The Company expects patient enrollment to begin in the fourth quarter of 2020.Presented Preliminary Phase 1 Study Results of ALX148 in Combination with Rituximab in Patients with Refractory Non-Hodgkin Lymphoma. In June 2020, ALX Oncology presented preliminary results from the fully enrolled ALX148 plus rituximab combination cohort of the Phase 1 clinical program at the 25th Annual Congress of European Hematology Association [abstract #EP1247]. Thirty-three patients with relapsed or refractory non-Hodgkin Lymphoma (NHL) were administered ALX148 at 10 or 15 mg/kg once per week in combination with standard rituximab regimen. No exposure-dependent cytopenias were observed, and a greater response rate was observed in the higher dosing cohort of heavily pre-treated subjects with NHL.
 Presented Phase 1 Study Results of ALX148 in Combination with Standard Anti-Cancer Antibodies and Chemotherapy Regimens in Patients with Advanced Solid Tumors. In May 2020, ALX Oncology announced final results from the fully enrolled ALX148 plus pembrolizumab and ALX148 plus trastuzumab portions of the Phase 1 clinical trial at the 2020 American Society of Clinical Oncology Annual Meeting [Abstract #3056]. Eighty-nine patients with advanced solid tumors were administered ALX148 in combination with standard regimens of: 1) pembrolizumab, 2) trastuzumab, 3) pembrolizumab plus 5-fluorouracil plus platinum, or 4) trastuzumab plus ramucirumab plus paclitaxel. Expansion cohorts were comprised of patients with previously treated advanced head and neck squamous cell carcinoma (HNSCC) and advanced gastric/gastroesophageal junction cancer (G/GEJ) demonstrated objective responses. ALX148 displayed a favorable tolerability profile with no exposure-dependent cytopenia observed across the dose range evaluated. Preliminary data suggest that ALX148 can be combined with chemotherapy-containing regimens with objective responses observed in patients with HNSCC and G/GEJ disease. Future clinical development will focus upon evaluating these combinations in patients with previously untreated disease as well as later line disease.Second Quarter 2020 Financial Results:Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2020, were $98.1 million. Including the net proceeds from the Company’s IPO of $172.7 million, after deducting underwriting discounts and commissions, the Company believes its cash balance is sufficient to fund planned operations through 2023.
 Related-party Revenue: Related-party revenue for the quarter ended June 30, 2020, was $0.5 million compared to $1.3 million for the corresponding period in 2019. The decrease in related-party revenue relates to decreased fee-for-service hours provided to Tallac Therapeutics (“Tallac”) as a result of winding down the research and development agreement, which terminated in July 2020. Due to the changes in the arrangement with Tallac, the Company will no longer recognize any related-party revenue beginning with the third quarter of 2020.  
 Research and Development (“R&D”) Expenses: R&D expenses consist primarily of pre-clinical, clinical and manufacturing expenses related to the development of ALX148.  These expenses for the three months ended June 30, 2020, were $7.7 million, compared to $3.6 million for the three months ended June 30, 2019. The increase of $4.0 million was primarily attributable to an increase of $2.3 million in non-cash stock-based compensation expense, mainly resulting from modification of awards for former employees that transferred to Tallac, as well as increased clinical supply manufacturing costs of $1.4 million and increased clinical development personnel costs of $0.3 million.
 General and Administrative (“G&A”) Expenses: G&A expenses consist primarily of administrative employee-related expenses, legal and other professional fees, patent filing and maintenance fees, and insurance. These expenses for the three months ended June 30, 2020, were $3.2 million, compared to $0.7 million for the prior-year period. This increase of $2.5 million was primarily due to increased headcount, and increased accounting, legal and other professional fees of $1.4 million to support the transition to a public company, and $0.6 million related to non-cash stock-based compensation expense from the modification of awards for a former employee that transferred to Tallac and additional stock option awards granted during the second quarter.
 Net loss: Net loss attributable to common stockholders was $14.0 million and $5.2 million for the three months ended June 30, 2020, and 2019, respectively. Included in the $14.0 million loss for the three months ended June 30, 2020, was $2.6 million related to cumulative dividends allocated to preferred shareholders, which, along with prior cumulative dividends, were converted into common shares at the IPO. Non-GAAP net loss was $8.1 million and $4.1 million for the three months ended June 30, 2020, and 2019, respectively.  A reconciliation of GAAP to non-GAAP financial results can be found in a table at the end of this news release.About ALX OncologyALX Oncology is a clinical-stage immuno-oncology company focused on helping patients fight cancer by developing therapies that block the CD47 checkpoint pathway and bridge the innate and adaptive immune system.
