CytomX Therapeutics Announces Third Quarter 2019 Financial Results and Provides Business Update

SOUTH SAN FRANCISCO, Calif., Nov. 07, 2019 (GLOBE NEWSWIRE) -- CytomX Therapeutics, Inc. (Nasdaq: CTMX), a clinical-stage oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody™ therapeutic technology platform, today reported third quarter 2019 financial results.

As of September 30, 2019, CytomX had cash, cash equivalents and short-term investments of $325.7 million.

“The CytomX clinical pipeline made excellent progress in Q3 as we continued to advance multiple Probody therapeutic programs across the portfolio,” said Sean McCarthy, D.Phil., president, chief executive officer and chairman of CytomX Therapeutics. “The initiation of a Phase 2 trial of our anti-PD-L1 Probody CX-072 in combination with ipilimumab in patients with relapsed refractory melanoma marks our ongoing evolution into a product-focused company seeking to realize the full potential of our novel technology platform. Our first in class Probody Drug Conjugate programs, CX-2009 and CX-2029, also continued to move forward and our pipeline overall is positioned for significant data updates in 2020.” 

Business Highlights and Recent Developments

CX-072 Anti-PD-L1 Probody Therapeutic Clinical Program

  • In October, CytomX announced the initiation of the PROCLAIM (Probody Clinical Assessment In Man) CX-072-002 Phase 2 study evaluating the efficacy and tolerability of the anti-PD-L1 Probody CX-072, in combination with the anti-CTLA-4 antibody, ipilimumab, in patients with relapsed or refractory melanoma. The study utilizes a Simon Two-Stage design with approximately 40 patients being enrolled into Stage 1. CytomX anticipates initial data from Stage 1 in 2020.  Additional information on this trial is available at using the identifier NCT03993379.
  • The Company also announced in October updated clinical data from the Phase 1 PROCLAIM-CX-072-001 dose-finding study of CX-072 in combination with ipilimumab. With enrollment complete, 27 evaluable patients had received ipilimumab (3, 6 or 10 mg/kg) combined with CX-072 (0.3, 1, 3 or 10 mg/kg), with the study achieving a disease control rate (stable disease or better) of 37%.  5 patients achieved confirmed objective responses by RECIST v1.1, including one complete response, for an overall response rate (ORR) of 19% in this heavily pretreated patient population.  The median duration of response was 14.6 months (1.9 - 21.2 months) with 4 of the 5 responders still on treatment as of the latest data snapshot. Of the 27 patients treated across all doses, Grade 3/4 treatment related adverse events (TRAEs) were reported in 9 (33%) patients.  Grade 3/4 immune-related adverse events (irAEs) were reported in 3 (15%) patients.
  • Enrollment within the monotherapy cohorts of the PROCLAIM-CX-072-001 study is complete with evaluation of the activity and tolerability of CX-072 monotherapy continuing with ongoing treatment in select cohorts. Additional information on this trial is available at using the identifier NCT03013491.

CX-2009 Anti-CD166 Probody Drug Conjugate Clinical Program

  • CytomX anticipates announcing next steps for the PROCLAIM-CX-2009 clinical program by the end of 2019. 

BMS-986249 Anti-CTLA-4 Probody Therapeutic Clinical Program

  • Bristol-Myers Squibb (BMS) is conducting a Phase 1/2a dose escalation clinical study evaluating BMS-986249 alone and in combination with OPDIVO® (nivolumab) in advanced solid tumors.
  • BMS is preparing to initiate the Phase 2 portion of this clinical trial, upon which CytomX is entitled to a $10 million milestone payment. Additional information on this trial is available at using the Identifier NCT03369223.

CX-2029 Anti-CD71 Probody Drug Conjugate Clinical Program

  • CytomX continued enrollment of patients in the PROCLAIM-CX-2029 Phase 1/2 study, which is partnered with AbbVie, evaluating CX-2029 as monotherapy in patients with solid tumors or lymphomas. Additional information on this trial is available at using the Identifier NCT003543813.

Additional Corporate Highlights

  • In October, the Company announced the appointment of Amy C. Peterson, M.D., as executive vice president and chief development officer. In this new role, Dr. Peterson will have oversight of a multi-disciplinary team focused on advancing all aspects of CytomX’s clinical development activities. 
  • In July, the Company announced that its partner AbbVie selected a second target under the companies’ 2016 Discovery Collaboration and Licensing Agreement to discover and develop Probody drug conjugates. The target selection triggered a $10 million payment to CytomX from AbbVie.

Third Quarter 2019 Financial Results
Cash, cash equivalents and short-term investments totaled $325.7 million as of September 30, 2019, compared to $436.1 million as of December 31, 2018. 

Revenue was $10.7 million for the three months ended September 30, 2019, compared to $12.5 million for the three months ended September 30, 2018.  The decrease in revenue of $1.8 million for the three months ended September 30, 2019 compared to the corresponding period in 2018 was primarily due to a $1.7 million decrease in revenue recognition under the CD71 Agreement with AbbVie due to ongoing dose escalation. 

Research and development expenses increased $0.4 million during the three months ended September 30, 2019 compared to the corresponding period in 2018. The increase was attributable to an increase of $1.3 million in personnel-related expenses primarily due to an increase in headcount; an increase of $0.7 million in consulting expenses resulting from increased clinical trial activities and an increase of $0.8 million in the allocation of information technology and facilities related expenses driven partly from an increase in headcount; which amounts were offset by a decrease of $2.4 million in laboratory contracts and services and laboratory supplies as a result of timing of manufacturing activities as well as reduced costs relating to CX-188 which is not presently being advanced.

General and administrative expenses increased by $0.3 million during the three months ended September 30, 2019 compared to the corresponding period in 2018. The increase was attributable to an increase of $0.4 million in consulting expenses primarily related to IT, software implementation and finance services; an increase of $0.5 million in dues and subscriptions primarily related to software and other IT services; an increase of $0.2 million in building maintenance charges; which amounts were partially offset by a decrease of $0.8 million of information technology and facilities-related expenses allocated to the general and administrative functions.

About CytomX Therapeutics

CytomX Therapeutics is a clinical-stage oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody™ therapeutic technology platform. Probody therapeutics are designed to exploit unique conditions of the tumor microenvironment to more effectively localize antibody binding and activity while minimizing activity in healthy tissues. CytomX and its partners have four programs in the clinic.  The Company’s clinical stage pipeline includes cancer immunotherapies against clinically validated targets, including a PD-L1-targeting Probody therapeutic wholly owned by CytomX (CX-072) and a CTLA-4-targeting Probody therapeutic partnered with Bristol Myers Squibb (BMS-986249). The CytomX clinical stage pipeline also includes first-in-class Probody drug conjugates against highly attractive targets, including a CD166-targeting Probody drug conjugate wholly owned by CytomX (CX-2009), and a CD71-targeting Probody drug conjugate partnered with AbbVie (CX-2029). CD166 and CD71 are among cancer targets that are considered to be inaccessible to conventional antibody drug conjugates due to their presence on many healthy tissues. In addition to its wholly owned programs, CytomX has strategic collaborations with AbbVie, Amgen, Bristol-Myers Squibb Company and ImmunoGen, Inc. For more information, visit

CytomX Therapeutics Forward-Looking Statements
