"We significantly advanced the business on multiple fronts over the last 12 months, most notably with the accelerated approval and launch of ELAHERE for patients with platinum-resistant ovarian cancer," said Mark Enyedy, ImmunoGen’s President and Chief Executive Officer. "We have seen broad and deep adoption of ELAHERE to date, with FRα testing, managed care coverage, and provider access all exceeding our expectations. Building upon this progress and in line with our goal of obtaining full approval for ELAHERE in the US and expanding into Europe, we will imminently reach the requisite number of PFS events in the confirmatory MIRASOL trial and expect to announce top-line data in the second quarter. In parallel, we are pursuing our broader development program in support of moving ELAHERE into platinum-sensitive disease and positioning ELAHERE as the combination agent of choice in ovarian cancer."

Enyedy continued, "Turning to our second pivotal program, pivekimab sunirine, we presented promising findings from our triplet expansion cohorts in AML in an oral presentation at ASH (Free ASH Whitepaper) in December, and continued enrollment in the pivotal CADENZA trial in frontline BPDCN with top-line data in de novo patients anticipated in 2024. We are also progressing our earlier-stage portfolio with the completion of dose escalation in the Phase 1 study of IMGC936, while also having dosed the first patient in our Phase 1 trial for IMGN151 in January. Combining our commitment to advance our pipeline of novel ADCs along with driving the commercial uptake of ELAHERE in the US, we are well positioned for another exciting and productive year."

FINANCIAL RESULTS
Total revenues were $41.2 million for the quarter ended December 31, 2022 compared to $28.0 million for the quarter ended December 31, 2021, and $108.8 million for the year ended December 31, 2022 compared to $69.9 million for the year ended December 31, 2021. The increase in the quarter ended December 31, 2022 was primarily driven by one-time milestone payments achieved pursuant to the Company’s license and collaboration agreements with Huadong Medicine and Viridian Therapeutics. In addition to greater partner milestones achieved, the increase for the current year was driven by one-time license fees received pursuant to agreements executed with Eli Lilly and Magenta Therapeutics in 2022, as well as greater amortization in 2022 of the $40.0 million upfront fee previously received pursuant to the Company’s collaboration agreement with Huadong Medicine. The Company also recorded $2.6 million in net product revenue from sales of ELAHERE for the quarter and year ended December 31, 2022.

Research and development expenses rose to $58.5 million for the quarter ended December 31, 2022 compared to $49.0 million for the quarter ended December 31, 2021, and $213.4 million for the year ended December 31, 2022 compared to $151.1 million for the year ended December 31, 2021. The increases in both periods were driven by greater personnel and temporary staffing costs, external manufacturing costs, and third-party service fees, including medical affairs’ activities in support of the US commercial launch of ELAHERE in the fourth quarter of 2022, as well as greater clinical trial expenses. Additionally, research and development expenses for the year ended December 31, 2022 included $8.9 million of research costs to expand our ADC pipeline, inclusive of a one-time $7.5 million upfront fee paid to Oxford BioTherapeutics.

Selling, general and administrative expenses were $42.1 million for the quarter ended December 31, 2022 compared to $13.6 million for the quarter ended December 31, 2021, and $116.1 million for the year ended December 31, 2022 compared to $43.8 million for the year ended December 31, 2021. The increases in both periods were due primarily to building our commercial infrastructure and capabilities, including personnel-related costs and sales and marketing activities in support of the US launch of ELAHERE in the fourth quarter of 2022.

Net loss for the fourth quarter of 2022 was $59.0 million, or $0.23 per diluted share, compared to net loss of $37.2 million, or $0.17 per diluted share, for the fourth quarter of 2021. Net loss for the year ended December 31, 2022 was $222.9 million, or $0.88 per diluted share, compared to a net loss of $139.3 million, or $0.68 per diluted share, for the year ended December 31, 2021.

ImmunoGen had $275.1 million in cash and cash equivalents as of December 31, 2022, compared with $478.8 million as of December 31, 2021. Cash used in operations was $229.8 million for the year ended December 31, 2022 compared with $169.4 million for the year ended December 31, 2021. Capital expenditures were $1.4 million in each of the years ended December 31, 2022 and 2021.

During the quarter ended December 31, 2022, the Company sold 5.2 million shares of its common stock through its At-the-Market facility, generating net proceeds to the Company of $25.6 million.

FINANCIAL GUIDANCE
For 2023, ImmunoGen expects:

revenues, excluding product revenue from ELAHERE, between $30 million and $35 million; and
operating expenses between $310 million and $320 million.
ImmunoGen expects to provide ELAHERE product revenue guidance later this year.

Excluding anticipated ELAHERE and collaboration revenue, our level of cash and cash equivalents as of December 31, 2022, alone is not sufficient to meet our current operating plans through March 1, 2024. With the addition of forecasted ELAHERE product revenue and milestone payments under existing collaboration agreements, we expect these amounts combined with existing cash and cash equivalents will fund operations for more than 12 months from the date of this release. The Company intends to raise additional funds through equity, debt, or other financings.

CONFERENCE CALL INFORMATION
ImmunoGen will hold a conference call today at 8:00 a.m. ET to discuss these results. To access the live call by phone, please register here. A dial-in and unique PIN will be provided to join the call. The call may also be accessed through the Investors and Media section of the Company’s website, www.immunogen.com. Following the call, a replay will be available at the same location.

"Since the start of 2022, the G1 team has achieved the milestones we put forth at the beginning of the year and did so with the resolve expected of a company focused on the needs of the cancer patients we seek to treat," said Jack Bailey, Chief Executive Officer of G1 Therapeutics. "Since announcing the results of PRESERVE 1 last month, we’ve moved forward with urgency on the rest of the business. First, we remain confident in the small cell lung cancer business and have returned growth to COSELA sales through February 2023. Second, we are aggressively executing on our ongoing clinical trials, including the Phase 2 ADC and MOA trials in TNBC, each of which provided compelling initial results late in 2022 and have additional readouts expected in the second quarter of this year. And third, we have moved quickly to make necessary reductions to the organization and our expenses to extend our cash runway through each of our ongoing clinical trials."

Continued Bailey, "On behalf of the G1 team, I’d also like to express my gratitude to Jen Moses for her dedication to our company, our vision, and the patients we seek to treat. Jen has been with G1 since 2015 and became our Chief Financial Officer in 2019; her financial leadership throughout that period has been exceptional. We wish her continued success in her next professional chapter."

Fourth Quarter 2022 and Recent Highlights

Financial

Achieved $8.9 Million and $31.3 Million in Net COSELA Revenue for the Fourth Quarter and Full Year 2022: Results represent a 102% increase and a 182% increase over the corresponding periods in 2021. G1 recognized total revenues of $10.3 million and $51.3 million for the fourth quarter and full year of 2022, respectively.

Completed Public Offering Resulting in $52.0 Million in Net Proceeds: In November 2022, G1 closed an underwritten public offering of its common stock at a public offering price of $6.50 per share.

Ended the Fourth Quarter 2022 with Cash, Cash Equivalents, and Marketable Securities of $145.1 Million.
Clinical

Announced Top Line Results from Pivotal Phase 3 Trial of Trilaciclib in Patients Receiving FOLFOXIRI + Bevacizumab for Metastatic Colorectal Cancer (CRC) (PRESERVE 1): G1 announced top line results from its pivotal Phase 3 PRESERVE 1 trial showing that the trial achieved its co-primary endpoints related to severe neutropenia with statistical significance (p<0.001). These results further validate the myeloprotection benefit of trilaciclib. Despite the achievement of the co-primary endpoints and other secondary measures of myeloprotection and tolerability, early anti-tumor efficacy data, including overall response rate, favored patients receiving placebo compared to trilaciclib. Given the differential in these anti-tumor efficacy metrics and the low likelihood of achieving the progression-free survival and overall survival (OS) endpoints, G1 has discontinued PRESERVE 1. (Press release here)

Completed Enrollment in Pivotal Phase 3 Clinical Trial of Trilaciclib in Patients with mTNBC: Enrollment in PRESERVE 2 is complete at 187 patients receiving first line trilaciclib or placebo prior to gemcitabine and carboplatin (GC). The primary endpoint is to evaluate the effect of trilaciclib on OS compared with placebo in patients receiving first-line GC (press release here). The interim OS analysis will be conducted by its data monitoring committee at 70% of events. Based on recent evaluations, the number of actual events appears to be occurring more slowly than predicted. As a result, G1 now expects the interim OS analysis to be conducted in the first half of 2024. If the trial meets the interim analysis stopping rule, it will terminate, and G1 will report the top line results. If it does not, the trial will continue to the final analysis.

Announced Initial Results from Phase 2 Trial of Trilaciclib in Combination with an Antibody-Drug Conjugate: Initial Phase 2 safety data suggest on-target effect of trilaciclib to reduce (>50%) the rates of adverse events associated with the ADC sacituzumab govitecan-hziy, including myelosuppression and diarrhea, relative to the previously published sacituzumab single agent safety profile. The Company anticipates disclosure of a more comprehensive data set including safety and initial efficacy results at a medical meeting in the second quarter 2023. (Press release here)

Confirmed that Initial Results Including the Primary Endpoint of Progression Free Survival from Phase 2 Bladder Cancer Trial of Trilaciclib (PRESERVE 3) Are Anticipated Midyear 2023: G1 has reiterated that additional safety and efficacy results, including results from the primary endpoint of Progression Free Survival, are expected from PRESERVE 3 midyear 2023. (Press release here)
Medical

Presented Results from Phase 2 Mechanism of Action Trial at the San Antonio Breast Cancer Symposium (SABCS) Showing That Trilaciclib Favorably Alters the Tumor Microenvironment: G1 provided initial results from a 24 patient Phase 2 mechanism of action (MOA) trial showing favorable alterations in the tumor microenvironment from a single dose of trilaciclib monotherapy as measured by increases in the proportions of CD8+ T cells compared to T regulatory cells (Tregs) in patients with early-stage triple negative breast cancer (TNBC). (Press release here)

Presented Nonclinical Study Results at the 2022 Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Conference Elucidating Immune Effects of Trilaciclib: New nonclinical data show that trilaciclib upregulates key processes within the cancer immunity cycle including that trilaciclib enhances the differentiation of CD8+ T cells into effector memory and central memory T cell populations. In addition, trilaciclib can increase antigen presentation on tumor cells by upregulating HMC Class I and II, and promote T cell recruitment to tumor cells. (Press release here)
Corporate

Reduced Headcount and Associated Expenses to Extend Cash Runway Beyond Clinical Trial Readouts: G1 completed a reduction in force of approximately 30%, though the COSELA sales team remains intact. As a result of this and other reductions in spend, G1 currently expects its 2023 operating expense to be 20% to 30% lower than that of 2022. With these adjustments to operating expenses, the top line guidance provided, and other assumptions around partner revenue, the Company believes this extends its cash runway through its upcoming readouts from its ongoing clinical trials.

Announced Executive Succession Plan: Jen Moses, G1’s Chief Financial Officer, will resign as of March 15, 2023, and will remain a senior advisor to the organization for one year. As of the date of her departure, G1’s Controller John W. Umstead V will be appointed to the role of CFO. Mr. Umstead has been with the Company since 2018. Prior to joining the Company, Mr. Umstead worked for PricewaterhouseCoopers LLP serving clients in various industries ranging from small private companies to large publicly traded corporations in a number of roles of increasing responsibility.
Fourth Quarter and Full Year 2022 Financial Results

As of December 31, 2022, cash and cash equivalents and marketable securities totaled $145.1 million, compared to $221.2 million as of December 31, 2021.

GAAP operating expenses include stock-based compensation expense of $4.4 million for the fourth quarter of 2022, compared to $5.2 million for the fourth quarter of 2021. Operating expenses for the full year 2022 were $187.5 million, compared to $173.9 million for the prior year. Stock-based compensation expense for the full year 2022 was $20.6 million, compared to $22.3 million for the prior year.

Cost of goods sold expense for the fourth quarter of 2022 was $1.0 million compared to $0.4 million for the fourth quarter of 2021, primarily due to an increase in product sales. Cost of goods sold expense for the full year 2022 was $3.7 million, compared to $2.0 million for the prior year.

Research and development (R&D) expenses for the fourth quarter of 2022 were $16.6 million, compared to $19.8 million for the fourth quarter of 2021. The decrease in R&D expenses was primarily due to a decrease in the Company’s clinical program costs. R&D expenses for the full year 2022 were $83.3 million, compared to $76.2 million for the prior year.

Selling, general, and administrative (SG&A) expenses for the fourth quarter of 2022 were $23.6 million, compared to $23.2 million for the fourth quarter of 2021. The increase in SG&A expenses was due to increases in personnel costs and was offset by a decrease in payments to Boehringer Ingelheim and decreased professional and administrative expenses. SG&A expenses for the full year 2022 were $100.4 million, compared to $95.7 million for the prior year.

The net loss for the fourth quarter of 2022 was $33.6 million, compared to $40.0 million for the fourth quarter of 2021.

Merck Announces Phase 3 KEYNOTE-671 Trial Met Primary Endpoint of Event-Free Survival (EFS) in Patients With Resectable Stage II, IIIA or IIIB Non-Small Cell Lung Cancer

On March 1, 2023 Merck (NYSE: MRK), known as MSD outside of the United States and Canada, reported that the Phase 3 KEYNOTE-671 trial investigating KEYTRUDA, Merck’s anti-PD-1 therapy, met one of its dual primary endpoints, event-free survival (EFS), as a perioperative treatment regimen for patients with resectable stage II, IIIA or IIIB non-small cell lung cancer (NSCLC) (Press release, Merck & Co, MAR 1, 2023, View Source [SID1234627925]). A perioperative treatment regimen includes treatment before surgery (neoadjuvant) and continued after surgery (adjuvant). The trial will continue to evaluate the other dual primary endpoint of overall survival (OS).

At a prespecified interim analysis conducted by an independent Data Monitoring Committee, neoadjuvant KEYTRUDA plus chemotherapy followed by resection and adjuvant single-agent KEYTRUDA demonstrated a statistically significant and clinically meaningful improvement in EFS compared to neoadjuvant placebo plus chemotherapy followed by adjuvant placebo. Statistically significant improvements in the trial’s key secondary endpoints of pathological compete response (pCR) and major pathological response (mPR) were also demonstrated at this analysis. No new safety signals were observed.

Results will be presented at an upcoming medical meeting. The U.S. Food and Drug Administration (FDA) has accepted Merck’s new supplemental Biologics License Application (sBLA) based on these data for KEYTRUDA for the treatment of patients with resectable stage II, IIIA, or IIIB (T3-4N2) NSCLC in combination with platinum containing chemotherapy as neoadjuvant treatment, and then continued as a single agent as adjuvant treatment. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of October 16, 2023.

"Results from KEYNOTE-671 show that KEYTRUDA in combination with chemotherapy provided significant improvement in event-free survival, pathological complete response and major pathological response over chemotherapy alone as a perioperative treatment regimen for patients with resectable stage II, IIIA or IIIB non-small cell lung cancer," said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories. "By moving this KEYTRUDA-based regimen into earlier stages of non-small cell lung cancer, we may be able to significantly reduce the risk of recurrence for these patients. This study is an important milestone, and we look forward to sharing the detailed results with the medical community as soon as possible. We thank the patients and investigators for their important contributions to this study."

Merck has an extensive clinical development program in lung cancer and is advancing multiple registration-enabling studies, with research directed at earlier stages of disease and novel combinations. Key studies in earlier stages of NSCLC include KEYNOTE-671, KEYNOTE-091, KEYNOTE-867, KEYLYNK-012 and KEYVIBE-006.

About KEYNOTE-671
KEYNOTE-671 is a randomized, double-blind Phase 3 trial (ClinicalTrials.gov, NCT03425643) evaluating neoadjuvant KEYTRUDA plus chemotherapy, followed by adjuvant KEYTRUDA as a single agent versus placebo plus neoadjuvant chemotherapy followed by adjuvant placebo in patients with resectable stage II, IIIA or IIIB (T3-4N2) NSCLC. The trial’s dual primary endpoints are EFS and OS. Key secondary endpoints include pCR and mPR. The study enrolled 786 patients who were randomly assigned (1:1) to receive either:

KEYTRUDA (200 mg intravenously [IV] every three weeks [Q3W] for up to four cycles) plus chemotherapy (cisplatin [75 mg/m^2, IV; given on Day 1 of each cycle] and either gemcitabine [1000 mg/m^2, IV; given on Days 1 and 8 of each cycle) or pemetrexed [500 mg/m^2, IV; given on Day 1 of each cycle]) as neoadjuvant therapy prior to surgery, followed by KEYTRUDA (200 mg IV Q3W for up to 13 cycles) as adjuvant therapy post-surgery, or;

About lung cancer
Lung cancer is the leading cause of cancer death worldwide. In 2020 alone, there were more than 2.2 million new cases and 1.8 million deaths from lung cancer globally. Non-small cell lung cancer is the most common type of lung cancer, accounting for about 81% of all cases. In the U.S., the overall five-year survival rate for patients diagnosed with lung cancer is 25%, which is a 21% improvement over the last five years. Improved survival rates are due, in part, to earlier detection and screening, reduction in smoking, advances in diagnostic and surgical procedures, as well as the introduction of new therapies. Early detection and screening remain an important unmet need, as 44% of lung cancer cases are not found until they are advanced. Only 5.8% of people in the U.S. who are eligible were screened for lung cancer in 2021.

About Merck’s research in lung cancer
Merck is advancing research aimed at transforming the way lung cancer is treated, with a goal of improving outcomes for patients affected by this deadly disease. Through nearly 200 clinical trials evaluating more than 36,000 patients around the world, Merck is at the forefront of lung cancer research. In NSCLC, KEYTRUDA has five approved U.S. indications (see indications below) and is approved for advanced disease in more than 95 countries. Among Merck’s research efforts are trials focused on evaluating KEYTRUDA in earlier stages of lung cancer as well as identifying new combinations and coformulations with KEYTRUDA.

About Merck’s early-stage cancer clinical program
Finding cancer at an earlier stage may give patients a greater chance of long-term survival. Many cancers are considered most treatable and potentially curable in their earliest stage of disease. Building on the strong understanding of the role of KEYTRUDA in later-stage cancers, Merck is studying KEYTRUDA in earlier disease states, with approximately 20 ongoing registrational studies across multiple types of cancer.

About KEYTRUDA (pembrolizumab) injection, 100 mg
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 1,600 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA
Severe and Fatal Immune-Mediated Adverse Reactions
KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the PD-1 or the PD-L1, blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. 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 KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 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 adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis
KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.

Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.

Pneumonitis occurred in 41 (7%) patients, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. In adult patients who received adjuvant therapy for NSCLC, patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution.

Immune-Mediated Colitis
KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus 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. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.

Hepatotoxicity and Immune-Mediated Hepatitis
KEYTRUDA as a Single Agent
KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.

KEYTRUDA With Axitinib
KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT ≥3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT ≥3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT ≥3 ULN subsequently recovered from the event.

Other Immune-Mediated Adverse Reactions
The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received KEYTRUDA or were reported with the use of other anti–PD-1/PD-L1 treatments. Severe or fatal cases have been reported for some of these adverse reactions. Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: Myositis/polymyositis, rhabdomyolysis (and associated sequelae, including renal failure), arthritis (1.5%), polymyalgia rheumatica; Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

Infusion-Related Reactions

Monitor for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1 or Grade 2 reactions. For Grade 3 or Grade 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)
Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after anti–PD-1/PD-L1 treatments. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between anti–PD-1/PD-L1 treatment and allogeneic HSCT. Follow patients closely for evidence of these complications and intervene promptly. Consider the benefit vs risks of using anti–PD-1/PD-L1 treatments prior to or after an allogeneic HSCT.

Increased Mortality in Patients With Multiple Myeloma
In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with an anti–PD-1/PD-L1 treatment in this combination is not recommended outside of controlled trials.

Embryofetal Toxicity
Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.
