CytomX Therapeutics Announces Full-Year 2017 Financial Results and Provides Operational Update
As of December 31, 2017, CytomX had cash, cash equivalents and short-term investments of $374.1 million. Based upon its current operating plan, the Company expects its existing capital resources will be sufficient to fund operations into 2020.
“The CytomX team continued tremendous execution during 2017, driving our transition to a clinical-stage company with the initiation of Phase 1/2 studies for two wholly-owned and one partnered program,” said
“During 2018, we expect initial data readouts from our PD-L1-targeting Probody therapeutic, CX-072, and our CD166-targeting Probody drug conjugate, CX-2009. We also expect to initiate clinical studies for two additional programs this year, resulting in five clinical-stage Probody therapeutic programs by year end. Our deepening pipeline of innovative therapeutics has the potential to make a meaningful difference in the lives of people with cancer,” continued Dr. McCarthy.
2017 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 2017in 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 in the monotherapy dose escalation arm evaluating CX-072 in patients with advanced unresectable solid tumors or lymphomas (Part A).
- Preliminary data from Part A is expected to be presented mid-2018.
- Patient enrollment was initiated at a single dose level in an expansion cohort in an undisclosed cancer with known sensitivity to PD-pathway inhibitors (Part D).
- Patient enrollment is ongoing in all other dose escalation arms of the study:
- Monotherapy expansion in patients with PD-L1-positive tumors at multiple dose levels (Part A2);
- Combination of CX-072 plus Yervoy® (ipilimumab) in patients with advanced unresectable solid tumors or lymphomas (Part B);
- Combination 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.
- Patient enrollment continues in the PROCLAIM-CX-2009 study, a Phase 1/2 clinical trial initiated in
June 2017, evaluating CX-2009 as monotherapy in a subset of CD166-positive cancer types (Part A).
- Preliminary data from Part A is expected to be presented in the second half of 2018.
- Monotherapy expansion at select dose levels and in the same subset of cancers has been initiated in patients selected for the highest levels of CD166 expression (Part A2).
BMS-986249 (CTLA-4 Probody Therapeutic) Clinical Program
Bristol-Myers Squibb(BMS) presented preclinical safety and anti-tumor activity data for an anti-CTLA-4 Probody therapeutic designed to be a potentially safer ipilimumab.
- In fourth quarter of 2017, BMS initiated a Phase 1/2 study evaluating BMS-986249 alone and in combination with nivolumab in solid tumors that are advanced and have spread.
- BMS-986249 is the first Probody therapeutic to advance to the clinic under the companies’ strategic collaboration.
CX-2029 (CD71 Probody Drug Conjugate) Preclinical Program
- CytomX, in collaboration with AbbVie, is advancing CX-2029, a CD71-directed PDC, through Investigational New Drug (IND) application-enabling studies.
- 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.
- CytomX expects to file an IND application for CX-2029 in the first half of 2018.
CX-188 (PD-1 Probody Therapeutic) Preclinical Program
- CytomX is advancing CX-188, a PD-1-directed Probody therapeutic, through IND-enabling studies.
- 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.
- CytomX expects to file an IND application for CX-188 in the second half of 2018.
- During the third quarter of 2017, CytomX received a $15 million milestone payment (
$14 millionnet of associated license fees) from AbbVie in conjunction with meeting certain criteria allowing the initiation of GLP toxicology studies by CytomX for CX-2029, a CD71-directed PDC.
- During the third quarter of 2017, Amgen and CytomX entered into a strategic collaboration in immuno-oncology in the field of Probody T-cell engaging bispecific antibodies (Pro-TCBs), including the co-development of a CytomX Pro-TCB against the Epidermal Growth Factor Receptor (EGFR), a highly validated oncology target expressed on multiple human cancer types.
- Under the terms of the agreement, Amgen and CytomX will co-develop a Pro-TCB against EGFR-CD3 with CytomX leading early development.
- Amgen will lead later development and commercialization with global late-stage development costs shared between the two companies.
- Amgen made an upfront payment of $40 million and purchased $20 million of CytomX common stock.
- CytomX is eligible to receive up to $455 million in development, regulatory and commercial milestones payments for the EGFR program and low-double digit to mid-teen percentage royalty payments on resulting EGFR products, and has the ability to opt into a profit share in the U.S.
Amgenis also able to select three additional targets for Pro-TCB discovery and development. Should Amgenultimately pursue all of these targets, CytomX will be eligible to receive up to $950 millionin additional upfront and milestone payments and high-single digit to low-teen percentage royalty payments on any resulting products.
- CytomX also received the rights from
Amgento an undisclosed preclinical T-cell engaging bispecific program; Amgenis eligible to receive milestones and mid-single digit to low-double digit percentage royalty payments on any resulting products from this CytomX program.
Bristol-Myers Squibb Collaboration Expansion
- During the second quarter of 2017, CytomX and BMS expanded its foundational alliance to discover, develop and commercialize novel therapies using the Probody platform, resulting in a $200 million upfront payment to CytomX.
- The expanded collaboration now provides BMS with the selection of up to ten oncology targets and two non-oncology targets.
- In the fourth quarter of 2017, CytomX earned a
$10 millionmilestone payment from BMS upon IND clearance of BMS-986249.
March 6, 2018, CytomX received notification of Pfizer’s intent to terminate the companies’ research collaboration, option and license agreement.
- The Pfizer collaboration, entered into in 2013, included the selection of up to four PDC targets for the treatment of cancer.
- The initial PDC target was EGFR, which Pfizer previously discontinued, with certain rights reverting to CytomX.
- Collaboration programs against the second and third targets were terminated during the first quarter of 2018.
- Pfizer had previously declined its option to select a fourth target in the collaboration.
- None of the programs in the Pfizer collaboration had advanced to clinical candidate stage.
