Durvalumab
(IMFINZI®) + tremelimumab-actl (IMJUDO®) and platinum-based
chemotherapy is an NCCN Category 1, recommended first-line systemic therapy for
metastatic NSCLC without EGFR or ALK alterations with PD-L1 ≥1%-49% (Category 1 applies
to nonsquamous histology only) or PD-L1
<1%5‡
Study design: The POSEIDON trial was a Phase III, global, randomized (1:1:1), open-label, multicenter, clinical trial in 1013 patients with nonsquamous and squamous metastatic NSCLC. Eligible patients were treatment-naïve for metastatic disease, with no EGFR mutations or ALK genomic tumor aberrations, had an ECOG performance status of 0 or 1 and were stratified by PD-L1 (TC <50% vs TC ≥50%), histology, and disease stage (IVA, IVB). Patients received IMFINZI + IMJUDO and platinum-based chemotherapy* (n=338), platinum-based chemotherapy* (n=337), or IMFINZI + platinum-based chemotherapy* (unapproved use in mNSCLC; n=338). The major efficacy outcome measures were PFS and OS of IMFINZI + IMJUDO and platinum-based chemotherapy vs platinum-based chemotherapy alone. Secondary outcome measures included ORR and DoR. PFS, ORR, and DoR were assessed using BICR according to RECIST v1.1.1-3
*Platinum-based CT is given Q3W for 4 cycles. Options include pemetrexed + carboplatin/cisplatin (nonsquamous); gemcitabine + carboplatin/cisplatin (squamous); or nab-paclitaxel + carboplatin (either histology). Starting in Week 12, nonsquamous patients who received pemetrexed as part of the first-line regimen can continue pemetrexed maintenance Q4W until disease progression or intolerable toxicity.1,2
†The preplanned OS analysis was conducted after 536 deaths for 79.4% maturity.6

Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all
possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in
any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or
after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of
underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine,
adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of
suspected immune-mediated adverse reactions, initiate appropriate workup
to exclude alternative etiologies,
including infection. Institute medical management promptly, including specialty consultation as appropriate.
Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration
for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic
corticosteroid therapy (1 mg to 2 mg/kg/
day prednisone or equivalent) until improvement to Grade 1 or less. Upon
improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider
administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not
controlled with corticosteroid therapy.
IMFINZI, as a single agent, is indicated for the treatment of adult patients with unresectable Stage III non-small cell lung cancer (NSCLC) whose disease has not progressed following concurrent platinum-based chemotherapy and radiation therapy (cCRT).

IMFINZI and IMJUDO can cause immune-
mediated pneumonitis, which may be fatal. The
incidence of pneumonitis is higher in patients who have received prior thoracic radiation.
IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal. IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies.
IMFINZI and IMJUDO can cause immune-mediated hepatitis, which may be fatal.
IMFINZI and IMJUDO can cause immune-mediated nephritis.
IMFINZI and IMJUDO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), has occurred with PD-1/L-1 and CTLA-4 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes.
IMFINZI in combination with IMJUDO can cause immune-mediated pancreatitis. Immune-
mediated pancreatitis occurred in 2.3% (9/388) of patients receiving IMFINZI
and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions.
The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in patients who received IMFINZI and IMJUDO or were reported with the use of other immune-checkpoint inhibitors.
IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody.
Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/L-1 blocking antibody prior to or after an allogeneic HSCT.
Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO.
There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.
The safety and effectiveness of IMFINZI and IMJUDO have not been established in pediatric patients.
