Melflufen (melphalan flufenamide) is a first-in-class anticancer peptide-drug conjugate that rapidly delivers an alkylating payload into tumor cells. Melflufen is in late stage clinical development for a potential treatment of patients with relapsed refractory multiple myeloma (RRMM).

"The primary read-out of the HORIZON-data represents an important milestone for Oncopeptides. They lay the ground for the New Drug Application to the FDA, seeking accelerated approval for intravenous melflufen in combination with dexamethasone, says Klaas Bakker, CMO of Oncopeptides. "Melflufen could provide a novel treatment option with a unique mechanism of action for a group of myeloma patients with a particularly poor prognosis".

Below is a brief description of the abstracts that have been accepted by the European Hematology Association (EHA) (Free EHA Whitepaper). The full EHA (Free EHA Whitepaper) abstract book can be found on www.ehaweb.org.

HORIZON (OP-106): Melflufen plus dexamethasone in relapsed/refractory multiple myeloma (RRMM) refractory to pomalidomide and/or an anti-CD38 monoclonal antibody – primary and subgroup analysis.
Final Abstract Code: EP945. First author: Paul G Richardson.The primary read-out of the data from the pivotal, phase II study HORIZON demonstrates clinical efficacy and a manageable safety profile of the peptide-drug conjugate melflufen in combination with dexamethasone in patients with RRMM, including patients with high-risk features and triple-class–refractory disease.
HORIZON (OP-106): An exploratory analysis of time to next treatment in patients with relapsed/refractory multiple myeloma who received melflufen plus dexamethasone.
Final Abstract Code: EP1029. First author: Maria-Victoria MateosThe abstract includes a time to next treatment analysis: The sub-analysis of the HORIZON clinical study is the first to provide important insights on time to subsequent treatment in patients with advanced RRMM (medium 5 lines of previous lines).
LIGHTHOUSE (OP-108): A phase 3 study of melflufen in combination with daratumumab versus daratumumab in patients with relapsed/refractory multiple myeloma.
Final Abstract Code: PB2018. First author: Maria-Victoria MateosThe planned randomized phase 3 trial LIGHTHOUSE will study the impact of melflufen, dexamethasone and subcutaneous daratumumab compared with subcutaneous daratumumab alone. The results will be important to confirm the preliminary efficacy, safety and tolerability results from phase 1/2 ANCHOR study, combining melflufen, dexamethasone and daratumumab supporting further regulatory milestones for Oncopeptides
Adverse event and outcome patterns in patients with advanced multiple myeloma in the US
Final Abstract Code: PB2039. First author: Joshua RichterThis real-world data study provides evidence, that albeit introduction of additional treatment options for patients with advanced multiple myeloma, their prognosis remains poor and the need for additional treatment options are high
Melflufen is a highly effective anti-neoplastic agent in bortezomib-resistant multiple myeloma models.
Final Abstract Code: EP915. First author: Konstantin ByrgazovMelflufen is more efficacious in bortezomib-resistant myeloma cell lines than in their bortezomib-naive parental cells in vitro. Bortezomib-resistant myeloma cells lines overexpress Aminopeptidase B encoded by RNPEP gene, and myeloma patients with high RNPEP expression have shorter PFS on bortezomib-containing therapies.
Melflufen efficacy in multiple myeloma with TP53 aberrations.
Final Abstract Code: EP903. First author: Ana Slipicevic.Melflufen can trigger myeloma cell death regardless of cells TP53 status and overcome the p53-deficiency-mediated melphalan resistance. Melflufen response rate in the del 17p patient subpopulation from the phase 2-study HORIZON is comparable to the general RRMM population suggesting that melflufen might be a therapeutic option for these difficult-to-treat patients.
Aminopeptidase expression in multiple myeloma associates with disease progression and sensitivity to melflufen.
Final Abstract Code: EP897. First author: Juho MiettinenAminopeptidases play a role in multiple myeloma biology. Their expression levels are dysregulated during disease progression, and majority are increased in RRMM compared to NDMM patients. Aminopeptidases LAP3 and TPP2 are identified as prognostic markers in myeloma patients, and inhibition of aminopeptidases reduces myeloma cell viability in vitro. Melflufen, an aminopeptidase substrate, is a highly efficient anticancer agent in myeloma cells resistant to other alkylators, bortezomib and selinexor.

About melflufen
Melflufen (melphalan flufenamide) is a first-in-class anti-cancer peptide-drug conjugate that rapidly delivers an alkylating payload into tumor cells. Melflufen is rapidly taken up by myeloma cells due to its high lipophilicity and is immediately cleaved by peptidases to deliver an entrapped hydrophilic alkylator payload. Peptidases play a key role in protein homeostasis and feature in cellular processes such as cell-cycle progression and programmed cell death. In vitro, melflufen is 50-fold more potent in myeloma cells than the alkylator payload itself due to the increased intracellular alkylator concentration. Melflufen displays cytotoxic activity against myeloma cell lines resistant to other treatments, including alkylators, and has also demonstrated inhibition of DNA repair induction and angiogenesis in preclinical studies.

First Quarter 2020 Highlights and Subsequent Updates:

The U.S. FDA Granted Orphan Drug Designations for ALPN-101 in the Prevention and Treatment of Acute Graft Versus Host Disease. In March, the United States Food and Drug Administration (FDA) granted two orphan drug designations for ALPN-101, our first-in-class inhibitor of the CD28 and ICOS inflammation pathways, for the prevention of, and for the treatment of, acute GVHD.
ALPN-202 Study Design Presented at AACR (Free AACR Whitepaper). In April, Alpine presented the design of NEON-1, the first-in-human study of ALPN-202, our first-in-class clinical stage conditional CD28 costimulator and dual checkpoint inhibitor, at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) Virtual Annual Meeting I, in the Phase I Trials in Progress Virtual Poster Session.
ALPN-101 Preclinical Data in Inflammatory Bowel Disease (IBD) Presented at 2020 Crohn’s & Colitis Congress and Digestive Disease Week 2020. ALPN-101 modulated inflammatory cytokines in vitro from human IBD peripheral blood mononuclear cells (PBMC) more potently than CD28 or ICOS single-pathway inhibitors and significantly reduced disease activity in vivo in the CD4+CD45RBhi T cell transfer mouse colitis model.
ALPN-101 and ALPN-202 Clinical Trials Ongoing. A phase 1b/2 trial of ALPN-101 in acute GVHD (BALANCE, NCT04227938) has been initiated. The NEON-1 trial of ALPN-202 (NCT04186637) is open for enrollment.
"The first quarter was a highly productive one, with now two open clinical studies for both our lead product candidates," said Mitchell H. Gold, M.D., Executive Chairman and Chief Executive Officer of Alpine. "We were gratified to receive orphan drug designations for ALPN-101 in acute GVHD, where current standard therapies remain inadequate to prevent or control the disease. We also reiterate our excitement over ALPN-202, which is now poised clinically to address a potential key mechanism accounting for checkpoint inhibitor resistance."

First Quarter 2020 Financial Results

As of March 31, 2020, Alpine had cash, cash equivalents, restricted cash, and short-term investments totaling $36.1 million. Net cash used in operating activities for the first quarter ended March 31, 2020 was $9.7 million compared to $11.2 million for the first quarter ended March 31, 2019. Alpine recorded a net loss of $5.5 million and $12.4 million for the first quarters ended March 31, 2020 and 2019, respectively.
Research and development expenses for the first quarter ended March 31, 2020 were $4.9 million compared to $10.4 million for the first quarter ended March 31, 2019.
General and administrative expenses for the first quarter ended March 31, 2020 were $1.8 million compared to $2.3 million for the first quarter ended March 31, 2019.
Cash Guidance

Alpine expects to have sufficient cash to fund its planned operations for at least the next 12 months, including the clinical advancement of Alpine’s lead autoimmune/inflammatory program, ALPN-101, and its lead oncology program, ALPN-202.

For additional information regarding Alpine’s planned operations, please refer to "Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operation – Liquidity and Capital Resources" in Alpine’s Quarterly Report on Form 10-Q for the three months ended March 31, 2020, which Alpine anticipates filing with the Securities and Exchange Commission on or about May 14, 2020.

About ALPN-101

ALPN-101 is a novel Fc fusion protein of a human inducible T cell costimulator ligand (ICOSL) variant immunoglobulin domain (vIgD), a first-in-class therapeutic designed to inhibit simultaneously the CD28 and ICOS inflammation pathways. CD28 and ICOS are closely related costimulatory molecules with partially overlapping roles in T cell activation likely playing a role in multiple autoimmune and inflammatory diseases. In preclinical models of graft versus host disease, inflammatory arthritis, connective tissue disease, and multiple sclerosis, ALPN-101 demonstrates efficacy superior to agents blocking the CD28 – CD80/86 and/or ICOS – ICOSL pathways alone. A phase 1b/2 trial of ALPN-101 in acute GVHD (BALANCE, NCT04227938) has been initiated.

About ALPN-202

ALPN-202 is a first-in-class, conditional CD28 costimulator and dual checkpoint inhibitor with the potential to improve upon the efficacy of combined checkpoint inhibition while limiting significant toxicities. Preclinical studies of ALPN-202 have successfully demonstrated superior efficacy in tumor models compared to checkpoint inhibition alone. A phase 1 trial of ALPN-202 in advanced malignancies (NEON-1, NCT04186637) is open for enrollment.

On May 14, 2020 Achieve Life Sciences, Inc. (Nasdaq: ACHV), a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation and nicotine addiction, reported first quarter 2020 financial results and provided an update on the cytisinicline clinical development program (Press release, OncoGenex Pharmaceuticals, MAY 14, 2020, View Source [SID1234558038]).

Recent Highlights

Submitted required non-clinical supportive data for longer cytisinicline treatment to the U.S. Food & Drug Administration (FDA) in preparation for Phase 3 cytisinicline ORCA-2 trial initiation

Closed financing for gross proceeds of approximately $1.9 million, prior to deducting placement agent commissions and estimated offering expenses

Presented new findings from the Phase 2b ORCA-1 trial evaluating cytisinicline in U.S. smokers at the Society for Research on Nicotine & Tobacco (SRNT) Annual Conference

Established agreement with the FreeMind Group to assist in securing non-dilutive funding to evaluate cytisinicline in vapers and e-cigarette users

"The COVID-19 pandemic has revealed an increased risk for smokers due to the known relationship between smoking and respiratory illnesses and we see an even greater need to do all that we can to help them quit," commented Rick Stewart, Chairman and Chief Executive Officer of Achieve. "We expect to initiate the 750 patient Phase 3 ORCA-2 trial in the second-half of 2020, subject to financing and the ability to conduct the trial safely in light of the COVID-19 pandemic."

Completed FDA Submission

In preparation for initiation of the Phase 3 ORCA-2 clinical trial of cytisinicline, the Company has now submitted to FDA all requested non-clinical data to allow 6 and 12 weeks of cytisinicline treatment in the Phase 3 trials. No new safety or toxicology signals were observed in the non-clinical data evaluating either 13 or 26 weeks of cytisinicline treatment.

Closed private placement financing for gross proceeds of $1.9 million

In April 2020, Achieve announced it entered into definitive agreements for a private placement of its securities for gross proceeds of approximately $1.9 million, prior to deducting placement agent commissions and estimated offering expenses. The Company intends to use the proceeds to fund clinical research and development, and for general working capital.

Additional ORCA-1 Results at SRNT Annual Conference

An oral presentation featuring new ORCA-1 Phase 2b trial analyses was presented at the SRNT Annual Meeting in March 2020. In addition to previously reported data indicating a statistically significant improvement in quit rates, new analyses demonstrate cytisinicline biochemical efficacy via measurement of serum cotinine as well as the previous carbon monoxide efficacy. Additionally, further analyses confirm that cytisinicline benefit was observed across all clinical sites, baseline

characteristics, and attributes. Thus, regardless of trial site location, patient demographics, smoking history, or prior treatments, all subjects treated with cytisinicline showed similar smoking cessation benefit.

The ASCO (Free ASCO Whitepaper) poster, by Dr. Mohammed Milhem of the University of Iowa and coauthors, titled "AST-008: A Novel Approach to TLR9 Agonism with PD-1 Blockade for Anti-PD-1 Refractory Merkel Cell Carcinoma (MCC) and Cutaneous Squamous Cell Carcinoma (CSCC)" will be presented virtually in the Developmental Therapeutics—Immunotherapy Poster Session under abstract number TPS3164.

The poster will present details of the phase Ib/II trial of Exicure’s drug candidate, AST-008, a toll-like receptor 9 agonist oligonucleotide being developed for the treatment of MCC and CSCC in patients progressing on immune checkpoint inhibitor monotherapy.

Key features of the phase Ib/II trial described in the poster include:

Advanced/metastatic MCC and CSCC are skin cancers with high unmet medical need;
Data presented earlier suggest that AST-008 elicits a Th1-type cytokine response and immune cell activation;
The phase II dose escalation study will use the recommended dose of AST-008, administered intratumorally, in combination with pembrolizumab or cemiplimab to treat two cohorts of patients with advanced/metastatic MCC or CSCC respectively;
The enablement of a dose expansion of AST-008 plus cemiplimab in CSCC without having performed a separate dose escalation with the latter combination;
Each expansion cohort will enroll up to 29 patients across about 15 US-based sites;
Patients enrolled into the phase II will have to have progressed on a single-agent checkpoint therapy;
The key objective of the phase II expansion is to provide an estimate of preliminary efficacy of intratumorally administered AST in the trial subjects. Other endpoints include safety, pharmacokinetic and pharmacodynamic assessments.
About AST-008

AST-008 is an SNA consisting of toll-like receptor 9 agonists designed for immuno-oncology applications. As of January 31, 2020, we have dosed 17 patients in the Phase 1b stage of the clinical trial. We have observed no treatment related serious adverse events, nor have we observed any dose-limiting toxicity among the treated subjects. The most common reported adverse event was injection site reactions. In December 2019, we received preliminary results from the Phase 1b/2 stage of the clinical trial showing potential signs of anti-tumor activity in patients with Merkel cell carcinoma. In the second quarter of 2020, we plan to initiate a Phase 2 dose expansion for intratumoral AST-008 in combination with approved checkpoint inhibitors to treat two cohorts of patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. Each cohort is expected to enroll up to 29 patients who have failed anti-PD-1/PD-L1, or programmed cell death protein 1/programmed death-ligand 1, therapy. We expect to open a total of up to 15 sites in the United States.
