As of December 31, 2018, CytomX had cash, cash equivalents and short-term investments of $436.1 million, sufficient capital to fund its operating expenses and capital requirement into 2021.

"Over the last year, we have generated meaningful clinical proof of concept data for the Probody platform across both of our lead, wholly-owned programs," said Sean McCarthy, D.Phil., president, chief executive officer and chairman of CytomX Therapeutics. "As we showed at our inaugural Research and Development Day yesterday, our PD-L1 Probody therapeutic, CX-072, is active across a wide range of tumors and has a potentially differentiated safety profile as monotherapy and in combination. CX-2009, our first-in-class CD166 Probody Drug Conjugate, is well tolerated and has demonstrated anti-tumor activity across multiple tumor types. In 2019, we will continue to explore the full potential of these innovative product candidates as we maintain our intense focus on discovery, development and ultimate commercialization of a new generation of differentiated cancer therapeutics."

2018 Business Highlights and Recent Developments

PROCLAIM-CX-072 (PD-L1 Probody Therapeutic) Clinical Program

CX-072 is a Probody therapeutic targeting PD-L1, a clinically- and commercially-validated anti-cancer target.
Enrollment began in January 2017 in PROCLAIM-CX-072, a Phase 1/2 clinical trial evaluating CX-072 as monotherapy and in combination with YERVOY (ipilimumab) or Zelboraf (vemurafenib) in patients with cancer.
Enrollment is complete with follow-up continuing in the monotherapy dose escalation arm evaluating CX-072 in patients with advanced unresectable solid tumors or lymphomas (Part A) and in the monotherapy dose escalation arm in patients with PD-L1-positive tumors (Part A2).
Enrollment and follow-up are ongoing in the monotherapy expansion cohorts of CX-072 at 10 mg/kg in multiple indications (Part D).
Data from Parts A, A2 and D was presented most recently at CytomX’s 2019 Research and Development Day.
Additional data from Part D is expected in 2019.
Enrollment of the dose escalation arm combining CX-072 plus Yervoy (ipilimumab) in patients with advanced unresectable solid tumors or lymphomas (Part B) is complete and was presented most recently at CytomX’s 2019 Research and Development Day.
Enrollment is ongoing in the dose escalation combination arm of CX-072 plus Zelboraf (vemurafenib) in patients with V600E BRAF-positive melanoma (Part C).
PROCLAIM-CX-2009 (CD166 Probody Drug Conjugate) Clinical Program

CX-2009 is a Probody drug conjugate (PDC) that targets CD166, an antigen that is broadly and highly expressed in many types of cancer, and is conjugated with DM4, a clinically-validated toxin licensed from ImmunoGen.
Enrollment began in June 2017 in PROCLAIM-CX-2009, a Phase 1/2 clinical trial, evaluating CX-2009 as monotherapy in a subset of seven cancer types (Part A) and in patients selected for high level of CD166 expression (Part A2).
Preliminary data from Parts A and A2 was presented at CytomX’s 2019 Research and Development Day.
BMS-986249 (CTLA-4 Probody Therapeutic) Clinical Program

Bristol-Myers Squibb (BMS), continues enrollment in a Phase 1/2 clinical trial evaluating BMS-986249 alone and in combination with OPDIVO (nivolumab) in solid tumors that are advanced and have spread.
BMS has stated that they anticipate preliminary data from this trial in 2019.
CX-2029 (CD71 Probody Drug Conjugate) Clinical Program

CytomX, in collaboration with AbbVie, is advancing CX-2029, a CD71-directed Probody Drug Conjugate.
CD71, also known as the transferrin receptor 1 (TfR1), is highly expressed in a number of solid and hematologic cancers and has particularly attractive molecular properties for efficient delivery of cytotoxic payloads to tumor cells.
Enrollment began in late June 2018 in PROCLAIM-CX-2029, a Phase 1/2 clinical trial evaluating CX-2029 as monotherapy in patients with solid tumors or lymphomas and is ongoing.
CX-188 (PD-1 Probody Therapeutic) Program

CX-188 is a PD-1-directed Probody therapeutic.
PD-1 is the receptor for the PD-L1 ligand responsible for inhibiting T-cell activation in a variety of cancers and is a clinically- and commercially-validated anti-cancer target.
In October 2018, CytomX filed an Investigational New Drug Application (IND) with the Food and Drug Administration (FDA) on CX-188. The CX-188 IND was cleared by the FDA in November 2018. Due to a recent program and portfolio prioritization, the company has decided to indefinitely postpone the CX-188 clinical trials. The company may elect to initiate clinical trials of CX-188 in the future.
CytomX Technology Acquisition from Agensys, Inc.

In January 2019, CytomX announced the acquisition of drug conjugate linker-toxin and CD3-based bispecific technologies from Agensys, Inc., an affiliate of Astellas Pharma Inc.
CytomX Therapeutics 2019 Research and Development Day

CytomX hosted a Research and Development Day on Tuesday, February 26, 2019. A replay of the webcasted event is available under the "Investors & News" section of www.CytomX.com.

Full Year Financial Results

Cash, cash equivalents and short-term investments totaled $436.1 million as of December 31, 2018, compared to $374.1 million as of December 31, 2017.

Revenue was $59.5 million for the year ended December 31, 2018, compared to $71.6 million for the year ended December 31, 2017. The $12.1 million decrease is largely attributable to the recognition of $14.0 million in milestone revenue in 2017 from AbbVie (net of a $1.0 million license fee paid to SGEN) as a result of completion of certain milestones under the CD71 Agreement, the recognition of a $10 million milestone in 2017 from BMS related to the IND filing for BMS-986249, the recognition of $6.5 million in revenue in 2017 related to the delivery of the ImmunoGen 2017 License to ImmunoGen in connection with the ImmunoGen Research Agreement, a decrease of $4.5 million in the amortization of deferred revenue under the ImmunoGen Research Agreement which concluded on June 30, 2018, and a decrease of $0.5 million in revenues from Pfizer as a result of Pfizer terminating our Research Collaboration, Option and License Agreement in March 2018. These decreases were partially offset by the recognition of $11.7 million of revenue in 2018 related to the milestone payment of $21.0 million from AbbVie (net of the associated $4.0 million sublicense fee to SGEN) for the achievement of the IND filing success criteria under the CD71 Agreement, an increase of $7.9 million in amortization of deferred revenue in 2018 related to the $200.0 million upfront payment received in the second quarter of 2017 as a result of the extension of the BMS collaboration, and an increase of $3.6 million of revenue from Amgen under the Amgen Agreement entered into in September 2017.

Research and development expenses increased by $11.6 million during the year ended December 31, 2018 compared to the corresponding period in 2017. The increase was primarily attributed to an increase in lab services of $10.0 million and $12.3 million in clinical trial expenses related to CX-072, CX-2009 and CX-2029 Phase 1/2 clinical development. There was also an increase of $10.5 million in personnel related expenses; $1.2 million increase in allocation of information technology and facilities related expenses; $0.9 million in lab supplies and $0.7 in consulting expenses. These amounts were largely offset by the recognition, during the third quarter of 2017, of $10.7 million of non-cash in-process research and development expense; $12.1 million of sublicense fees payable to the University of California, Santa Barbara, as a result of both the $200 million upfront payment made by BMS in connection with the expanded collaboration and the Amgen Agreement and a $1.0 million sublicense fee to ImmunoGen upon commencement of enrollment of Phase 1/2 and first patient dosing in the clinical trial for CX-2009 in the second quarter of 2017.

General and administrative expenses increased by $7.9 million during the year ended December 31, 2018 compared to the corresponding period in 2017. This increase was largely attributed to an increase of $5.6 million in personnel related expenses due to increases in headcount, and $2.3 million for various consulting and other services.
