (primary resistance). The reasons for primary resistance include inadequate T-cell infiltration into the tumor, as well as immunosuppressive factors within the tumor microenvironment. [3,4] Treatment strategies to overcome these obstacles range from adoptive T-cell therapy to stimulate tumor antigen–specific T cells, to mitogen-activated protein kinase (MAPK) inhibition to improve T-cell trafficking into the tumor. [5]
Does PD-1 inhibitor have immunomodulatory properties?
Targeting angiogenesis may also be an effective strategy to increase the efficacy of PD-1/PD-L1 inhibitors, since emerging data suggest that these agents possess immunomodulatory properties that may potentiate a durable immune response and/or overcome resistance. [64] A phase I study of combination bevacizumab and ipilimumab in patients with metastatic melanoma demonstrated a DCR of 67%, with provocative correlative data showcasing an intense immune infiltration in on-treatment tumor biopsies. [64] This prompted several additional trials across tumor types (ClinicalTrials.gov identifier: NCT02681549), including renal cell carcinoma: the phase II IMmotion150 trial demonstrated an improvement in PFS for PD-L1–positive patients (PD-L1 expression ≥ 1%) treated with combination atezolizumab/bevacizumab vs atezolizumab monotherapy. [65] The efficacy and safety of atezolizumab plus bevacizumab is currently under exploration in untreated melanoma patients with brain metastases (ClinicalTrials.gov identifier: NCT03175432).
What are the primary and acquired resistance mechanisms?
Primary and acquired resistance mechanisms are often mediated by the immunosuppressive elements of the tumor microenvironment; therefore, modulation of these factors with agents such as phosphoinositide 3-kinase (PI3K)-γ and CSF1R inhibitors is another area of intense study. Inhibition of PI3K-γ has been shown to affect immunosuppressive macrophages and myeloid-derived stem cells (MDSCs), leading to an increase in cytotoxic T-cell activity. [59] A clinical trial (ClinicalTrials.gov identifier: NCT02637531) is currently exploring the combination of PI3K-γ inhibition and immune checkpoint inhibitor therapy in advanced solid tumor patients, including those with metastatic melanoma, who have progressed on standard therapies. Preliminary data demonstrate evidence of immune modulation and early signs of clinical activity, with an acceptable safety signal. [60]
Is immunotherapy a treatment for unresectable melanoma?
Immunotherapy has changed the treatment landscape for unresectable melanoma. However, despite the successes of front-line immune checkpoint inhibitor therapy, most patients will eventually progress. Post-progression treatment decisions should be made based on the site of progression, extent of disease progression, and clinical status of the patient. In the setting of oligometastatic progression, employment of local therapy with surgical resection or ablative radiotherapy is often preferred with continuation of immune checkpoint inhibitors. In contrast, transition to an alternative standard or investigational systemic agent (s) is required in cases of diffuse progression. The decision regarding next-line therapy requires assessment of both cancer- and patient-specific factors, such as the molecular features of the tumor (eg, BRAF mutation status), the performance status of the patient, and clinical trial availability. Advancements in translational biomarker research are crucial in order to refine this treatment algorithm. Pre- and on-treatment biomarker discovery will hopefully aid clinicians in identifying patients who are likely to respond to front-line monotherapy with immune checkpoint inhibitors; importantly, it will also help to provide further insights into the optimal therapeutic strategies for individuals with primary resistance and those destined to develop acquired resistance.
What is NKTR 214?
[66] However, severe toxicities, coupled with potential immunosuppressive effects, [67] have limited its use. NKTR-214, a pro-drug of IL-2, has subsequently been developed to generate the immune stimulatory benefits of the IL-2 pathway to maximize antitumor responses and minimize adverse effects. [68] Combination NKTR-214 and nivolumab was recently examined in the phase I/II PIVOT-02 study. Impressive results were seen in the treatment-naive melanoma cohort, with a reported ORR and DCR of 52% and 78%, respectively, with no increased safety signal. [69] There are several studies evaluating NKTR-214 with immune checkpoint inhibitor therapy in the first-line and second-line settings (ClinicalTrials.gov identifiers: NCT02983045 and NCT03138889).
What is a T cell transfer?
Adoptive T-cell transfer is a pioneering immunotherapy strategy and remains an innovative way to optimize T-cell immunity in metastatic melanoma. In this highly sophisticated technique, T lymphocytes are harvested from a patient, and tumor-specific T cells are generated, expanded in vitro, and ultimately re-infused into the patient, with the goal of eradicating tumor cells. Data demonstrate that these novel treatments can be an effective option for fit patients who have progressed on standard agents. [70] Notably, although chimeric antigen receptor (CAR) T-cell therapy is an area of intense interest due to successes seen in hematologic malignancies, the complexity of identifying a target antigen and overcoming immunosuppressive effects of the tumor microenvironment has limited the effectiveness of this therapy in the treatment of solid tumors. [71] Studies of CAR T-cell therapy are ongoing across solid malignancies, including melanoma (ClinicalTrials.gov identifiers: NCT02830724 and NCT03060356).
