"Building upon the encouraging data generated with mirvetuximab monotherapy, we have looked to expand our addressable patient population through combination regimens with both currently approved and experimental agents in ovarian cancer. In dose escalation, we have demonstrated that full dose mirvetuximab can be combined safely with full doses of Avastin, carboplatin, or Keytruda, with encouraging preliminary clinical activity," said Anna Berkenblit, MD, Vice President and Chief Medical Officer of ImmunoGen. "The promising new data reported in the FORWARD II Avastin and carboplatin arms support the potential of mirvetuximab combinations in earlier lines of therapy. Together, these results have informed the triplet combination study with mirvetuximab plus carboplatin and Avastin, which we initiated last quarter."

Berkenblit continued, "In addition, we plan to present initial data from the Keytruda expansion cohort later this year, building upon the dose escalation data recently presented at SGO. The totality of these data from FORWARD II will guide the next stages of development of mirvetuximab and support a path to registration for combination regimens."

DATA FROM FORWARD II EXPANSION COHORT WITH AVASTIN

Mirvetuximab soravtansine in combination with Avastin in patients with platinum-resistant ovarian cancer has demonstrated anti-tumor activity with durable responses and a favorable tolerability profile, particularly among the subset of patients who have received up to three prior lines of therapy and have medium or high levels of FRα expression. This is the population being studied in the FORWARD I Phase 3 registration trial.

Key findings in 59 patients with platinum-resistant ovarian cancer include:

In the subset of 23 patients evaluable for response with medium or high FRα expression levels who have received up to three prior lines of therapy, the confirmed overall response rate (ORR) was 48 percent (95% CI 27,69), with a median progression-free survival (PFS) of 9.9 months (95% CI 4.6,14.5) and a median duration of response (DOR) of 10.6 months (95% CI 3.3,12.0).

For the 54 patients evaluable for response, the confirmed ORR was 43 percent (95% CI 29,57), with a median PFS of 7.8 months (95% CI 5.6,10.2); patients in this cohort had received a median of 3 prior lines of systemic therapy, with 58 percent of patients having received prior bevacizumab.

The combination continues to display a safety profile in-line with the known profiles of each agent, with no new safety signals identified.

"The mirvetuximab and Avastin combination has demonstrated very encouraging initial clinical activity in ovarian cancer patients and a consistently favorable safety profile," stated David O’Malley, M.D., Professor, Director of Gynecology Clinical Trial and Phase 1 Program, James Cancer Center and The Ohio State University Wexner Medical Center, and FORWARD II Investigator. "There is a significant need for new therapeutic options to improve outcomes and tolerability for this difficult-to-treat patient population, and I believe these results support further clinical evaluation of this combination regimen."

UPDATED DATA FROM FORWARD II DOSE-ESCALATION COHORT WITH CARBOPLATIN

Initial findings from a dose escalation cohort of mirvetuximab in combination with carboplatin were presented at ASCO (Free ASCO Whitepaper) 2017. The data have matured and updated findings in heavily pre-treated patients with platinum-sensitive ovarian cancer include:

In the subset of 10 patients with medium or high FRα expression levels, the confirmed ORR was 80 percent (95% CI 44,98), with a median PFS of 15 months (95% CI 9.9,-), and with median DOR not reached.

For all 17 evaluable patients, the confirmed ORR was 71 percent (95% CI 44,90), with a median PFS of 15 months (95% CI 9.9, -), and with median DOR not reached; 50 percent of patients in this cohort had received 3 or more prior lines of systemic therapy.

The combination continues to display a favorable safety profile in-line with the known profiles of each agent, with no new safety signals identified.

Based on the findings from the carboplatin and Avastin cohorts, ImmunoGen recently initiated an additional cohort assessing a triplet combination of mirvetuximab plus carboplatin and Avastin in patients with recurrent platinum-sensitive ovarian cancer as part of the FORWARD II trial.

DATA FROM FORWARD II DOSE-ESCALATION COHORT WITH KEYTRUDA

Additionally, ImmunoGen recently announced encouraging activity and favorable tolerability data from the FORWARD II cohort assessing mirvetuximab in combination with Merck’s anti-PD-1 therapy Keytruda (pembrolizumab) in patients with platinum-resistant ovarian cancer at the Society of Gynecologic Oncology Annual Meeting. Based on these data, ImmunoGen is completing enrollment in an expansion cohort that includes an additional 35 patients with medium or high FRα expression levels. ImmunoGen plans to report initial findings from this cohort in the second half of this year.

ABOUT FORWARD II

FORWARD II is a Phase 1b/2 study of mirvetuximab in combination with Avastin (bevacizumab), carboplatin or Keytruda (pembrolizumab) in patients with FRα-positive platinum-resistant ovarian cancer, primary peritoneal, or fallopian tube tumors, as well as a triplet combination of mirvetuximab plus carboplatin and Avastin in patients with platinum-sensitive ovarian cancer.

ABOUT MIRVETUXIMAB SORAVTANSINE

Mirvetuximab soravtansine (IMGN853) is the first folate receptor alpha (FRα)-targeting ADC. It uses a humanized FRα-binding antibody to target the ADC specifically to FRα-expressing cancer cells and a potent anti-tumor agent, DM4, to kill the targeted cancer cells.

On May 16, 2018 Innate Pharma SA (the "Company" – Euronext Paris: FR0010331421 – IPH) last night reported preliminary data from an ongoing Phase I dose escalation and expansion study evaluating the safety and efficacy of the combination of monalizumab, a first-in-class monoclonal antibody targeting NK- and T cell checkpoint receptor NKG2A, with durvalumab (Press release, Innate Pharma, MAY 16, 2018, View Source [SID1234526741]).

Data show preliminary anti-tumor activity in patients with recurrent, metastatic colorectal cancer, with 3 partial responses and 11 stable disease responses among 37 patients evaluable for efficacy, with a disease control rate of 24% at 16 weeks (data cut as of February 8, 2018). The data also showed a manageable toxicity profile.

The Phase I dose escalation and expansion study enrolled a total of 55 patients. In the dose-escalation part, 15 patients with selected solid tumors received durvalumab 1500 mg every 4 weeks in combination with monalizumab at increasing doses. In the expansion phase, 40 patients with microsatellite-stable colorectal cancer (MSS-CRC) were enrolled. 58% of patients in expansion had 3+ lines of prior therapy.

These data were highlighted in an abstract (#3540) published online on May 16 by the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in advance of its annual meeting in Chicago, Illinois, June 1-5, 2018. The abstract is available on the ASCO (Free ASCO Whitepaper) website. A poster (#33) with updated clinical data will be presented at ASCO (Free ASCO Whitepaper) in the Gastrointestinal (Colorectal) Cancer session in Hall A on Sunday, June 3 between 8:00am and 11:30am.

Based on these preliminary results, Innate’s partner AstraZeneca/MedImmune progressed the combination with standard of care therapies

On May 16, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported follow-up data from the phase III ALEX study, showing that, as an initial treatment, Alecensa (alectinib) significantly reduced the risk of disease progression or death (progression-free survival; PFS) by 57% (hazard ratio [HR]= 0.43, 95% CI: 0.32-0.58) compared to crizotinib after two years of follow-up in people with anaplastic lymphoma kinase (ALK)-positive metastatic (advanced) non-small cell lung cancer (NSCLC), as assessed by the investigator (Press release, Hoffmann-La Roche, MAY 16, 2018, View Source [SID1234526740]).1 The median PFS for people who received Alecensa was more than tripled compared to those who received crizotinib (34.8 months [95% CI: 17.7 months-NE) versus 10.9 months [95% CI: 9.1-12.9 months)], respectively, as assessed by the investigator. The safety profile for Alecensa was consistent with that observed in previous studies.

"Follow-up results from the ALEX study demonstrate the significant sustained benefit of Alecensa, showing that people with metastatic ALK-positive non-small cell lung cancer lived for almost three years without their disease progressing," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "These results further support the use of Alecensa as a standard of care for people who are newly diagnosed with this form of lung cancer."

The longer-term analysis also included follow-up data for secondary endpoints of the ALEX study. Alecensa demonstrated superior efficacy compared to crizotinib regardless of the presence of central nervous system (CNS) metastases at baseline. Investigator-assessed median PFS for people without CNS metastases at baseline was 34.8 months with Alecensa (95% CI: 22.4-NE) versus 14.7 months (95% CI: 10.8-20.3) with crizotinib (HR=0.47, 95% CI: 0.32-0.71). Investigator-assessed median PFS for people with CNS metastases at baseline was 27.7 months in the Alecensa arm (95% CI: 9.2-NE) versus 7.4 months (95% CI: 6.6-9.6) in the crizotinib arm (HR=0.35, 95% CI: 0.22-0.56). 1 The duration of response (DOR) for people who received Alecensa was 33.3 months (95% CI: 31.3-NE) compared to 11.1 months (95% CI: 7.5-13.0 months) for people who received crizotinib.1

The data will be presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting on Sunday, 3 June, 2018 at 08:00 – 11:30 am CDT (Abstract #9043).

Alecensa is now approved in more than 45 countries as an initial (first-line) treatment for ALK-positive, advanced NSCLC, including in the United States, Europe and Japan.

About the ALEX study2
ALEX (NCT02075840/B028984) is a randomised, multicentre, open-label, phase III study evaluating the efficacy and safety of Alecensa versus crizotinib in treatment-naïve people with ALK-positive NSCLC whose tumours were characterised as ALK-positive by the VENTANA ALK (D5F3) CDx Assay, a companion immunohistochemistry (IHC) test developed by Roche Tissue Diagnostics. People were randomised (1:1) to receive either Alecensa or crizotinib. The primary endpoint of the ALEX study was PFS as assessed by the investigator, and secondary endpoints include: Independent Review Committee (IRC)-assessed PFS, time to CNS progression, objective response rate (ORR), DOR and overall survival (OS). The multicentre study was conducted in 303 people across 161 sites in 31 countries. OS data are currently considered immature with only about a third of events being reported.

Primary data from the ALEX study were previously presented at the 2017 ASCO (Free ASCO Whitepaper) Annual Meeting and published in the New England Journal of Medicine.3 Follow-up results from the ALEX study analysis to be presented at the 2018 ASCO (Free ASCO Whitepaper) Annual Meeting showed1:

After a further 10 months of follow-up, Alecensa reduced the risk of disease worsening or death (PFS) by 57% compared to crizotinib (HR=0.43, 95% CI: 0.32-0.58). Median follow-up was 27.8 months versus 22.8 months for Alecensa-treated patients and crizotinib-treated patients, respectively.
Investigator-reported median PFS (the primary endpoint) was 34.8 months in the Alecensa arm (95% CI: 17.7-NE) versus 10.9 months (95% CI: 9.1-12.9 months) in the crizotinib arm.
ORR for people treated with Alecensa was 82.9% (95% CI: 75.95-88.51) compared to 75.5% (95% CI: 67.84-82.12) for people treated with crizotinib, as assessed by the investigator.
Alecensa demonstrated superior efficacy compared to crizotinib regardless of the presence or absence of CNS metastases at baseline. Investigator-assessed median PFS for people without CNS metastases at baseline was 34.8 months with Alecensa (95% CI: 22.4-NE) versus 14.7 months (95% CI: 10.8-20.3) with crizotinib (HR=0.47, 95% CI: 0.32-0.71). Investigator-reported median PFS for people with CNS metastases at baseline was 27.7 months in the Alecensa arm (95% CI: 9.2-NE) versus 7.4 months (95% CI: 6.6-9.6) in the crizotinib arm (HR=0.35, 95% CI: 0.22-0.56).
Improvements were observed in the time between first response to treatment and disease worsening (DOR): 33.3 months with Alecensa versus 11.1 months with crizotinib.
Grade 3-5 adverse events (AEs) were less frequent in the Alecensa arm (44.7%) compared to the crizotinib arm (51.0%). The most common Grade 3-4 AEs were increased liver enzymes (aspartate transaminase; 5.5%, and alanine transaminase; 4.6%) and increased muscle enzymes (creatine phosphokinase; 3.3%). Serious adverse reactions reported in ≥ 2% of people treated with Alecensa were acute kidney injury (2.6%) and decreased red blood cells (anaemia; 2.0%).
AEs leading to dose reduction (16.4% versus 20.5%) and dose interruption (22.4% versus 25.2%) were lower in the Alecensa arm compared with the crizotinib arm. AEs leading to discontinuation were equal in both arms (13.2%).
The FDA approval of Alecensa for the treatment of people with ALK-positive metastatic NSCLC was based on results from the phase III ALEX study from the primary data cutoff in February 2017. Results showed that:

Alecensa significantly reduced the risk of disease worsening or death (PFS) by 47% (HR=0.53, 95% CI: 0.38-0.73, p<0.001) compared to crizotinib as assessed by an IRC.
The median PFS was 25.7 months (95% CI: 19.9-NE) for people who received Alecensa compared with 10.4 months (95% CI: 7.7-14.6) for people who received crizotinib as assessed by an IRC.
Alecensa significantly reduced the risk of the cancer spreading to, or growing in, the brain or CNS compared to crizotinib by 84% (HR=0.16, 95% CI: 0.10-0.28, p<0.0001). This was based on a time to CNS progression analysis in which there was a lower risk of progression in the CNS as the first site of disease progression for people who received Alecensa (12%) compared to people who received crizotinib (45%).
The safety profile of Alecensa was consistent with that observed in previous studies.
Grade ≥ 3 adverse reactions were reported for 41% of people treated with Alecensa. The most common Grade 3-4 adverse reactions (≥ 3%) were evidence of kidney dysfunction (increased creatinine; 4.1%), evidence of liver dysfunction (hyperbilirubinemia; 5%), low levels of sodium (hyponatremia; 6%), increased liver enzymes (aspartate transaminase; 6%, and alanine transaminase; 6%), and decreased red blood cells (anaemia; 7%). Serious adverse reactions reported in ≥ 2% of people treated with Alecensa were pneumonia (4.6%) and renal impairment (3.9%).
About Alecensa
Alecensa (RG7853/AF-802/RO5424802/CH5424802) is a highly selective, CNS active, oral medicine created at Chugai Kamakura Research Laboratories and is being developed for people with NSCLC whose tumours are identified as ALK-positive. ALK-positive NSCLC is often found in younger people who have a light or non-smoking history.4 It is almost always found in people with a specific type of NSCLC called adenocarcinoma.4 Alecensa is now approved in over 45 countries as an initial (first-line) treatment for ALK-positive, metastatic NSCLC, including in the United States, Europe, Japan, Turkey, Cuba, Peru, Thailand, Australia, the Dominican Republic, India, Israel, Paraguay, Switzerland, Bolivia, Serbia, South Korea and Singapore. In addition, Alecensa is approved in the United States, Europe, Japan, Kuwait, Israel, Hong Kong, Canada, South Korea, Switzerland, India, Bolivia, Australia, Singapore, Taiwan, Thailand, Liechtenstein, Argentina, United Arab Emirates, Saudi Arabia, Peru, New Zealand, Cuba, the Dominican Republic, Qatar, Oman, Serbia, Paraguay and Turkey for the treatment of people with advanced (metastatic) ALK-positive NSCLC whose disease has worsened after, or who could not tolerate treatment with, crizotinib.

About Roche in lung cancer
Lung cancer is a major area of focus and investment for Roche, and we are committed to developing new approaches, medicines and tests that can help people with this deadly disease. Our goal is to provide an effective treatment option for every person diagnosed with lung cancer. We currently have four approved medicines to treat certain kinds of lung cancer and more than ten medicines being developed to target the most common genetic drivers of lung cancer or to boost the immune system to combat the disease.

On May 16, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported positive results from the Phase III IMpower150 study of Tecentriq (atezolizumab) and Avastin (bevacizumab) plus carboplatin and paclitaxel (chemotherapy) for the initial (first-line) treatment of chemotherapy-naïve people with metastatic non-squamous non-small cell lung cancer (NSCLC) (Press release, Hoffmann-La Roche, MAY 16, 2018, View Source [SID1234526738]). This interim analysis showed that Tecentriq and Avastin plus carboplatin and paclitaxel helped people live significantly longer compared with Avastin plus carboplatin and paclitaxel (median overall survival [OS] = 19.2 versus 14.7 months; hazard ratio [HR] = 0.78, 95% CI: 0.64-0.96; p=0.016) in the intention-to-treat wild-type (ITT-WT) population, a co-primary endpoint of the study.1 An OS advantage was observed in all pre-specified exploratory biomarker-selected subgroups analysed, which included people with EGFR- and ALK-positive mutations who had received an appropriate targeted therapy, and those with varying levels of PD-L1 expression or with negative PD-L1 expression. People with liver metastases treated with the Tecentriq combination also had a survival advantage. The safety profile of the Tecentriq and Avastin plus carboplatin and paclitaxel combination was consistent with the safety profiles of the individual medicines, and no new safety signals were identified with the combination.

"The IMpower150 study results showed a significant survival benefit, adding to the clinical evidence supporting the combination of Tecentriq and Avastin as an initial treatment for metastatic non-squamous non-small cell lung cancer. An overall survival benefit was also observed in key populations such as people with EGFR- and ALK-positive mutations and those with liver metastases," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We are working with health authorities around the world to bring this potential Tecentriq combination regimen to people living with this disease."

At this interim analysis, the combination of Tecentriq plus carboplatin and paclitaxel (Arm A) did not show a statistically significant OS benefit when compared to the combination of Avastin plus carboplatin and paclitaxel (Arm C). Arm A will continue as planned to the final analysis. Safety in the Tecentriq plus carboplatin and paclitaxel arm appeared consistent with the known safety profile of the individual medicines, and no new safety signals were identified with the combination.

The official data presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting will be on Monday, June 4, 2018, at 15:45 – 15:57 p.m. CDT (Abstract #9002).

The combination of Tecentriq and Avastin plus carboplatin and paclitaxel was recently granted Priority Review from the U.S. Food and Drug Administration (FDA) for the initial (first-line) treatment of chemotherapy-naïve people with metastatic non-squamous NSCLC. The FDA is expected to make a decision on approval by September 5th, 2018.

IMpower150 is one of eight Phase III lung cancer studies underway, evaluating Tecentriq alone or in combination with other medicines. Following the IMpower150 and IMpower131 studies, three more Phase III lung cancer studies are expected to report this year.

About the IMpower150 study
IMpower150 is a multicentre, open-label, randomised, controlled Phase III study evaluating the efficacy and safety of Tecentriq in combination with chemotherapy (carboplatin and paclitaxel) with or without Avastin in people with stage IV or recurrent metastatic non-squamous NSCLC who had not been treated with chemotherapy for their advanced disease. It enrolled 1,202 people of which those with ALK and EGFR mutations were excluded from the primary ITT analysis. People were randomised (1:1:1) to receive:

Tecentriq plus carboplatin and paclitaxel (Arm A), or
Tecentriq and Avastin plus carboplatin and paclitaxel (Arm B), or
Avastin plus carboplatin and paclitaxel (Arm C, control arm).
During the treatment-induction phase, people in Arm A received Tecentriq administered intravenously at 1200 mg in combination with intravenous infusion of carboplatin and paclitaxel on Day 1 of a 3-week treatment cycle for 4 or 6 cycles. Following the induction phase, people received maintenance treatment with Tecentriq (1200 mg every 3 weeks) until loss of clinical benefit or disease progression. IMpower150 was designed to formally compare Tecentriq plus chemotherapy (Arm A) versus Avastin plus chemotherapy (Arm C), only if Tecentriq and Avastin plus chemotherapy (Arm B) is shown to improve OS in the ITT-WT population compared to Avastin plus chemotherapy (Arm C).

People in Arm B received induction treatment with Tecentriq (1200 mg) and Avastin administered intravenously at 15 mg/kg in combination with intravenous infusion of carboplatin and paclitaxel on Day 1 of a 3-week treatment cycle for 4 or 6 cycles. People then received maintenance treatment with the Tecentriq Avastin regimen until disease progression (Avastin) or loss of clinical benefit/disease progression (Tecentriq).

People in Arm C received induction treatment with Avastin administered intravenously at 15 mg/kg plus intravenous infusion of carboplatin and paclitaxel on Day 1 of a 3-week treatment cycle for 4 or 6 cycles. This was followed by maintenance treatment with Avastin alone until disease progression.

The co-primary endpoints were PFS and OS, as determined by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). The co-primary OS endpoint in IMpower150 was assessed in all randomised people without an EGFR or ALK genetic mutation (intention-to-treat wild-type). Key secondary endpoints included investigator-assessed PFS, OS and safety in the ITT population and in EGFR and ALK mutation subgroups. The study met its co-primary endpoints of OS and PFS per study protocol.

A summary of OS results is included below.

The safety profile of the Tecentriq and Avastin plus carboplatin and paclitaxel combination was consistent with the safety profiles of the individual medicines, and no new safety signals were identified with the combination. Serious adverse events (Grade 3-4) related to treatment were observed in 57% of people who received Tecentriq and Avastin plus carboplatin and paclitaxel compared to 49% of those who received Avastin plus carboplatin and paclitaxel.

About NSCLC
Lung cancer is the leading cause of cancer death globally.2 Each year 1.59 million people die as a result of the disease; this translates into more than 4,350 deaths worldwide every day.3 Lung cancer can be broadly divided into two major types: NSCLC and small cell lung cancer. NSCLC is the most prevalent type, accounting for around 85% of all cases.3 NSCLC comprises non-squamous and squamous-cell lung cancer, the squamous form of which is characterised by flat cells covering the airway surface when viewed under a microscope. The squamous form tends to grow near the centre of the lung, and accounts for approximately 25-30% of all NSCLC cases.4

About Tecentriq (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1 expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T-cells. Tecentriq has the potential to be used as a foundational combination partner with cancer immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers.

Currently, Roche has eight Phase III lung cancer studies underway, evaluating Tecentriq alone or in combination with other medicines.

Tecentriq is already approved in the European Union, United States and more than 70 countries for people with previously treated metastatic NSCLC and for people with locally advanced or metastatic urothelial cancer (mUC) who are not eligible for cisplatin chemotherapy, or who have had disease progression during or following platinum-containing therapy.

About Avastin (bevacizumab)
Avastin is a prescription-only medicine that is a solution for intravenous infusion. It is a biologic antibody designed to specifically bind to a protein called vascular endothelial growth factor (VEGF) that plays an important role throughout the lifecycle of the tumour to develop and maintain blood vessels, a process known as angiogenesis. Avastin is designed to interfere with the tumour blood supply by directly binding to the VEGF protein to prevent interactions with receptors on blood vessel cells. The tumour blood supply is thought to be critical to a tumour’s ability to grow and spread in the body (metastasise).

About the Tecentriq (atezolizumab) and Avastin (bevacizumab) combination
There is a strong scientific rationale to support the use of Tecentriq plus Avastin in combination. The Tecentriq and Avastin regimen may enhance the potential of the immune system to combat first-line advanced NSCLC. Avastin, in addition to its established anti-angiogenic effects, may further enhance Tecentriq’s ability to restore anti-cancer immunity, by inhibiting VEGF-related immunosuppression, promoting T-cell tumour infiltration and enabling priming and activation of T-cell responses against tumour antigens.

About Roche in cancer immunotherapy
For more than 50 years, Roche has been developing medicines with the goal to redefine treatment in oncology. Today, we’re investing more than ever in our effort to bring innovative treatment options that help a person’s own immune system fight cancer.

By applying our seminal research in immune tumour profiling within the framework of the Roche-devised cancer immunity cycle, we are accelerating and expanding the transformative benefits with Tecentriq to a greater number of people living with cancer. Our cancer immunotherapy development programme takes a comprehensive approach in pursuing the goal of restoring cancer immunity to improve outcomes for patients.

On May 16, 2018 Endocyte, Inc. (Nasdaq:ECYT), a biopharmaceutical company developing targeted therapeutics for personalized cancer treatment, reported that a poster with data from the Peter MacCallum Cancer Centre will be presented on Endocyte’s lead investigational therapy at the 2018 ASCO (Free ASCO Whitepaper) Annual Meeting on Saturday, June 2, 2018 (Press release, Endocyte, MAY 16, 2018, View Source [SID1234526737]). Updated data from the phase 2 study of 177Lu-PSMA-617 as a potential treatment for metastatic castration-resistant prostate cancer (mCRPC), including data from an additional 20 patient expansion cohort, will be highlighted by the poster.

"We are very pleased that we continue to see high rates of PSA response, even in heavily pre-treated patients," said Mike Sherman, president and CEO of Endocyte. "In the 50 patients receiving 177Lu-PSMA-617, 62% had a greater than 50% reduction in their PSA levels. Further, 44% of patients had a PSA reduction of 80% or greater. We look forward to sharing more information on this phase 2 trial at ASCO (Free ASCO Whitepaper). We recently reported median overall survival of 13.5 months for the first cohort of 30 patients enrolled. The median overall survival in the total 50 patients is not yet meaningful as follow-up in the second cohort of 20 patients is between 6 and 9 months at the time of cutoff. Updated survival metrics will be presented at a future medical conference as that data matures."
