"A key reason for conducting the TAMARACK study was to test the hypothesis that we could improve upon the duration of vobra duo treatment observed in the Phase 1 study by reducing the starting dose from 3.0 mg/kg to either 2.0 or 2.7 mg/kg and increasing the dosing interval from every three weeks to every four weeks. In doing so, our aim was to improve safety and tolerability, extend the treatment duration and achieve improved rPFS as compared to the result in our Phase 1 mCRPC dose expansion cohort," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "We believe that these latest results from TAMARACK continue to demonstrate that vobra duo is an active drug in prostate cancer. Ultimately, our path forward for the molecule will depend on the final safety and efficacy data, including mature median rPFS, which we expect to have in hand no later than early 2025. We expect to make decisions about potential future development in the context of a competitive treatment landscape assessment, resource allocation across our clinical portfolio and potential partnering opportunities for vobra duo."

TAMARACK Study Demographics

The abstract submitted to ESMO (Free ESMO Whitepaper) was based on a data cut-off as of April 12, 2024; updated data based on a cut-off date of July 9, 2024, are included below and are reported in the Company’s poster presentation at ESMO (Free ESMO Whitepaper).

The TAMARACK trial enrolled a total of 181 participants, with 176 participants receiving at least one dose of vobra duo at either 2.0 mg/kg q4W (n=90) or 2.7 mg/kg q4W (n=86). As of the data cut-off date, 23 and 16 participants remained on treatment in the 2.0 mg/kg and 2.7 mg/kg cohorts, respectively. While mCRPC study participants are no longer being dosed in the study, participants continue to be monitored for adverse events, disease progression, and survival.

Baseline Characteristics:

Enrolled study participants had a median age of 70 years (range, 35-89).
88 Study participants (48.6%) had an ECOG performance status of 1 or 2.
30 Study participants (16.6%) had visceral disease at baseline, with liver or lung disease in 25 participants (13.8%).
81 Study participants (44.8%) had measurable disease at baseline, and 97 (53.6%) had received prior taxane.
Both treatment arms were well-balanced across most baseline characteristics, including prior use of taxanes, androgen receptor axis-targeted (ARAT) treatment, poly-ADP ribose polymerase (PARP) treatment, and baseline PSA.
TAMARACK Efficacy Results as of July 9, 2024 Cut-off Date

Overall, the Company believes that the results to date from the TAMARACK study indicate antitumor activity associated with vobra duo in mCRPC as demonstrated by the protocol-specified primary endpoint of landmark 6-month radiographic progression-free survival (rPFS) rate, as well as other measures of tumor response.

In the intent-to-treat (ITT) population, 6-month rPFS rate was 69% for the 2.0 mg/kg arm (95% CI, 57-79) and 70% for the 2.7 mg/kg arm (95% CI, 58-79).
Landmark 6-month rPFS rates were consistent across taxane-naïve study participants (ranging from 66-82%) and taxane pre-treated study participants (ranging from 60-73%), regardless of treatment arm.
Although immature, with only 65 PFS events (35.9%) as of the data cut-off, median rPFS was approximately 8.5 months for the 2.0 mg/kg cohort (95% CI, 7.2-11.2) and 7.5 months for the 2.7 mg/kg cohort (95% CI, 7.2-10.6). Because these results were immature as of the cutoff date, they are likely to change as additional events accrue.
Tumor response rates

Out of 45 RECIST-response evaluable patients in the 2.0 mg/kg arm, the confirmed objective response rate (ORR) was 20.0% (n=9) and the unconfirmed ORR was 26.7% (n=12).
Out of 32 RECIST-response evaluable patients in the 2.7 mg/kg arm, the confirmed ORR was 40.6% (n=13) and the unconfirmed ORR was 46.9% (n=15).
Confirmed ORR was comparable between taxane-naïve study participants (26.7%, n=12/45) and taxane pre-treated study participants (17.5%, n=11/63), regardless of treatment arm.
Tumor responses did not appear to correlate with baseline B7-H3 expression based on archival tissue samples of mixed age.
TAMARACK Safety Results as of July 9, 2024 Cut-off Date

Overall summary of adverse events (AEs)

In the 2.0 mg/kg cohort, 65.6% of study participants (n=59) experienced a Grade ≥3 treatment-emergent AE (TEAE); this cohort had a discontinuation rate of 25.6% (n=23) and a dose reduction rate of 50.0% (n=45) due to TEAEs.
In the 2.7 mg/kg cohort, 62.8% of study participants (n=54) experienced a Grade ≥3 TEAE; this cohort had a discontinuation rate of 38.4% (n=33) and a dose reduction rate of 54.7% (n=47) due to TEAEs.
The most common (occurring in ≥20% of study participants) all-grade TEAEs were: asthenia, edema peripheral, decreased appetite, nausea, pleural effusion, diarrhea, fatigue, constipation, anemia, palmar-plantar erythrodysesthesia (PPE, or hand-foot syndrome), neutropenia, and stomatitis. The majority of TEAEs with a ≥10% incidence rate in either treatment arm was limited to Grade 1/2 events.
Rates of pleural effusion, pericardial effusion, and PPE for both the 2.0 mg/kg cohort (28.8%, 13.3%, 18.9%, respectively) and the 2.7 mg/kg cohort (44.2%, 17.5%, 28%, respectively) decreased compared to the Phase 1 mCRPC dose expansion cohort (48.8%, 17.1%, 46.3%, respectively), despite an increased median number of doses of vobra duo administered on TAMARACK.
Eight fatal treatment-related AEs as assessed by the treating physician: five in the 2.0 mg/kg cohort and three in the 2.7mg/kg cohort. These include three events of pneumonitis, and one event each of cardiac failure, stress cardiomyopathy, ventricular fibrillation, pleural effusion, and gastrointestinal hemorrhage.
Rates of treatment-related AEs (including all grades and Grade ≥3) and treatment-related severe AEs were similar between taxane-naïve and taxane pre-treated study participants.
Tolerability findings

In the 2.0 mg/kg cohort, 25.6% of study participants (n=23) remained on study drug as of July 9, 2024. Study participants received a median number of 6 doses (range, 1-11), with a median dose intensity (calculated as a percentage of the total planned dose that was administered) of 92.6% (range, 64.2-106.1%).
In the 2.7 mg/kg cohort, 18.6% of study participants (n=16) remained on study drug as of the data cut-off date. Study participants received a median number of 6 doses (range, 1-12), with a median dose intensity of 81.7% (range, 40.5-104.3%).
Taxane-naïve study participants experienced higher rates of dose reductions due to TEAEs (62.7%) and dose interruptions due to TEAEs (70.7%) compared to taxane pre-treated study participants (44.6% and 43.6%, respectively).

About Vobra Duo and the TAMARACK Study

Vobra duo is an antibody-drug conjugate (ADC) that targets B7-H3, an antigen with broad expression across multiple solid tumors and a member of the B7 family of molecules involved in immune regulation. The TAMARACK Phase 2 study of vobra duo is being conducted in participants with mCRPC who were previously treated with one prior androgen receptor axis-targeted therapy (ARAT). Participants may have received up to one prior taxane-containing regimen, but no other chemotherapy agents. The TAMARACK study is designed to evaluate vobra duo at two different doses: 2.0 mg/kg or 2.7 mg/kg every four weeks (q4W).

Ipsen provides update on CONTACT-02 Phase III trial in metastatic castration-resistant prostate cancer following final overall survival analysis

On September 15, 2024 Ipsen reported detailed final overall survival (OS) data from the Phase III CONTACT-02 trial investigating the combination of Cabometyx (cabozantinib) and atezolizumab in metastatic castration-resistant prostate cancer (mCRPC) (Press release, Ipsen, SEP 15, 2024, View Source [SID1234646611]). The trial investigated the combination regimen versus a second novel hormonal therapy (NHT) in men previously treated with one NHT and measurable soft-tissue disease. At a median follow-up of 24.0 months, these data demonstrated a numerical but not statistically significant improvement in OS for the combination versus a second NHT (hazard ratio: 0.89; 95% confidence interval: 0.72-1.10; P=0.296). As previously announced, the trial met the other primary endpoint of progression-free survival (PFS), demonstrating a statistically significant benefit in PFS.1 Safety for the combination appeared to be consistent with the known safety profiles of the individual medicines, and no new safety signals were identified.

About Cabometyx

Cabometyx (cabozantinib) is a small molecule that inhibits multiple receptor tyrosine kinases, including VEGFRs, MET, RET and the TAM family (TYRO3, MER, AXL).2 These receptor tyrosine kinases are involved in both normal cellular function and pathologic processes such as oncogenesis, metastasis, tumor angiogenesis (the growth of new blood vessels that tumors need to grow), drug resistance, modulation of immune activities and maintenance of the tumor microenvironment.2,3,4,5

Exelixis granted Ipsen exclusive rights for the commercialization and further clinical development of Cabometyx outside of the U.S. and Japan. Exelixis granted exclusive rights to Takeda Pharmaceutical Company Limited (Takeda) for the commercialization and further clinical development of Cabometyx for all future indications in Japan. Exelixis holds the exclusive rights to develop and commercialize Cabometyx in the U.S.

In over 65 countries outside of the United States and Japan, including in the European Union, Cabometyx is currently indicated as a:3

Monotherapy for advanced renal cell carcinoma (aRCC).
as first-line treatment of adults with intermediate- or poor-risk disease.
in adults following prior VEGFR-targeted therapy.
A combination with nivolumab for the first-line treatment of aRCC in adults.
Monotherapy for the treatment of adults living with locally advanced or metastatic differentiated thyroid carcinoma, refractory or not eligible to radioactive iodine who have progressed during or after prior systemic therapy.
Monotherapy for the treatment of hepatocellular carcinoma in adults who have previously been treated with sorafenib.
The detailed recommendations for the use of Cabometyx are described in the Summary of Product Characteristics (EU SmPC).

About mCRPC

Prostate cancer is the second most common cancer in men and the fourth most common cancer overall globally.6 In 2020, there were more than 1.4 million new cases of prostate cancer and about 375,300 deaths worldwide.6 Prostate cancer is considered mCRPC when it has spread beyond the prostate and does not respond to androgen-suppression therapies, a common treatment for prostate cancer.7 Men diagnosed with mCRPC often have a poor prognosis, with an estimated survival of 1-2 years.8

About CONTACT-02

CONTACT-02 is a global, multicenter, randomized, Phase III, open-label study that enrolled 575 patients who were randomized 1:1 to the experimental arm of Cabometyx in combination with atezolizumab and the control arm of a second NHT (either abiraterone and prednisone or enzalutamide). The study included patients with mCRPC who have measurable extra-pelvic soft tissue metastasis and who have progressed on one prior NHT. The two primary endpoints of the trial are progression-free survival (PFS) and OS. The PFS analysis was conducted in the first 400 randomized patients (PFS in the intent-to-treat [ITT] population) and assessed by a blinded independent radiology committee (BIRC) per RECIST 1.1. The OS analysis was conducted in the ITT population (n=507). The secondary endpoint is objective response rate (ORR) per BIRC. The trial is sponsored by Exelixis and co-funded by Ipsen, Roche and Takeda. Takeda is conducting the trial in Japan. More information about CONTACT-02 is available at ClinicalTrials.gov.

Investigational Rinatabart Sesutecan (Rina-S) Shows Promising Anti-Tumor Activity as Single Agent in Heavily Pretreated Patients with Ovarian and Endometrial Cancers in Phase 1/2 Clinical Trial

On September 15, 2024 Genmab A/S reported new data from the Phase 1/2 study of rinatabart sesutecan (Rina-S), an investigational folate receptor-alpha (FRα)-targeted, Topo1 antibody-drug conjugate (ADC), demonstrated a confirmed objective response rate (ORR) of 50.0% (95% CI) in ovarian cancer patients treated with Rina-S 120 mg/m2 once every 3 weeks (Q3W), regardless of FRα expression levels (Press release, Genmab, SEP 15, 2024, View Source [SID1234646610]). These data were from the dose expansion part of a multi-part study evaluating the safety and efficacy of single-agent Rina-S in ovarian cancer (OC) and endometrial cancer (EC). These results, and additional findings from the study, were presented at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2024 (ESMO) (Free ESMO Whitepaper) in Barcelona, Spain.

Part B of the study randomized 42 previously-treated patients with histologically or cytologically confirmed advanced OC (epithelial ovarian cancer, primary peritoneal cancer or fallopian tube cancer) to Rina-S 100 mg/m2 (n=22) or Rina-S 120 mg/m2 (n=20). Ninety-five percent of patients in the 120 mg/m2 group were identified as platinum-resistant ovarian cancer (PROC) as were 90.9% of patients in the 100 mg/m2 group. In patients receiving Rina-S 100 mg/m2, results showed a confirmed ORR of 18.2% compared with 50.0% among patients receiving 120 mg/m2. Results for 100 mg/m2 and 120 mg/m2 respectively also included: complete response: 0 (0%) and 1 (5.6%); partial response in 4 (18.2%) and 8 patients (44.4%); stable disease in 15 (68.2%) and 7 patients (38.9%); disease progression in 3 patients (13.6%) and 1 patient (5.6%). Only one patient in the 120 mg/m2 treatment arm was not evaluable. With a median on study follow-up of 24 weeks, all confirmed responses with the 120 mg/m2 dose were ongoing at the time of data cutoff. The disease control rate (DCR) was 86.4% and 88.9% (95% CI: 65.3-98.6), respectively. Based on these results, Rina-S 120 mg/m2 has been selected for further evaluation in a Phase 3 trial for patients with advanced ovarian cancer, which is expected to start in 2024.

"Ovarian cancer presents a significant challenge, especially for those with advanced or recurrent cases, where treatment options and prognosis are often limited," said Elizabeth Lee, MD, a medical oncologist in the gynecologic oncology program at Dana-Farber. "The encouraging Phase 1/2 data for Rina-S demonstrates the potential for future treatment options for patients. We are looking forward to additional data from tumor-specific dose expansion cohorts."

In this Phase 1/2 study, common treatment-emergent adverse events (TEAEs) included anemia, neutropenia, nausea, thrombocytopenia, leukopenia, fatigue, vomiting, alopecia, and diarrhea. Dose reductions and treatment discontinuations were infrequent. No signals of ocular toxicities, neuropathy or interstitial lung disease (ILD) were observed.

"We are encouraged by the data from this ongoing Phase 1/2 trial evaluating Rina-S in a patient population that is in need of new therapeutic options and believe the data support the potential for Rina-S to demonstrate anti-tumor activity beyond first-generation folate receptor-alpha based therapies," said Jan van de Winkel, Ph.D., President and Chief Executive Officer of Genmab. "Genmab is pioneering technologies that aim to transform the treatment of cancer and other serious diseases. We are committed to evaluating the full potential utility of Rina-S in patients with ovarian, endometrial and other solid tumor cancers."

About Rina-S Phase 1/2 Clinical Trial (NCT05579366)
This open-label, multicenter Phase 1/2 study is designed to evaluate the safety and efficacy of rinatabart sesutecan (Rina-S) as a single agent Q3W at various doses in solid tumors that are known to express FRα. The study consists of multiple parts including Part A dose-escalation cohorts; Part B tumor-specific monotherapy dose-expansion cohorts; Part C platinum-resistant ovarian cancer (PROC) cohort; and Part D combination therapy cohorts.

Part A looked at dose escalation in patients with locally advanced and/or metastatic solid tumors, including epithelial ovarian cancer, endometrial cancer, breast cancer, non-small cell lung cancer, and mesothelioma. In patients with OC (n=32) and EC (n=11), treatment with Rina-S 100-120 mg/m2 (n=23 and n=5, respectively) demonstrated a confirmed Objective Response Rate (ORR) of 30.8% (95% CI: 14.3-51.8) with Partial Responses (PR) in 8 patients (30.8%), Stable Disease (SD) in 15 patients (57.7%), and Progressive Disease (PD) in 3 patients (11.5%). The Disease Control Rate (DCR) was 88.5% (95% CI: 69.8-97.6), and the median Duration of Response (DOR) was 35.3 weeks (95% CI: 20.14-NE).

Part B includes the B1 cohort, which is a dose expansion study in patients with histologically or cytologically confirmed advanced OC (epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer). Patients were randomized 1:1 to 100 mg/m2 and 120 mg/m2 dose groups with a median age ranging from 62.5 to 64.5 years across both groups. Ninety-point nine percent of patients in the 100 mg/m2 group were identified as platinum-resistant ovarian cancer (PROC) as were 95% of patients in the 120 mg/m2 group. Study participants were previously treated with a median of 3 prior lines of therapy (range 1-4) including bevacizumab (90.9% in the 100 mg/m2 group and 90.0% in the 120 mg/m2 group respectively), PARP inhibitors (68.2%; 65%) and mirvetuximab soravtansin (18.2%; 19%). Responses in patients with OC were observed across FRα expression levels.

About Ovarian Cancer
Ovarian cancer is a major global health issue, with over 320,000 new cases diagnosed annually worldwide.i It ranks as the eighth most common cancer and the eighth leading cause of cancer-related deaths among women globally.ii The disease is often diagnosed at an advanced stage due to its subtle and non-specific symptoms, such as abdominal bloating, pelvic pain and difficulty eating.iii Platinum-based chemotherapy, often in combination with targeted therapies and surgery, has been the standard treatment in ovarian cancer across all stages.iv,v Approximately 70-90% of women with advanced-stage ovarian cancer worldwide experience a recurrence after initial treatment.vi Ovarian cancer has a low five-year survival rate, which varies significantly by region, but generally hovers around 30-50%.vii,viii

About Rinatabart Sesutecan (Rina-S; GEN1184)
Rinatabart Sesutecan (Rina-S; GEN1184) is a clinical-stage, FRα-targeted, Topo1 ADC, currently in Phase 2 development for the treatment of ovarian cancer and other FRα-expressing solid tumors. Based on the data from the ongoing clinical trials, Genmab intends to broaden the development plans for Rina-S within ovarian cancer and other FRα-expressing solid tumors. In January 2024, the U.S. Food and Drug Administration granted Fast Track designation to Rina-S for the treatment of patients with FRα-expressing high-grade serous or endometrioid platinum-resistant ovarian cancer.

Bristol Myers Squibb Presents Landmark 10-Year Follow-Up Data from CheckMate -067 Which Showed Continued Durable Long-Term Survival Benefit with Opdivo® plus Yervoy® in Advanced Melanoma

On September 15, 2024 Bristol Myers Squibb reported 10-year follow-up data from CheckMate -067, a randomized, double-blind, Phase 3 clinical trial, which showed continued durable improvement in survival with first-line Opdivo (nivolumab) plus Yervoy (ipilimumab) therapy and Opdivo monotherapy, versus Yervoy alone, in patients with previously untreated advanced or metastatic melanoma (Press release, Bristol-Myers Squibb, SEP 15, 2024, View Source;067-Which-Showed-Continued-Durable-Long-Term-Survival-Benefit-with-Opdivo-plus-Yervoy-in-Advanced-Melanoma/default.aspx [SID1234646608]).

With a minimum follow up of 10 years, median overall survival (OS) was 71.9 months with Opdivo plus Yervoy (95% CI: 38.2-114.4) – the longest reported median OS in a Phase 3 advanced melanoma trial – 36.9 months with Opdivo (95% CI: 28.2-58.7) and 19.9 months with Yervoy (95% CI: 16.8-24.6). These data are being presented today and were included in an official press conference at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2024 in Barcelona, Spain (LBA43), as well as simultaneously published in The New England Journal of Medicine .

Among all randomized patients in the trial, 64% of patients who received the combination, 50% of Opdivo -treated patients and 33% of Yervoy -treated patients did not receive subsequent systemic therapy at the 10-year follow up mark.

"These data continue to demonstrate the impressive and durable clinical benefit of nivolumab in combination with ipilimumab with survival curves remaining stable for some years now," said James Larkin, Ph.D., FRCP, Consultant Medical Oncologist, Department of Medical Oncology, The Royal Marsden. "Remarkably, 43% of patients treated with nivolumab and ipilimumab are alive ten years later and many did not need subsequent therapy."

In addition, at 10 years of follow up, the Opdivo plus Yervoy combination showed melanoma-specific survival (MSS) rates of 52% (median not reached) compared to 44% (median of 49.4 months) and 23% (median of 21.9 months) among patients treated with Opdivo alone and Yervoy alone, respectively.

"Just over a decade ago, an advanced melanoma diagnosis meant that you likely only had months to live. The dual immunotherapy combination of Opdivo plus Yervoy has radically changed this outlook for many of these patients," said Dana Walker, M.D., M.S.C.E., vice president, global program lead, melanoma and gastrointestinal and genitourinary cancers, Bristol Myers Squibb. "Our goal was – and still is today – to redefine survival expectations for patients with melanoma; these data demonstrate our commitment to that objective and continue to provide hope."

Durable, sustained clinical benefit was also observed with Opdivo plus Yervoy or Opdivo alone across relevant subgroups, including in patients with BRAF mutation and wild-type tumors. Among patients with BRAF -mutant tumors, the rate of OS at 10 years was 52% (95% CI: 42-62) in patients who received Opdivo plus Yervoy , 37% (95% CI: 27-46) for Opdivo alone, and 25% (95% CI: 17-34) for Yervoy alone. In patients with BRAF wild-type tumors, the rate of OS at 10 years was 39% (95% CI: 32-46) in patients who received Opdivo plus Yervoy , 37% (95% CI: 31-44) for Opdivo alone and 17% (95% CI: 12-23) for Yervoy alone.

At 10 years of follow up, the objective response rate (ORR) was higher for the two Opdivo groups, in combination with Yervoy and alone, at 58.3% and 44.9%, respectively than the Yervoy group at 19.0%. The median duration of response (DoR) was not reached for those who received Opdivo plus Yervoy, while the median DoR was 103.2 months for Opdivo -treated patients and 19.2 months for Yervoy -treated patients. 1

The safety profile for Opdivo plus Yervoy was consistent with prior findings, with no new safety signals observed and no additional treatment-related deaths occurring since the prior three analyses. Grade 3/4 treatment-related adverse events were reported in 62.6% of patients in the combination group, 24.6% of patients in the Opdivo group, and 29.6% of patients in the Yervoy group.

Bristol Myers Squibb thanks the patients and investigators who have participated in the CheckMate -067 clinical trial.

About CheckMate -067

CheckMate -067 is a Phase 3, double-blind, randomized trial that evaluated the combination of Opdivo plus Yervoy or Opdivo monotherapy versus Yervoy monotherapy in 945 patients with previously untreated advanced melanoma. Patients in the combination group (n=314) received Opdivo 1 mg/kg plus Yervoy 3 mg/kg every three weeks (Q3W) for four doses followed by Opdivo 3 mg/kg every two weeks (Q2W). Patients in the Opdivo monotherapy group (n=316) received Opdivo 3 mg/kg Q2W plus placebo. Patients in the Yervoy monotherapy group (n=315) received Yervoy 3 mg/kg Q3W for four doses plus placebo. Patients were treated until progression or unacceptable toxic effects. Overall survival (OS) and progression-free survival (PFS) were dual primary endpoints of the trial. Secondary endpoints included objective response rates (ORR), descriptive efficacy assessments and safety.

About Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of the disease and occurs when cancer spreads beyond the surface of the skin to other organs. The incidence of melanoma has been increasing steadily for the last 30 years. Globally, the World Health Organization estimates that by 2035, melanoma incidence will reach 424,102, with 94,308 related deaths. In the United States, 100,640 new diagnoses of melanoma and about 8,290 related deaths are estimated for 2024. Melanoma can be mostly treatable when caught in its very early stages; however, survival rates can decrease as the disease progresses.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

About Yervoy

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune- mediated adverse reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and YERVOY. Monitor for signs and symptoms 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 periodically during treatment with OPDIVO and before each dose of YERVOY. 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 OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, 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 immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Some ocular IMAR 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, which has been observed in patients receiving OPDIVO and YERVOY, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.

Infusion-Related Reactions

OPDIVO and YERVOY can cause severe infusion-related reactions. Discontinue OPDIVO and YERVOY in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30- minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients.

In MPM patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, infusion-related reactions occurred in 12% (37/300) of patients.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO or YERVOY. 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 OPDIVO or YERVOY and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO and YERVOY prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action and findings from animal studies, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and YERVOY and for at least 5 months after the last dose.

Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone

In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Lactation

There are no data on the presence of OPDIVO or YERVOY in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment and for 5 months after the last dose.

"We are excited about our expanding library of mKRAS-specific rTCRs targeting different mutations and HLA allotypes, aiming to broaden treatment options and improve outcomes for patients with difficult-to-treat solid tumors," said Dolores Schendel, CSO at Medigene AG. "Our lead KRAS G12D candidate, enhanced by the costimulatory switch protein (CSP) PD1-41BB, has shown very promising T cell functionality. By overcoming the challenges of the tumor microenvironment that have hindered the effectiveness of TCR-T therapies, we are confident that this program could offer best-in-class efficacy and safety. We are expanding our TCR library and also incorporating new proprietary technologies into our End-to-End (E2E) Platform, including UniTope & TraCR, a universal detection system for any rTCR across various modalities like TCR-T therapies, TCR-guided T cell engagers therapies, and TCR-NK cell therapies. Direct integration of the UniTope tag guarantees 100% co-expression of a unique identifier in a rTCR sequence and provides a significant advancement over current methods for detection of rTCRs in TCR-guided therapeutics. UniTope and TraCR will help us streamline quality control and provide precise data for determining the correct drug dosage for TCR-T therapies."

Advancing a multi-dimension KRAS mutation-specific T cell receptor (TCR) library with a 3S TCR targeting the G12D mutation to address large global patient populations

The first data presented showcased recent advancements in the expansion of the Company’s KRAS library, using a high-throughput approach to develop optimal affinity TCRs targeting the mKRAS G12D neoantigen in the context of HLA-A*11 via Medigene’s proprietary E2E Platform. Further in vitro studies characterized the lead TCR candidate in terms of specificity, sensitivity, and safety (3S) while incorporating the PD1-41BB CSP. TCR-expressing T cells, when stimulated by mKRAS G12D-positive tumor cells, showed increased interferon gamma (IFNγ) release. Reduced cancer cell survival was observed when mKRAS G12D-positive tumor cell lines from various origins were exposed to T cells co-expressing the rTCR mKRAS G12D-HLA-A*11 and PD1-41BB CSP. These effects were specific to mKRAS G12D, with no impact on wild-type KRAS cells. The TCR demonstrated an excellent safety profile, with no off-target toxicity against an extensive panel of healthy cell types. Finally, in vitro data showed that co-expression of PD1-41BB CSP enhanced and sustained T cell function in an rTCR-specific manner, with gated activation that only occurred when the specific peptide-HLA complex was present on target cells, and not through PD-L1 expression alone.

UniTope & TraCR – Universal tagging and tracking system for TCR-T cells integrated directly in the TCR constant region

The second poster displayed the Company´s recently introduced universal TCR tagging and tracking combination technology UniTope & TraCR. Bioinformatic alignment of T cell receptor beta variable sequences enabled a six-amino-acid peptide (UniTope) to be predicted that is not found in natural TCR beta chains and has low immunogenicity. In parallel, an antibody was developed to specifically target this short amino acid peptide (TraCR) and further in vitro experiments demonstrated that TCR-T cells containing the UniTope sequence exhibited similar effects to those of TCR-T cells without the UniTope sequence. Integration of the UniTope sequence in a rTCR guarantees 100% co-expression of the tag and provides a significant advancement over current methods of detection of rTCRs in TCR-guided therapeutics.

In vitro studies confirmed that insertion of UniTope did not alter expression or functionality of rTCRs. In addition, safety assessments confirmed that UniTope-modified rTCRs displayed the same high safety profile as un-modified rTCRs with respect to lack of recognition and killing of 16 healthy cell types.
