Despite Setback, Iovance's Lifileucel Remains A Multibillion Dollar Prospect
Iovance Biotherapeutics, in an attempt to secure FDA-approval for their biologic, lifileucel, in advanced melanoma, was set back as the FDA requires some more information.This can't come to much of a surprise to investors, as Iovance's TIL therapy carries a complex manufacturing and delivery process compared to your typical drug.While the company figures BLA submission will be pushed back to 2021, investors need not lose sight of what is likely to be a blockbuster biologic once it clears all hurdles.Iovance remains an interesting speculative biotechnology investment as it continues to advance TIL therapy into the market.

Checkmate Pharmaceuticals Announces Data Presentations for CMP-001 at The Society for Immunotherapy of Cancer (SITC) 35th Anniversary Annual Meeting
CMP-001 in combination with pembrolizumab continues to demonstrate durable responses in anti-PD-1 refractory melanoma Encouraging new data on pathological responses and 1-year RFS with neoadjuvant CMP-001 and nivolumab in resectable Stage III melanomaCAMBRIDGE, Mass., Oct. 15, 2020 (GLOBE NEWSWIRE) -- Checkmate Pharmaceuticals, Inc. (NASDAQ: CMPI) (“Checkmate”), a clinical stage biotechnology company focused on developing proprietary technology to harness the power of the immune system to combat cancer, today announced new data presentations evaluating CMP-001, Checkmate’s Toll-like receptor 9 (TLR9) agonist, at The Society for Immunotherapy of Cancer (SITC) 35th Anniversary Annual Meeting to be held virtually November 9-14, 2020.The abstracts for these presentations appeared briefly on the SITC website in error prior to their intended release on November 9, 2020, and as a result are provided in full below.“These data continue to demonstrate the compelling clinical activity and manageable safety profile of CMP-001 in combination with anti-PD-1 antibodies in patients with melanoma,” said Dr. James Wooldridge, Chief Medical Officer at Checkmate Pharmaceuticals. “Of particular note, we are encouraged by the maturing results in the neoadjuvant study that will be presented by Dr. Davar, including a pathological response rate (pCR, pMR, pPR) of 70%, and a 1-year relapse-free survival of 82%, which trended higher in patients achieving a pathological response.”Presentation Details (presented without modification below):Title: Intratumoral injection of CMP-001, a Toll-like receptor 9 (TLR9) agonist, in combination with pembrolizumab reversed programmed death receptor 1 (PD-1) blockade resistance in advanced melanoma Presenting Author: Mohammed Milhem Abstract : 579 Location: Virtual Poster Hall November 11-14, 9:00am – 5:00pm ETFull abstract: Background: Therapeutic options are limited for patients with advanced melanoma that is refractory to PD-1 blockade. This study was performed in this patient population to assess the safety and antitumor activity of CMP-001, a CpG-A TLR9 agonist packaged within a virus-like particle.Methods: Patients were eligible for this 2-part, open-label, multicenter, phase 1b study if they had metastatic/unresectable melanoma and stable disease after ≥12 weeks or progressive disease (PD) on/after anti−PD-1 therapy. Part 1 evaluated CMP-001 plus pembrolizumab dose-escalation and dose-expansion. Part 2 evaluated CMP-001 monotherapy. Accessible lesion(s) were injected intratumorally with CMP-001, at a polysorbate 20 (PS20) concentration of either 0.01% or 0.00167%. The Part 1 primary objective was to identify the recommended phase 2 dose (RP2D) and schedule of CMP-001 plus pembrolizumab, while the Part 2 primary objective was to assess the safety of CMP-001 monotherapy. Secondary objectives for both parts were a preliminary assessment of antitumor activity of CMP-001 plus pembrolizumab and CMP-001 monotherapy, and the overall safety profile and pharmacodynamics of the combination.Results: In Part 1 (N=159) and Part 2 (N=40), 93.1% and 80.0% of patients had PD as their last response to prior anti–PD-1 therapy, respectively. The most common treatment-related adverse events (TRAEs; >25%) were flu-like symptoms (Parts 1 and 2) and injection-site reactions (Part 1). Grade 3/4 TRAEs were reported in 36.5% (Part 1) and 22.5% (Part 2) of patients, the most common being hypotension (Part 1: 6.9%; Part 2: 5.0%). No Grade 5 TRAEs were observed.In Part 1, the best objective response rate (ORR; RECIST v1.1) in patients treated with pembrolizumab and CMP-001 (PS20 0.01%) was 23.5% (23/98), while CMP-001 PS20 (0.00167%) resulted in a lower ORR of 11.5% (7/61). Seven additional patients had a delayed response after initial PD (Table). The median duration of response was >1 year. In the 37 RECIST v1.1 and post-progression responders, the mean regression in injected and noninjected target lesions was 54.7% and 52.7%, respectively. In Part 2, the best ORR with CMP-001 monotherapy was 17.5% (7/40 patients); the response duration was shorter than in Part 1. Intratumoral CMP-001 PS20 0.01% 10 mg was selected as the RP2D.Conclusion: Intratumoral CMP-001 was well-tolerated and provided both local and distant responses in patients with advanced melanoma with disease progression on prior PD-1 blockade. CMP-001 monotherapy induced systemic tumor regression in some patients, but duration of response was substantially increased by the addition of pembrolizumab.Title: Phase II Trial of Neoadjuvant Nivolumab (Nivo) and Intra-Tumoral (IT) CMP-001 in High-Risk Resectable Melanoma (Neo-C-Nivo) Presenting Author: Diwakar Davar Abstract : 612 Location: Virtual Oral Presentation November 11, 5:30 – 6:30pm ETFull Abstract: Background: Neoadjuvant PD-1 blockade produces major pathological responses (MPR) in ~30% of patients (pts) with high-risk resectable melanoma (MEL) with durable relapse-free benefit, and increased circulating activated CD8+ T cells [1,2]. CMP-001 is a type A CpG packaged within a virus-like particle that activates tumor-associated plasmacytoid dendritic cells (pDC) via TLR9 inducing type I interferons and anti-tumor CD8+ T cells. CMP-001/pembrolizumab produces durable anti-tumor responses in PD-1 refractory melanoma [3]. We previously reported preliminary evidence of efficacy of neoadjuvant IT CMP/Nivo in high-risk resectable MEL; and herein present final results on 30 evaluable patients.Methods: 30 pts with stage III B/C/D MEL were enrolled. Pre-operatively, CMP-001 was dosed at 5mg subcutaneous (SC, 1st), then 10mg IT (2nd-7th) weekly; and Nivo was dosed 240mg q2weeks for 3 doses – both over a 7-week period. Post-operatively, Nivo was dosed 480mg q4weeks with CMP-001 5mg q4 weeks SC for 48 weeks. Primary endpoints included major pathologic response (MPR) rate, and incidence of dose-limiting toxicities (DLT). Secondary endpoints were radiographic response, relapse-free survival (RFS) and overall survival (OS). Pathological response was scored by blinded pathologist based on residual volume of tumor (RVT) using prior cutoffs [4-6]: 0% (complete response, pCR); 0%50% (non-response, pNR). Radiographic response was assessed using RECIST v1.1. Sequential blood draws and tumor biopsies were collected and analyzed for CD8+ T cell infiltrate (TIL), multiparameter flow cytometry (MFC) and multiplex immunofluorescence (mIF).Results: 30 pts with advanced MEL were enrolled, and staged as: IIIB (57%), IIIC (37%), IIID (7%). 29/30 (97%) of pts completed 7 weeks of neoadjuvant Nivo/CMP; while 1 pt had a delay in surgery related to a pre-operative infection unrelated to therapy. No DLTs were reported; although grade 3/4 irAE were reported in 3 pts (11%) leading to CMP-001 discontinuation in 2 pts (7%). Radiographic responses seen in 13 pts (43%), while 9 pts (30%) had stable disease and 8 pts (27%) had progressive disease. Pathological responses (RVT <50%) were seen in 70% of pts: pCR 15 (50%), pMR 3 (10%), 3 pPR (10%); while 9 (30%) had pNR. Pathological responders (pCR/pMR) had increased CD8+ TIL and CD303+ pDC intra-tumorally by mIF; and activated PD1+/Ki67+ CD8+ T cells by MFC peripherally.Conclusions: Neoadjuvant CMP/Nivo has an acceptable toxicity profile and promising efficacy. MPR rate is 60% in 30 pts. 1-year RFS was 82% (all pts) and 89% (pCR/pMR); and median RFS is 9 months (pNR/pPR) and unreached (pCR/pMR). Response is associated with evidence of immune activation intra-tumorally and peripherally. IT CMP001 together increases clinical efficacy of PD-1 blockade alone with minimal additional toxicity in neoadjuvant MEL.Title: Intravenous CMP-001, a CpG-A Toll-like receptor 9 (TLR9) agonist delivered via a virus-like particle, causes tumor regression in syngeneic Hepa1-6 mouse models of hepatocellular carcinoma Presenting Author: Arthur M. Krieg Abstract : 418 Location: Virtual Poster Hall November 11-14, 9:00am – 5:00pm ETFull Abstract: Background: Therapeutic options are limited for patients with liver metastases and hepatocellular carcinoma (HCC). Intratumoral and subcutaneous injections of CMP-001, a CpG-A TLR9 agonist packaged within a virus-like particle, have shown evidence of antitumor activity in patients with melanoma refractory to PD-1 blockade. In mice, CMP-001 intravenous distributes primarily to the liver, while CMP-001 subcutaneous is found mostly in local tissues and draining lymph nodes. The antitumor activity of CMP-001 intravenous and subcutaneous were compared with PD-1 blockade or sorafenib in two Hepa1-6 orthotopic mouse models of HCC.Methods: Groups of 10-15 C57BL/6J mice were orthotopically implanted with syngeneic murine hepatoma cells using two different models. Model 1 used 1.5 x 106 Hepa1-6 cells injected into the spleen following a partial hepatectomy; Model 2 used 1 x 106 Hepa1-6-Luc cells injected into the upper left lobe of intact liver. Treatment was initiated 3-7 days later with either CMP-001 intravenous or subcutaneous Q4-5Dx3-4 doses, PD-1 blocking antibody intraperitoneal Q3-4Dx2 (Bio X Cell clone RPM1-14), or sorafenib QD oral. Antitumor activity was assessed by tumor imaging, liver weight, and/or survival.Results: CMP-001 was compared with PD-1 blocking antibody therapy in Model 1, the more aggressive model. All animals were sacrificed at day 15 due to institutional welfare requirements. Tumor growth inhibition (TGI) was assessed by comparison of liver weight to body weight ratios, which relative to untreated control mice showed that CMP-001 intravenous achieved 85% mean TGI compared with 63% mean TGI for CMP-001 subcutaneous and 15% mean TGI for PD-1 blocking antibody intraperitoneal (Table 1). CMP-001 intravenous was compared to sorafenib oral in Model 2, which utilized an engineered Hepa1-6 cell line that expresses luciferase to enable noninvasive monitoring of liver tumor growth. CMP-001 intravenous was active, with a 67% mean TGI, and survival that was comparable to sorafenib (Table 2; Figure 1).Conclusion: In orthotopic mouse models of HCC, the antitumor activity of CMP-001 intravenous was greater than PD-1 blockade and comparable to sorafenib. CMP-001 intravenous was more active than CMP-001 subcutaneous in this model, which we hypothesize is due to increased liver exposure with intravenous infusion. Antitumor activity of CMP-001 monotherapy may be increased by combining it with standard of care or other therapies, as observed relative to historical benchmarks in ongoing CMP-001 clinical trials in patients with melanoma. CMP-001 intravenous may be a promising treatment option for patients with primary or metastatic liver cancers.About CMP-001CMP-001 comprises a virus-like particle utilizing a CpG-A oligonucleotide.
